The technical field to which the invention relates

The present invention relates to a transmission device, receiving device and method of data transmission and, more specifically, to the transmission device capable of performing the transmission and reception of data using a variety of frequencies, the pickup device and method of data transfer.

Prior art

Currently in the field of mobile communication systems of the communication system during the use CDMA (multiple access code division multiplexing) as the multiple access scheme. On the other hand, research in relation to mobile communication systems of the next generation was very active, focuses on faster wireless data. 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, called 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 multiple schemes�access. Such mobile communication system planning data transmission on uplink from the mobile station to the base station as follows.

When the mobile station has a management information and other data for transmission, the base station performs dynamic allocation of radio resources in the frequency domain and time domain for channel data transmission in uplink. Then the base station provides the mobile station, the result of the allocation of radio resources. According to this result, the mobile station transmits the control information and other data as distributed on the frequency and distributed time intervals.

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

Incidentally, the base station preferably distributes the frequency range with the best quality of communication on uplink for the data channel in uplink from the available bandwidth between the base station and mobile station. Therefore, before resources are allocated for channel data transmission in uplink, the mobile station needs to transmit to a base station of a broadband pilot signal (SRS: Sounding Reference Signal), which is used to measure the quality of communication uplink. In this case, the problem arises of how to multiplex information management and SRS, when the same or different mobile stations transmit simultaneously. To resolve this issue, we propose the following scheme multiplexing (for example, see non-patent Literature 3).

Fig.21 illustrates an example of uplink signals, including SRS. In this example according to Fig.21 ACK is transmitted as control information with two ranges of frequencies as channels i and j control a rising line. A mobile station is allowed to use one of these channels i and j control a rising line of communication to convey information management. For each control channel whether ascending�Oia communications signal, specifies the management information, and the pilot signal (RS (Reference Signal) are scheduled in a predetermined order. However, in a pre-defined period of the time units of all the frequency bands are reserved as radio resources for transmission of SRS. When the transmission of the SRS, the mobile station uses the reserved resource in a predetermined period of the time unit.

The problems that must be solved by the invention

However, the scheme of multiplexing in time used in non-patent Literature 3, does not allow to transmit information management at the same time as a broadband signal that should be used to measure the quality of communication. Therefore, as compared to the case not the broadband signal multiplexing and signal control information, this scheme provides less radio resources available in each period of time units for each channel uplink. This causes problems�, what is the quality of reception of the signal indicating information management, deteriorating in the pickup device (corresponding to the above-described base station on the uplink), and that the number of transmission devices (corresponding to the above described mobile station on the uplink), 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 a data transfer method, which can prevent the 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 predetermined frequency band, performed at the same time.

A means for solving problems

To solve the aforementioned problem, the present invention provides a transfer device, illustrated in Fig.1. The transmission device 1 is able to perform data transmission at the first frequency and data transmission at the second frequency. The transmission device 1 includes a transmitter 1a, which transmits a signal that should be used by the transmission device 2 for measuring the quality of communication in the predetermined part of the first time period in the range of frequencies, which has a wider p�low frequencies, than the one that is used for data transmission, and does not include the first frequency, and transmits the signal in the predetermined part of the second time period occurring after the first period of time, in the frequency range, which has a wider frequency band than that used for data transmission, and includes a second frequency.

With the device 1 of the transmission signal which should be used to measure the quality of communication, is transmitted in the predetermined part of the first time period in the range of frequencies that has a wider bandwidth than that of the data transmission, and includes the first frequency. Then, the signal that should be used to measure the quality of communication, is transmitted in the predetermined part of the second time period occurring after the first period of time, in the frequency range, which has a wider bandwidth than that of the data transmission, and includes a second frequency.

Additionally, in order to solve the aforementioned problems, provides a pickup device, illustrated in Fig.1. The 2 reception device is intended for connection with the transmission device 1, which is able to perform data transmission at the first frequency and data transmission at the second frequency. The device 2 admission includes unit 2a of the measurement of quality that is measurable�assured the quality of communication with the transmission device 1 on the basis of the signal transferred to the predetermined part of the first time period in the range of frequencies, which has a wider frequency band than that used for data transmission, and does not include the first frequency, and on the basis of the signal transmitted in the predetermined part of the second time period occurring after the first period of time, in the frequency range, which has a wider frequency band than that used for data transmission, and includes a second frequency.

Such a device 2 reception can measure the quality of communication with the transmission device 1 on the basis of the signal transmitted in the predetermined part of the first period of time, in the frequency range, which has a wider bandwidth than that of the data transmission, and includes the first frequency, and the signal transmitted in the predetermined part of the second time period occurring after the first period of time, in the frequency range, which has a wider bandwidth than that of the data transmission, and includes a 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 �of Ascot, which includes a second frequency. Therefore, there is a range of frequencies without interference of the 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 starts with an overview of options for implementation, which will be discussed in the present description, and then moves on to the details of these embodiments.

Fig.1 illustrates an embodiment of review. The communication system of Fig.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 a mobile station of a mobile communication system. The transmission device 1 includes a transmitter 1a, which transmits to the device 2 reception signal, which should be used to measure the quality of radio communications from the transmission device 1 to device 2 admission.

In more detail,the transmitter 1a transmits a broadband signal, which occupies a wider frequency range than the one that is used for transmitting data, in the predetermined 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 the predetermined part of the second time period occurring after the first time period in the range of frequencies which includes the second frequency.

The 2 reception device is a data communication device, which receives data via radio from the transmission device 1. The 2 reception device, for example, is equivalent to a base station of a mobile communication system. The pickup device 2 includes unit 2a of the measurement quality. Unit 2a of the measurement quality measures the quality of radio communication from the transmission device 1 to device 2 admission on the basis of the broadband signal received from the transmission device 1 in the first and second time periods. The measured communication quality can be used as an index to select a range of frequencies, 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 band which does not include the first frequency in the predetermined part of the first time period, and uses the frequency range that is not on�involves a second frequency in the predetermined part of the second time period, for transmission of the wideband signal. Then, block 2a quality measurement unit 2 measures the reception quality of the radio communication from the transmission device 1 to device 2 admission on the basis of the broadband signal received in the first and second time periods.

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

Therefore, this technique makes it possible to prevent deterioration in communication quality due to the reduction in time available to transmit and receive data. Additionally, the device 2 can use a broadband signal, adopted in the first and second time periods which allow to measure the quality of a wide range of frequencies.

(The first implementation option)

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

<> Fig.2 illustrates a system configuration according to the embodiment of implementation. A mobile communication system, according to the embodiment of the implementation, is the radio data system in which packet data are transmitted. The mobile communication system of Fig.2 includes a mobile station 100 and 100a and the base station 200.

Mobile stations 100 and 100a, for example, are mobile phones. Being in the communication range (cell) of the base station, the mobile stations 100 and 100a capable of performing radio communication with a base station and to transmit and receive packet data from aillustration computer or another mobile station using the base station. Packet data, the mobile stations 100 and 100a send and receive, include VoIP data (Minutes "speech on the Internet), email 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 this is appropriate. After receiving the request on the RDS (radio) from a 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.

Fig.3 is a block diagram, illustrating the functions of a mobile station according to the first embodiment of the. The mobile station 100 includes a transmitting and receiving antenna 110, a data processor 120, processor 130, the pilot signal, the processor 140 information management unit 150 selections, the transmitter 160, the receiver block 170 and 180 measure the quality of the downlink.

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

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

The processor 140 of the control information generates the management information which needs to be transmitted via radio, and encodes and outputs the information according to the prescribed rules. The management information generated by the processor 140 of the control information includes ACK/NACK, which is a response to the packet data from the base station, the CQI, which is the measurement (measure) the quality of communication in the downlink, the radio resources allocation request uplink, etc. More specifically, when it is measuring the quality of communication in the downlink from the block 180 measure the quality of the downlink, the processor 140 of the control information generates CQI.

Block 150 selections manages radio resources uplink available to 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, the distributed base station 200. In addition, the block 150 provides resources transmitter 160 information on the allocation of radio resources.

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

After reception of the received signals by using 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 inside. The mobile station 100 processes the packet data according to their type. For example, in the case of data VoIP mobile station 100 outputs the sounds from the loudspeaker. In the case of electronic mail or image data of a mobile station 100 displays the text or image on the display screen.

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

�Locke 180 measuring the quality downlink measures the quality of data transmission (communication) of a plurality of frequency bands downlink on the basis of the signal transmitted from the receiver 170. Then the block 180 measuring the quality downlink sends a 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.

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

The transmitting and receiving antenna 210 is an antenna for transmission and reception. The transmitting and receiving antenna 210 transmits via radio signals downlink output from the transmitter 270. The transmitting and receiving antenna 210 also receives the uplink signals transmitted by radio communication from the mobile stations 100 and 100a, and transmits 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, email data, image data or other given�s, which are addressed to the mobile station 100, 100a, processor 220 encodes data and outputs the data.

The processor 230 to the pilot signal generates various types of pilot signals that allow a 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 management information generates the management information which needs to be transmitted via radio, and encodes and outputs the information according to predefined rules. The management information generated by the processor 240 of management information includes information for demodulation and decoding, such as the encoding scheme of the packet data and the radio resource used for transmission of packet data, and information provide UL allocation indicating the allocation of the uplink radio resource connection.

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

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

In accordance with commands from the scheduler 260, transmitter 270 modulates and multiplexes the packet data signal, the pilot signal and the signal control information, and outputs the result to 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 allocation of radio resources uplink 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 the destination computer or mobile station.

p> If the received signal includes information management, requesting allocation of a radio resource, the receiver 280 transmits this information to the administrator 250 resources. If the received signal includes SRS, the receiver 280 transmits the SRS to the block 290 measuring the quality uplink.

When served SRS from the receiver 280, block 290 measuring the quality uplink measures the communication quality of the plurality of frequency bands uplink on the basis of SRS. Then the block 290 measuring the quality uplink sends a measurement result to the administrator 250 resources.

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

Each podcat additionally divided in the frequency domain and time domain to control the distribution of radio resources. The minimum unit (unit) for distribution on the frequency axis is called a subcarrier, and the minimum unit (unit) for distribution on the time axis is called a symbol. The smallest unit of allocation of radio resources, represented by one subcarrier and one symbol is called a resource element. The�them, the first and second half of the 1-MS podagra, each of 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 and downlink. When the signal is transmitted, guard interval, called CP (Cyclic Prefix) is inserted at the start of each symbol, in order to prevent interference between signals due to propagation delays. In the present description are two types of prefixes CP (Short CP and Long CP) having a different length of time.

Fig.6 illustrates the channel allocation downlink. Fig.6 schematically shows the structure podagra, which is transmitted in the downlink from the base station 200 to the mobile station 130 and 100a. For downlink distributed radioresource for control channels of a descending line of communication and data transmission channels in the downlink to the mobile stations.

Each control channel of the descending line is allocated a radio resource having a predetermined symbol length in early podagra. Overall, first distributed one to three characters. The frequencies of the control channels of the down�Dasha a communication line to a plurality of mobile stations are multiplexed. The mobile station 100, 100a detects the downlink control channel with a link to your own station of the plurality of downlink control channels of the communication line, whose frequencies are multiplexed. The downlink control channel of the communication line being used to transmit information indicating the coding scheme of the data included in the data channel downlink, the radio resource used for data transmission channel downlink, and provide information distribution UL.

Each data channel downlink is allocated radio resource different from the radio resources used for the downlink control channels. The frequency of transmitting downlink data to a plurality of mobile stations are multiplexed. The channels of transmission of downlink data and downlink control channels of the communication line are multiplexed in time. The mobile station 100, 100a refers to the management information is transmitted on the control channel of the downward line, to identify the radio resource of the transmission channel downlink data to the own station. The number of radio resources that should be used for channel data transmission in the downlink, is variable. Kang�l data downlink is used to transmit packet data.

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

Fig.7 illustrates the channel allocation uplink. Fig.7 schematically shows the structure podagra transmitted in uplink from the mobile stations 100 and 100a to the base station 200. For uplink radioresource are allocated to the control channels of the downward communication line, each of which is shared across multiple mobile stations, and the data channels uplink, each one of which is used by the mobile station.

Each control channel of the ascending line is distributed radio resource predetermined range of frequencies, including one of the two limiting frequencies or ranges of frequencies located at both edges of the transmission range of all range of frequencies available between the mobile stations 100 and 100a and the base station 200.

In the present description, for uplink are provided two control channels of upward communication line. One channel control�of 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 in the ascending line i on Fig.7). Another control channel ascending line 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 control a rising line in Fig.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 control the downward communication line for downlink. More specifically, the control channels of upward communication line are distributed according to the distribution of the control channels of the descending line in such a way that the mobile station, which is distributed channel i control the descending line in Fig.6 uses channel i control a rising line of communication, a mobile station, which is distributed channel j management descending line, uses channel j control a rising line of communication, and the mobile station, which is distributed channel k management descending line, uses channel i control a rising line of communication i.

The control channel of upward communication line is used to transmit ACK/NACK, CQI and asks for the allocation of radio resources, etc.) of each channel �of the Board of the ascending line is encoded, multiplexed and then transmitted management information from a plurality of mobile stations. Usually, one control channel in the ascending line connection allows you to transfer control information from six mobile stations. If the base station 200 has a lot of mobile stations, the base station 200 provides protection over a wide frequency range for control channels of upward communication line, thus allowing a number of mobile stations to transmit the control information on the control channels of upward communication line.

Each data channel uplink is allocated a range of frequencies different from the frequencies used for control channels in the ascending line. The frequency of data transmission channels on the uplink from a plurality of mobile stations are multiplexed. The mobile station 100, 100a identifies the usable radio resource for data transmission channel uplink based on the information provide UL allocation adopted by the downward control channel of the communication line. The data channel uplink is used to transmit packet data. In addition, the data channel uplink may also be used to transmit control information.

Incidentally, uplink, 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 channel uplink. 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 on the uplink connection.

Fig.8 illustrates an example of uplink signals, including ACK, according to the first embodiment of the. Fig.8 describes how to distribute glad�resursy in case when the signal instituting ACK and SRS is multiplexed in potcake Short CP. Podcat Short CP includes 14 characters. The seven symbols of the first half of the slot, and also seven characters of the second half of the slot.

In each of the slots of the first and second half of the channel i control a rising line four of these seven characters allocated for ACK, while the other three are allocated for RS (pilot tone). 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 ACK.

Similarly, for channel i control a rising line in each of the slots of the first and second halves of the channel j control a rising 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 SRS, the first symbol of each slot is used for transmission of SRS and is not used for transmission of ACK.

Broadband radio resource that is allocated for SRS, does not include the frequency range of channel i control a rising line, but includes the frequency range of channel j control a rising line with�yahzee. Thus, preferably, the frequency range of channel i control a rising line and one for the transmission of 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 a rising line.

In the radio resource allocated for SRS, the SRS signals from multiple mobile stations can be encoded, 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 outputs signals 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 exist in the same cell, and one mobile station 100 transmits the SRS and the other mobile station 100a transmits.

In this case, the base station 200 allocates the mobile station 100, which is supposed to transmit the SRS radio resource, which should be used for SRS transmission, and channel j of management ascending line as Kang�La control a rising line. According to this allocation, the mobile station 100 transmits SRS in the first symbol of each slot.

To transmit ACK in addition to SRS in the same potcake, the mobile station 100 uses the control channel j a rising line in characters other than the first symbol of each slot. However,,if the mobile station 100 has a data transmission channel for uplink that is assigned to base station 200, the mobile station 100 transmits the ACK for the data channel in uplink, channel j control a rising 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 control channel i in the ascending line as the control channel in the ascending line of communication for a mobile station 100a, which is expected, should not transmit SRS. The mobile station 100a uses channel i control the upward communication line for transmission of 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 uplink assigned to the base station 200, the mobile station 100a transmits ACK for the data channel uplink, not on the channel i control a rising line. In this case, mobile stations�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 SRS.

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

Fig.9 illustrates an example of uplink signals including CQI, according to the first embodiment of the. Fig.9 describes how to distribute radioresource in the case where a signal indicating CQI and SRS is multiplexed in potcake Short CP.

In each of the slots of the first and second half of the channel i control a rising 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 ascending Lin�her connection, in each of the slots of the first and second half of the channel j control a rising 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 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 in Fig.8, the control channel j of the ascending line is allocated mobile station, which is supposed to transmit the SRS, and the channel i control a rising 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 SRS, can use all of the characters in potcake for CQI transmission on the control channel in the ascending line.

Fig.10 illustrates another example of the uplink signals, including ACK, according to the first embodiment of the. Fig.10 describes how to distribute radioresource in the case where a signal indicating ACK and SRS is multiplexed in potcake Long CP. Podcat Long CP includes twelve characters. Six characters of the first half slot and the same six characters of the second half (up slot).

In each of the slots of the first and second floors�NY channel i control a rising line, four of these six characters 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 is transmitted the same signal.

Similarly, for channel i control a rising line, in each of the slots of the first and second halves of the channel j control a rising 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 SRS, the first character is used for transmission of SRS and is not used for transmission of ACK.

As described above, in the case of Short CP in Fig.8, the control channel j of the ascending line is allocated mobile station, which is supposed to transmit the SRS, and the channel i control a rising 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 SRS, can use all of the characters in potcake for ACK transmission on the control channel in the ascending line.

Fig.11 illustrates another example of uplink signals including CQI, according to the first embodiment of the. Fig.11 described�em, how to allocate resources in the case where a signal indicating CQE and SRS is multiplexed in potcake Long CP.

In each of the slots of the first and second half of the channel i control a rising 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 a rising line, in each of the slots of the first and second half of the channel j control a rising 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 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 in Fig.9, the control channel j of the ascending line is allocated mobile station, which is supposed to transmit the SRS, and the channel i control uplink 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 SRS, can use all symbols�s in potcake for CQI transmission on the control channel in the ascending line.

Fig.8-11 describe how transmitted ACK or CQI, as an example of signal uplink. 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 can be transmitted within the same potcake.

The following describes how to manage the allocation of radio resources 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 for uplink and SRS multiplexing and signal on the control channel in the ascending line.

Fig.12 is a sequence chart illustrating the control of the distribution in the case where SRS and data uplink overlap. The sequence in Fig.12 will be described step by step. This explanation focuses on the uplink 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 from the mobile station 100 to the base station 200. Then the base station 200 allocates the mobile station 100, the radio resource that should be used for SRS transmission, and sets �nterval transmission. Then the base station 200 transmits the information distribution channel management descending line.

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

(Step S13) After that, the mobile station 100 transmits the SRS in the transmission intervals set in 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 allocation of radio resources on the control channel in the ascending line.

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

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

(Step S17), the base station 200 re-distributes the data channel uplink mobile station 100, after receiving the packet data from the mobile station 100 and then sends the information to provide UL allocation for the downlink control channel of the communication line. After that, the packet data from the mobile station 100 and the distribution of the data transmission channel uplink base station 200 are repeated until the transmission of packet data over.

(Step 318), the base station 200 detects overlapping (overlapping) SRS transmission and packet data from the mobile station 100 in the distribution channel data transmission on uplink, that is, detects that SRS and packet data to be transmitted in the same potcake. Then the base station 200 sends a report of blending with the SRS transmission along with information providing the UL allocation for the downlink control channel of the communication line.

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

(Step S20), the Mobile station 100 transmits packet data on the data channel uplink, distributed in step S18, in characters, except the cat�that are used to transmit 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 quality of communication uplink based on the received SRS. Then after receiving the request for allocation of a data channel for uplink base station 200 selects a range of frequencies that must be distributed on the basis of the results of measuring the quality of communication.

When SRS and the signal on the data channel uplink needs to be multiplexed, the mobile station 100 transmits packet data to the data transmission channel uplink packet data not overlap with the radio resource for SRS transmission.

Fig.13 is a sequence chart illustrating the control of the distribution in the case where SRS and ACK are superimposed. The sequence in Fig.13 will be described step by step.

The following explanation focuses on the uplink 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 from the mobile station 100 to the base station 200. Then the base station 200 allocates the mobile station 100, the radio resource that should be used to transmit SRS, ustanavli�no transmission intervals and then transmits the information distribution channel management descending line.

(Step S22), the Mobile station 100 transmits the SRS radio resource, distributed in step S21, and the base station 200 measures the quality of communication uplink 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 in 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 the transmission channel for downlink data on a downlink control channel of the communication line, and transmits packet data on the data channel downlink.

(Step S25) In response to the packet data received in step S24, the mobile station 100 transmits ACK or NACK on the control channel in the 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 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 transmission channel downlink, the downlink control channel of the communication line, and also transmits the packet �data on the data channel downlink. The packet data is to be transmitted here are a batch of data that must be sent after the ACK will be made in step S25. If NACK is received, the packet data is transmitted last time is transmitted again. After that, the transmission of ACK/NACK from the mobile station 100 and the transfer of packet data from the base station 200 are repeated until the packet data is completed.

(Step S27) In the allocation of 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 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 are assumed not to have to transmit SRS. The distribution of the data channels uplink 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 transmission channel downlink, the downlink control channel of the communication line, and transmits packet data on the data channel downlink.

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

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

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

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

The above description describes a case where one and the same mobile station transmits p�Kenya data or information management and SRS. The same control may refer to the case when different mobile stations transmit them.

In the above communication system is one of the two control channels of upward communication line can be used without interference in respect of the SRS, even in podagra, including the transmission of SRS. Therefore, SRS and the signal control information may be multiplexed in such a way as not to cause deterioration in the quality of communication. 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, base station can measure the quality of a wide range of frequencies.

(The second implementation option)

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

The communication system according to the second embodiment of implementation can be realized by the same configuration as in the first embodiment of implementation. Mobile station and base station according to the second embodiment of the can be implemented such �e configurations of modules as the mobile station 100 and base station 200 in Fig.3 and 4, as in the first embodiment of implementation, respectively. However, the second implementation option transmits and receives SRS and measures the communication quality and the time from the first embodiment. The following description of the second embodiment uses the same reference position of the mobile station and the base station, as the first implementation option.

Fig.14 illustrates an example of uplink signals, including ACK, according to the second embodiment of the. Fig.14 illustrates how to distribute radioresource in the case where a signal indicating ACK and SRS is multiplexed in two consecutive pocketrak Short CP.

In each slot of the control channel i in the ascending 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 SRS, the first character of the second podagra is used for transmission of SRS and is not used for transmission of ACK.

Similarly, for channel i control a rising line in each slot of the control channel j a rising line four of these seven characters allocated for ACK, while the other three are allocated for RS. However, when �bottom or more mobile stations transmit SRS, the first character of the first podagra used for SRS transmission, and is not used for transmission of 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 a rising line, but includes a channel resource j control a rising 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 a rising line, but does not include the channel resource j control a rising line.

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

Fig.15 illustrates an example of uplink signals including CQI, according to the second embodiment of the. Fig.15 illustrates an example of how to distribute radioresource in the case where a signal indicating CQI and SRS is multiplexed in two consecutive pocketrak Short CP.

In each slot of the control channel i in the ascending 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 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 a rising line, in each slot of the control channel j a rising 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 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 Fig.14, a mobile station, which is supposed to transmit SRS, distributed channel j control a rising line St�z first podagra and 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 management ascending line of the second podagra. Therefore, a mobile station which does not transmit SRS, but transmits CQI on the control channel in the ascending line, can use all of the characters in podkraj, even when the other mobile station transmits SRS. Then the base station 200 can measure the communication quality on the basis of signals from SRS taken in the first two characters of the serial podkatov.

Fig.14 and 15 illustrate how transmitted ACK or CQI, as an example of signal uplink. 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 can be transmitted within the same potcake. In addition, Fig.14 and 15 illustrate an example of a Short CP. However, the Long CP can be used as described in the first embodiment of implementation.

Such a communication system can provide the same results as the results of the first embodiment. In addition, the communication system according to a second embodiment of the can �dawlati a reduction in the number of signals, which should multiplicious in time with SRS on the control channel in the ascending line.

(Third implementation option)

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 first embodiment and omitted the explanation of the same features. The communication system according to a third embodiment of the allows a mobile station to perform transmission with diversity antennas, that is, to perform radio communications with multiple antennas.

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

Fig.16 is a block diagram illustrating the functions of a mobile station according to a third embodiment of the. The mobile station 100b includes a transmitting and receiving antenna 110 and 110b, the data processor 120, a processor 330, the pilot signal, the processor 140 of the information control unit 150b resource selection, transmitter 160b, the receiver 170b and the measurement unit 180 to�quality downlink. The data processor 120, processor 130, the pilot signal, the processor 140 of the management information and the block 180 measure the quality of the downlink have the same functions of the respective components as in the first embodiment of the Fig.3.

Transmitting and receiving antenna 110 and 110b are the antennas for transmission and reception. Each transmitting and receiving antenna 110, 110b transmits the uplink signals that are output from the transmitter 160b via radio, to the base station 200a. In addition, the transmitting and receiving antenna 110, 110b receive signals downlink transmitted via radio communication 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.

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

Transmitter 160b identifies radioresource that should be used to transmit pilot data pilot-SIG�Ala and control information on the basis of information secured unit 150b resource selection. Transmitter 160b also selects the transmitting and receiving antenna which should be used for each transmission, on the basis of information provided by the block 150b resource selection. 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 any. If the control information to instruct the switching of the antenna is included in the received signal, the receiver 170b transmits the information on the block 150b resource selection. In addition, the receiver 170b unit 180 provides the measure of quality of the downlink signal, which should be used to measure the quality of communication downlink in respect of a received signal.

Control method for switching the antenna unit 150b resource selection includes the office with an open loop, and run closed loop. When operating with an open loop block 150b resource selection switches between transmitting and receiving antennas 110 and 110b, as planned. For example, the block 150b resource selection periodically switches between transmitting and receiving antennas 110 and 110b.

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

The control method to be adopted, is set in advance in the block 150b resource selection. This implementation option uses a closed-loop control with.

Base station 200a according to a third embodiment of the, can be implemented in the same configuration module in the base station 200 of the first embodiment of Fig.4, except that the communication quality is measured by each of the transmitting and receiving antennas 110 and 110b provided in the mobile station 100b.

Fig.17 illustrates an example of uplink signals, including ACK, according to a third embodiment of the. Fig.17 illustrates how to distribute radiora�URSA in the event that when a signal indicating ACK and SRS is multiplexed in potcake Short CP. 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.17 illustrates the signals that are transmitted from other mobile stations.

As in the above-mentioned first variant of implementation, the mobile station 100b, which are supposed to transmit SRS, distributed channel j control a rising line. Now assume that the mobile station 100b selects the transmitting and receiving antenna 110 for the broadcast. Then the mobile station 110b transmits the ACK signals and RS for channel j control a rising line from the transmitting and receiving antenna 110. The mobile station 110b transmits SRS inthe 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 qualities� communication as transmission, and the receiving antennas 100 and 100b.

Fig.18 illustrates an example of uplink signals including CQI, according to a third embodiment of the. Fig.18 illustrates how to distribute radioresource in the case where a signal indicating CQI and SRS is multiplexed in potcake Short CP.

The mobile station 100b transmits CQI signals and RS for channel j control a rising line from the transmitting and receiving antenna 110. The 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 communication quality of the transmission and the receiving antennas 110 and 110b.

Meanwhile, only formobile station 100b to select the antenna that needs to be used, there is no need to measure the transmission quality of a wide range of frequencies. Additionally, if the mobile station 100b has no packet data for transmission on uplink within a predetermined period of time, with basic�anzia 200a does not require measurement of the quality of transmission frequencies, which can be used for data transmission channel uplink. Therefore, while there is no packet data to be transmitted in uplink, the mobile station 100b transmits the SRS transmission at frequencies different from the frequency range of the control channel in the ascending line.

Fig.19 illustrates another example of the uplink signals, including ACK, according to a third embodiment of the. Fig.19 illustrates how to distribute radioresource in the case where a signal indicating ACK and SRS is multiplexed in potcake Short CP and the mobile station 100b has packet data to transmit.

The mobile station 100b transmits ACK signals and RS for channel j control a rising line from the transmitting and receiving antenna 110. The mobile station 100b alsotransmits SRS only with the frequency range of channel j control a 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, but allows bazo�th station 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 in the ascending line of communication, the mobile station 100b in advance provides the base station 200a notification that the mobile station 100b has packet data to transmit.

Fig.20 illustrates another example of uplink signals including CQI, according to a third embodiment of the. Fig.20 illustrates how to distribute radioresource in the case where a signal indicating CQI and SRS is multiplexed in potcake Short CP and the mobile station 100b has packet data to transmit.

The mobile station 100b transmits CQI signals and RS for channel j control a rising line from the transmitting and receiving antenna 110. The mobile station 100b transmits SRS only with the frequency range of channel j control a 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 nal data transmission on uplink, but allows the base station 200a to obtain information that should be used by the mobile station 100b to select the antenna that should be used.

Fig.17-20 illustrate how transmitted ACK or CQI as an example of signal uplink and like the 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.17-20 illustrate an example of a Short CP, Long CP can be used as described in the first embodiment of implementation. Additionally, SRS can be transmitted in the first two characters of the serial podkatov, as described in the second embodiment of implementation.

Such a communication system can provide the same results as the results of the first embodiment. Additionally, the communication system according to a third embodiment of the, the measurement of communication quality on the basis of signals from SRS can be used to select the antenna with the spacing of the antennas. Additionally, when the mobile station has no packet data for transmission, the frequency range may be reduced for SRS transmission, thus reducing the load� on measurement of the communication quality to the base station.

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

The foregoing description is considered as the only illustration of the principles of the present invention. Further, since numerous modifications and changes will be obvious to those 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.
