为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
一、下行非相干传输
在NR系统中引入了基于多个TRP的下行和上行的非相干传输。其中，TRP之间的backhaul(回传网络)连接可以是理想的或者非理想的。理想的backhaul下TRP之间可以快速动态的进行信息交互。非理想的backhaul下由于时延较大TRP之间只能准静态的进行信息交互。在下行非相干传输中，多个TRP可以采用不同的控制信道独立调度一个终端的多个PDSCH(Physical Downlink Shared Channel，物理下行共享信道)传输，也可以采用同一个控制信道调度不同TRP的传输。其中不同TRP的数据采用不同的传输层，后者只能用于理想backhaul的情况。
对于采用多个PDCCH(Physical Downlink Control Channel，物理下行控制信道)调度的下行传输，所调度的PDSCH可以在相同的时隙或不同的时隙传输。终端需要支持同时接收来自不同TRP的PDCCH和PDSCH。终端反馈ACK/NACK(确认/非确认)和CSI时，可以将ACK/NACK和CSI各自反馈给传输相应PDSCH的不同TRP(如图2)，也可以合并反馈给一个TRP(如图3)。前者可以应用于理想backhaul和非理想backhaul两种场景，后者只能用于理想backhaul的场景。其中，不同TRP传输的用于调度PDSCH的DCI(Downlink control information，下行控制信息)可以通过不同的CORESET来承载，即网络侧配置多个CORESET。每个TRP采用各自的CORESET进行调度，即可以通过CORESET来区分不同的TRP。例如，网络设备可以为每个CORESET配置一个CORESET组索引，不同的索引对应不同的TRP。终端反馈CSI时，需要分别反馈每个TRP各自对应的CSI。该CSI包括RI(Rank Indication，秩指示)、PMI(Precoding Matrix Indicator，预编码矩阵指示)、CQI(Channel Quality Indication，信道质量指示)等内容，可以用于各自TRP进行下行传输的调度。
参见图4，对于采用单个PDCCH调度的多TRP下行传输，同一个DCI可以调度来自不同TRP的多个传输层。其中，来自不同TRP的传输层采用不同CDM(Code Division Multiplexing，码分复用)组中的DMRS(Demodulation Reference Signal，解调参考信号)端口，且采用不同的TCI(Transmission Configuration Indicator，传输配置指示)状态。网络设备需要在一个DCI中指示来自不同CDM组的DMRS端口，以及不同CDM组所分别对应的TCI状态，从而支持不同的DMRS端口采用不同的波束来传输。这种情况下，HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)-ACK反馈可以重用相关协议中的机制。这种方案只能用于理想backhaul的场景。而且，此时终端要在一个CSI中反馈不同TRP分别对应的RI和PMI，以及一个联合的CQI(用于确定MCS(Modulation and Coding Scheme，调制与编码策略))。
二、下行CSI上报
为了网络设备能够进行合理的调度，终端需要反馈下行CSI，以让基站确定传输层数、预编码矩阵、发送波束、调制编码方式等终端的调度信息。具体的，终端基于网络设备指示的CSI上报配置进行CSI上报。 终端反馈CSI反馈CSI所用的上行资源以及进行CSI测量所用的下行参考信号都可以通过CSI上报配置指示。每个CSI上报配置对应一个CSI上报，每个CSI上报可以包括CRI(Channel State Information Reference Signal Resource Indicator，信道状态信息参考信号资源指示)、RI、PMI、CQI等不同的信息。具体的，CSI中包括哪些内容/信息通过CSI上报配置中的上报量信息(reportQuantity)来确定。例如：上报量信息可以指示以下上报量中的一个：
Figure PCTCN2021085141-appb-000001
其中：
CRI用于从多个CSI-RS(Channel State Information Reference Signal，信道状态信息参考信号)资源中确定当前用于信道测量的CSI-RS资源，以及当前用于干扰测量的干扰测量资源IMR(Interference Measurement Resource，干扰测量资源)。
RI用于反馈推荐的传输层数(Rank)。
PMI用于从预定义的码本中确定推荐的预编码矩阵。
CQI用于反馈当前的信道质量，可以基于终端估计的SINR(Signal to Interference plus Noise Ratio，下行信号与干扰加噪声比)确定。其中，SINR中的信道部分基于网络配置的用于信道测量的非零功率CSI-RS确定，干扰部分基于网络配置的用于干扰测量的CSI-IM(Channel State Information Interference Measurement，信道状态信息干扰测量)或者非零功率CSI-RS确定。CQI基于反馈的RI和PMI计算。
RSRP(ReferenceSignal Receiving Power，参考信号接收功率)用于上报所反馈的索引对应的SSB(Synchronization Signal and PBCH block，同步信号和PBCH(Physical Broadcast Channel，广播物理信道)块)或CSI-RS的RSRP，从而用于网络侧确定下行传输所用的波束。
LI(layer index，层索引)用于指示与PTRS(Phase Tracking Reference Signal，相位跟踪参考信号)关联的传输层的索引。
当一个CSI中承载的比特数较多时，为了优先传输重要的CSI信息，可以将一个CSI分成两个部分(part)。对于不同类型的码本，CSI部分1和部分2包括的信息如下表所示。其中，CSI部分1的比特数是固定的，用来携带RI、CQI等少量重要信息；CSI部分2的比特数根据CSI部分1确定，用来携带PMI等比特数较多的信息。当携带CSI的PUSCH(物理上行共享信道)/(物理上行控制信道)PUCCH的码率超过一定值时， 终端需要丢弃一些CSI部分2中的信息来保证PUSCH/PUCCH的传输性能，至少码率在合理范围内。具体的，CSI部分1的信息不会被丢弃，CSI部分2中根据CSI上报的优先级先丢弃优先级较低的CSI。其中，CSI上报的优先级根据CSI的周期性、CSI上报的内容、CSI上报对应的载波和CSI上报配置的ID判断。
Figure PCTCN2021085141-appb-000002
在相关技术中，为了测量协作的多个TRP的CSI，网络设备可以给终端配置两个CMR(Channel Measurement Resource，信道测量资源)组，每组用于测量一个TRP的CSI。终端基于配置的两个CMR组进行测量，从而确定当前最优的CSI是基于单个TRP(即单个CMR组或者单个CMR)测量得到，还是基于多个TRP(即两个CMR组或者两个CMR)测量得到。其中，前者对应于单个TRP的测量假设，后者对应NC-JT(Non-Coherent Joint Transmission，非相干联合传输)的测量假设。终端可以在CSI中反馈当前推荐的测量假设是其中哪一个，以及该测量假设下对应的CSI，例如CRI、RI、PMI、CQI等。目前，需要考虑如何用最小的信令开销反馈推荐的测量假设，以及如何确定该测量假设下的CRI和RI信息。

本申请实施例中，终端设备可以基于多个CMR组反馈推荐的测量假设，以及相应测量假设下的一个或者两个RI，从而网络侧可以获得当前CMR配置下最佳的传输方案以及相应的RI，提高下行传输的吞吐量。
在具体的应用示例中，本申请的信息处理方法可以为一种CSI上报方法。终端基于两个CMR组进行CSI测量，从而通过CSI上报中的第一信息反馈该CSI的测量假设，并通过该CSI上报中的RI信息反馈该测量假设下的RI。具体的，本申请实施例可以提供多种不同的测量假设和RI信息的上报方法。根据本申请实施例的方法，终端可以基于多个CMR组反馈推荐的测量假设，以及相应测量假设下的一个或者两个RI。从而网络侧可以获得当前CMR配置下最佳的传输方案以及相应的RI，提高下行传输的吞吐量。以下为几个具体的示例。
示例1:
S11.终端接收网络设备配置的用于信道测量的非零功率CSI-RS资源(即CMR)集合，该集合中包括两个CMR组。
具体的，该集合包括K个非零功率CSI-RS资源，可以分成两个大小为K/2的CMR组。另一种实施方式中，该两个CMR组包括的CMR的数量也可以不同，每个组包括的CMR由网络设备通过高层信令配置给终端。
另外，网络设备还可以通过高层信令配置N个用于NC-JT测量的CMR组合，每个组合包括分别来自该两个CMR组的两个CMR。例如，一个CMR组合包括CMR1和CMR2，其中CMR1来自于一个CMR组，CMR2来自于另一个CMR组。
S12.终端基于该两个CMR组进行CSI测量。
具体的，终端可以基于该两个CMR组包括的K个CMR资源分别进行单TRP的CSI测量，即每个CSI测量只基于单个CMR。终端还可以基于该N个用于NC-JT测量的CMR组合分别进行多TRP的CSI测量，即每个CSI测量都是基于一个CMR组合(两个CMR)进行。
终端可以根据基于单个CMR测量得到的最好的CSI，和基于CMR组合(两个CMR)测量得到的最好的CSI中，确定其中较优的CSI测量假设，并将该测量假设和相应的CSI通过CSI上报反馈给网络设备。
S13.终端通过CSI上报中的第一信息反馈CSI的测量假设。
具体的，该测量假设为该CSI测量所基于的CMR，或者为该CSI测量所基于的CMR的数量。在本申请实施例中，该测量假设为该CSI测量基于单个CMR，也可以称为该CSI测量基于单TRP传输的测量假设。该测量假设为该CSI测量基于多个CMR，也可以称为该CSI测量基于NC-JT传输的测量假设。
在一种实施方式中，该第一信息为该CSI上报中的CRI信息。该CRI信息指示该两个CMR组中的一个或者两个CMR。此时，该CRI信息指示的CMR即为该CSI的测量假设，即CSI测量所基于的CMR。
例如，该CRI信息的比特数为log 2(K+N)，其中，K为该两个CMR组包括的CMR的总数(即该用于信道测量的非零功率CSI-RS资源集合中的数量)，N为该两个CMR组中用于NC-JT测量的CMR组合的数量，该用于NC-JT测量的CMR组合可以通过高层信令由网络设备配置给终端。这样，通过CRI信息可以指示K个CMR中的一个CMR(对应基于单个CMR的测量假设)，或者N个CMR组合中的一个CMR组合(对应基于两个CMR的测量假设)。
在另一种实施方式中，该第一信息为该CSI上报中的测量假设信息。该测量假设信息的不同取值分别对应基于单个CMR的测量假设和基于两个CMR的测量假设，或者，基于单个TRP的测量假设和基于NC-JT的测量假设。
例如，该测量假设信息包括1比特信息，其中0表示基于单个CMR的测量假设或者基于单个TRP的测量假设，1表示基于两个CMR的测量假设或者基于NC-JT的测量假设。
再如，此时该CSI中包括的CRI信息的比特数为log 2(max(K,N))，其中，K为该两个CMR组包括的CMR的总数，N为该两个CMR组中用于NC-JT测量的CMR组合的数量。这样，当该测量假设信息指示基于单个CMR的测量假设时，通过CRI信息可以指示K个CMR中的一个CMR；当该测量假设信息指示基于两个CMR的测量假设时，通过CRI信息可以指示N个CMR组合中的一个CMR组合。
S14.终端通过该CSI上报中的RI信息反馈该测量假设下的Rank。
具体的，该RI信息包括两个RI(即两个独立的RI指示域)，且该两个RI中的第一RI(指示域)的比特数大于第二RI(指示域)的比特数。
在一种实施方式中，该第一RI包括3个比特，用于指示Rank＝{1,2,...,8}中的一个；该第二RI包括2个比特，用于指示Rank＝{1,2,...,4}中的一个。在另一种实施方式中，该第一RI包括2个比特，用于指示Rank＝{1,2,3,4}中的一个；该第二RI包括1个比特，用于指示Rank＝{1,2}中的一个。
在一种实施方式中，当该测量假设为该CSI测量基于单个CMR时，该第一RI基于该单个CMR测量得到，该第二RI不指示Rank。其中，该单个CMR为该CSI上报中的CRI信息所指示的CMR。此时，该第一RI是一个有效的RI，可以用于单个TRP的下行传输；该第二RI的比特数不用于指示Rank，可以预留或者用于其他用途。
在另一种实施方式中，当该测量假设为该CSI测量基于两个CMR时，该第一RI和第二RI分别基于该两个CMR测量得到。其中，该两个CMR为该CSI上报中的CRI信息所指示的一个CMR组合。此时，该两个RI均为有效的RI，分别用于不同TRP的下行传输。
在这种情况下，该第一RI指示的Rank不大于该第二RI可以指示的最大Rank。例如，第一RI为3比特，第二RI为2比特且指示的Rank值为{1,2,3,4}，则第一RI指示的Rank值也不能超过4，只能为1-4中的一个，不能指示Rank＝5-8。
采用该示例的方法，可以保证Rank指示的灵活性，在不同的测量假设下都可以反馈各种Rank取值的灵活组合。
示例2:
S21.终端接收网络设备配置的用于信道测量的非零功率CSI-RS资源(即CMR)集合，该集合中包括两个CMR组。
具体的，该集合包括K个非零功率CSI-RS资源，可以分成两个大小为K/2的CMR组。另一种实施方式中，该两个CMR组包括的CMR的数量也可以不同，每个组包括的CMR由网络设备通过高层信令配置给终端。
另外，网络设备还可以通过高层信令配置N个用于NC-JT测量的CMR组合，每个组合包括分别来自该两个CMR组的两个CMR。例如，一个CMR组合包括CMR1和CMR2，其中CMR1来自于一个CMR组，CMR2来自于另一个CMR组。
S22.终端基于该两个CMR组进行CSI测量。
具体可以参考示例1中的内容，这里不再赘述。

在一种实施方式中，该第一信息为该CSI上报中的CRI信息。该CRI信息指示该两个CMR组中的一个或者两个CMR。此时，该CRI信息指示的CMR即为该CSI的测量假设，即CSI测量所基于的CMR。具体可以参考示例1中的描述。
在另一种实施方式中，该第一信息为该CSI上报中的测量假设信息。该测量假设信息的不同取值分别对应基于单个CMR的测量假设和基于两个CMR的测量假设，或者，基于单个TRP的测量假设和基于NC-JT的测量假设。具体可以参考示例1中的描述。
S24.终端通过该CSI上报中的RI信息反馈该测量假设下的Rank。
具体的，该RI信息包括一个RI，该RI用于指示一个或者两个Rank，且RI的不同取值指示的Rank的数量是相同的(一个或两个)。
当该测量假设为该CSI测量基于单个CMR(即基于单个TRP的测量假设)时，该RI用于指示一个Rank，该Rank基于该单个CMR测量得到，该单个CMR通过该CSI上报中的CRI信息指示。
具体的，该RI指示的Rank为{1,2,…,8}中的一个。
当该测量假设为该CSI测量基于两个CMR时，该RI用于指示两个Rank的组合，该两个Rank分别基于该两个CMR测量得到，该两个CMR通过该CSI上报中的CRI信息指示。
在一种实施方式中，该RI为4个比特，指示的Rank值如下：

2 2 {1,2}
3 3 {2,1}
4 4 {2,2}
5 5 Reserved(保留位)
6 6 Reserved
7 7 Reserved
8 8 Reserved
在一种实施方式中，当该测量假设通过单独的测量假设信息指示时，该CSI上报中包括的CRI信息的比特数为log 2(max(K,N))。当该测量假设信息指示基于单个CMR的测量假设时，通过CRI信息可以指示K个CMR中的一个CMR；当该测量假设信息指示基于两个CMR的测量假设时，通过CRI信息可以指示N个CMR组合中的一个CMR组合。
在另一种实施方式中，当该测量假设通过CRI信息指示时，该CSI上报中的CRI信息的比特数为log 2(K+N)。通过CRI信息可以指示K个CMR中的一个CMR，或者N个CMR组合中的一个CMR组合。
采用该示例的方法，不同测量假设下的Rank值重用相同的RI信息域来指示，可以减少CSI上报中的信息比特数，从而提高UCI(Uplink control information，上行控制信息)传输的性能。

另外，网络设备还可以通过高层信令配置N个用于NC-JT测量的CMR组合，每个组合包括分别来自该两个CMR组的两个CMR。例如，一个CMR组合包括CMR1和CMR2，其中CMR1来自于一个CMR组，CMR2来自于另一个CMR组。

具体参考示例1中的内容，这里不再赘述。
S33.终端通过CSI上报中的第一信息反馈CSI的测量假设。
具体的，该测量假设为该CSI测量所基于的CMR，或者为该CSI测量所基于的CMR的数量。
在一种实施方式中，该第一信息为RI信息，该RI信息指示的不同Rank对应不同的测量假设。
例如，该RI信息指示两个Rank，当该RI信息指示的其中一个Rank取值为零时，该CSI基于单个CMR的测量假设；当该RI信息指示的两个Rank均大于零时，该CSI基于两个CMR的测量假设。
例如，此时该CSI上报中包括的CRI信息的比特数为log 2(K/2)或者log 2(max(K/2,N))。
S34.终端通过该CSI上报中的RI信息反馈该测量假设下的Rank。
具体的，该RI信息包括一个RI，该RI用于指示第一Rank和第二Rank的组合。其中，第一Rank和第二Rank中至少有一个取值不为零。
具体的，该RI的部分取值范围指示的一个Rank大于0，另一个Rank等于0，对应基于单个CMR的测量假设；另一部分取值范围指示的两个Rank均大于零，对应基于两个CMR的测量假设。

在一种实施方式中，当第一Rank大于0，第二Rank等于0时，该CSI基于第一CMR测量得到，该第一CMR为该两个CMR组中的第一CMR组中，CRI信息所对应的CMR。当第二Rank大于0，第一Rank等于0时，该CSI基于第二CMR测量得到，该第二CMR为该两个CMR组中的第二CMR组中，CRI信息所对应的CMR。此时，该CRI信息的有效比特数为log 2(K/2)，用于指示非零Rank对应的一个CMR组中的一个CMR。
在另一种实施方式中，当第一Rank和第二Rank都大于0时，该第一Rank和第二Rank分别基于第一CMR和第二CMR测量得到，该第一CMR和第二CMR分别为该两个CMR组中，CRI信息所对应的CMR。此时，该CRI信息的有效比特数为log 2(K/2)，用于指示两个CMR组中CRI信息分别对应的两个CMR；或者，该CRI信息的有效比特数为log 2(max(K/2,N))，用于指示N个用于NC-JT测量的CMR组合中的一个组合。
采用该示例的方法，通过RI指示的Rank组合来反馈所用的测量假设，可以降低CSI上报中CRI信息的比特数，同时不需要额外的测量假设信息，从而降低CSI的整体负载(payload)，提高UCI的传输性能。

在以上表格中，考虑小区边缘UE只能支持较低的Rank，因此可以通过限制Rank的取值范围，来进一步降低RI指示域的信令开销。
当该RI指示一个Rank时，该Rank基于第三CMR测量得到，该第三CMR为该两个CMR组(即该CMR资源集合)的K个CMR中CRI信息所对应的CMR。此时，该CRI信息的有效比特数为log 2(K)，用于指示该K个CMR中的一个CMR。

采用该示例的方法，通过RI指示的Rank数量来反馈所用的测量假设，可以降低CSI上报中CRI信息的比特数，同时不需要额外的测量假设信息，从而降低CSI的整体payload，提高UCI的传输性能。
