The technical field to which the invention relates

The present invention relates to a transmission device, reception device and data transmission method, and more particularly to a transmission device capable of transmitting and receiving data using a variety of frequencies, the reception device and transmission method.

Prior art

Currently, in the field of mobile communication systems communication systems during exercise (CDMA multiple access code division multiple access) as the multiple access scheme. On the other hand, the research in relation to mobile communication systems of the next generation was very active, aimed at faster wireless data transfer. For example, 3GPP (Partnership Project Third Generation), which develops standards for mobile communication systems of the third generation, is working on the standardization of new technical requirements for mobile communication systems, referred to as LTE (Long term Development) (for example, see non-patent Literature 1).

The mobile communication system of the next generation, as expected, use OFDMA (Multiple access orthogonal frequency division multiplexing) or SC-FDMA (multiple access frequency division multiplexing with a single carrier) as schema mnozhestvennom the access. Such a mobile communication system plan data transfer for uplink communications from the mobile station to the base station as follows.

When the mobile station has the management information and other data for transmission, the base station performs dynamic allocation radioresource as in the frequency domain and in time domain for channel data transmission in uplink communication. Then the base station provides the mobile station with the distribution radioresource. According to this result, the mobile station transmits the management information and other data as distributed on the frequency and distributed time intervals.

When the mobile station has only the management information for the transfer, on the other hand, the mobile station is not allocated resources for data transmission channel in the ascending line of communication and it transmits the management information to the base station on the control channel of the ascending line who is a radio resource pre-installed for transmission of control information. The management information, which is transmitted via uplink communication includes ACK (Acknowledgement)/NACK (Negative acknowledgement), which is a response to the data from the base station, and CQI (Quality Indicator Channel), which is a measure of the quality of communication on the downlink (for example, see non-patent Literature 2).

Incidentally, the base station preferably distributes the frequency range with the best quality of communication upward communication for data transfer channel for uplink communications from the available bandwidth between the base station and mobile station. So before allocates resources for channel data transmission in uplink communication, the mobile station must transmit to the base station of the broadband pilot signal (SRS: Sounding Reference Signal), which is used to measure the quality of communication upward communication. In this case, the problem arises of how to multiplex information management and SRS, when the same or a different mobile station transmit them simultaneously. To solve the problem, there was proposed the following scheme of multiplexing (e.g., see non-patent Literature 3).

Fig illustrates an example of signals uplink communication, including SRS. In this example, according Fig ACK is transmitted as control information from the two frequency bands of the channels i and j control the ascending line. The mobile station is allowed to use one of these channels i and j control the upward communication line to transmit the management information. For each control channel ascending Lin is her communication signal, specifies the management information and the pilot signal (RS (Reference Signal)) are planned in a predetermined order. However, in the predetermined part of the unit period of time all the frequency bands are reserved as radioresource to transmit SRS. When the transmission of the SRS, the mobile station uses the reserved resource in a predetermined part of the unit period of time.

Problems that should be solved by the invention

However, the scheme of multiplexing in time to be used in non-patent Literature 3 does not allow for the transmission of information management at the same time as the broadband signal that should be used to measure the communication quality. Therefore, compared with the case of demultipleksirovanie broadband signal and the signal control information, this scheme provides less radioresource available in each unit period of time, for each channel uplink communication. This causes problems is that the quality of reception of the signal indicating the management information, is declining in the pickup device (corresponding to the above base station for uplink communication), and that the number of transfer devices (corresponding to the above described mobile station on the uplink communication), which can be covered by each control channel is reduced.

The present invention was made in view of the preceding description and should provide a transmission device, reception device and transmission method, which can prevent deterioration in the quality of transmission and reception of data, even when the measurement of the quality of communication using a broadband signal, and transmitting and receiving data using a predefined frequency range, are performed at the same time.

A means for solving problems

In order to solve the above problems, the present invention provides a transmission device, illustrated in figure 1. The transmission device 1 can perform data transmission at the first frequency, and data communications on the second frequency. The transmission device 1 includes a transmitter 1a, which transmits a signal, which should be used by the transmission device 2 for measuring communication quality in a given part of the first period of time in the frequency range that is wider p is the experience of frequencies, than the one used for data transmission, and does not include the first frequency, and transmits the signal in a given part of the second period of time occurring after the first period of time, in the frequency range, which has a wider frequency band than that used for data transmission, and does not include the second frequency.

With such a device 1 of the transmission signal which should be used to measure the quality of communication is transmitted in a given part of the first time period in the range of frequencies that has a wider bandwidth than such data, and does not include the first frequency. Then, the signal that should be used to measure the quality of communication is transmitted in a given part of the second period of time occurring after the first period of time, in the frequency range, which has a wider bandwidth than such data, and does not include the second frequency.

Additionally, in order to solve the above problems, provides a pickup device, illustrated in figure 1. The device 2 admission is intended for communication with the transmission device 1, which is able to perform data transmission at the first frequency, and data communications on the second frequency. The device 2 admission includes unit 2a of the measurement quality, which ISM is lose the quality of communication with the transmission device 1 on the basis of the signal, transferred in a given part of the first time period in the range of frequencies that has a wider bandwidth than the one used for data transmission, and does not include the first frequency, and on the basis of the signal transmitted in a given part of the second period of time occurring after the first period of time, in the frequency range, which has a wider frequency band than that used for data transmission, and does not include the second frequency.

The device 2 can measure the quality of communication with the transmission device 1 on the basis of the signal transmitted in a given part of the first period of time, in the frequency range, which has a wider bandwidth than such data, and does not include the first frequency, and the signal transmitted in a given part of the second period of time occurring after the first period of time, in the frequency range, which has a wider bandwidth than such data, and does not include the second frequency.

Advantages of the invention

According to the present invention, the signal that should be used to measure the quality of communication is transmitted in the first time period in the range of frequencies that does not include the first frequency, and then transmitted in the second time period in the range is Ascot, which does not include the second frequency. Therefore, there is a range of frequencies without interference signal in each of the first and second periods of time. This can prevent deterioration in quality during transmission and reception of data. In addition, the use of the signal transmitted in the first time period and transmitted in the second time period, allows to measure the quality of a wide range of frequencies.

Best mode for carrying out the invention

Further, embodiments of the present invention is described in detail with reference to the accompanying drawings. The description begins with an overview of option exercise, which will be discussed in the present description, and then goes into the details of these embodiments.

Figure 1 illustrates the overview of option exercise. The communication system in figure 1 is designed to transmit and receive data on multiple frequencies and includes the transmission device 1 and device 2 admission.

The transmission device 1 is a device for data transmission, which transmits the data via radio to the device 2 admission. The transmission device 1, for example, is equivalent to the mobile station system mobile phone. The transmission device 1 includes a transmitter 1a, which provides 2 reception signal, which should be used to measure the quality of the radio communication device 1 of the transmission device 2 admission.

In more detail,the transmitter 1a transmits a broadband signal, which occupies a wider frequency range than the one used for data transmission in a given part of the first time period in the range of frequencies that does not include the first frequency. Then the transmitter 1a transmits a broadband signal in a given part of the second period of time occurring after the first period of time, in the frequency range that does not include the second frequency.

The device 2 is a data device that receives data through radio communication device 1 of the transmission. The device 2 receiving, for example, is equivalent to the base station system mobile phone. The pickup device 2 includes unit 2a of the measurement quality. Unit 2a of the measurement quality measures the quality of the radio communication device 1 of the transmission device 2 admission on the basis of the broadband signal received from the transmission device 1 in the first and second periods of time. The measured communication quality can be used as an index to select the frequency range, which, for example, must be distributed to the transmission device 1.

In such a communication system, the transmitter 1a of the transmission device 1 uses the frequency range that does not include the first frequency in a given part of the first period of time, and uses a frequency band that is not on the includes a second frequency in a given part of the second time period, for transmission of the wideband signal. Then, block 2a quality measurement device 2 measures the reception quality of the radio communication device 1 of the transmission device 2 admission on the basis of the broadband signal received in the first and second periods of time.

In General, the measurement of communication quality needs a signal in a wide frequency range. However, if the transmitted signal occupies the entire frequency band available for transmission of data between the transmission device 1 and device 2 receiving, sending and receiving data let (delayed) during this transfer. The above technique allows the use of at least the first frequency without interference of the broadband signal during a first time period and to use at least a second frequency without interference of the broadband signal during a second period of time.

Therefore, this method makes it possible to prevent deterioration in communication quality due to the reduction in the period of time available for sending and receiving data. Additionally, the device 2 can use the broadband signal passed in the first and second time periods, which allow you to measure the quality of a wide range of frequencies.

(The first version of the implementation)

Below the first version of the implementation is described in detail with reference to the accompanying drawings.

<> Figure 2 illustrates the system configuration according to a variant implementation. The mobile communication system according to a variant implementation is a system of radio transmission in which the transmitted packet data. System for mobile communications figure 2 includes a mobile station 100 and 100a and the base station 200.

The mobile station 100 and 100a, for example, are mobile phones. Being in the range of communication (cell) of the base station, the mobile station 100 and 100a can perform radio communication with the base station, to transmit and receive packet data from neillyustrirovanny computer or another mobile station through the base station. Packet data that the mobile station 100 and 100a transmit and receive, include data VoIP (Minutes "speech on the Internet), e-mail data and image data.

The base station 200 continuously monitors the mobile station existing in the cell, and performs wired or radio communication with other base stations, where it is appropriate. After receiving the request for radio transmission (radio) from the mobile station existing in the cell, or request radio data communication with a mobile station existing in the cell, the base station 200 transmits and receives various information management and packet data from the mobile station.

Figure 3 - this is the block diagram, illustrating functions of a mobile station according to the first variant implementation. The mobile station 100 includes a transmitting and receiving antenna 110, the processor 120 of the data processor 130 pilot signal, the processor 140 information management unit 150 of the resource selection, the transmitter 160, a receiver 170 and block 180 to measure the quality of the descending line.

The transmitting and receiving antenna 110 is the antenna, which should be used for transmission and reception and which is intended for transmission via a radio uplink communication, the output from the transmitter 160, the base station 200 signals downlink transmitted via radio communication from the base station 200, and transmitting signals to the receiver 170.

The processor 120 generates data packet data that must be transmitted by radio, encodes and outputs the data. For example, the processor 120 generates data VoIP data, mail data, image data, etc. in response to operational inputs from a user of the mobile station 100. The processor 130 pilot signal generates various types of pilot signals. The coding pattern is determined for each type of pilot signals. The pilot signals generated by the processor 130 pilot signal includes the SRS to be used for measuring communication quality p the uplink connection.

The processor 140 information management generates the management information that must be transmitted by radio, encodes and outputs information according to the prescribed rules. Information management, which generates the processor 140 of the control information that includes the ACK/NACK, which is a response to the packet data from the base station, the CQI, which is a measure (measure) the quality of communication on the downlink, the request distribution radioresource uplink communication, etc. More specifically, when is the measurement of the communication quality on the downlink from block 180 measure the quality of downlink, the processor 140 information management generates CQI.

Block 150 selection controls the uplink radio resource connection available for the mobile station 100. Block 150 selections from time to time receives from the receiver 170 information management (information providing distribution UL)indicating the radio resource uplink communication, the distributed base station 200. In addition, the block 150 of the resource selection provides the transmitter 160 information on the distribution radioresource.

The transmitter 160 identifies radioresource that should be used for packet data, the pilot signal and the control information on the basis of information in the RA the distribution provided by block 150 of resource selection. Then the transmitter 160 modulates and multiplexes the packet data signal, the pilot signal and the signal control information, and outputs the result to the transmitting and receiving antenna 110. This implementation uses SC-FDMA or OFDMA as a multiplexing scheme.

After reception of the signals received through the transmitting and receiving antennas 110 receiver 170 checks the signals to determine whether they contain the signal addressed to the own station. If such a signal is detected, the receiver 170 demodulates and decodes the signal. Packet data included in the received signal, if any, are enclosed within. Mobile station 100 processes the packet data according to their type. For example, in the case of VoIP data of the mobile station 100 outputs the sound from the loudspeaker. In the case of electronic mail or image data of a mobile station 100 displays text or images on the display screen.

Information provide UL allocation included in the received signal, if any; the receiver 170 transmits information on the selection block 150 resources. The receiver 170 extracts a signal that should be used for measuring communication quality in downlink, from a received signal, and transmits a signal to block 180 to measure the quality of the descending line.

B is OK 180 measure the quality of downlink measures the quality of data transmission (communication) of many bands downlink on the basis of the signal, transferred from the receiver 170. Then block 180 measure the quality of downlink supplies the measurement result to the CPU 140 of the control information.

It should be noted that the mobile station 100a may be designed to have the same modular configuration as the mobile station 100.

Figure 4 is a block diagram illustrating functions of the base station. Base station 200 includes a transmitting and receiving antenna 210, a processor 220, data processor 230, pilot signal, the processor 240 of the control information, the administrator 250 resources, the scheduler 260, the transmitter 270, the receiver 280 and block 290 measure the quality of uplink communication.

The transmitting and receiving antenna 210 is the antenna for transmission and reception. The transmitting and receiving antenna 210 transmits via radio signals downlink output from transmitter 270. The transmitting and receiving antenna 210 also receives signals uplink communication transmitted by radio communication from the mobile stations 100 and 100a, and passes them to the receiver 280.

If there is packet data to be transmitted via radio to the mobile station 100, 100a, existing in the cell, the processor 220 encodes data and outputs the data. For example, when data is transmitted VoIP, e-mail data, image data or other Yes the ones, which are addressed to the mobile station 100, 100a, processor 220 encodes data and outputs the data.

The processor 230 of the pilot signal generates various types of pilot signals, which allow the mobile station 100, 100a to reproduce the packet data from the radio signals. The coding pattern is determined for each type of pilot signals.

The processor 240 of the control information generates the management information that must be transmitted by radio, encodes and transmits the information according to predefined rules. Information management, which generates the processor 240 of the control information that includes information for demodulation and decoding, such as the encoding scheme of packet data, and a radio resource used for transmission of packet data, and information provide UL allocation indicating the radio resource allocation uplink connection.

Administrator 250 resources manages radio resource downlink and uplink communication between the base station 200 and the mobile stations 100 and 100a, existing in the cell. Administrator 250 provides resources scheduler 260 and receiver 230 information about the current state of distribution radioresource. In the allocation of the uplink radio resource, the mobile station 100, 100a administrator 250 RES the owls refers to the measurement of communication quality, supplied from block 290 measure the quality of uplink communication. Administrator resources 250 preferably distributes the frequency range with good quality.

The scheduler 260 determines radioresource that should be used for packet data, the pilot signal and information management, which are addressed to each mobile station based on the information about the current state of distribution radioresource downlink supplied from the administrator 250 resources. This implementation uses OFDMA as the multiplexing scheme.

In accordance with commands from the scheduler 260, the transmitter 270 modulates and multiplexes the packet data signal, the pilot signal and the signal control information, and outputs the result to the transmitting and receiving antenna 210.

When served the received signals from the transmitting and receiving antennas 210, the receiver 280 demodulates and decodes the signal transmitted from each of the mobile stations 100 and 100a, existing in the cell, with reference to the information distribution radioresource ascending line supplied from the administrator 250 resources. Packet data included in the received signal, if any, are inside. The base station 200 transmits packet data taken on your destination computer or mobile station.

When served SRS from the receiver 280, block 290 measure the quality of uplink communication measures the communication quality of the multiple frequency bands uplink communication based on the SRS. Then block 290 measure the quality of uplink communications supplies the measurement result to the administrator 250 resources.

Figure 5 illustrates the frame structure. Figure 5 schematically depicts the structure of the frame that is transmitted and received between the mobile stations 100 and 100a and the base station 200. Each frame has a duration time of 10 MS and has many podkatov with a duration time of 1 MS.

Each podcat additional shares in the frequency domain and in time domain to control the distribution radioresource. The minimum unit (unit) for distribution on the axis of frequency is called a subcarrier, and the minimum unit (unit) for distribution on the time axis is called a symbol. The smallest unit of allocation radioresource represented by one subcarrier and one symbol is called a resource element. Thus, the first and second half of the 1-MS podagra, each of the which, therefore, has a duration of 0.5 MS, called slots, respectively. That is one podagra there are two slots.

Such radioresource are used for control channels upward communication and downward communication line and data transmission channels for uplink communication and downlink. When the signal is transmitted, guard interval, called CP (Cyclic Prefix)is inserted at the beginning of each symbol, in order to prevent interference between signals due to propagation delay. In the present description there are two types of prefixes CP (Short CP and Long CP)having different length of time.

6 illustrates the distribution channels downlink. 6 schematically depicts the structure podagra, which is transmitted through a downlink from the base station 200 to the mobile station 130 and 100a. For downlink distributed radioresource for control channels of the descending line of communication and data transmission channels on the downlink to the mobile stations.

Each control channel of the descending line is allocated a radio resource having a predefined length of the symbol at the beginning of podagra. In General, first distributed one to three characters. The frequencies of the control channels of the descending line of communication for multiple mobile stations are the Xia multiplexed. The mobile station 100, 100a detects the control channel of the descending line of communication for its own station from the set of control channels descending line, whose frequencies are multiplexed. The control channel of the descending line is used to transmit information indicating the data coding scheme included in the data channel downlink, the radio resource used for data channel downlink, and the information providing distribution UL.

Each data channel downlink is allocated a radio resource different from radioresource used for control channels of the descending line. Frequency of data transmission channels downlink for many mobile stations are multiplexed. Data channels downlink channels and control the descending line are multiplexed in time. The mobile station 100, 100a refers to the management information transmitted on the control channel of the descending line, to identify the radio resource data channel downlink for its own station. The number radioresource that should be used for channel data transmission in downlink, is variable. Cana is data downlink is used for packet data.

The above-mentioned control channel of the downward communication line can be represented as a PDCCH (physical control channel downlink), while the above data channel downlink can be represented as a PDSCH (physical shared channel downlink).

Fig.7 illustrates the distribution channels of upward communication. 7 schematically depicts the structure podagra, which is transmitted via uplink communication from the mobile stations 100 and 100A to the base station 200. For uplink communication radioresource allocated to the control channels of upward communication line, each of which is shared by multiple mobile stations, and the data channels of upward communication line, each of which uses one mobile station.

Each control channel of the ascending line is allocated radio resource predetermined frequency range, comprising one of the two limiting frequencies, or frequency ranges, located on both edges of the transmission range, the entire range of frequencies available between the mobile stations 100 and 100A and the base station 200.

In the present description for the upward communication line are provided two control channel ascending line. One channel management is of the upward communication line uses high-frequency radio resource in the slot of the first half and low-frequency radio resource in the slot of the second half (represented as a control channel ascending line i 7). Another control channel trend line communication uses low-frequency radio resource in the slot of the first half and high-frequency radio resource in the slot of the second half (represented as a channel j management ascending line 7).

One of the two control channels of upward communication line is distributed to each mobile station 100, 100A via the base station 200. The base station 200 indirectly manages the distribution of mobile stations 100 and 100A through distribution channels management descending line for downlink. More specifically, the control channels of upward communication line are distributed according to distribution channel management descending line in such a way that the mobile stations, which are distributed channel i control the descending line figure 6, uses the channel i control the ascending line of communication, a mobile station, which is distributed channel j management descending line, uses channel j control the upward communication line, and a mobile station, which is distributed channel k management descending line, uses the channel i control the ascending line of communication i.

The control channel of the ascending line is used to transmit ACK/NACK, CQI and requests distribution radioresource, etc. On each Kahn the Lu management of the ascending line is encoded is multiplexed and then transmitted control information from multiple mobile stations. Usually one control channel trend line connection allows the transmission of control information from six mobile stations. If the base station 200 has many mobile stations, the base station 200 provides protection over a wide frequency range for control channels of upward communication line, thus allowing multiple mobile stations to transmit the management information on the control channels of upward communication line.

Each data channel uplink connection is allocated a range of frequencies different from the frequencies used for control channels of upward communication line. Frequency of data transmission channels in the ascending line of communication from many mobile stations are multiplexed. The mobile station 100, 100a identifies the usable radio resource for data transmission channel uplink communication based on the information provide UL allocation received over the control channel of the descending line. Data channel uplink communication is used to transmit packet data. In addition, the data channel uplink communication may also be used to transfer control information.

the Mobile station 100, 100a determines which one of the control channel trend line of communication and data transmission channel in the ascending line of communication is suitable for use for transmission of control information on the basis of assigned or not the data transmission channel uplink communication via the base station 200. More specifically, if the data transmission channel in the ascending line of communication has been assigned, the mobile station 100, 100a uses this data channel uplink communication control information along with the packet data. On the contrary, if no data channel uplink connection has not been assigned, the mobile station 100, 100a uses the control channel of the upward communication line for transmitting control information.

Incidentally, in the ascending line, SRS, which is a broadband signal may be transmitted in addition to the signals on the control channels of upward communication line and data transmission channels uplink communication. SRS is transmitted from mobile station 100, 100a in response to the command from the base station 200. The following describes how to multiplex SRS and other signals in the ascending line of communication.

Fig illustrates an example of signals uplink communication, which includes ACK, according to the first variant implementation. Fig describes how to distribute glad resursy in case when the signal showing the ACK and SRS is multiplexed in potcake with Short CP. Podcat with Short CP includes 14 characters. Seven characters of the first half is a slot, and seven characters of the second half of the slot.

In each of the slots of the first and second half of the bands i manage ascending line four of these seven characters allocated for ACK, while the other three are allocated for RS (pilot signal). More specifically, the symbols are allocated for ACK, ACK, RS, RS, RS, ACK and ACK in order from the first character. It should be noted that a single bit is sufficient to signal the ACK/NACK and, thus, the same signal is transmitted in symbols allocated for the ACK.

Similarly, for channel i control the ascending line in each of the slots of the first and second halves of the channel j management ascending line four of these seven characters allocated for ACK, while the other three are allocated for RS. However, when one or more mobile stations transmit the SRS, the first symbol of each slot is used for transmission of SRS and is not used for sending ACK.

Broadband radio resource that is allocated for SRS, does not include the frequency range of channel i control the ascending line, but includes the frequency range of channel j management ascending line with the ides. Thus, it is preferable that the frequency range of channel i control the ascending line and one for transmitting the SRS was not consistent. This is because the increase in the number of mobile stations belonging to the base station 200 may increase the need to ensure a wider range of frequencies for channel i control the upward communication line.

In the radio resource that is distributed to the SRS, the SRS signals from multiple mobile stations can be encoded to multiplicious and then transmitted. Thus, the mobile stations 100 and 100a can transmit their signals SRS at the same time. It should be noted that the mobile station 100, 100a does not output the signal for all frequencies of the radio resource allocated for SRS, and selects part of frequency and outputs the signal. For this reason, on the basis of the transmission quality of the selected parts of the frequency, the transmission quality of other frequencies can be evaluated.

Consider the case where the mobile station 100 and 100a are in the same cell, one mobile station 100 transmits the SRS and the other mobile station 100a does not pass.

In this case, the base station 200 allocates the mobile station 100, which is supposed to transmit the SRS, the radio resource, which should be used for SRS transmission, and channel j of the control of the upward communication line as the channel the control of the upward communication line. According to this distribution of the mobile station 100 transmits SRS in the first symbol of each slot.

In order to transmit ACK in addition to the SRS in the same potcake, the mobile station 100 uses channel j management ascending line in characters other than the first symbol of each slot. However,,if the mobile station 100 has a data transmission channel in the ascending line of communication assigned to the base station 200, the mobile station 100 transmits the ACK for the data channel in the ascending line of communication, not on channel j management ascending line. In this case, the mobile station 100 also avoids using the first symbol in each slot.

On the other hand, the base station 200 allocates the channel i control the ascending line as the control channel ascending line of communication for the mobile station 100a, which is expected should not transmit SRS. Mobile station 100a uses the channel i control the upward communication line for transmitting the ACK. At this time, the mobile station 100a can use all the slots in potcake. However, if the mobile station 100a has the data transmission channel ascending line of communication assigned to the base station 200, the mobile station 100a transmits ACK for the data channel uplink communication, not on the channel i control the ascending line. In this case, the mobile station is I 100 avoids using the first symbol in each slot. The base station 200 in advance provides the mobile station 100a, a notification that the mobile station 100 is supposed to transmit the SRS.

If no mobile station does not transmit SRS in the cell, the base station 200 allocates the channel i control the ascending line of communication for a mobile station moving at low speed, and channel j of the control of the upward communication line mobile station moving at high speed. For this reason, such a mobile station moving at low speed, may transmit SRS in longer intervals, because the quality of communication with the mobile station may not often be measured.

Fig.9 illustrates an example of signals uplink communication, which includes CQI, according to the first variant implementation. Fig.9 describes how to distribute radioresource when the signal indicating the CQI and SRS is multiplexed in potcake with Short CP.

In each of the slots of the first and second half of the bands i manage ascending line five of these seven characters allocated for CQI, while the other two are allocated for RS. More specifically, the symbols are allocated for CQI, CQI, RS, CQI, RS, CQI and CQI in order from the first character. It should be noted that the CQI signal is divided and transmitted in a set of characters.

Similarly, for channel i control the rising Lin is her due, in each of the slots of the first and second half of the channel j management ascending line five of these seven characters allocated for CQI, while the other two are allocated for RS. However, when one or more mobile stations transmit the SRS, the first character is used for transmission of SRS and is not used for transmission of CQI.

As described above, in the case of ACK on Fig, channel j management ascending line is allocated mobile station, which is supposed to transmit the SRS, and the channel i control the upward communication line is allocated mobile station, which is expected should not transmit SRS. Therefore, even when the other mobile station transmits the SRS, the mobile station which does not transmit the SRS, can use all characters in potcake for CQI transmission on the control channel of the ascending line.

Figure 10 illustrates another example of signals uplink communication, which includes ACK, according to the first variant implementation. Figure 10 describes how to distribute radioresource when the signal indicating ACK and SRS is multiplexed in potcake Long CP. Podcat Long CP includes twelve characters. Six characters of the first half of the slot, and six characters of the second half of the slot.

In each of the slots of the first and second half of the s channel i control the upward communication line four of these six symbols are allocated for ACK while the other two are allocated for RS. More specifically, the symbols are allocated for ACK, ACK, RS, RS, ACK and ACK in order from the first character. All characters allocated for ACK transmitted the same signal.

Similarly, for channel i control the upward communication line, each of the slots of the first and second halves of the channel j management ascending line four of these six symbols are allocated for ACK, while the other two are allocated for RS. However, when one or more mobile stations transmit the SRS, the first character is used for transmission of SRS and is not used for sending ACK.

As described above, in the case of Short CP on Fig, channel j management ascending line is allocated mobile station, which is supposed to transmit the SRS, and the channel i control the upward communication line is allocated mobile station, which is expected should not transmit SRS. Therefore, even when the other mobile station transmits the SRS, the mobile station which does not transmit the SRS, can use all characters in potcake for ACK transmission on the control channel of the ascending line.

11 illustrates another example of signals uplink communication, which includes CQI, according to the first variant implementation. 11 describes how to allocate resources when the signal, the CQE practice showing and SRS, is multiplexed in potcake Long CP.

In each of the slots of the first and second half of the bands i manage ascending line five of these six symbols are allocated for CQI, while the other symbol is allocated for RS. More specifically, the symbols are allocated for CQI, CQI, RS, CQI, CQI and CQI in order from the first character. It should be noted that the CQI signal is divided and transmitted in a set of characters.

Similarly, for channel i control the upward communication line, each of the slots of the first and second half of the channel j management ascending line five of these six symbols are allocated for CQI, while the other symbol is allocated for RS. However, when one or more mobile stations transmit the SRS, the first character is used for transmission of SRS and is not used for transmission of CQI.

As described above, in the case of Short CP figure 9, the channel j management ascending line is allocated mobile station, which is supposed to transmit the SRS, and the channel i control uplink communication is distributed mobile station, which is expected should not transmit SRS. Therefore, even when the other mobile station transmits the SRS, the mobile station which does not transmit the SRS, can use all characters in potcake for CQI transmission on the control channel of the ascending line of the script.

Fig-11 describe how the transmitted ACK or CQI as an example of signal uplink communication. Other types of control information can be transmitted in the same way. In addition, not only one type of control information, but also some types of control information can be transmitted in the same potcake. For example, ACK and CQI may be transmitted in the same potcake.

The following describes how to manage the distribution radioresource between the mobile stations 100 and 100a and the base station 200. The following examples are cases of SRS multiplexing and signal on the data channel in the ascending line of communication and SRS multiplexing and signal on the control channel of the ascending line.

Fig is a sequence chart illustrating the distribution control when the SRS and data uplink communication overlap. The sequence on Fig will be described step by step. This explanation focuses on the uplink communication from the mobile station 100 to the base station 200.

(Step S11), the base station 200 detects the need to measure the quality of communication uplink communication from the mobile station 100 to the base station 200. Then the base station 200 allocates the mobile station 100, the radio resource, which should be used for SRS transmission, and sets and what tervala transmission. Then the base station 200 transmits the information distribution control channel of the descending line.

(Step S12), the Mobile station 100 transmits the SRS to the radio resource allocated at step S11. The base station 200 measures the communication quality of the uplink communication based on the SRS received from the mobile station 100.

(Step S13) After the mobile station 100 transmits the SRS in the transmission intervals set at step S11, and, accordingly, the base station 200 measures the communication quality based on the received SRS.

(Step S14), the Mobile station 100 detects a request to send packet data to the base station 200. Then, the mobile station 100 sends a request for distribution radioresource control channel ascending line.

(Step S15), the base station 200 allocates a data transmission channel uplink, the mobile station 100 in response to the allocation request accepted on the step S14. At this time, the base station 200 selects a range of frequencies that should be used, based on the results of measurements made in steps S12 and S13. Then the base station 200 transmits the information providing distribution UL control channel of the descending line.

(Step S16), the Mobile station 100 transmits packet data on the data channel uplink communication, distributed at the step S15.

(Step S17), the base station 200 re-distributes the data channel uplink, the mobile station 100 after receiving the packet data from the mobile station 100, and then transmits the information providing distribution UL control channel of the descending line. After that, the transmission of packet data from the mobile station 100 and the distribution channel data uplink communication base station 200 are repeated until the packet data transfer is completed.

(Step 318) the base station 200 detects overlapping (overlapping) the transmission of SRS and packet data from the mobile station 100 in the distribution channel data in the ascending line of communication, that is, detects that the SRS and batch data must be transferred in the same potcake. Then the base station 200 sends a report overlay with transmitting SRS, together with information providing the distribution of the UL control channel of the descending line.

(Step S19)The mobile station 100 transmits the SRS to the radio resource allocated at step S11. The base station 200 measures the communication quality of the uplink communication based on the SRS received from the mobile station 100.

(Step S20), the Mobile station 100 transmits packet data on the data channel uplink communication, distributed at the step S18, in characters other than those which the ies are used to transmit the SRS.

As described above, the mobile station 100 periodically transmits SRS in response to a command from the base station 200, and accordingly, the base station 200 measures the communication quality of the uplink communication based on the received SRS. Then after receiving a request for allocation of a data channel in uplink communication, the base station 200 selects a range of frequencies that must be distributed on the basis of the results of measurement of the communication quality.

When SRS and the signal on the data channel in the ascending line of communication must be multiplexed, the mobile station 100 transmits packet data to the data transmission channel uplink connection for packet data does not overlap with the radio resource for transmission of the SRS.

Fig is a sequence chart illustrating the distribution control in the case where SRS and ACK are superimposed. The sequence on Fig will be described step by step.

The following explanation focuses on the uplink communication from the mobile station 100 to the base station 200.

(Step S21), the base station 200 detects the need to measure the quality of communication uplink communication from the mobile station 100 to the base station 200. Then the base station 200 allocates the mobile station 100, the radio resource, which should be used for SRS transmission, ustanavli is that the intervals of transmission and then transmits the information distribution control channel of the descending line.

(Step S22), the Mobile station 100 transmits the SRS to the radio resource allocated at the step S21, and the base station 200 measures the communication quality of the uplink communication based on the SRS received from the mobile station 100.

(Step S23) After that, the mobile station 100 transmits the SRS in the transmission intervals set at step S21, and, accordingly, the base station 200 measures the communication quality based on the received SRS.

(Step S24), the base station 200 receives the packet data addressed to the mobile station 100. Then the base station 200 sends a report of the radio resource used for data channel downlink control channel of the downward communication line, and transmits packet data on the data channel downlink.

(Step S25) In response to the packet data received at the step S24, the mobile station 100 transmits the ACK or NACK control channel ascending line. More specifically, the mobile station 100 transmits the ACK, if the demodulation and decoding packet data completes successfully. On the contrary, the mobile station 100 transmits a NACK if the demodulation and decoding are not successful.

(Step S26), the base station 200 sends a report of the radio resource used for data channel downlink, the control channel of the downward communication line, and transmits the packet the data on the data channel downlink. Packet data that must be passed here are the packet data that must be sent after the ACK will be made at step S25. If a NACK is received, the packet data transmitted last time is transmitted again. After this reply the ACK/NACK from the mobile station 100 and the transfer of packet data from the base station 200 are repeated until the packet data transfer will not be completed.

(Step S27) When the distribution of the data channel downlink, the base station 200 detects an overlapping transmission of SRS and ACK/NACK from the mobile station 100, that is, detects that the SRS and ACK/NACK needs to be transmitted in the same potcake. Then the base station 200 allocates different control channels of upward communication line mobile station 100 and other mobile stations, which must not transmit SRS. The distribution of the data channels of upward communication line is changed by changing the allocation of control channels of the descending line. Then the base station 200 sends a report of the radio resource used for data channel downlink, the control channel of the downward communication line and transmits packet data on the data channel downlink.

(Step S28), the Mobile station 100 transmits the SRS for the resource, distributed at the step S21, and the base station 200 measures the communication quality of the uplink communication based on the SRS received from the mobile station 100.

(Step S29) In response to packet data at step S27, the mobile station 100 transmits the ACK or NACK control channel ascending line in characters other than those used for SRS transmission.

As described above, in response to a command from the base station 200, the mobile station 100 periodically transmits the SRS, and, accordingly, the base station 200 measures the communication quality of the uplink communication based on the received SRS. When receiving a packet data addressed to the mobile station 100, the base station 200 transmits packet data on the data channel downlink. After receiving the packet data, the mobile station 100 transmits a response ACK/NACK.

If SRS and ACK/NACK should be multiplexed, then the base station 200 allocates different control channels of upward communication line mobile station 100 and other mobile stations, which must not transmit SRS. The mobile station 130 transmits ACK/NACK to the control channel of the upward communication line for transmitting ACK/NACK does not overlap with the source radio to transmit SRS.

The above description describes the case where one and the same mobile station transmits the PA is to maintain the data or information management, and SRS. The same control can be the case when different mobile stations transmit them.

In the above communication system, one of the two control channels of upward communication line can be used without interference in relation to the SRS, even in podagra, including the transmission of the SRS. Therefore, SRS and the signal control information can be multiplexed in such a way as not to cause deterioration in communication quality. In addition, through the use of SRS, which is received in the slot of the first half, and SRS, which is received in the slot of the second half, the base station can measure the quality of a wide range of frequencies.

(The second variant implementation)

The second variant implementation is described below in detail with reference to the accompanying drawings. This section focuses on differences from the above-mentioned first variant implementation, and will omit the explanation of the same features. The communication system according to the second variant implementation uses one podcat, and not one slot as the transmission interval of the pair of the two signals SRS.

The communication system according to the second variant of implementation can be realized by the same configuration as the first embodiment. Mobile station and base station according to the second variant implementation of m which may be implemented by the same configuration of modules as the mobile station 100 and base station 200 in figure 3 and 4, as in the first embodiment, respectively. However, the second variant implementation transmits and receives SRS and measures the communication quality in good time from the first variant implementation. The following description of the second variant implementation uses the same reference position of the mobile station and the base station as the first version of the implementation.

Fig illustrates an example of signals uplink communication, which includes ACK according to the second variant of implementation. Fig illustrates how to allocate radioresource when the signal indicating ACK and SRS is multiplexed in two consecutive pocketrak with Short CP.

In each slot of the channel i control the upward communication line four of these seven characters allocated for ACK, while the other three symbols are allocated for RS. More specifically, the symbols are allocated for ACK, ACK, RS, RS, RS, ACK and ACK in order from the first character. However, when one or more mobile stations transmit the SRS, the first character of the second podagra is used for transmission of SRS and is not used for sending ACK.

Similarly, for channel i control the upward link in each slot of channel j management ascending line four of these seven characters allocated for ACK, while the other three are allocated for RS. However, when the on or more mobile stations transmit SRS, the first character of the first podagra is used for transmission of SRS and is not used for sending ACK.

In the first symbol of the first podagra broadband radio resource that is allocated for SRS, does not include the frequency range of channel i control the ascending line, but includes a channel resource j management ascending line. In the first symbol of the second podagra broadband radio resource that is allocated for SRS includes the frequency range of channel i control the ascending line, but does not include the channel resource j management ascending line.

The mobile station, which is supposed to transmit SRS, distributed channel j management ascending line of the first podagra and the channel i control the ascending line of the second podagra. On the other hand, mobile station, which is expected should not transmit SRS, distributed channel i control the ascending line of the first podagra and channel j of the control of the ascending line of the second podagra. Therefore, a mobile station that does not transmit the SRS, but transmits the ACK control channel ascending line, can use all characters in podkraj, even when the other mobile station transmits the SRS. In addition, the base station 200 can measure the communication quality on the basis of C the signals SRS, taken in the first two characters of the serial podkatov.

Fig illustrates an example of signals uplink communication, which includes CQI, according to the second variant of implementation. Fig illustrates an example of how to distribute radioresource when the signal indicating the CQI and SRS is multiplexed in two consecutive pocketrak with Short CP.

In each slot of the channel i control the upward communication line five of the seven symbols are allocated for CQI, while the other two are allocated for RS. More specifically, the symbols are allocated for CQI,CQI RS, CQI, RS, CQI and CQI in order from the first character. However, when one or more mobile stations transmit the SRS, the first character of the second podagra is used for transmission of SRS and is not used for transmission of CQI.

Similarly, for channel i control the ascending line, in each slot of channel j management ascending line five of these seven characters allocated for CQI, while the other two are allocated for RS. However, when one or more mobile stations transmit the SRS, the first character of the first podagra is used for transmission of SRS and is not used for transmission of CQI.

As described for example ACK on Fig, mobile station, which is supposed to transmit SRS, distributed channel j management ascending line St is ze first podagra and the channel i control the ascending line of the second podagra. On the other hand, mobile station, which is expected should not transmit SRS, distributed channel i control the ascending line of the first podagra and channel j of the control of the ascending line of the second podagra. Therefore, a mobile station that does not transmit the SRS, but transmits CQI control channel ascending line, can use all characters in podkraj, even when the other mobile station transmits the SRS. Then the base station 200 can measure the communication quality on the basis of signals SRS taken in the first two characters of the serial podkatov.

Fig and 15 illustrate how transmitted ACK or CQI as an example of signal uplink communication. The same technique can be used to transmit other types of information management. In addition, not only one type of control information, but also various types of control information can be transmitted in the same potcake. For example, ACK and CQI may be transmitted in the same potcake. In addition, Fig and 15 illustrate an example of a Short CP. However, the Long CP can be used as described in the first embodiment.

This communication system can provide the same results as the results of the first variant implementation. In addition, the communication system according to the second variant implementation can p is dawlati the reduction in the number of signals, which should multiplicious in time with SRS control channel ascending line.

(A third option exercise)

The third variant of the implementation are described in detail below with reference to the accompanying drawings. This section focuses on differences from the above-mentioned first variant implementation, and will omit the explanation of the same features. The communication system according to the third variant of implementation, allows the mobile station to perform transmission with antenna diversity, i.e. to perform radio communication with multiple antennas.

The communication system according to the third variant of implementation can be realized by the same configuration as in the first embodiment according to Figure 2, except that the mobile station and the base station in the third embodiment perform antenna diversity. The mobile station and the base station in the third embodiment are given reference position 100b and 200a, respectively.

Fig is a block diagram illustrating functions of a mobile station according to the third variant of implementation. Mobile station 100b includes a transmitting and receiving antenna 110 and 110b, the processor 120 of the data processor 330 pilot signal, the processor 140 of the information control unit 150b choice of resource, the transmitter 160b, the receiver 170b and unit 180 dimension to the quality of the descending line. The processor 120 of the data processor 130 pilot signal, the processor 140 of management information and the block 180 measure the quality of downlink have the same functions of the respective components as in the first embodiment, figure 3.

Transmitting and receiving antenna 110 and 110b are antennas for transmission and reception. Each transmitting and receiving antenna 110, 110b transmits signals uplink communication, the output from the transmitter 160b via radio, to the base station 200a. In addition, the transmitting and receiving antenna 110, 110b receives signals downlink transmitted by radio from the base station 200a and transmit signals to the receiver 170b. During transmission, the transmitter 160b selects one of the transmitting and receiving antennas 110 and 110b.

The block 150b select resource manages uplink radio resource that is available to the mobile station 100b. In addition, the block 150b selection of resource controls the switching between the transmitting and receiving antennas 110 and 110b for use in the broadcast. The block 150b select resource provides transmitter 160b information regarding the current state of the distribution radioresource and select which antenna to use.

The transmitter 160b identifies radioresource that should be used for transmitting pilot data pilot signal is Ala and information management on the basis of the information provided by the block 150b choice of resource. The transmitter 160b also selects the transmitting and receiving antenna, which must be used for each transmission, on the basis of information provided by the block 150b choice of resource. Then the transmitter 160b modulates and multiplexes the signals, and outputs the result to the selected transmitting and receiving antenna.

When receiving signals through the transmitting and receiving antennas 110 and 110b receiver 170b selects the signal with the highest reception quality, and then demodulates and decodes the signal addressed to the own station from the selected received signal. Packet data included in the received signal, if any, are inside.

The receiver 170b transmits information provide UL allocation unit 150b select the resource that is included in the received signal, if it exists. If the management information to instruct the switching of the antenna is included in the received signal, the receiver 170b transmits the information to the block 150b choice of resource. In addition, the receiver 170b issues unit 180 measure the quality of downlink signal, which should be used to measure the quality of communication downlink in relation to the received signal.

The control method for switching the antenna unit 150b select resource includes management with open-circuited and the management closed loop. When operating with open-circuited unit 150b of resource selection switches between transmitting and receiving antennas 110 and 110b, as planned. For example, the block 150b select resource periodically switches between transmitting and receiving antennas 110 and 110b.

When running closed loop, on the other hand, the block 150b of resource selection switches between transmitting and receiving antennas 110 and 110b in response to a command from the base station 200a. The base station 200a instructs which antenna to use based on, for example, the transmission quality of the signals received from the respective transmitting and receiving antennas 110 and 110b.

Control method that should be adopted in advance is set in the block 150b choice of resource. This implementation uses a running closed loop.

The base station 200a according to the third variant of implementation can be implemented in the same module configuration, as in the base station 200 of the first version of the implementation in figure 4, except that the communication quality is measured each transmitting and receiving antennas 110 and 110b provided in the mobile station 100b.

Fig illustrates an example of signals uplink communication, which includes ACK, according to the third variant of implementation. Fig illustrates how to allocate radiora the escarpment in the case when the signal indicating ACK and SRS is multiplexed in potcake with Short CP. The upper signals are signals that are transmitted from the transmitting and receiving antenna 110 to the base station 200a, while the lower signals are signals that are transmitted from the transmitting and receiving antenna 110b to the base station 200a. It should be noted that Fig not illustrate the signals that are transmitted from other mobile stations.

As in the aforementioned first embodiment, the mobile station 100b, which is supposed to transmit SRS, distributed channel j management ascending line. Now assume that the mobile station 100b selects the transmitting and receiving antenna 110 to the radio. Then the mobile station 110b transmits the ACK signals and RS channel j management ascending line from the transmitting and receiving antenna 110. Mobile station 110b transmits SRS in the beginning of each slot.

Thus, one of the two signals SRS is transmitted from the transmitting and receiving antenna 110, and the other signal is transmitted from the transmitting and receiving antenna 110b. Thus, the mobile station 100b is intended for SRS transmission from the transmitting and receiving antenna 110b even during ACK transmission from the transmitting and receiving antenna 110. This allows the base station 200a to measure the quality of light and how the transmission, and receiving antennas 100 and 100b.

Fig.18 illustrates an example of signals uplink communication, which includes CQI, according to the third variant of implementation. Fig illustrates how to allocate radioresource when the signal indicating the CQI and SRS is multiplexed in potcake with Short CP.

Mobile station 100b transmits the CQI and the signal RS for channel j management ascending line from the transmitting and receiving antenna 110. Mobile station 100b transmits SRS in the beginning of each slot. Thus, one of the two signals SRS is transmitted from the transmitting and receiving antennas 110, while the other signal is transmitted from the transmitting and receiving antenna 110b. Thus, the mobile station 100b is intended for SRS transmission from the transmitting and receiving antenna 110b even during the CQI transmission from the transmitting and receiving antenna 110. This allows the base station 200a to measure the quality of communication as transmitting and receiving antennas 110 and 110b.

Meanwhile, only for the mobile station 100b to select the antenna, which must be used, it is not necessary to measure the transmission quality over a wide frequency range. Additionally, if the mobile station 100b has no packet data for transmission on the uplink communication within a predetermined period of time, the base station is I 200a does not need to measure the quality of transmission frequencies, which can be used for data transmission channel uplink communication. Therefore, there is no packet data to be transmitted in uplink communication, the mobile station 100b transmits the SRS transmission frequency different from the frequency range of the control channel of the ascending line.

Fig illustrates another example of signals uplink communication, which includes ACK, according to the third variant of implementation. Fig illustrates how to allocate radioresource when the signal indicating ACK and SRS is multiplexed in potcake with Short CP and the mobile station 100b has no packet data to send.

Mobile station 100b transmits the ACK signals and RS channel j management ascending line from the transmitting and receiving antenna 110. Mobile station 100b transmits SRS only with the frequency range of channel j control rising line at the beginning of each slot. Thus, the SRS transmission is performed from the transmitting and receiving antennas 110 in one of these two slots and from the transmitting and receiving antenna 110b in a different slot.

This prevents the base station 200a from receiving information that should be used to select the range of frequencies that must be allocated to the data channel uplink communication, but allows the base when Anzhi 200a to get information, which should be used by the mobile station 100b to select the antenna that should be used. To skip the SRS transmission using a frequency different from the frequency range of the control channel of the ascending line, the mobile station 100b in advance provides the base station 200a notification that the mobile station 100b has no packet data to send.

Fig illustrates another example of signals uplink communication, which includes CQI, according to the third variant of implementation. Fig illustrates how to allocate radioresource when the signal indicating the CQI and SRS is multiplexed in potcake with Short CP and the mobile station 100b has no packet data to send.

Mobile station 100b transmits the CQI and the signal RS for channel j management ascending line from the transmitting and receiving antenna 110. Mobile station 100b transmits SRS only with the frequency range of channel j control rising line at the beginning of each slot. Thus, the SRS transmission is done from the transmitting and receiving antennas 110 in one of these two slots and from the transmitting and receiving antenna 110b in a different slot.

This prevents the base station 200a from receiving information that should be used to select the range of frequencies that must be distributed to the Nala data transfer for uplink communications, but allows the base station 200a to get information that should be used by the mobile station 100b to select the antenna that should be used.

Fig-20 illustrate how transmitted ACK or CQI as an example of signal uplink communication and other types of control information can be transmitted in the same way. In addition, not only one type of control information, but also some types of control information can be transmitted in the same potcake. For example, ACK and CQI may be transmitted in the same potcake. In addition, although Fig-20 illustrate an example of a Short CP, Long CP can be used as described in the first embodiment. Additionally, the SRS may be transmitted in the first two characters of the serial podkatov, as described in the second embodiment.

This communication system can provide the same results as the results of the first variant implementation. Additionally, communication system according to the third variant of implementation of the results of measuring the communication quality on the basis of signals from the SRS can be used to select the antenna when the antenna diversity. Additionally, when the mobile station has no packet data for transmission, the frequency range may be reduced for SRS transmission, thereby reducing load is about measuring communication quality to the base station.

Although this implementation uses the first symbol of each slot for transmitting the SRS, the predefined symbol, except the first, can be used for SRS transmission. Additionally, although this implementation passes a couple of SRS signals in two consecutive slots or podkraj, signals SRS may be transmitted in separate slots or pocketrak. Additionally, this implementation uses two limit (boundary) frequency frequency range available between the mobile station and the base station, for the two control channels of upward communication line may be used predefined frequency range except for the marginal frequencies.

The foregoing description is considered as the only illustration of the principles of the present invention. Additionally, since numerous modifications and changes will be obvious to a person skilled in the art, it is not desirable to limit the invention to the exact construction and applications shown and described, and accordingly, all suitable modifications and equivalents may be regarded as falling within the scope of the invention in the appended claims and their equivalents.
