本公开主张在2020年9月22日在中国提交的中国专利申请号No.202010998697.1的优先权,其全部内容通过引用包含于此。The present disclosure claims priority to Chinese Patent Application No. 202010998697.1 filed in China on Sep. 22, 2020, the entire contents of which are incorporated herein by reference.
本公开涉及移动通信技术领域,具体涉及一种物理上行共享信道的传输方法、接收方法、终端及基站。The present disclosure relates to the field of mobile communication technologies, and in particular, to a transmission method, a reception method, a terminal and a base station of a physical uplink shared channel.
在相关技术中,物理上行共享信道(Physical Uplink Shared Channel,PUSCH)调度方式中,通过下行控制信息(Downlink Control Information,DCI)指示PUSCH的时域资源信息,具体包括时隙偏移量K2(slot offset K2),起始符号(Start symbol)和长度(length),如图1所示。DCI指示了混合自动重传请求进程号(HARQ process number)和新数据指示(New data indication),当HARQ进程号相同且NDI未翻转时表示调度的是重传数据。另外,通过无线资源控制(Radio Resource Control,RRC)信令配置PUSCH的重复次数pusch-AggregationFactor(2,4,8),或者在DCI指示PUSCH时域资源信息时,指示重复次数numberofrepetitions。另外,通过DCI指示PUSCH的冗余版本(Redundancy version,RV)模式,具体值可以是以下任意一种:0231,2310,3102,1023。例如,图1中的RV为“0231”,表示4个相邻的PUSCH的冗余版本模式分别是RV0、RV2、RV3和RV1,“2310”等的含义也类似。In the related art, in the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) scheduling mode, the time domain resource information of the PUSCH is indicated by downlink control information (Downlink Control Information, DCI), specifically including the time slot offset K2 (slot offset K2), start symbol (Start symbol) and length (length), as shown in Figure 1. DCI indicates the hybrid automatic repeat request process number (HARQ process number) and the new data indication (New data indication). When the HARQ process number is the same and the NDI is not reversed, it means that retransmission data is scheduled. In addition, the number of repetitions of PUSCH pusch-AggregationFactor (2, 4, 8) is configured through radio resource control (Radio Resource Control, RRC) signaling, or when the DCI indicates PUSCH time domain resource information, the number of repetitions is indicated. In addition, a redundancy version (Redundancy version, RV) mode of the PUSCH is indicated through the DCI, and the specific value may be any of the following: 0231, 2310, 3102, and 1023. For example, the RV in FIG. 1 is "0231", indicating that the redundancy version modes of four adjacent PUSCHs are RV0, RV2, RV3, and RV1, respectively, and the meaning of "2310" is similar.
相关技术在进行PUSCH顺序调度时,如果HARQ进程号相同,则前一个PUSCH传输之后才能再发DCI调度相同HARQ进程号的PUSCH。图2给出了上述调度的一个示例,其中DCI-0和DCI-1均调度HARQ进程号为1的PUSCH,在DCI-0所调度的PUSCH传输之后才发送调度同一个HARQ进程号的下一个PUSCH的DCI-1。In the related art, when PUSCH sequential scheduling is performed, if the HARQ process numbers are the same, the DCI can only be sent after the previous PUSCH transmission to schedule the PUSCH with the same HARQ process number. Figure 2 shows an example of the above scheduling, in which both DCI-0 and DCI-1 schedule the PUSCH with the HARQ process number 1, and the next one that schedules the same HARQ process number is sent after the PUSCH transmission scheduled by DCI-0. DCI-1 for PUSCH.
PUSCH功率控制中发射功率控制(Transmit Power Control,TPC)命令 的配置方式为:通过DCI中指示的TPC命令(TPC command)来确定PUSCH的闭环功率控制调整量。其中,DCI 0_0/DCI 0_1可以指示TPC command。DCI 2_2可以指示TPC组命令(group common TPC),其中,包括多个块号码(block),如block number 1,block number 2,…,block number N,每个block number包含3比特,分别为1比特的closeloop和2比特的TPC,另外还通过RRC配置tpc-Index指示第几个block是用于接收此DCI的。当终端(UE)收到多个DCI指示TPC时,UE在发送PUSCH时会将收到的多个DCI中TPC指示的值求和并应用于PUSCH的闭环功率控制。The configuration mode of the transmit power control (Transmit Power Control, TPC) command in the PUSCH power control is: determine the closed-loop power control adjustment amount of the PUSCH through the TPC command (TPC command) indicated in the DCI. Among them, DCI 0_0/DCI 0_1 can indicate TPC command. DCI 2_2 can indicate a TPC group command (group common TPC), which includes multiple block numbers (block), such as block number 1, block number 2, ..., block number N, each block number contains 3 bits, which are 1 respectively Bit of closeloop and 2-bit TPC, in addition, the RRC configuration tpc-Index indicates which block is used to receive this DCI. When a terminal (UE) receives multiple DCIs indicating TPCs, the UE will sum the values indicated by the TPCs in the multiple received DCIs and apply them to the closed-loop power control of the PUSCH when sending the PUSCH.
如图3所示,在多发送接收节点(Multi-TRP)场景下,2个TRP的控制资源集(Control Resource Set,CORESET)关联不同的控制资源集池索引(coresetPoolIndex),终端通过判断CORESET所关联的coresetPoolIndex,即可判断CORESET上承载的PDCCH是来自哪个TRP。As shown in Figure 3, in the Multi-TRP scenario, the control resource sets (Control Resource Set, CORESET) of the two TRPs are associated with different control resource set pool indices (coresetPoolIndex), and the terminal determines the CORESET by judging the The associated coresetPoolIndex can determine which TRP the PDCCH carried on the CORESET comes from.
例如,TRP0关联coresetPoolIndex=0,TRP1关联coresetPoolIndex=1。终端发送1个PUSCH,2个TRP均可以接收。For example, TRP0 is associated with coresetPoolIndex=0, and TRP1 is associated with coresetPoolIndex=1. The terminal sends one PUSCH, and both TRPs can be received.
为了提升Multi-TRP场景PUSCH可靠性,考虑引入PUSCH重复传输(PUSCH repetition)。目前,相关技术中的重复传输方案对于Multi-TRP场景下的PUSCH重复传输并没有具体的实现方案。In order to improve the reliability of PUSCH in Multi-TRP scenarios, consider introducing PUSCH repetition transmission (PUSCH repetition). At present, the repeated transmission scheme in the related art does not have a specific implementation scheme for the repeated transmission of the PUSCH in the Multi-TRP scenario.

基站可在基站控制器的控制下与终端11通信,在各种示例中,基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中,这些基站中的一些可以通过回程链路直接或间接地彼此通信,回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如,每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如,参考信号、控制信道等)、开销信息、数据等。The base stations may communicate with the terminal 11 under the control of a base station controller, which in various examples may be part of a core network or some base station.

如背景技术中所述的,相关技术对于Multi-TRP场景下的PUSCH重复传输并没有具体的实现方案。例如,关于如何通过2个不同的DCI调度1个PUSCH进行重复传输,以及PUSCH重复传输时的冗余版本(Redundancy version,RV)模式、传输时域位置、功率控制参数如何确定都没有具体说明。As described in the background art, the related art does not have a specific implementation solution for PUSCH repeated transmission in a Multi-TRP scenario. For example, there is no specific description on how to schedule one PUSCH through two different DCIs for repeated transmission, and how to determine the redundancy version (Redundancy version, RV) mode, transmission time domain position, and power control parameters when the PUSCH is repeatedly transmitted.
为了解决以上问题中的至少一种,本公开实施例提供了一种物理上行共享信道(PUSCH)的传输方法,实现了2个TRP的PUSCH信道的重复传输,另外,本公开实施例还对PUSCH重复传输时的RV模式、传输时域位置、功率控制参数提供了具体实现方案。In order to solve at least one of the above problems, the embodiments of the present disclosure provide a method for transmitting a physical uplink shared channel (PUSCH), which realizes the repeated transmission of the PUSCH channels of two TRPs. The RV mode, transmission time domain position, and power control parameters during repeated transmission provide specific implementation solutions.
请参照图5,本公开实施例提供的物理上行共享信道的传输方法,在应用于终端侧时,包括:Referring to FIG. 5 , the method for transmitting the physical uplink shared channel provided by the embodiment of the present disclosure, when applied to the terminal side, includes:
步骤51,终端将第一DCI和第二DCI调度的PUSCH进行重复传输。 Step 51, the terminal repeatedly transmits the PUSCH scheduled by the first DCI and the second DCI.
这里,所述第一DCI和第二DCI指示的第一参数均相同,所述第一参数包括冗余版本模式、HARQ进程号和新数据指示中的至少一种。Here, the first parameters indicated by the first DCI and the second DCI are the same, and the first parameters include at least one of a redundancy version mode, a HARQ process number, and a new data indication.
通过以上步骤,本公开实施例将第一DCI和第二DCI调度的PUSCH进行重复传输,实现了2个TRP的PUSCH信道的重复传输。Through the above steps, the embodiment of the present disclosure repeatedly transmits the PUSCH scheduled by the first DCI and the second DCI, and realizes the repeated transmission of the PUSCH channels of two TRPs.
在上述步骤51之前,终端还可以接收第一DCI,以及接收第二DCI。Before the above step 51, the terminal may also receive the first DCI and receive the second DCI.
优选的,承载所述第一DCI和第二DCI的CORESET各自关联的高层参数控制资源集池索引不同。也就是说,上述第一DCI和第二DCI关联了不同控制资源集池索引(coresetPoolIndex)。Preferably, the high-level parameter control resource set pool indices associated with the CORESETs carrying the first DCI and the second DCI are different. That is to say, the first DCI and the second DCI are associated with different control resource set pool indices (coresetPoolIndex).
具体的,本公开实施例可以将所述第一DCI和第二DCI调度的PUSCH传输时机作为一个集合,然后,确定所述集合中的每个PUSCH传输时机对应的冗余版本。进一步的,还可以根据所确定每个PUSCH传输时机对应的冗余版本,在每个PUSCH传输时机上进行所述PUSCH的重复传输。Specifically, in the embodiment of the present disclosure, the PUSCH transmission occasions scheduled by the first DCI and the second DCI may be regarded as a set, and then the redundancy version corresponding to each PUSCH transmission occasion in the set is determined. Further, according to the determined redundancy version corresponding to each PUSCH transmission occasion, repeated transmission of the PUSCH may be performed on each PUSCH transmission occasion.
在确定某个PUSCH传输时机对应的冗余版本时,具体是根据该PUSCH传输时机在所述集合中的位置,从冗余版本模式中确定出该PUSCH传输时机对应的冗余版本。这里,所述冗余版本模式是第一DCI或第二DCI中指示的,优选的,本公开实施例的所述第一DCI和第二DCI指示的冗余版本模式相同。When determining the redundancy version corresponding to a certain PUSCH transmission occasion, specifically according to the position of the PUSCH transmission occasion in the set, the redundancy version corresponding to the PUSCH transmission occasion is determined from the redundancy version mode. Here, the redundancy version mode is indicated in the first DCI or the second DCI. Preferably, the redundancy version modes indicated by the first DCI and the second DCI in the embodiment of the present disclosure are the same.
