第一方面,在相关技术中,支持两个天线面板同时接收PDSCH,该同时接收物理下行共享信道(Physical Downlink Shared Channel,PDSCH)的接收方案包括:空分复用(Space Division Multiplexing,SDM)、频分复用(Frequency Division Multiplexing,FDM)(包括FDM-A和FDM-B),以及针对高铁场景提出的单频网络(Single Frequency Network,SFN)。First, in related technologies, two antenna panels are supported to receive PDSCH at the same time. The receiving solutions for receiving the Physical Downlink Shared Channel (PDSCH) at the same time include: Space Division Multiplexing (SDM), Frequency Division Multiplexing (FDM) (including FDM-A and FDM-B), and the Single Frequency Network (SFN) proposed for high-speed rail scenarios.
一、对于SDM1. For SDM
在高层信令没有配置SFN方案的情况下,如果下行控制信息(Downlink Control Information,DCI)格式(format)为1-1或者1-2的DCI信令中携带两个传输配置指示(Transmission Configuration Indicator,TCI)状态(states),并且解调参考信号(Demodulation Reference Signal,DMRS)端口(ports)指示包含了两个码分复用(Code Division Multiplexing,CDM)组,则终端认为采用SDM传输方案同时接收PDSCH。这种方案下,PDSCH占用一个传输块(Transport Block,TB)(其也可以称之为“传输数据块”),且是一个冗余版本(Redundant version,RV)的信道编码版本。其中,TB块的大小计算是基于来自两个发送接收节点(Transmission Reception Point,TRP)的所有传输层(layers)获得,且不同TRP的DMRS ports采用不同的CDM组。When the high-level signaling does not configure the SFN solution, if the downlink control information (DCI) format is 1-1 or 1-2, the DCI signaling carries two transmission configuration indicators (Transmission Configuration Indicator). , TCI) states, and the demodulation reference signal (Demodulation Reference Signal, DMRS) port indication contains two code division multiplexing (Code Division Multiplexing, CDM) groups, then the terminal considers that the SDM transmission scheme is used at the same time Receive PDSCH. Under this scheme, PDSCH occupies a Transport Block (TB) (which can also be called a "Transport Data Block"), and is a redundant version (Redundant version, RV) channel coding version. Among them, the calculation of the TB block size is based on all transmission layers (layers) from the two sending and receiving nodes (Transmission Reception Point, TRP), and the DMRS ports of different TRPs use different CDM groups.
二、对于FDM-A2. For FDM-A
当高层信令配置了FDM-A方案的情况下,如果DCI format 1-1或者1-2的DCI信令中携带两个TCI states,并且DMRS ports指示包含了1个CDM组,则终端认为采用FDM-A传输方案同时接收PDSCH。其中,当预编码粒度:预编码资源块组(Precoding Resource Block Group,PRG)配置信息是宽带(wideband),则DCI中携带的频域信息指示频域资源分配(Frequency Domain Resource Allocation,FDRA)中指示的频域资源分成两部分,第一部分关联第一个TCI state,且来自TRP1;第二部分关联第二个TCI state,且来自TRP2。When the FDM-A solution is configured for high-level signaling, if the DCI signaling of DCI format 1-1 or 1-2 carries two TCI states, and the DMRS ports indication contains 1 CDM group, the terminal considers it to be adopted The FDM-A transmission scheme receives PDSCH simultaneously. Among them, when the precoding granularity: Precoding Resource Block Group (PRG) configuration information is wideband, the frequency domain information carried in the DCI indicates the frequency domain resource allocation (Frequency Domain Resource Allocation, FDRA). The indicated frequency domain resource is divided into two parts. The first part is associated with the first TCI state and comes from TRP1; the second part is associated with the second TCI state and comes from TRP2.
PDSCH占用1个TB,TB块大小计算基于整个FDRA指示的频域资源。信道编码RV配置1个,编码后的bit信息分成两部分,并分别映射到不同的TRP上。
PDSCH occupies 1 TB, and the TB block size calculation is based on the frequency domain resources indicated by the entire FDRA. One channel coding RV is configured, and the coded bit information is divided into two parts and mapped to different TRPs respectively.
三、对于FDM-B3. For FDM-B
FDM-B与FDM-A的方案基本相同,不同之处在于:在FDM-B中,两个相同的TB块基于配置的两个RV冗余版本分别做速率匹配(即采用两个RV冗余版本对相同的TB做两次速率匹配),然后分别映射到不同的TRP上。The solutions of FDM-B and FDM-A are basically the same. The difference is that in FDM-B, two identical TB blocks are rate matched based on the two configured RV redundant versions (that is, two RV redundant versions are used). The version performs rate matching on the same TB twice), and then maps them to different TRPs respectively.
四、对于SFN4. For SFN
一个TB块做一次信道编码和速率匹配,然后分别复制到两个TRP上。两个TRP发送相同的PDSCH(包括DMRS)信号,每层数据流同时关联两个不同的TCI states。其中,DMRS Ports指示可以在相同或者不同的CDM组内。One TB block performs channel coding and rate matching once, and then copies it to two TRPs respectively. The two TRPs send the same PDSCH (including DMRS) signal, and each layer of data flow is associated with two different TCI states at the same time. Among them, the DMRS Ports indication can be in the same or different CDM group.
第二方面,在相关技术中,支持上行PUSCH在两个天线面板(panel)之间轮流切换发送,具体的,高层为终端配置两个探测参考信号(Sounding Reference Signal,SRS)资源集合,每个SRS资源集合可以看做是关联一个天线面板(panel)。当PUSCH工作在码本(codebook)模式下,DCI format 0-1 or 0-2的DCI信令中会携带两个发射预编码矩阵指示(Transmitted Precoding Matrix Indicator,TPMI)域,并且传输数据流的信息在第一个TPMI域上。当PUSCH工作在非码本(non-codebook)模式下,DCI format 0-1 or 0-2的DCI信令中会携带两个SRS资源指示(SRS Resource Indicator,SRI)域,并且传输数据流的信息在第一个SRI域上。Secondly, in related technologies, uplink PUSCH is supported to be switched and transmitted between two antenna panels (panel) in turn. Specifically, the upper layer configures two sounding reference signal (Sounding Reference Signal, SRS) resource sets for the terminal. Each The SRS resource set can be regarded as associated with an antenna panel. When PUSCH works in codebook mode, the DCI signaling of DCI format 0-1 or 0-2 will carry two Transmitted Precoding Matrix Indicator (TPMI) fields, and transmit the data stream The information is on the first TPMI field. When PUSCH works in non-codebook mode, the DCI signaling of DCI format 0-1 or 0-2 will carry two SRS Resource Indicator (SRI) fields, and the transmission data stream The information is on the first SRI field.
而本申请实施例是提出上行PUSCH在multi-panel下同时发送的方案,以及提出该方案下相关的SRS资源集合信令如何配置,TPMI/RI域以及SRI域如何指示,DMRS导频和相位跟踪参考信号(Phase Tracking Reference Signals,PTRS)导频的相关影响,以及不同发送方案下频域资源分配的一些调度限制行为等。The embodiment of this application proposes a solution for transmitting uplink PUSCH simultaneously under multi-panel, and proposes how to configure related SRS resource set signaling under this solution, how to indicate the TPMI/RI domain and SRI domain, DMRS pilot and phase tracking Related impacts of reference signal (Phase Tracking Reference Signals, PTRS) pilots, and some scheduling restrictions on frequency domain resource allocation under different transmission schemes.

本实施方式中,终端可以根据调度所述目标PUSCH的第一DCI信令中动态指示的所述目标PUSCH占用的DMRS CDM组的数量或者根据高层为所述目标PUSCH配置的TB的个数,判断所述目标PUSCH传输方案是SDM或者非SDM传输方案。In this embodiment, the terminal can determine based on the number of DMRS CDM groups occupied by the target PUSCH dynamically indicated in the first DCI signaling for scheduling the target PUSCH or according to the number of TBs configured by the higher layer for the target PUSCH.

义重复次数(当PUSCH mapping type被网络信令配置为‘TypeB’时)等于1,则终端选择其中一种所述目标传输方案发送PUSCH;当TDRA指示重复次数大于1,则终端执行Rel-17支持的时分PUSCH重复发送。In the embodiment, when the time domain resource allocation indication field (Time Domain Resource Allocation, TDRA) in DCI format 0-1 or 0-2 indicates the number of repeated transmissions between timeslots (when the PUSCH mapping type (mapping type) is determined by the network When the signaling configuration is 'TypeA') or the time dimension name If the number of repetitions (when the PUSCH mapping type is configured as 'TypeB' by network signaling) is equal to 1, the terminal selects one of the target transmission schemes to send PUSCH; when the TDRA indicates that the number of repetitions is greater than 1, the terminal executes Rel-17 Supported time-division PUSCH repeated transmission.
作为一种可选地实施方式,在调度PDSCH的第二DCI信令中指示N个传输配置指示TCI状态,或者,所述第二DCI信令中指示N个TCI状态组的情况下,所述N个SRS资源集合与所述N个TCI状态或N个TCI状态组一一对应。As an optional implementation manner, in the second DCI signaling that schedules PDSCH, N transmission configurations are indicated to indicate TCI states, or when N TCI state groups are indicated in the second DCI signaling, the N SRS resource sets correspond one-to-one to the N TCI states or N TCI state groups.
在实施中,SRS资源集合中的一个或者多个SRS资源的空间关系与对应的TCI状态或TCI状态组关联。以N等于2为例,第一个所述SRS资源集合中一个或者多个SRS资源的空间关系可以与第二DCI信令中指示的第一TCI state或者第一TCI state组关联;第二个所述SRS资源集合中一个或者多个SRS资源的空间关系可以与第二DCI信令中指示的第二TCI state或者第二TCI state组关联。In an implementation, the spatial relationship of one or more SRS resources in the SRS resource set is associated with the corresponding TCI state or TCI state group. Taking N equal to 2 as an example, the spatial relationship of one or more SRS resources in the first SRS resource set can be associated with the first TCI state or the first TCI state group indicated in the second DCI signaling; the second The spatial relationship of one or more SRS resources in the SRS resource set may be associated with the second TCI state or the second TCI state group indicated in the second DCI signaling.
这样,可以根据SRS资源集合与TCI状态或TCI状态组之间的对应关系,确定该SRS资源集合中的SRS资源的空间关系。In this way, the spatial relationship of the SRS resources in the SRS resource set can be determined based on the correspondence between the SRS resource set and the TCI state or TCI state group.
在一种可选地实施方式中,在所述目标PUSCH采用码本的传输模式的情况下,若所述N个SRS资源集合中的目标SRS资源集合包括M个SRS资源,且所述M个SRS资源的空间关系都与所述第二DCI信令中指示的一个TCI状态关联,则调度所述目标PUSCH的第一DCI信令中携带的SRS资源索引指示域的大小与M的取值相关,M为大于或等于1的整数。In an optional implementation, when the target PUSCH adopts the codebook transmission mode, if the target SRS resource set among the N SRS resource sets includes M SRS resources, and the M The spatial relationships of SRS resources are all associated with a TCI state indicated in the second DCI signaling, then the size of the SRS resource index indication field carried in the first DCI signaling for scheduling the target PUSCH is related to the value of M , M is an integer greater than or equal to 1.
在实施中,上述调度所述目标PUSCH的第一DCI信令中携带的SRS资源索引指示域的大小与M的取值相关,可以是M的取值越大,则SRS资源索引指示域越大,以使SRS资源索引指示域能够指示M个SRS资源的索引,例如:假设SRS资源索引指示域的大小为X比特,则其中,表示对A上取整。这样,可以通过第一DCI信令中的SRS资源索引指示域来指示M个SRS资源的空间关系都与所述第二DCI信令中指示的一个TCI状态关联。In implementation, the size of the SRS resource index indication field carried in the first DCI signaling for scheduling the target PUSCH is related to the value of M. The larger the value of M, the larger the SRS resource index indication field. , so that the SRS resource index indication field can indicate the index of M SRS resources. For example: assuming that the size of the SRS resource index indication field is X bits, then in, Indicates rounding A up. In this way, the SRS resource index indication field in the first DCI signaling can be used to indicate that the spatial relationships of the M SRS resources are all associated with one TCI state indicated in the second DCI signaling.
进一步地,在M大于1的情况下,所述目标SRS资源集合中的每个SRS资源对应的端口数不同。这样,对应用于同一个TCI state的多个SRS资源可
以使用不同的端口数进行传输,从而能够在全功率发送模式(full-power mode)和非全功率发送模式之间动态切换。Further, when M is greater than 1, the number of ports corresponding to each SRS resource in the target SRS resource set is different. In this way, multiple SRS resources corresponding to the same TCI state can Different port numbers are used for transmission, allowing dynamic switching between full-power mode and non-full-power mode.
在另一种可选地实施方式中,在所述目标PUSCH采用码本的传输模式的情况下,若所述N个SRS资源集合中的目标SRS资源集合包括M个SRS资源,且所述M个SRS资源的空间关系都与所述第二DCI信令中指示的一个目标TCI状态组中的一个TCI状态关联,则调度所述目标PUSCH的第一DCI信令中携带的SRS资源索引指示域的大小与M’相关,其中,M’表示所述M个SRS资源对应的M个SRS端口中互不相同的SRS端口的数量,且M’为大于或等于1且小于或等于M的整数。In another optional implementation, when the target PUSCH adopts a codebook transmission mode, if the target SRS resource set among the N SRS resource sets includes M SRS resources, and the M The spatial relationship of each SRS resource is associated with a TCI state in a target TCI state group indicated in the second DCI signaling, then the SRS resource index indication field carried in the first DCI signaling of the target PUSCH is scheduled. The size of is related to M', where M' represents the number of mutually different SRS ports among the M SRS ports corresponding to the M SRS resources, and M' is an integer greater than or equal to 1 and less than or equal to M.
在实施中,上述目标SRS资源集合中的M个SRS资源对应有M个SRS端口,该M个SRS端口中可能包括相同的SRS端口,此时,M’可以等于M个SRS端口中互不相同的SRS端口的种类数,例如:假设M等于4,这4个SRS资源对应的SRS端口分别为:4,4,2,1,则M’等于3。In implementation, the M SRS resources in the above target SRS resource set correspond to M SRS ports, and the M SRS ports may include the same SRS port. In this case, M' may be equal to the M SRS ports that are different from each other. The number of types of SRS ports. For example, assuming M is equal to 4, the SRS ports corresponding to these four SRS resources are: 4, 4, 2, and 1 respectively, then M' is equal to 3.
上述调度所述目标PUSCH的第一DCI信令中携带的SRS资源索引指示域的大小与M’相关,可以是M’的取值越大,则SRS资源索引指示域越大,以使SRS资源索引指示域能够指示M’个分别具有不同SRS端口的SRS资源的索引,例如:假设SRS资源索引指示域的大小为X比特,则这样,可以通过第一DCI信令中的SRS资源索引指示域来指示对应其中一种SRS端口的SRS resource。The size of the SRS resource index indication field carried in the first DCI signaling for scheduling the target PUSCH is related to M'. The larger the value of M', the larger the SRS resource index indication field, so that the SRS resource The index indication field can indicate the index of M' SRS resources respectively having different SRS ports. For example: assuming that the size of the SRS resource index indication field is X bits, then In this way, the SRS resource corresponding to one of the SRS ports can be indicated through the SRS resource index indication field in the first DCI signaling.
可选地,在所述M个SRS资源中对应目标SRS端口的SRS资源数量为L个的情况下,所述目标SRS端口对应的L个SRS资源的空间关系分别与所述目标TCI状态组中的前L个TCI状态一一对应关联,L为大于0的整数。Optionally, in the case where the number of SRS resources corresponding to the target SRS port among the M SRS resources is L, the spatial relationship between the L SRS resources corresponding to the target SRS port and the target TCI status group are respectively The first L TCI states are associated in one-to-one correspondence, and L is an integer greater than 0.
在实施中,上述目标SRS端口可以是M个SRS资源对应的任一个SRS端口,目标TCI状态组可以包括K个TCI states,其中,K可以是大于或者等于L的整数,其中,在K等于L的情况下,可以根据目标TCI状态组中的全部TCI状态来确定该L个TCI状态关联的且与某一个SRS端口对应的L个SRS资源的空间关系;在K大于L的情况下,从目标TCI状态组中选择前L个TCI状态,并据此可以确定该L个TCI状态关联的且与某一个SRS端口对应的L个SRS资源的空间关系。
In implementation, the above target SRS port may be any SRS port corresponding to M SRS resources, and the target TCI state group may include K TCI states, where K may be an integer greater than or equal to L, where K equals L In the case of The first L TCI states are selected from the TCI state group, and based on this, the spatial relationship of the L SRS resources associated with the L TCI states and corresponding to a certain SRS port can be determined.

An associated SRS resource;
其中,所述第一关联关系包括所述目标SRS端口对应的L个SRS资源的空间关系与所述L个TCI状态之间的关联关系。Wherein, the first association relationship includes an association relationship between the spatial relationship of L SRS resources corresponding to the target SRS port and the L TCI states.
其中,上述第一关联关系,具体指:所述目标SRS端口对应的L个SRS资源的空间关系分别与所述目标TCI状态组中的前L个TCI状态一一对应关联的关联关系。The above-mentioned first association relationship specifically refers to an association relationship in which the spatial relationships of the L SRS resources corresponding to the target SRS port are respectively associated with the first L TCI states in the target TCI state group in a one-to-one correspondence.
例如:假设N等于4,其中2个SRS资源使用SRS端口A,另外2个SRS资源使用SRS端口B,若SRS端口A对应两个公共波束(unified beam)资源,则根据下行DCI中指示的一个TCI state可以确定两个公共波束资源中的一个作为目标PUSCH传输关联的一个SRS资源。即不同SRS端口可以分组去和unified beam关联,并进一步通过下行DCI中指示的一TCI state来确定将一个unified beam作为目标PUSCH传输关联的一个SRS资源。For example: Suppose N is equal to 4, two of the SRS resources use SRS port A, and the other two SRS resources use SRS port B. If SRS port A corresponds to two common beam (unified beam) resources, according to one indicated in the downlink DCI TCI state can determine one of the two common beam resources as an SRS resource associated with the target PUSCH transmission. That is, different SRS ports can be grouped to associate with unified beams, and further determine a unified beam as an SRS resource associated with the target PUSCH transmission through a TCI state indicated in the downlink DCI.
本实施方式中,在至少两个SRS资源对应某一个SRS端口的情况下,可以联合第二DCI信令中指示的TCI状态所关联的SRS资源来从对应某一个SRS端口的SRS资源中确定所述目标PUSCH传输关联的一个SRS资源。In this embodiment, when at least two SRS resources correspond to a certain SRS port, the SRS resources associated with the TCI status indicated in the second DCI signaling can be combined to determine the SRS resources corresponding to a certain SRS port. An SRS resource associated with the target PUSCH transmission.
作为一种可选地实施方式,在N等于2的情况下,调度所述目标PUSCH的第一DCI信令携带第一指示域和第二指示域;As an optional implementation manner, when N is equal to 2, the first DCI signaling for scheduling the target PUSCH carries the first indication field and the second indication field;
在所述目标PUSCH采用码本的传输模式的情况下,所述第一指示域包括第一个SRS资源集合对应的发射预编码矩阵指示TPMI与秩指示(Rank Indicator,RI)的联合指示域,所述第二指示域包括第二个SRS资源集合对应的TPMI指示域或TPMI与RI的联合指示域,所述N个SRS资源集合包括所述第一个SRS资源集合和所述第二个SRS资源集合;When the target PUSCH adopts the codebook transmission mode, the first indication field includes a joint indication field of the transmit precoding matrix indicator TPMI and the rank indicator (Rank Indicator, RI) corresponding to the first SRS resource set, The second indication field includes a TPMI indication field corresponding to the second SRS resource set or a joint indication field of TPMI and RI, and the N SRS resource sets include the first SRS resource set and the second SRS resource collection;
在所述目标PUSCH采用非码本的传输模式的情况下,所述第一指示域包括所述所述第一个SRS资源集合对应的SRS资源指示SRI与RI的联合指示域,所述第二指示域包括所述第二个SRS资源集合对应的SRI指示域或SRI与RI的联合指示域。
When the target PUSCH adopts a non-codebook transmission mode, the first indication field includes a joint indication field of SRS resource indication SRI and RI corresponding to the first SRS resource set, and the second indication field The indication field includes an SRI indication field corresponding to the second SRS resource set or a joint indication field of SRI and RI.
本实施方式中,在第一DCI信令中划分两个不同的指示域来分别指示第一个SRS资源集合和第二个SRS资源集合在码本传输模式下的TPMI和RI,或者,在第一DCI信令中划分两个不同的指示域来分别指示第一个SRS资源集合和第二个SRS资源集合在非码本传输模式下的SRI和RI。值得注意的是,在实施中可以仅指示第一个SRS资源集合的RI,而不指示第二个SRS资源集合的RI,而第二个SRS资源集合的RI可以基于预设规则来根据第一个SRS资源集合的RI确定。例如:所述第一个指示域包含与所述第一个SRS资源集合关联的PUSCH传输资源的层数据流数或者RI信息;In this embodiment, two different indication fields are divided in the first DCI signaling to respectively indicate the TPMI and RI of the first SRS resource set and the second SRS resource set in the codebook transmission mode, or, in the third Two different indication fields are divided into one DCI signaling to respectively indicate the SRI and RI of the first SRS resource set and the second SRS resource set in the non-codebook transmission mode. It is worth noting that in an implementation, only the RI of the first SRS resource set may be indicated, but not the RI of the second SRS resource set, and the RI of the second SRS resource set may be determined based on the first set of rules based on preset rules. The RI of each SRS resource set is determined. For example: the first indication field contains the number of layer data streams or RI information of the PUSCH transmission resources associated with the first SRS resource set;
其中,与所述第二个SRS资源集合关联的PUSCH传输资源的层(layers)数据流数或者RI信息与所述第一个SRS资源集合关联的PUSCH传输资源的层数据流数或者RI信息相同。Wherein, the number of layers data streams or RI information of the PUSCH transmission resources associated with the second SRS resource set is the same as the number of layers data streams or RI information of the PUSCH transmission resources associated with the first SRS resource set. .
这样,在码本传输模式下,可以在第一指示域中指示第一个SRS资源集合对应的TPMI与RI的联合指示域,而在第二指示域中仅指示第二个SRS资源集合对应的TPMI,且确定第二个SRS资源集合关联的PUSCH传输资源的层数据流数或者RI信息与所述第一个SRS资源集合关联的PUSCH传输资源的层数据流数或者RI信息相同;在非码本传输模式下,可以在第一指示域中指示第一个SRS资源集合对应的SRS资源指示SRI与RI的联合指示域,而在第二指示域中仅指示第二个SRS资源集合对应的SRI,且确定第二个SRS资源集合关联的PUSCH传输资源的层数据流数或者RI信息与所述第一个SRS资源集合关联的PUSCH传输资源的层数据流数或者RI信息相同,这样,可以减少第二指示域的占用比特。In this way, in the codebook transmission mode, the joint indication field of TPMI and RI corresponding to the first SRS resource set can be indicated in the first indication field, while only the TPMI and RI corresponding to the second SRS resource set are indicated in the second indication field. TPMI, and determine that the number of layer data streams or RI information of the PUSCH transmission resources associated with the second SRS resource set is the same as the number of layer data streams or RI information of the PUSCH transmission resources associated with the first SRS resource set; in non-code In this transmission mode, the joint indication field of SRS resource indication SRI and RI corresponding to the first SRS resource set can be indicated in the first indication field, while only the SRI corresponding to the second SRS resource set is indicated in the second indication field. , and it is determined that the number of layer data streams or RI information of the PUSCH transmission resources associated with the second SRS resource set is the same as the number of layer data streams or RI information of the PUSCH transmission resources associated with the first SRS resource set. In this way, it can be reduced The occupied bits of the second indication field.
当然,第一指示域和第二指示域都可以指示TPMI与RI的联合指示域,或者SRI与RI的联合指示域,在此不作具体限定。Of course, both the first indication field and the second indication field may indicate a joint indication field of TPMI and RI, or a joint indication field of SRI and RI, which is not specifically limited here.
作为一种可选地实施方式,所述PUSCH同时发送的方法还包括:As an optional implementation manner, the method of transmitting PUSCH simultaneously also includes:
所述终端接收第一配置信息;The terminal receives first configuration information;
其中,所述第一配置信息用于配置第一秩最大值和第二秩最大值,所述第一秩最大值为所述第一指示域支持的最大秩的值,所述第二秩最大值为所述第二指示域支持的最大秩的值;或者,Wherein, the first configuration information is used to configure a first rank maximum value and a second rank maximum value, the first rank maximum value is the value of the maximum rank supported by the first indication domain, and the second rank maximum value The value is the value of the maximum rank supported by the second indication domain; or,
所述第一配置信息用于配置第三秩最大值,所述第三秩最大值为所述第
一指示域支持的最大秩的值。The first configuration information is used to configure a third rank maximum value, and the third rank maximum value is the A value indicating the maximum rank supported by the domain.
在实施中,上述第一配置信息可以是高层信令为所述目标PUSCH传输配置最大秩数的配置信息。In an implementation, the above-mentioned first configuration information may be configuration information in which higher layer signaling configures a maximum rank number for the target PUSCH transmission.
在一种可选地实施方式中,上述第一秩最大值为所述第一指示域支持的最大秩的值,可以理解为:假设第一秩最大值等于4,则第一指示域可以用于指示:1,2,3,4中的任一秩。同理,所述第二指示域指示的秩的值可以小于或者等于上述第二秩最大值。这样,通过两个秩最大值,分别指示第一指示域和第二指示域允许指示的最大秩数。In an optional implementation, the above-mentioned first rank maximum value is the value of the maximum rank supported by the first indication domain, which can be understood as: assuming that the first rank maximum value is equal to 4, the first indication domain can be Indicates: any rank among 1,2,3,4. Similarly, the value of the rank indicated by the second indication field may be less than or equal to the above-mentioned second maximum value of rank. In this way, the two rank maximum values respectively indicate the maximum number of ranks allowed for indication in the first indication domain and the second indication domain.
在另一种可选地实施方式中,上述第一配置信息仅用于配置第一指示域支持的最大秩的值,而第二指示域支持的最大秩的值则可以采用预设规则来根据第一指示域支持的最大秩的值确定。In another optional implementation, the above-mentioned first configuration information is only used to configure the value of the maximum rank supported by the first indication domain, while the value of the maximum rank supported by the second indication domain can be determined according to preset rules. The value of the maximum rank supported by the first indication domain is determined.
例如:在所述第一配置信息用于配置所述第三秩最大值的情况下,所述第二指示域支持的最大秩的值R′可以包括以下任一项:For example: in the case where the first configuration information is used to configure the third maximum rank value, the value R′ of the maximum rank supported by the second indication domain may include any of the following:
其中,Rmax表示所述第三秩最大值,表示对A向下取整; Among them, R max represents the third rank maximum value, Indicates rounding down A;
其中,表示对A向上取整; in, Indicates rounding up A;
R′=Rmax。R′=R max .
这样,相较于分别指示第一指示域和第二指示域允许指示的最大秩数的实施方式而言,仅指示第一指示域的第三最大秩数,且根据该第三最大秩数,采用预设规则来计算得到第二指示域支持的最大秩数的实施方式,能够减少第一配置信息的信息量。在实施中,具体采用哪一种预设规则来确定第二指示域支持的最大秩数,可以在协议中约定或者预先配置,在此不作具体限定。In this way, compared with the embodiment in which the maximum rank number of allowed indications of the first indication domain and the second indication domain is respectively indicated, only the third maximum rank number of the first indication domain is indicated, and according to the third maximum rank number, The implementation of using preset rules to calculate the maximum rank number supported by the second indication domain can reduce the amount of information in the first configuration information. In implementation, which preset rule is specifically used to determine the maximum number of ranks supported by the second indication domain can be agreed in the protocol or pre-configured, and is not specifically limited here.
本实施方式中,在第一DCI信令中携带两个TPMI域或者SRI域时,支持关联不同SRI的rank分别指示或者共用。In this embodiment, when the first DCI signaling carries two TPMI domains or SRI domains, the ranks associated with different SRIs are supported to be separately indicated or shared.
作为一种可选地实施方式,所述第一DCI信令还包括第二指示信息,所述第二指示信息用于指示以下规则中的至少一项生效:As an optional implementation manner, the first DCI signaling also includes second indication information, and the second indication information is used to indicate that at least one of the following rules is effective:
所述第一指示域与所述N个SRS资源集合中的第一个SRS资源集合关联,且所述第二指示域与所述N个SRS资源集合中的第二个SRS资源集合关联;
The first indication field is associated with a first SRS resource set among the N SRS resource sets, and the second indication field is associated with a second SRS resource set among the N SRS resource sets;
所述第一指示域与所述N个SRS资源集合中的第二个SRS资源集合关联,且所述第二指示域与所述N个SRS资源集合中的第一个SRS资源集合关联。The first indication field is associated with a second SRS resource set among the N SRS resource sets, and the second indication field is associated with a first SRS resource set among the N SRS resource sets.
在实施中,第二指示信息可以指示第一指示域和第二指示域分别与第一个SRS资源集合和第一个SRS资源集合之间的关联关系进行动态切换,在实施中,上述第二指示信息可以复用相关技术中用于指示beam切换的指示信息。例如:在相关技术中,假设第二指示信息为10时,指示第一个SRS资源集合与beam1对应,且第二个SRS资源集合与beam2对应;假设第二指示信息为11时,指示第二个SRS资源集合与beam1对应,且第一个SRS资源集合与beam2对应。在本申请实施例中,目标PUSCH在N个天线面板上同时发送时,第二指示信息为10和第二指示信息为11时的波束方案相同,本实施方式中,可以复用该第二指示信息来指示以上两种规则的切换。In an implementation, the second indication information may indicate dynamic switching of the association between the first indication domain and the second indication domain and the first SRS resource set and the first SRS resource set respectively. In the implementation, the above-mentioned second indication domain The indication information may reuse the indication information used to instruct beam switching in related technologies. For example: in the related technology, assuming that the second indication information is 10, it indicates that the first SRS resource set corresponds to beam1, and the second SRS resource set corresponds to beam2; assuming that the second indication information is 11, it indicates that the second The first SRS resource set corresponds to beam1, and the first SRS resource set corresponds to beam2. In the embodiment of this application, when the target PUSCH is transmitted simultaneously on N antenna panels, the beam scheme when the second indication information is 10 and the second indication information is 11 are the same. In this embodiment, the second indication can be multiplexed information to indicate the switching of the above two rules.
作为一种可选地实施方式,在N等于2,且所述目标传输方案为FDM传输方案的情况下,第一物理资源块(Physical Resource Block,PRB)数与第二PRB数之和等于第一DCI信令中的频域资源分配FDRA域所指示的所述目标PUSCH占用的PRB数;As an optional implementation manner, when N is equal to 2 and the target transmission scheme is an FDM transmission scheme, the sum of the first physical resource block (Physical Resource Block, PRB) number and the second PRB number is equal to the th The number of PRBs occupied by the target PUSCH indicated by the frequency domain resource allocation FDRA field in DCI signaling;
其中,所述第一PRB数为所述N个SRS资源集合中的第一个SRS资源集合关联的PUSCH传输资源所占用的第一PRB的数量;Wherein, the first number of PRBs is the number of first PRBs occupied by PUSCH transmission resources associated with the first SRS resource set among the N SRS resource sets;
所述第二PRB数为所述N个SRS资源集合中的第二个SRS资源集合关联的PUSCH传输资源所占用的第二PRB的数量;The second number of PRBs is the number of second PRBs occupied by the PUSCH transmission resources associated with the second SRS resource set among the N SRS resource sets;
所述第一DCI信令用于调度所述目标PUSCH。The first DCI signaling is used to schedule the target PUSCH.
本实施方式中,在目标PUSCH关联2个SRS资源集合的情况下,这两个SRS资源集合分别占用各自的PRB,且两个SRS资源集合所占用的PRB数之和等于FDRA域所指示的所述目标PUSCH占用的PRB数。In this embodiment, when the target PUSCH is associated with two SRS resource sets, the two SRS resource sets occupy their own PRBs, and the sum of the number of PRBs occupied by the two SRS resource sets is equal to the number indicated by the FDRA domain. The number of PRBs occupied by the target PUSCH.
在实施中,若FDRA域所指示的所述目标PUSCH占用的PRB数NPRB不能被N整除,则可以采用以下方式确定第一PRB数和第二PRB数:In implementation, if the number N PRBs occupied by the target PUSCH indicated by the FDRA domain is not divisible by N, the first and second PRB numbers may be determined in the following manner:
方式一:所述第一PRB数等于所述第二PRB数等于
Method 1: The first PRB number is equal to The second PRB number is equal to
方式二:所述第一PRB数等于所述第二PRB数等于
Method 2: The first PRB number is equal to The second PRB number is equal to
在实施中,可以默认按照方式一和方式二中的任一种来确定第一PRB数和第二PRB数。In implementation, the first PRB number and the second PRB number may be determined by default in either manner 1 or 2.
进一步地,上述第一PRB的起始频域位置可以是FDRA域指示的目标PUSCH占用的频域资源上从低频数的第一个PRB位置,当频域跳频功能开启时,可以以跳频之前的低频位置作为第一PRB的起始频域位置。换而言之,第一PRB为所述目标PUSCH占用的频域资源中包括最低频率位置在内的一段连续的频域位置。Further, the starting frequency domain position of the above-mentioned first PRB may be the first PRB position from the lower frequency on the frequency domain resource occupied by the target PUSCH indicated by the FDRA domain. When the frequency domain frequency hopping function is turned on, it may be in frequency hopping mode. The previous low-frequency position is used as the starting frequency domain position of the first PRB. In other words, the first PRB is a continuous frequency domain position including the lowest frequency position in the frequency domain resource occupied by the target PUSCH.

在SFN传输方案中,N个SRS资源集合关联的PUSCH资源上分别传输的相同的数据,但是,N个SRS资源集合关联的PUSCH资源分别可以使用不同的DMRS导频(对应不同DMRS端口),本实施方式中,通过为目标
PUSCH配置两个不同的PTRS端口,且每一个PTRS端口对应不同的CDM组内的DMRS端口,便可以使N个SRS资源集合关联的PUSCH资源分别可以使用不同的DMRS导频。In the SFN transmission scheme, the same data is transmitted on the PUSCH resources associated with the N SRS resource sets. However, the PUSCH resources associated with the N SRS resource sets can use different DMRS pilots (corresponding to different DMRS ports). This In the implementation, the goal is to pass PUSCH is configured with two different PTRS ports, and each PTRS port corresponds to a DMRS port in a different CDM group, so that the PUSCH resources associated with N SRS resource sets can use different DMRS pilots.
作为一种可选地实施方式,在所述目标传输方案为SFN传输方案的情况下,若所述目标PUSCH的波形为CP-OFDM波形,则第一偏移值为高层信令指示的资源元素偏移量resourceElementOffset对应的值,或者,所述第一偏移值为默认的第一资源元素偏移量对应的值;As an optional implementation manner, when the target transmission scheme is an SFN transmission scheme, if the waveform of the target PUSCH is a CP-OFDM waveform, the first offset value is the resource element indicated by the higher layer signaling. The value corresponding to the offset resourceElementOffset, or the first offset value is the value corresponding to the default offset of the first resource element;
其中,所述第一偏移值为与所述N个SRS资源集合中的第一个SRS资源集合关联的PUSCH传输资源上的PTRS在频域上的偏移值。Wherein, the first offset value is an offset value in the frequency domain of the PTRS on the PUSCH transmission resource associated with the first SRS resource set among the N SRS resource sets.
在具体实施中,resourceElementOffset的值可以是Offse00、Offse01、Offse10和Offse11中的任一项。在高层信令指示了resourceElementOffset对应的值的情况下,以该高层信令的指示为准,在高层信令未指示resourceElementOffset对应的值的情况下,则取默认的第一资源元素偏移量,例如:第一资源元素偏移量默认等于Offse00。In a specific implementation, the value of resourceElementOffset can be any one of Offse00, Offse01, Offse10 and Offse11. If the high-level signaling indicates the value corresponding to resourceElementOffset, the indication of the high-level signaling shall prevail. If the high-level signaling does not indicate the value corresponding to resourceElementOffset, the default offset of the first resource element shall be used. For example: the offset of the first resource element is equal to Offse00 by default.
通过本实施方式,可以确定所述N个SRS资源集合中的第一个SRS资源集合关联的PUSCH传输资源上的PTRS在频域上的偏移值。Through this embodiment, the offset value in the frequency domain of the PTRS on the PUSCH transmission resource associated with the first SRS resource set among the N SRS resource sets can be determined.
可选地,在所述目标传输方案为SFN传输方案的情况下,若所述目标PUSCH的波形为CP-OFDM波形,则第二偏移值为与所述第一偏移值相关的偏移值,或者,所述第二偏移值为默认的第二资源元素偏移量对应的值;Optionally, when the target transmission scheme is an SFN transmission scheme, if the waveform of the target PUSCH is a CP-OFDM waveform, the second offset value is an offset related to the first offset value. value, or the second offset value is the value corresponding to the default second resource element offset;
其中,所述第二偏移值为与所述N个SRS资源集合中的第二个SRS资源集合关联的PUSCH传输资源上的PTRS在频域上的偏移值。Wherein, the second offset value is an offset value in the frequency domain of the PTRS on the PUSCH transmission resource associated with the second SRS resource set among the N SRS resource sets.
在实施中,上述与所述第一偏移值相关的偏移值可以是:采用预设的计算规则来根据第一偏移值计算得到第二偏移值,例如:假设第一偏移值为V1,第二偏移值为V2,则可以根据公式V2=(V1+h)mod 12计算得到所述第二偏移值,其中,h为整数,这样可以降低所述N个SRS资源集合的PUSCH传输资源上的PTRS的相互干扰。In implementation, the above-mentioned offset value related to the first offset value may be: using a preset calculation rule to calculate the second offset value based on the first offset value, for example: assuming the first offset value is V1, and the second offset value is V2, the second offset value can be calculated according to the formula V2=(V1+h)mod 12, where h is an integer, which can reduce the set of N SRS resources. Mutual interference of PTRS on PUSCH transmission resources.
当然,在实施中,还可以直接默认第二偏移值等于第二资源元素偏移量对应的值,例如:第二资源元素偏移量默认等于Offse01。Of course, in implementation, the second offset value can also be directly defaulted to be equal to the value corresponding to the offset of the second resource element. For example, the offset of the second resource element is equal to Offse01 by default.
例如:在高层信令指示了resourceElementOffset对应的值的情况下,可以
基于该resourceElementOffset对应的值确定第一偏移值V1,并基于公式V2=(V1+h)mod 12计算得到所述第二偏移值;在高层信令未指示resourceElementOffset对应的值的情况下,可以默认第一偏移值等于Offse00对应的值,且默认第二偏移值等于Offse01对应的值。For example: when high-level signaling indicates the value corresponding to resourceElementOffset, you can The first offset value V1 is determined based on the value corresponding to the resourceElementOffset, and the second offset value is calculated based on the formula V2=(V1+h)mod 12; in the case where the high-level signaling does not indicate the value corresponding to the resourceElementOffset, The default first offset value may be equal to the value corresponding to Offse00, and the default second offset value may be equal to the value corresponding to Offse01.
PUSCH传输时,终端可以根据上述第一偏移值和第二偏移值,对关联两个SRS资源的PTRS做速率匹配。During PUSCH transmission, the terminal can perform rate matching on the PTRS associated with the two SRS resources based on the first offset value and the second offset value.
