The technical field to which the invention relates.

The present invention relates to systems LTE (Long Term Evolution) and more subject relates to base stations and mobile stations.

The level of technology

The achievement of high efficiency of frequency use is possible with fast packet scheduling, where each transmission interval or each resource block (RB)obtained by dividing the frequency band of the transmission interval, transmission are assigned to users based on the state of the receiving channels.

However, to implement a fast packet scheduling must be transmitted from the base station to the user terminal assignment information for each transmission interval or each resource block, and the condition of the transmission must be transmitted from the user terminal to the base station, which may increase the cost of the alarm system.

The use of the above-described fast packet scheduling can be difficult when traffic packages almost fixed size and a constant cycle of emergence, as if audiologic and hard requirements to the delay. With this traffic, even if the data must be transmitted in conditions of poor reception, it is unacceptable to delay the transmission of, for example, in anticipation of improving the reception status. Accordingly,it may be necessary to traffic when radioresource can be allocated a fixed manner at a constant cycle without regard to the reception status.

Therefore, for traffic with periodic occurrence data, such as VoIP, offers long-term planning for the periodic assignment of pre-defined radioresource, as described in Ericsson, R1-060099 "Persistent Scheduling for E-UTRA", TSG-RAN WG1 LTE AdHoc, Helsinki, Finland, January 23-25, 2006.

However, this proposal is conceptual in nature and does not contain details about the device, the base station and the mobile station.

Thus, the aim of the present invention is to offer a base station and a mobile station capable of periodically assign predefined radioresource for traffic with the periodic appearance of the data.

For the solution of the given problem, one aspect of the present invention relates to a base station in which the mobile station is assigned the resource blocks obtained by dividing the frequency band of the system into blocks of consecutive frequency subcarriers or resource blocks of distributed type, consisting of carrier frequencies, discretely distributed over the frequency band of the system, and the resulting segmentation blocks resources on multiple resource blocks. The base station device includes planning, made with prob is the possibility of the destination mobile stations of the resource blocks or resource blocks of distributed type with a predetermined cycle based assignment transmitted from the mobile stations status of receiving channels descending line.

With this configuration, radioresource for the mobile station can be assigned statically or fixed manner in a predetermined cycle.

Another aspect of the present invention relates to a base station that includes a destination device of the transmission bandwidth of the pilot channel is arranged to measure the state of the receiving channel uplink communication with a cycle longer than the cycle of the destination channel data; a destination device of the transmission bandwidth of the data channel is configured to assign as the transmission bandwidth of the data channel for the mobile station resource blocks obtained by dividing the frequency band of the system into blocks of consecutive frequency subcarriers; and a forming device control information that is made with the possibility of forming a control signal for informing mobile stations about-defined to assign the width of the transmission bandwidth of the pilot channel and the width of the transmission bandwidth of the data channel, and in which the destination device strip transmission of the data channel is configured to assign transmission bandwidth of the data channel based on the reception quality of the pilot channel.

With this configuration, the frequency band of transmission of the pilot channel for measuring the status of premenopausal uplink communication may be prescribed cycle, which is longer than the cycle of the destination of the data channel, and to determine the purpose of the transmission bandwidth of the data channel for the mobile stations based on the reception quality of the pilot channel.

Another aspect of the present invention relates to a mobile station, comprising forming device of the pilot signal is performed with use of a frequency band assigned to a base station for forming a pilot channel to the base station with a cycle that is longer than the cycle of the destination of the data channel; and a destination device of the data transfer performed with destination data transmission with a predetermined cycle assignment for the resource block defined in a base station based on the pilot channel.

The implementation of the invention

The following, with reference to the drawings describe the best way to implement the present invention.

In all the drawings illustrating the implementation, the components and elements performing the same functions are denoted by the same symbols and their repeated descriptions are omitted.

System for mobile communication with the availa able scientific C this implementation includes a base station 100 and mobile station 200. The base station 100 and mobile station 200 periodically assign the mobile station 200 and the base station 100, respectively predefined radioresource for traffic with the periodic appearance of the data.

As described above, when the fast packet scheduling frequency domains, in which the base station 100 assigns resource blocks to the mobile station 200 based on the frequency selectivity and the status of the receiving channel, you can increase the amount of transmitted control signals L1/L2, such as information about assigning resource blocks to the mobile station 200 and feedback about the state of the receiving channel from the mobile station 200.

Since the primary purpose of long-term planning is to reduce the number of control signals L1/L2, for long-term planning in relation to a mobile communication system in accordance with this implementation you can use the following method transfer for which it is possible to expect the effect of frequency diversity. As noted above, long-term planning is a method of planning for periodically assigned predefined radioresource for traffic with the periodic appearance of the data.

In downward communication is used multiple access orthogonal frequency division OFDMA (Orthogonal Frequency Division Multiple Access). OFDMA pre is is a scheme, in which data is transmitted in several more narrow frequency bands (subcarriers), obtained by dividing the frequency band. Since the subcarriers overlap each other in frequency, but can densely arranged without mutual interference, it is possible to realize transmission with higher speed and more efficient use of frequency.

In addition, top-down communication lines using a distributed scheme transfer-level resource block, using the block division. Namely, as shown in figure 1, each user is assigned the resource blocks of distributed type. Distributed resource blocks obtained by segmenting resource blocks (segmentation units), consisting of discretely distributed subcarriers of frequencies within the bandwidth of the system and obtained by dividing the frequency band for several consecutive frequency subcarriers. The resource blocks of distributed type are assigned to a distributed way within one transmission interval. The resource blocks of distributed type are assigned on a block-level resources, i.e. in units of resource block. In downward communication lines instead of the above-described resource blocks of distributed type, each user can be assigned resource blocks obtained by dividing the frequency band sistemine blocks of consecutive frequency subcarriers.

Figure 1 illustrates a typical layout of the resource block, consisting of two resource blocks of distributed type. The same resource blocks of distributed type can be assigned to a pre-determined cycle of destination or different resource blocks of distributed type can be assigned to different cycles of destination. The effect of frequency diversity can be achieved by changing the resource blocks of distributed type for different cycles of destination. Here, the term "cycle of appointment" means a cycle in which the user is assigned resource blocks of distributed type. The cycle may depend on the data type, and, for example, for voice over Internet Protocol VoIP (Voice over Internet Protocol) cycle may be 20 MS and to be closer to the transmission interval of the packet.

In this transfer method, if for adaptive tuning schemes modulation and velocity encoding with error correction depending on the change of propagation conditions in downstream communication lines used adaptive modulation and coding AMC (Adaptive Modulation and Coding), the mobile station should only return averaged over the frequency domain condition of the receiving channel. As a result, to achieve frequency diversity base station 100 may transmit on the basis of only temporary changes of priem the second channel, averaged over the entire frequency domain.

For bottom-up communication lines used multiple access orthogonal frequency division and one subcarrier SC-FDMA (Single-Carrier Frequency Division Multiple Access). SC-FDMA is a transmission scheme that allows to reduce the mutual influence of several terminals by use of terminals of different frequency bands for transmission.

In addition, as shown in figure 2, for the ascending lines of communication technique is focused transmission using frequency-hopping. Namely, the resource blocks obtained by dividing the frequency band for several consecutive subcarriers of frequencies that are assigned to mobile stations with a predetermined cycle of destination, and their frequency is abruptly changed, thus providing the effect of frequency diversity. Here, the term "frequency hopping" means that the assigned resource blocks modified in each transmission interval, and the term "cycle of appointment" means a cycle in which users are assigned resource blocks. The cycle may depend on the type of data and, for example, for voice over Internet Protocol VoIP (Voice over Internet Protocol) can be 20 MS, which is close to the transmission interval of the packet.

The following describes the typical way to achieve efficiency is but temporary explode.

When using a hybrid automatic request for repetition of HARQ (Hybrid Automatic Repeat Request) is a combination of automatic request for repetition of ARQ and coding with error correction for the implementation of required HARQ signaling, which increases the cost of the alarm system.

For example, when using asynchronous HARQ type transmission intervals or blocks of resources for re-transmission should be assigned dynamically, which requires signaling for transmission of ACK/NACK for the transfer request and retransmission of the prescribing information. Asynchronous HARQ type can be used as the assignment method to assign opportunities for re-transmission after a predefined period of time after the initial transmission, for example at an arbitrary point in time after a predefined period of time after the transmission of the ACK/NACK from the receiving side.

For example, when using synchronous HARQ type the purpose of re-transmissions is fixed. In the alarm to the prescribing information optional, and alarm for ACK/NACK to request retransmission is required. Synchronous HARQ type can be used as the assignment method to assign opportunities for re-transmission after a predefined period of time after the PTO is the initial retransmission, for example, at an arbitrary time after a predefined period of time after the transmission of the ACK/NACK from the receiving side.

In accordance with this implementation in the mobile communication system to achieve the effect of temporary explode without the use of HARQ is performed a predetermined number of transmissions.

In this case, the same data may be transmitted twice or sequence data after channel coding can be separated into several podkatov.

Figure 3 illustrates a typical mode of transmission in downlink communication lines. In this implementation, the sequence of data after channel coding is divided into several podkatov, for example two podagra. In this case, several resource blocks of distributed type, such as two blocks of the distributed type resources are used for each of the two gears. Thus, an encoded sequence of data when the assignment is divided into four podagra.

Since the encoded sequence of data is divided into two frames during transmission, it is possible to achieve the effects of temporal explode, resulting in reduced errors during receiving. A problem may arise that the decoding cannot be started until the completion of the two techniques. However, when the cycle of the destination sostav the em 20 MS, and the transmission interval of the same data is equal to 10 MS, the latency may be about 10 MS, which may be acceptable.

Figure 3 illustrates a typical transfer method in ascending lines. In this implementation, the sequence of data after channel coding also is divided into several podkatov, for example two podagra. Namely, since an encoded sequence of data is divided into two frames during transmission, it is possible to achieve the effects of temporal explode, resulting in reduced errors during receiving. A problem may arise that the decoding cannot be started until the completion of the two techniques. However, in the case when the cycle is 20 MS, and the transmission interval of the same data is equal to 10 MS, the latency may be about 10 MS, which may be acceptable.

In addition, in accordance with this implementation in the mobile communication system to provide the required frequency of occurrence of packet errors PER (Packet Error Rate) apply adaptive modulation and coding AMC and power control transmission of TPC (Transmission Power Control).

In the case of using AMS if you change your schema modulation and coding (MCS Modulation and Coding Scheme), that is, combinations of modulation scheme and coding rate, error correction, which are BA the new station 100 for each mobile station 200 based on the reception quality and/or other parameters measured by the mobile station 200 may change the required radioresource, such as the number of resource blocks of distributed type. However, the simultaneous use of TRS can make assigning resource blocks are optional.

For example, the management of AMC with long cycle (cycle longer than the cycle of the destination, such as hundreds of microseconds) can be combined with TRS cycle is based on destination. In this case, the AMS and assigning resource blocks are changed rarely and therefore to transfer changes are used to signal the senior level. These signals can occur when the status change reception. The control signals L1/L2 can also be used as signals for the user other than the user, subject to long-term planning. When using control signals L1/L2 in advance to reserve radioresource.

In addition, in accordance with this implementation in a mobile telecommunications system long term planning is implemented in the mobile station 200.

In this case, feedback on the status of the receiving channel from the base station 100 to the mobile station 200, that is, information that specifies the width of the transmission bandwidth of the pilot channel for measuring the status of the receiving channel defined for the destination (in the downlink), and the transmission from the mobile station 200 is a base station 100 of the pilot signal for measuring the status of the receiving channel (uplink communication) has cycles longer than the cycle of the assignment. And these cycles can be longer than the cycle of the destination channel data.

In long-term planning downlink feedback about the state of the receiving channel is transmitted in the following way. Namely, the base station 100 carries out long-term planning based on feedback information about the state of the receiving channel from the mobile station 200. Mobile station 200 uses the ascending line of communication to send feedback on the mean state of the reception in the frequency band of the reception with a constant cycle. This cycle is made longer than the cycle of the purpose of the current channel data.

Mobile station 200 transmits the status of the receiving channel in the random access channel RACH (Random Access Channel). In other words, the mobile station 200 transmits the status of the receiving channel signals through the senior level (L3). To send the status of the receiving channel of the mobile station 200 may also use the radio resource with defined time and frequency, which are periodically assigned in advance. In this case, the radio resource used for transmission, is determined and transmitted at the beginning of the communication session when making long-term planning. In case of change of MCS radio resource also States again.

In the long term upward communication is ignal measuring the status of the receiving channel is transmitted in the following way. Namely, the mobile station 200 transmits to the base station 100 a pilot signal for measuring the status of the receiving channel uplink communication. The base station 100 uses a pilot signal transmitted from mobile station 200, for measuring the reception status of the ascending line.

The base station 100 transmits the status of the receiving channel uplink communication as described above, a distributed transmission and information indicating the bandwidth of the transmission channel data in the resource block of the distributed type, i.e. the width of the transmission bandwidth equal to the bandwidth for frequency planning. They can also be transmitted in the assigned frequency band when concentrated transmission. Focused transmission is a transmission method in which each user is assigned a resource block obtained by dividing the frequency band of the system into blocks of consecutive frequency subcarriers. In this case, when the location of the mobile station 200 away from the base station 100 and, as a consequence, it is necessary to transmit in a wider band of frequencies centered transfer can be performed for several times, those two or more times. In other words, for transmission can be assigned to two or more transmission interval.

The following describes a typical release unit is in resources in long-term planning downlink.

As shown in figure 5, if the base station 100 no data intended for transmission to a particular user, the base station 100 releases the resource block or resource block of the distributed type, assigned in long-term planning, and reassigns it to other users. In other words, if the base station 100 is data intended for transmission to a target user, the base station 100 assigns a resource block or a block of frequencies distributed type; otherwise, the base station 100 releases the resource block or the block of frequencies distributed type you want to assign, and reassign it to other users.

Transmitted from the base station 100, the data may include control using a cyclic redundancy code CRC (Cyclical Redundancy Check), overlapping with the user ID UE-ID. Mobile station 200 extracts the CRC, overlapping with UE-ID of the transferred data. Therefore, if the resource block or resource block of the distributed type assigned to another user when checking the CRC can detect error due to incompatibility UE-ID, overlapping with CRC. Thus, mobile station 200 may determine are whether the transferred data. Further, if control re-transmission user terminal (mobile station is 200) transmits a NACK as a request for retransmission, but the base station 100 may ignore this request.

The following describes typical freeing resources in long-term planning of the ascending line.

In the ascending lines in contrast to the above-mentioned top-down lines of communication mobile station 200 transmits a signal on the availability of data transmitted to the base station 100 for the release of resource blocks assigned in long-term planning.

Below are described three methods for transmission to the base station 100 a signal of the presence of transmitted data.

As shown in figa, if the transmitted data of the mobile station 200 communicates to the base station 100 (the base query about the assignment). For example, a request for assignment to assign resource blocks in the presence of transmitted data is transmitted in a predetermined cycle, such as cycle destination.

Also, as shown in figv, in the absence of data transmitted, the mobile station 200 reports the absence to the base station 100 (the base query on release). For example, a request for release to release blocks of resources in the absence of transmitted data is transmitted in a predetermined cycle, such as cycle destination.

Also, as shown in figs, the base station 100 is informed of the occurrence of the transmitted data and that the data being transmitted is scarponi (a combination of requests for appointment and release). For example, in a predetermined cycle, such as cycle destination, if the transmitted data of the mobile station 200 transmits a request for assignment to assign resource blocks, and Vice versa, in the absence of data transmitted, the mobile station 200 transmits a request for release to release blocks of resources.

These signals report also transmitted in the random access channel RACH (Random Access Channel). In other words, they are passed through signal-to senior-level (L3). Also for transmitting signals of the report can be used radioresource defined by time and frequency and appointed from time to time in advance. In this case the exclusive purpose radioresource allows you to enter the orthogonalization among users, thereby improving the reception quality. In another way, because radioresource statically assigned in advance, the signals of the report can multiplicious in CDMA (Code Division Multiple Access, multiple access, code division among fewer users.

The following describes a typical temporary destination parameters for data and information management.

In audiologic it is assumed that radioresource in upward communication and downward communication lines are assigned statically. In this case, the effective transmission of information management can be achieved is by optimizacija time static assignment radioresource in upward communication and downward communication lines, including the appointment of radioresource for transmitting control information.

Radioresource to send the status of the receiving channel in the descending lines of communication, availability of data transmitted in the uplink communication and the ACK/NACK for data transmission in downlink are assigned immediately before the transfer in the downlink. Thus, the state of the receiving channel downlink can be taken into account when adapting the channel for transmission in the downlink. In addition, the transmission of data availability in the ascending line of communication allows you to reassign to other users unused radioresource uplink communication. In this case, the resulting reassignment transmitted simultaneously with data transmission in the downlink.

Radioresource for data transmission in uplink communication are assigned after data transmission in the downlink. Thus, when the release radioresource for data transmission in uplink communication, the resulting reassignment may be reported to the designated users. ACK/NACK for data transmission in the downlink can be transmitted together with data transmission in uplink communication.

The typical characteristic time parameters destination for transferring data and control information are described with reference to figa and 7B./p>

The described case with the appearance of the data in the ascending line.

In step S702 user terminal (mobile station 200) transmits one or more feedback signals about the state of the receiving channel downlink, the request for designation or request for release and ACK/NACK for data transmission in the downlink. In this case, when data for uplink connection request is transmitted to the destination.

In step S704, the base station 100 carries out the adaptation of the channel or the AMC based on the state of the receiving channel downlink transmitted in uplink communication, and transmits the data downlink on the basis of the results of the adaptation channel. In addition, when the transmission request for release from the user terminal, the base station 100 transmits information about the distribution podkatov data downlink for users other than the user, subject to long-term planning. In addition, the base station 100 transmits assignment information for transmission in uplink communication. When the release radioresource for users subject to long-term planning, these radioresource are assigned to users other than the user, subject to long-term planning.

In step S706 user terminal transmits the data uplink communication. Here, the user terminal can simultaneously transmit ACK/NACK in response to the transmission of data downlink.

In step S708, the base station 100 transmits ACK/NACK in response to the transmission of data downlink.

The described case with the appearance of data in the downlink.

In this case, run the above steps S702 and S704.

Namely, in step S702 user terminal (mobile station 200) transmits one or more feedback signals about the state of the receiving channel downlink and a request for designation or request for release.

Then the base station 100 carries out the adaptation of the channel based on the state of the receiving channel downlink transmitted in uplink communication, and transmits the data downlink on the basis of the results of the adaptation of the channel.

In step S704, the base station 100 transmits information about the distribution of podkatov for data downlink for users other than the user, subject to long-term planning. In addition, the base station 100 transmits assignment information for transmission in uplink communication. When the release radioresource for users subject to long-term planning, these radioresource are assigned to users other than the user, subject to long-term planning is to implement.

The following describes a typical device of the base station 100 and mobile station 200 for implementing the above-mentioned mobile communication system. In the following the implementation of the base station 100 and mobile station 200, for which long-term planning is used in downlink, the base station 100 and mobile station 200, for which long-term planning is used in uplink communication, described separately, but the base station 100 and mobile station 200 may be designed to perform both of these functions.

The base station 100 and mobile station 200, for which long-term planning is used in downlink, as described with reference to Fig and 9.

The base station 100 includes a radio receiving device 102, the device 104 demodulation and decoding, connected to the receiving device 102, the scheduler 106, connected to the device 104 demodulation and decoding unit 108 destination priority definition and management of resource blocks that are connected to the scheduler 106 and the device 104 demodulation and decoding device 110 receiving the header information, the device 114 identification of the package, connected to the device 110 receiving the header information, the device 112 control buffer, connected to the device 110 receiving the header information, the mouth is oistu 114 identifies the package and scheduler 106, the device 116 formation Protocol unit PDU (Protocol Data Unit)connected to the device 114 identification of the packet, the buffer 118 transmission, connected to the device 116 forming PDU and the device 112 controls the buffer, the selector 120, connected to the buffer 118 transmission and the scheduler 106, the device 122 encoding and modulation, is connected to the selector 120 and representing one or more means for encoding and modulating and transmitting unit 124 connected to the device 122 encoding and modulation and serves as a means of controlling transmit power, and the device 126 forming the control signal, is connected to the transmitting device 124 and the scheduler 106.

Radio receiver 102 receives the control signals, including information management, from the mobile station 200 and supplies the received control signals to the device 104 demodulation and decoding. The device 104 demodulation and decoding demodulates and decodes the control signals. The scheduler 106 transmits information management uplink communication state of the receiving channel downlink for the respective resource blocks) from the mobile stations 200, such as quality indicators channel CQI (Channel Quality Indicator) of the respective resource blocks for the user terminal.

Also, if the mobile station 200 transmits feedback about the state of the receiving channel by the control signals, the senior level, the control signals of this senior level are fed to the device 108 destination priority definition and management of resource blocks. The device 108 prioritize, define and control blocks resource specifies the resource block to assign priority and sends it to the scheduler 106.

Receiving from the network an IP packet, the device 110 information extracts the header information of the packet header, such as the destination address of a received IP packet, and delivers the received header information of the packet to the device 112 buffer management. The IP packet is supplied to the device 114 that identifies the package.

The device 112 controls the buffer specifies the device 114 identification packet storage location of the data packet based on the header information transmitted packet and the status of their corresponding queues are transmitted from the buffer 118 transmission, as described below. In addition, the device 112 buffer management submits to the buffer 118 transmission destination address and the address of the queue in the memory in accordance with the target address. The device 112 buffer management informs the scheduler 106 information about the packet header and the corresponding status of queues that are transmitted from the buffer 118 transfer.

The device 114 that identifies the package identifies incoming IP packets based on the designated data storage package specified device 112 is Board buffer, and one takes the identified packets to the device 116 forming the PDU. The device 116 forming PDU converts the received packets in the PDU and delivers them to the buffer 118 transfer.

The buffer 118 transfer of the received PDU forms an individual queue for each destination (mobile station 200) and transmits the status of queues device 112 controls the buffer.

The selector 120 retrieves the data from the queue specified by the scheduler 106, and indicating the associated resource block passes them to the device 122 encoding and modulation. This resource block is assigned by the scheduler 106.

The scheduler 106 determines the values of priority for assigning resource blocks to users based on resource blocks assigned according to the priority information of the packet header and the corresponding status of queues defined on the basis of the transmitted from the mobile station 200 to the management uplink communication state of the receiving channels downlink blocks of frequencies) and/or control signals transmitted from the senior level [alarm]. Then based on these values, the scheduler 106 determines the assignment of resource blocks. Namely, the scheduler 106 may be assigned to either the resource blocks obtained by dividing the frequency band of the system into blocks of consecutive frequency subcarriers, or RA is definitely the resource blocks, consisting of frequency subcarriers distributed over the frequency band of the system, and the resulting segmentation blocks resources.

In addition, as mentioned above, the scheduler 106 adjusts the adaptive modulation scheme and/or coding rate of error correction depending on the change of propagation conditions. Namely, the scheduler 106 modifies the used MCS, that is, combinations of modulation and velocity encoding with error correction of transmitted data, determined for each mobile station 200. Information indicating the combination of the modulation scheme and the coding rate with error correction data to be transferred, is fed to the device 126 forming the control signal. The device 126 forming the control signal generates the control signal indicating the received modulation scheme and encoding rate of the error correction of transmitted data, and transmits the control signal through the transmitting unit 124. In addition, the scheduler 106 specifies a predefined and fixed number of transmission.

The device 122 coding and modulation encodes and modulates the data obtained on the basis of a specific MCS and transmits the coded and modulated data to the mobile station 200 using a radio transmitting device 124 to control the transmit power. For example, MCS change who I am in a longer cycle, than the cycle of the destination, and the transmission power is changed in a cycle of destination.

Mobile station 200 includes a receiving unit 202, the device 204 separation of the signals of subcarriers is connected to the radio receiving unit 202, the device 206 channel estimation, is connected to the device 204 separation of the signals of subcarriers device 208 CQI measurement in the descending line, connected to the device 204 separation of the signals of subcarriers and the device 206 channel estimation, the device 210 of the data generating feedback, connected to the device 208 CQI measurement in the downlink, the device 212 encoding and modulation, is connected to the device 210, the data generating feedback transmitting unit 214 connected to the device 212 encoding and modulation, the device 216 storing information about the scheduled resource blocks that are connected to the device 204 separation of the signals of subcarriers device 218 demodulation connected to the device 204 separation of the signals of subcarriers and device 216 storing information about the scheduled resource blocks, the device 220 decoding, connected to the device 218 demodulation device 222 detection CRC, connected to the device 220 decoding, and the device 224 restore IP packets that are connected to the device 222 detection of CRC.

Then I am glad priemnoe device 202 receives a pilot channel from the base station 100. Radio receiving unit 202 takes the pilot channel to the device 204 separation of the signals of subcarriers. The device 204 separation of the signals of subcarriers allocates individual signals of the subcarriers of the pilot channel and feeds each of the selected individual signals of subcarriers to the device 206 channel estimation and device 208 CQI measurement in the downlink.

The device 206 channel estimation uses a pilot symbol to determine the values of channel estimation for carriers and delivers the values of the channel estimation device 208 CQI measurement in the downlink. The device 208 CQI measurement in a downlink measures the average CQI in the frequency band of transmission of the pilot channel and delivers the measured average CQI to the device 210 generate the data feedback. The device 210 of the data generating feedback based on the received CQI generates feedback information (management information)indicating the state of the receiving channel downlink as feedback information to the base station and sends feedback information to the device 212 encoding and modulation. The device 212 encoding and modulation encodes and modulates the information feedback and uses radio transmitting device 214 for transmission of the coded and modulated information feedback to the gas station 100. For example, the radio resource for transmitting the status of the receiving channel downlink is assigned immediately before the transfer in the downlink.

In addition, the radio receiving unit 202 receives signals transmitted from the base station 100. Radio receiving unit 202 supplies the received signals to the device 204 separation of the signals of subcarriers. The device 204 separation of the signals of subcarriers allocates individual signals of subcarriers of the received signal and feeds each of the selected individual signals of subcarriers per device 218 demodulation.

The device 218 demodulation demodulates the received individual signals of subcarriers based on the information about the scheduled resource blocks stored in the device 216 storing information about the scheduled resource blocks, and supplies each of the demodulated signals to the device 220 decoding. In this implementation, the information about the assigned resource block may include a control channel transmitted from the base station 100, for example, the control channel L1/L2. In addition, information about the scheduled resource block may include, for example, MCS.

The device 220 decoding decodes the received signals and supplies the decoded signals to the device 222 detection of CRC. The device 222 detection CRC detects CRC, overlapping with U-ID included in the transmitted data for error correction, and determines whether data to be transmitted to the mobile station 200. If the transmitted data intended for the mobile station 200, the device 222 detection CRC submits data to be transmitted to the device 224 recovery of IP packets. The device 224 restore IP packets restores received data.

Next, with reference to figure 10 and 11 described base station 100 and mobile station 200, in which long-term planning is used in the ascending lines.

The base station 100 includes a radio receiving device 102, the device 104 demodulation and decoding and device 128 measuring CQI, connected to the receiving device 102, the scheduler 106, connected to the device 104 demodulation and decoding unit 108 destination priority definition and management of resource blocks that are connected to the scheduler 106 and device 128 measuring CQI, the device 126 forming the control signal, is connected to the scheduler 106, and a radio transmitting device 124 connected to the device 126 signal control.

The scheduler 106 assigns to the mobile station 200 frequency band of transmission of the pilot channel for measuring the status of the receiving channel uplink communication in a cycle longer than the cycle of the destination of the data channel. Information indicating the purpose is the transmission bandwidth, served on the device 126 forming the control signal and is transmitted via the transmitting device 124.

Mobile station 200 transmits the signals to measure the state of the respective receiving channels to the base station 100 in the assigned frequency band of a pilot channel. Radio receiver 102 receives signals for measuring the status of the receiving channels, and sends the received pilot signals to measure the state of the receiving channels of the device 128 CQI measurement. The device 128 measuring CQI measures the reception quality, such as CQI, and provides information on the measured reception quality along with the signals for measuring the status of channels on the device 108 destination priority definition and management of resource blocks. In addition, a receiving unit 102 receives the information indicating the presence of a transmitted data in the mobile station 200, and delivers this information to the device 108 prioritize, define and manage resource blocks through the device 128 CQI measurement.

Transmitting device 124 transmits the control signal received from the device 126 forming the control signal, the mobile station 200. In the prescribing information transmission in uplink communication may be transmitted from base station 100 to the mobile station 200.

For example, radioresource for data transmission in the uplink communication may be appointed after the transfer and data downlink. In other implementations, the scheduler 106 may determine different combinations of modulation and velocity encoding with error correction for mobile stations 200 with a cycle longer than the cycle of the destination, and to transmit certain combinations of modulation and velocity encoding with error correction in the quality of management information.

The device 104 demodulation and decoding demodulates and decodes the received data to be transmitted. The device 104 demodulation and decoding transmits CQI individual resource blocks uplink connection for each user terminal, the scheduler 106.

The scheduler 106 determines the reassignment of resource blocks in a predetermined cycle destination based on the CQI received from the device 104 demodulation and decoding, and gives some information about assigning resource blocks to the device 126 forming the control signal. The device 126 forming the control signal generates information about the purpose of the transmission bandwidth in uplink communication based on the information about the assignment of resource blocks, as defined by the scheduler 106, and podaa the prescribing information on the wireless device 124. Transmitting device 124 transmits the control signal received from the device 126 forming the control signal, the mobile station 200.

IP packets from the senior level are fed to the device 226 information header. The device 226 information extracts the header information of the packet header, such as the destination address of the received IP packet, and delivers the received header information of the packet to the device 234 buffer management, and delivers the IP packets to the device 228 formation of the PDU.

The device 228 forming PDU converts the received packets in the PDU and sends this PDU to the buffer 230 transmission. The buffer 230 transmission generates a queue for the destination (base station 100) from the received PDU based on the target address received from the device 112 buffer management, and addresses the corresponding line in the memory and transmits the status of the queue device 234 control buffer.

The base station 100 transmits the device 234 of the buffer management information indicating the assigned bandwidth of the transmission channel data.

The device 234 control buffer transmits the status of the queue, transferred from the buffer 230 transmission, and the header information of the packet to the device 236 forming data feedback. Device 236 forming data feedback forms feedback information, indicating the presence of a transmitted data based on the received status of the queue and sends feedback information to the device 238 encoding and modulation.

SUBSTANCE: method is described to transfer a probing reference signal in an upperlink at duplex mode with time-division channelling, where a terminal calculates parameters of resources for transfer of a SRS signal in a time slot UpPTS in compliance with the information on configuration related to the SRS signal in the upperlink. Above parameters contain the initial position of resources in the frequency area, and then the SRS signal is transmitted using resources; at the same time, when the initial position is calculated in the frequency area of resources, the index of the first subcarrier should be identified in the maximum throughput capacity of SRS. The terminal determines the above index with the help of the position in the frequency area of one or more channels of random access, i.e. PRACH channels in the UpPTS time slot. When the PRACH channel includes subcarriers at the lower border of the system throughput capacity, the upper border of the system throughput capacity is applied as the final position of the maximum throughput capacity of SRS, and the initial position of the maximum throughput capacity of SRS is calculated. When the PRACH channels include subcarriers at the upper border of the system throughput capacity, the lower border of the system throughput capacity is applied as the initial position of the maximum throughput capacity of SRS, and then the above index is determined by adding the initial position of the maximum throughput capacity plus the offset parameter configured for the terminal.
