3GPP TS36.211 V13.2.0, June 2016

  When communication by repeated transmission is performed between a base station apparatus and one terminal apparatus, wireless resources that are temporally continuous are allocated for the communication. Here, as the number of times of repeated transmission increases, the number of continuously allocated radio resources also increases. For this reason, there has been a problem that a radio resource is occupied for a very long time for communication with one terminal device, and another terminal device may not be able to communicate.

  The present invention has been made in view of such a problem, and provides a technique for appropriately assigning a communication opportunity to a terminal device according to a situation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(System configuration)
FIG. 1 shows a configuration example of a wireless communication system according to the present embodiment. The wireless communication system includes, for example, a base station device 101, a first terminal device 102, and a second terminal device 103. FIG. 1 shows an example including one base station device and two terminal devices for the sake of simplicity, but the wireless communication system has a large number of base stations as in a normal cellular communication system. Device and a number of terminal devices. Hereinafter, the first terminal apparatus 102 may be referred to as UE A, and the second terminal apparatus 103 may be referred to as UE B.

  It is assumed that this wireless communication system can use at least MTC (Machine Type Communication) defined by 3GPP, and can execute communication with extended coverage using the above CE mode. That is, the present radio communication system uses the MTC frequency band (frequency band for 6 resource blocks) to repeatedly transmit a signal between the base station apparatus 101 and UE A or UE B to thereby obtain a predetermined signal. It is configured so that communication with wireless quality (for example, SIR (signal-to-interference power ratio) = 3 dB) can be performed. Note that the repeated transmission here refers to Repetition defined by 3GPP, but other repeated transmission techniques may be used. In the following, it is assumed that communication by MTC is performed in the present wireless communication system, but communication may be performed in any other system that can provide wide coverage with low power.

  In addition, UE A and UE B adopt a half-duplex scheme, and perform communication on the downlink (wireless link in the direction from the base station apparatus 101 to the UE A or UE B) and uplink (from the UE A or UE B to the base station). Communication with a wireless link in the direction of the station device 101) is executed in a temporally switched manner. In other words, uplink communication is not performed during downlink communication, and downlink communication is not performed during uplink communication. On the other hand, the base station apparatus 101 employs a full-duplex scheme and can simultaneously perform uplink communication and downlink communication. That is, the base station apparatus 101 can communicate with UE B on the uplink while communicating with UE A on the downlink, for example.

  When performing repeated communication in the CE mode, when performing communication with a certain UE by using a large number of repetitions, radio resources are occupied for a long period of time for the communication, during which communication with another UE is performed. May not be possible. Also, at this time, if the communication with another UE is a communication requiring real-time properties (for example, VoLTE (Voice over Long Term Evolution)), a problem may occur such that the real-time demand cannot be satisfied. When data to be transmitted with priority is not given priority and communication with a large number of repetitions is started, it may be necessary to wait for a long time until the communication is completed, which causes inconvenience in system operation. There are cases.

  For this reason, in the present embodiment, in a state where the base station apparatus 101 allocates one or more first wireless resources that are temporally continuous for communication with the first UE, the first When the communication of the second UE, which should be prioritized over the communication with the UE, is requested, the communication with the first UE is not performed in the second radio resource included in the allocated first radio resource. Then, communication with the second UE is performed. According to this, even when a radio resource is allocated for communication with a relatively low priority, interruption of communication to be prioritized is allowed, and delay until completion of communication to be prioritized is suppressed. can do. This is illustrated in FIG.

  FIG. 2A shows a state in which radio resources are allocated for UE A that performs relatively low-priority communication. In this allocation, the radio resources for the downlink channels (MPDCCH (MTC Physical Downlink Control Channel) and PDSCH (Physical Downlink Shared Channel)) for UE A are divided into 4 subframes and 8 subframes corresponding to the number of repetitions. Only prepared. Then, it is assumed that a request for transmission of high-priority traffic to be transmitted to UE B occurs during transmission of the downlink data (for example, the second subframe of the MPDCCH). In this case, conventionally, radio resources for UE B are not allocated until after data transmission to UE A is completed (for example, 12 subframes after a traffic transmission request is generated). On the other hand, in the present embodiment, since the communication with UE B takes priority over the communication with UE A, the radio resources allocated for communication with UE A are allocated to the communication with UE B. Used for FIG. 2B shows a state in which a channel for communication with UE B has been allocated from the next subframe in which a traffic transmission request has occurred. Here, an example is shown in which two and four subframes are allocated as MPDCCH and PDSCH for communication with UE B, respectively. According to such allocation, it is possible to improve the probability that radio resources can be allocated immediately after a transmission request occurs for traffic with a high priority.

  Note that, when performing such radio resource allocation, the base station apparatus 101 transmits the uplink signal to the UE A in the radio resource allocated to the UE A for transmitting the uplink signal. The radio resource allocation is adjusted so as to prevent the transmission of the radio resource. That is, UE A operates to return an HARQ response in the uplink according to the once allocated radio resource as shown in FIG. 2A, for example, and cannot change this. Therefore, when the base station apparatus 101 allocates a radio resource such that an uplink signal such as a HARQ response is received from the UE B at the same timing, the uplink signals interfere with each other. For this reason, the base station apparatus 101 allocates radio resources to UE B so as to prevent such interference from occurring. For example, when allocation as shown in FIG. 2 (A) is performed, the number of repetitive transmissions of the Physical Uplink Control Channel (MPDCCH), PDSCH, and PUCCH (UE) with UE B is 2, 4, and 4, respectively. If the number of times is less than or equal to the number of times, radio resources are allocated as shown in FIG. On the other hand, if the number of repetitive transmissions of any of the MPDCCH, PDSCH, and PUCCH is greater than the above number, the base station apparatus 101 receives the uplink signal at the same timing. Therefore, it is not possible to allocate the radio resources as shown in FIG. For this reason, the base station apparatus 101 can start allocating radio resources for UE B at a predetermined timing such that the uplink signal is not received at the same timing as in FIG. 2C, for example. FIG. 2C shows an example in which the number of repeated transmissions of the MPDCCH and the PDSCH is four and eight, respectively. In this case, when the transmission of the MPDCCH is started from the next subframe in which the traffic transmission request has occurred, the timing of the transmission of the PUCCH by UE A and the transmission of the PUCCH of UE B coincide with each other, and interference on the uplink occurs. Will happen. Therefore, the base station apparatus 101 delays the transmission start timing of the MPDCCH so that the transmission timing of the PUCCH of UE B is after the end of the transmission period of the PUCCH of UE A.

  In addition, the base station apparatus 101 allocates radio resources as described above for transmission of a downlink signal (MPDCCH) for allocating radio resources for transmitting a data signal to UE B as described above. Can do it. That is, the base station apparatus 101 transmits the MPDCCH so that the PUSCH (Physical Uplink Shared Channel) transmitted from the UE B is transmitted at a timing that does not interfere with the PUCCH transmitted by the UE A. For example, when the number of repeated transmissions of the MPDCCH in the communication with UE B is X, the number of repeated transmissions of the PUSCH is Y, and the number of subframes from the end of the transmission of the MPDCCH to the transmission of the PUSCH is C, If the MPDCCH is transmitted immediately after the occurrence, the transmission timing of the PUSCH is from the X + C + 1 subframe to the X + C + Y subframe. For this reason, when transmission of PUCCH by UE A is not performed during transmission of these Y subframes, base station apparatus 101 assigns downlink to UE A immediately after traffic occurs. Is determined to be used for transmission of the MPDCCH. On the other hand, if the transmission of the PUCCH by UE A is performed during the transmission of these Y subframes, the base station apparatus 101 sets the PUSCH of UE B at the timing after the transmission of the PUCCH of UE A is completed. The transmission timing of the MPDCCH is delayed so as to be transmitted. As a result, it is possible to early execute communication to be prioritized while preventing occurrence of interference in the uplink.

  Note that, in the above example, the base station apparatus 101 uses the downlink radio resource allocated to UE A so that the base station apparatus 101 does not receive the PUCCH or PUSCH of UE B at the same timing as the PUCCH of UE A. However, the present invention is not limited to this. That is, also for the PUSCH of UE A, similarly to the PUCCH, the uplink of UE B is not used at the same timing. That is, allocation of the fourth radio resource for UE B such that the uplink communication of UE B is not performed in the third radio resource allocated for all uplink communication of UE A. Is performed.

  In addition, for example, when a plurality of radio resources are allocated for uplink signals such as PUCCH and PUSCH of UE A, when the base station apparatus 101 receives signals for only some radio resources, When the reception of the uplink signal is successful, it can be determined that there is no problem even if the uplink signal receives interference. For this reason, when the base station apparatus 101 successfully receives the signal in a part of the radio resources allocated to the uplink signal for the UE A, the uplink signal for the UE B in the remaining part. Radio resources can be allocated while allowing transmission. FIG. 3 shows an example of radio resource allocation at this time. In this example, as shown in FIG. 3A, after the MPDCCH for allocating the uplink radio resource to UE A is repeatedly transmitted four times, the PUSCH from UE A is repeatedly transmitted sixteen times. An example of the case is shown. Here, it is assumed that, at the time of the second transmission of the MPDCCH, a request to transmit the traffic of UE B has occurred, as in the example of FIG. In this case, as long as the signal of UE B is repeatedly transmitted, a radio resource cannot be allocated for UE B immediately after the occurrence of a traffic transmission request. On the other hand, for example, it is assumed that the base station apparatus 101 succeeds in receiving the uplink signal (PUSCH) from UE A repeatedly transmitted 16 times for the third time. In this case, it can be said that there is no problem even if interference is given to the uplink signal from UE A transmitted from the fourth time. For this reason, the base station apparatus 101 determines that the reception of the uplink signal from the UE A is successful, and thereafter, even during the uplink signal transmission period of the UE A, the base station apparatus 101 transmits the signal from the UE B. Radio resources can be allocated by allowing the occurrence of an uplink signal. FIG. 3 (B) is an example in which a radio resource for transmitting an uplink signal (PUSCH) is allocated to UE B. After the uplink signal of UE A is successfully received, the radio resource for PUSCH is allocated. A downlink control signal (PDSCH) for notifying the assignment is transmitted. FIG. 3C is an example in which a radio resource for transmitting a downlink signal (PDSCH) is allocated to UE B and a radio resource for transmitting a PUCCH is transmitted as a response signal. By doing so, even when the uplink radio resources are allocated to UE A performing low-priority communication for a long period of time, from the time when the signal from UE A is successfully received, Since it is possible to allocate a radio resource allowing interference to a signal from the UE A, it is possible to quickly allocate a radio resource to the UE B performing high-priority communication.

  In this case, the uplink signal transmitted by UE B interferes with the uplink signal transmitted by UE A, but similarly, the uplink signal transmitted by UE A with respect to the uplink signal transmitted by UE B Signals interfere. For this reason, when the base station apparatus 101 receives a signal from UE B at the same timing as the signal of UE A, the base station apparatus 101 considers the influence of the signal from UE A in order to accurately receive the uplink signal of UE B. It needs to be suppressed. At this point, the base station apparatus 101 has successfully received the signal from the UE A, and can treat the signal as a known signal. For this reason, the base station apparatus 101 cancels the signal of UE A which is an interference component with respect to the signal of UE B by signal processing such as subtracting the replica of the signal of UE A from the received signal, and Can be received accurately. In the example of FIG. 3B, at the timing of receiving the PUSCH from UE B, the base station apparatus 101 removes the component of the signal that has already been successfully received from UE A from the received signal by signal processing. , UE B can be accurately received. Similarly, in the example of FIG. 3C, at the timing of receiving the PUCCH from UE B, base station apparatus 101 removes the signal component from UE A that has already been successfully received from the received signal by signal processing. Thus, it is possible to correctly receive the PUCCH from UE B. According to this, after the success of the uplink signal from the lower priority UE A, the influence of interference is reduced for the uplink signal from the UE B received at the same timing as the uplink signal, and The probability of success can be improved.

  The base station device 101 does not transmit a signal addressed to UE A while using the radio resource for performing communication with UE B. At this time, since UE A recognizes that the state of the radio resource allocated to the own device is, for example, as shown in FIG. 2A, the data addressed to UE B is transmitted using the radio resource. Then, at least in the radio resource, data reception fails. However, for example, since data for UE A is transmitted in the first two subframes of the MPDCCH and the last four subframes of the PDSCH in FIG. 2B, UE A receives In some cases, the signal can be successfully received. On the other hand, when the radio resources that can be used for the communication of the UE A become extremely small due to the allocation of the radio resources to the UE B, the probability of the successful communication of the UE A becomes very low. For this reason, the base station apparatus 101 estimates the degree of deterioration of the communication quality of UE A due to, for example, allocation of radio resources to UE B, and according to the degree, uses radio resources that are not allocated to UE B. A determination may be made whether to transmit a signal to UE A. That is, for example, when the radio resources available to UE A decrease significantly due to the allocation of radio resources to UE B, base station apparatus 101 estimates that the degradation of communication quality is large, Signals addressed to A may not be transmitted. This makes it possible to suppress interference with other signals due to unnecessary transmission of a signal that UE A is expected to be unable to successfully receive. At this time, the base station apparatus 101 may use the unused radio resource for communication with, for example, the third terminal apparatus. As a result, the frequency use efficiency of the entire system can be improved.

  Note that, when a traffic transmission request of UE B occurs, the base station apparatus 101 determines whether communication with UE B should be given priority over communication with UE A, and UE B has priority. If it is determined that the processing should be performed, the above-described processing can be executed. In addition, the base station apparatus 101 communicates with UE A in at least one of the case where the communication with UE B is an emergency call, the case of real-time communication, and the case where the allowable delay is exceeded. It can be determined that the communication should be prioritized. Note that the base station apparatus 101 communicates with UE B in at least one of the case where the communication with UE A is an emergency call, the case of real-time communication, and the case where the allowable delay is exceeded. Is an emergency call, real-time communication, and / or exceeds the allowable delay, it is not necessary to determine that UE B has priority.

  In addition, the base station apparatus 101 does not need to execute the above-described processing when repetitive transmission is not used in communication with UE A or when the number of repetitive transmissions is equal to or less than a predetermined number. In such a case, even if the communication of UE B is not interrupted as described above, the period until a communication opportunity is given to UE B can be sufficiently reduced. In such a case, by preventing the communication with the UE B from being interrupted, it is possible to prevent the communication with the UE A from failing and restarting the communication.

(Device configuration)
Next, a configuration example of the base station apparatus 101 that performs the above-described processing will be described with reference to FIG. The base station device 101 includes, for example, a processor 401, a ROM 402, a RAM 403, a storage device 404, and a communication circuit 405. The processor 401 is a computer including one or more processing circuits, such as a general-purpose CPU (central processing unit) and an ASIC (application-specific integrated circuit), and is stored in the ROM 402 and the storage device 404. By reading and executing the stored program, the entire process of the base station apparatus 101 and the above-described processes are executed. The ROM 402 is a read-only memory that stores a program relating to processing executed by the base station apparatus 101 and information such as various parameters. The RAM 403 functions as a work space when the processor 401 executes a program, and is a random access memory that stores temporary information. The storage device 404 includes, for example, a removable external storage device or the like. The communication circuit 405 includes, for example, a circuit for wired communication or wireless communication. The base station apparatus 101 is configured to include, for example, a baseband circuit, an RF circuit, and the like for each of MTC and LTE, and an antenna, as a communication circuit 405 for communication with UE A and UE B. Further, the communication circuit 405 of the base station device 101 may include, for example, a circuit for performing (wired or wireless) communication with another base station device or a network node. Although one communication circuit 405 is illustrated in FIG. 4, the base station device 101 may include a plurality of communication circuits.

  FIG. 5 shows a functional configuration example of the base station apparatus 101. The base station apparatus 101 includes, for example, a communication unit 501 and a communication control unit 502. In addition, the communication control unit 502 includes, for example, a resource allocation unit 503, a priority determination unit 504, and an interference removal unit 505.

  The communication unit 501 is a functional unit for performing communication with UE A and UE B. The communication control unit 502 controls communication by the communication unit 501. For example, the communication control unit 502 determines the number of repetitive transmissions in communication with UE A or UE B and allocates radio resources, and performs communication with each UE using the radio resources allocated to the UE. The communication unit 501 is controlled to perform the operation.

  The resource assignment unit 503 assigns frequency / time radio resources to UEs located in the cell where the base station apparatus 101 is deployed, in consideration of repetitive transmission when using the CE mode. Further, when the resource allocating unit 503 allocates temporally continuous radio resources for low-priority communication with the first UE, high-priority communication with the second UE is requested. In this case, the communication unit 501 is controlled so as to perform communication with the second UE without performing communication with the first UE in at least a part of the allocated wireless resources. That is, radio resource allocation control is performed so that high-priority communication is interrupted by low-priority communication. Also, at this time, the resource allocation unit 503 prevents the second UE from transmitting an uplink signal in the radio resources allocated for the uplink communication of the first UE, or Only when the uplink communication of the second UE succeeds, the radio resource is allocated so as to allow the uplink communication of the second UE in the radio resource. Since a specific example of the process is as described above, the description here is omitted.

  When a traffic transmission request is issued for the second UE, the priority determination unit 504 performs communication with the first UE to which radio resources have already been allocated at that time, and communication with the second UE. It is determined which of the communications between the two should be given priority. When the priority determination unit 504 determines that the communication with the second UE should be given priority, the resource allocation unit 503 switches the communication of the second UE to the communication of the first UE as described above. Execute processing such as interrupting. On the other hand, when the priority determination unit 504 determines that communication with the first UE should be given priority, the resource allocation unit 503 interrupts communication with the second UE to communication with the first UE. Instead, the radio resource control is performed so that communication with the second UE is performed after communication with the first UE.

  The interference removing unit 505 performs the second radio resource allocation when the resource allocation unit 503 performs radio resource allocation such that the uplink signal of the first UE and the uplink sync signal of the second UE are simultaneously received. In order to improve the reception accuracy of the signal of the UE, the uplink signal of the first UE is removed as an interference component. When the uplink signal of the first UE and the uplink sync signal of the second UE are received simultaneously, the interference canceling unit 505 succeeds in receiving the uplink signal of the first UE. For example, a replica signal is generated using data in the signal that has been successfully received, and is removed from the received signal. More specifically, data in the signal of the first UE is subjected to error correction coding and modulation performed by UE A when transmitting a signal including the data, and the signal after the processing is applied to the signal. On the other hand, a replica of an uplink signal from the first UE is generated by multiplying by a transmission channel estimation value regarding a transmission channel from the first UE to the base station apparatus 101. Then, by subtracting this from the received signal, the component of the uplink signal from the first UE is removed from the received signal. For this reason, the influence of the interference of the uplink signal from the first UE on the uplink signal from the second UE can be reduced.

(Processing flow)
Finally, the flow of the processing executed by the above-described base station apparatus 101 will be schematically summarized. FIG. 6 is a diagram schematically illustrating a flow of processing executed by base station apparatus 101. When a new traffic transmission request is generated (YES in S601), base station apparatus 101 executes the following processing. If there is no such request (NO in S601), the remaining processing in FIG. 6 is not performed. The base station apparatus 101 determines whether there is a UE to which a radio resource has already been allocated when a new traffic transmission request occurs (S602). When there is no UE to which the radio resource has been allocated (NO in S602), the base station apparatus 101 only needs to allocate the radio resource in the same manner as the conventional traffic for the new traffic that has occurred. finish. On the other hand, when there is a UE to which a radio resource has been allocated (YES in S602), the base station apparatus 101 compares the priorities of the communication of the allocated UE and the communication of the new traffic (S603). Then, when the base station apparatus 101 determines that the priority of the communication of the new traffic is lower (NO in S603), the base station apparatus 101 does not interrupt the new traffic and terminates the communication of the allocated UE. In order to perform communication by allocating radio resources, the process ends. On the other hand, when it is determined that the priority of the communication of the new traffic is higher (YES in S603), the base station apparatus 101 executes the communication of the newly generated traffic by using the allocated radio resources ( S604). That is, the communication of the newly generated traffic is interrupted with respect to the communication to which the radio resources are already allocated. The details of each of the above processes are as described above, and thus will not be repeated here.

  It should be noted that the base station apparatus 101 can perform predetermined calls such as when the newly generated traffic has a higher priority, an emergency call or real-time communication, or a case where the traffic exceeds the allowable delay of the traffic. As long as the conditions are not satisfied, interrupts may not be permitted.

  By such processing, it is possible to prevent a state in which high-priority communication cannot be executed due to incomplete completion of low-priority communication, or to prevent the state from being prolonged. .
