在现有技术中，终端设备针对每个信道状态信息(Channel State Information，CSI)上报配置反馈一个CSI，所述CSI基于网络配置的信道测量资源和干扰测量资源计算得到，只能用于获得一个传输点/发送接收点(Transmission/reception point，TRP)在一个传输方案假设下的信道信息。为了同时支持单TRP传输和多TRP的下行非相干联合传输(Non-Coherent Joint transmission，NC-JT)，网络设备需要指示终端设备上报基于不同传输方案假设下的多个CSI。典型的，网络设备需要配置多个CSI上报配置，有些配置对应单TRP传输，有些配置对应多TRP的NC-JT，但这些配置对应的测量资源是相同的。这种上报方式需要多套CSI上报配置，也需要大量的CSI上报开销，从而浪费了下行信令，也影响上行信道的传输性能；而且会引入较大的CSI反馈时延，从而影响下行传输的性能。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
下面对本申请实施例涉及的术语进行简要说明，如下所示：
1、下行非相干传输
在新无线(New Radio，NR)系统中引入了基于多个传输点/发送接收点(Transmission/reception point，TRP)的下行和上行的非相干传输。其中，TRP之间的回程线路(backhaul)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物理下行共享信道(Physical Downlink Shared Channel，PDSCH)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。
对于采用多个物理下行控制信道(Physical Downlink Control Channel，PDCCH)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。终端反馈确认(ACK，Acknowledge)/非确认(NACK)和信道状态信息(Channel State Information，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1A所示，为基于多PDCCH的下行非相干传输的一个示意图)，也可以合并上报给一个TRP(如图1B所示，为基于多PDCCH的下行非相干传输的一个示意图)。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的下行控制信息(Downlink control information，DCI)可以通过不同的控制资源集(Control Resource Set，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。所述CSI包含秩指示(Rank Indicator，RI)，预编码矩阵指示(Precoding Matrix Indicator，PMI)，信道质量指示(Channel Quality Indicator，CQI)等内容，可以用于各自TRP进行下行传输的调度。
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的传输层采用不同码分多路复用(Code division multiplexing，CDM)组中的解调 参考信号(Demodulation Reference Signal，DMRS)端口，且采用不同的传输配置指示(Transmission Configuration Indication，TCI)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，混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)-ACK反馈和CSI上报可以重用现有协议中的机制。这种方案只能用于理想backhaul的场景。如图1C所示，为基于单PDCCH的下行非相干传输的一个示意图。
2、下行CSI上报
为了网络设备能够进行合理的调度，终端需要反馈下行信道状态信息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，终端的CSI上报基于网络设备指示的CSI上报配置进行，终端上报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是通过CSI上报配置指示。每个CSI上报配置对应一个CSI上报，每个CSI上报可以包含CSI-RS资源指示(CSI-RS Resource Indicator，CRI)，RI，PMI，CQI等不同的信息。具体的，CSI中包含哪些内容/信息通过CSI上报配置中的上报量信息(reportQuantity)来确定。所述上报量信息可以指示以下上报量中的一个(详见3GPP TS 38.331)：
Figure PCTCN2021080310-appb-000001
需要说明的是，以cri-RI-PMI-CQI为例进行说明，表示上报量信息中包括的上报量为：一个cri、一个RI、一个PMI和一个CQI，即“-”表示“和”的意思。其他的表达可以参考此说明，下文中不再一一赘述。“i1”表示一个宽带的PMI指示。
其中，CSI-RS资源指示(CSI-RS Resource Indicator，CRI)用于从多个CSI-RS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(Interference Measurement Resource，IMR)；
RI用于上报推荐的传输层数；
PMI用于从预定义的码本中确定推荐的预编码矩阵；
CQI用于上报当前的信道质量，可以基于终端估计的信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)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或者非零功率CSI-RS确定。CQI基于上报的RI和PMI计算。
参考信号接收功率(Reference Signal Received Power，RSRP)用于上报所反馈的索引对应的同步信号和物理广播信道(phisical broadcast Channel，PBCH)块(Synchronization Signal and PBCH block，SSB)或CSI-RS的RSRP，从而用于网络侧确定下行传输所用的波束。
传输层指示(Layer indicator，LI)用于上报与相位跟踪参考信号(Phase Tracking Reference Signal，PTRS)关联的传输层的索引。
终端的CSI上报可以有三种周期性上报方式：周期性CSI，准持续性CSI和非周期CSI。如图1D所示，为不同周期性的CSI上报方式的一个示意图。其中，周期性CSI在PUCCH上传输，其CSI上报配置由无线资源控制(Radio Resource Control，RRC)配置，终端接收到相应RRC配置后，周期性地上报CSI。准持续性CSI可以在PUCCH或PUSCH上传输，PUCCH上传输的CSI对应的CSI上报配置由RRC信令预配置，并由媒体接入控制(Media Access Control，MAC)层信令进行激活或去激活，PUSCH上传输的CSI对应的CSI上报配置通过DCI信令动态指示(激活或去激活)。终端接收到网络配置的激活或指示信令后，在PUCCH或PUSCH上周期性传输CSI，直到接收到去激活信令后停止上报。非周期性的 CSI上报对应的CSI上报配置也通过RRC信令预配置，可以通过MAC层信令激活其中的部分配置，再通过DCI中的CSI触发信令指示用于CSI上报的CSI上报配置。终端接收到CSI触发信令后，根据指示的CSI上报配置在所调度的PUSCH上一次性上报对应的CSI。
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包含的信息如下表1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/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。

表1
在现有技术中，终端针对每个CSI上报配置反馈一个CSI，所述CSI基于网络配置的信道测量资源和干扰测量资源计算得到，只能用于获得一个TRP在一个传输方案假设下的信道信息。为了同时支持单TRP传输和多TRP的下行非相干联合传输(Non-Coherent Joint transmission，NC-JT)，网络设备需要指示终端上报基于不同传输方案假设下的多个CSI。典型的，网络设备需要配置多个CSI上报配置，有些配置对应单TRP传输，有些配置对应多TRP的NC-JT，但这些配置对应的测量资源是相同的。这种上报方式需要多套CSI上报配置，也需要大量的CSI上报开销，从而浪费了下行信令，也影响上行信道的传输性能；而且会引入较大的CSI反馈时延，从而影响下行传输的性能。

其中，CRI-RI-PMI-CQI表示终端设备需要上报一个CRI(只在配置多个CSI-RS资源时上报)，一个RI，一个PMI和一个CQI，CRI-2RI-2PMI-CQI表示终端设备需要上报一个CRI，两个RI，两个PMI和一个CQI，也可以表示为CRI-RI-RI-PMI-PMI-CQI，CRI-nRI-nPMI-CQI表示终端设备需要上报一个CRI，一个或两个RI，一个或两个PMI和一个CQI，以此类推。
其中，所述第一上报量集合可以不包含CRI-2RI-CQI和CRI-nRI-CQI。
其中，对于9-14中的任意一个，上报量中可以不包含CRI。
例如，所述第一上报量信息(reportQuantity0)可以是如下高层信令：

或者，
Figure PCTCN2021080310-appb-000004
或者，
Figure PCTCN2021080310-appb-000005
Figure PCTCN2021080310-appb-000006
(2)可选的，所述第二上报量信息(reportQuantity1)指示第二上报量集合中的上报量，所述第二上报量集合包含：

7.2CRI-2RI-2LI-2PMI-2CQI。
其中，2-7的CSI基于单个CMR进行测量得到，对应单个TRP传输需要终端设备上报的CSI内容。2-4上报的CSI为最好的基于单个CMR的CSI测量结果(对应于两个TRP中最好的一个单TRP的测量假设)，其中CRI用于指示推荐的一个CMR(或者CMR/IMR组合，对应于推荐的TRP)，其他CSI基于推荐的CMR(或者CMR/IMR组合)测量得到；5-7对应的上报量包含两个CSI(分别为两个TRP各自的CSI)，每个CSI基于一组CMR测量得到，终端设备通过两个CRI分别上报两个CMR组内推荐的一个CMR(即两个TRP各自最好的CMR)，其他的CSI基于推荐的CMR(或者CMR/IMR组合)测量得到。
其中，2CRI-2RI-2PMI-2CQI表示终端设备需要上报两组CSI，每组CSI包含CRI-RI-PMI-CQI(对应一个TRP)，每组CSI分别基于一组CMR测量得到，网络设备预先通过高层信令配置对应的两组CMR，以此类推。
其中，所述第二上报量集合可以不包含CRI-RI-CQI和2CRI-2RI-2CQI。
其中，对于5-7中的任意一个，上报量中可以不包含CRI。
例如，所述第二上报量信息(reportQuantity1)可以是如下高层信令：
Figure PCTCN2021080310-appb-000007
或者，
Figure PCTCN2021080310-appb-000008
或者，
Figure PCTCN2021080310-appb-000009
Figure PCTCN2021080310-appb-000010
在一种实施方式中，当第一上报量信息指示CRI-nRI-nPMI-CQI，CRI-nRI-CQI或CRI-nRI-nLI-nPMI-CQI时，第二上报量信息只能指示“无内容”。
基于这两个上报量信息，终端设备可以在同一个CSI上报中反馈一个或多个单TRP的CSI和多TRP联合传输的CSI，从而网络设备可以根据上报的CSI进行单TRP传输和多TRP联合传输的动态切换，得到更高的下行吞吐量。其中，第一上报量信息可以用于上报基于传统的单TRP测量假设的CSI，或者上报基于多TRP的NC-JT测量假设的CSI，或者上报单TRP和NC-JT的测量假设中最好的一个测量假设对应的CSI；第二上报量信息可以用于上报基于最好的单TRP测量假设的CSI(即两个TRP中最好的一个TRP的CSI)，或者同时上报两个TRP各自对应的CSI。
402、终端设备根据所述两个上报量信息分别测量对应的CSI。
在一种实施方式中，当上报量中包含2组RI/PMI时，或者包含2组CRI/RI/PMI/CQI时(包含n＝2的情况)，两组RI/PMI或者CRI/RI/PMI/CQI分别基于不同的CMR组得到。当上报量中包含2组RI/PMI和1个CQI时，所述CQI基于两组CMR测量得到。
在一种实施方式中，所述两个上报量信息中至少两个上报量信息对应的CSI基于相同的CMR测量得到。具体的，一个CMR可以同时用于单个TRP的测量假设和NC-JT的测量假设。例如，当第一上报量信息指示CRI-2RI-2PMI-CQI或CRI-2RI-CQI或CRI-2RI-2LI-2PMI-CQI，第二上报量信息指示CRI-RI-PMI-CQI或CRI-RI-CQI或CRI-RI-LI-PMI-CQI时，他们对应的CSI测量使用的CMR集合可以是相同的两个集合。例如，当第一上报量信息指示CRI-2RI-2PMI-CQI或CRI-2RI-CQI或CRI-2RI-2LI-2PMI-CQI，第二上报量信息指示2CRI-2RI-2PMI-2CQI或2CRI-2RI-2CQI或2CRI-2RI-2LI-2PMI-2CQI时，第一上报量信息对应的CSI测量使用的两个CMR集合，分别用于第二上报量信息对应的两组CSI进行CSI测量。
在本实施例中，如果一个上报量信息指示无内容，则终端设备不需要测量该上报量信息对应的CSI。例如，网络设备可以配置所有的上报量信息均指示“无内容”，此时终端设备不需要进行CSI测量；或者，只配置第二上报量信息指示无内容，此时终端设备只需要测量第一上报量信息对应的CSI。通过这种方式，这种CSI反馈方式可以回退到当前协议的CSI反馈方式，从而具备后向兼容性。
403、终端设备在同一个CSI上报中反馈所述两个上报量信息中至少一个上报量信息对应的CSI。
可选的，如果终端设备要反馈所述两个上报量信息分别对应的CSI，则可以将所述两个上报量信息各自对应的CSI按照所述两个上报量信息的配置顺序进行级联后，在同一个CSI上报中反馈。级联的方法可以是配置顺序在前的上报量信息对应的CSI在前。例如，假设所述两个上报量信息分别为reportQuantity0和reportQuantity1(reportQuantity0的配置顺序在前)，对应的CSI分别为CSI0和CSI1，则终端设备将这两个CSI按照{CSI0，CSI1}的顺序进行级联后在同一个CSI中上报。
可选的，在所述CSI上报中的部分CSI需要丢弃时，按照所述两个上报量信息的配置顺序依次进行丢弃。例如，当承载所述CSI上报的PUSCH/PUCCH的码率超过一定门限时，需要丢弃其中部分的CSI，从而保证丢弃后的码率不会超过该门限。假设所述两个上报量信息分别为reportQuantity0和reportQuantity1(reportQuantity0的配置顺序在前)，对应的CSI分别为CSI0和CSI1，则在丢弃CSI时，可以先丢弃配置顺序在后的上报量信息对应的CSI(即CSI1)，在需要时再丢弃配置顺序在前的上报量信息对应的CSI(即CSI0)，直到码率满足门限。
在以上方法中，如果一个上报量信息指示无内容，则终端设备不需要上报该上报量信息对应的CSI。例如，网络设备可以配置所有的上报量信息均指示“无内容”，此时终端设备不需要上报任何CSI；或者，只配置第二上报量信息指示无内容，此时终端设备只需要上报第一上报量信息对应的CSI。
在本申请实施例中，可以通过在CSI上报配置中的多个上报量信息令终端设备在同一个CSI上报中反馈一个或多个单TRP的CSI和多TRP联合传输的CSI，且反馈哪几个传输假设的CSI可以灵活配置，从而网络设备可以根据上报的CSI进行单TRP传输和多TRP联合传输的动态切换，得到更高的下行吞吐量。同时，通过将一些上报量信息配置成无内容，可以保证很好的后向兼容性，回退到现有的CSI上报方式。

其中，对于9-11中的任意一个，上报量中可以不包含CRI。

(2)可选的，所述第二上报量信息(reportQuantity1)指示第二上报量集合中的上报量，所述第二上报量集合包含：

6、2CRI-2RI-2CQI；
7、2CRI-2RI-2LI-2PMI-2CQI；
8、CRI-2RI-2PMI-CQI；
9、CRI-2RI-CQI；
10、CRI-2RI-2LI-2PMI-CQI。
其中，2-4对应基于最好的一个单TRP测量假设的CSI上报，5-7对应两个基于单TRP测量假设的CSI上报，8-10对应基于NC-JT测量假设的CSI上报，每个上报量的含义参考上述实施例二的描述，此处不再赘述。
其中，所述第二上报量集合可以不包含CRI-RI-CQI，2CRI-2RI-2CQI和CRI-2RI-CQI。
其中，对于5-10中的任意一个，上报量中可以不包含CRI。

或者，
Figure PCTCN2021080310-appb-000016
或者，
Figure PCTCN2021080310-appb-000017
基于这两个上报量信息，终端设备可以在同一个CSI上报中反馈一个或多个单TRP的CSI和多TRP联合传输的CSI，从而网络设备可以根据上报的CSI进行单TRP传输和多TRP联合传输的动态切换，得到更高的下行吞吐量。其中，第一上报量信息可以用于上报基于传统的单TRP测量假设的CSI，或者上报基于多TRP的NC-JT测量假设的CSI；第二上报量信息可以用于上报基于最好的单TRP测量假设的CSI(即两个TRP中最好的一个TRP的CSI)，或者同时上报两个TRP各自对应的CSI，或者上报基于NC-JT测量假设的CSI。
502、终端设备根据所述两个上报量信息分别测量对应的CSI。
可参考图4所示实施例中步骤402中的说明，此处不再赘述。
503、终端设备在同一个CSI上报中反馈所述两个上报量信息中至少一个上报量信息对应的CSI。
具体的，终端设备接收网络设备预先配置的上报类型信息，该上报类型信息可以包含在所述CSI上报配置(CSI-ReportConfig)中。终端设备根据该上报类型信息确定采用上报类型1还是上报类型2进行CSI上报，并根据确定的上报类型进行CSI上报。其中，上报类型1为分别上报所述多个上报量信息各自对应的CSI，上报类型2为从所述多个上报量信息对应的CSI中选择最佳的一个上报量信息对应的CSI进行上报。
在一种实施方式中，当终端设备分别上报所述多个上报量信息各自对应的CSI时，可以将所述两个上报量信息各自对应的CSI按照所述两个上报量信息的配置顺序进行级联后，在同一个CSI上报中反馈。级联的方法可以是配置顺序在前的上报量信息对应的CSI在后。例如，假设所述两个上报量信息分别为reportQuantity0和reportQuantity1(reportQuantity0的配置顺序在前)，对应的CSI分别为CSI0和CSI1，则终端设备将这两个CSI按照{CSI1，CSI0}的顺序进行级联后在同一个CSI中上报。
在一种实施方式中，当终端设备从所述多个上报量信息对应的CSI中选择最佳的一个上报量信息对应的CSI进行上报时，未选择的CSI不进行上报。进一步的，终端设备同时上报所选择的上报量信息的指示信息，或者所选择的上报量信息对应的CSI的指示信息。例如，终端设备可以通过CSI中的1比特信息来指示当前上报的CSI是reportQuantity0对应的CSI，还是reportQuantity1对应的CSI。如果所述CSI包含CSI部分1和CSI部分2，该指示信息可以包含在CSI部分1中。
在以上方法中，如果一个上报量信息指示无内容，则终端设备不需要上报该上报量信息对应的CSI。例如，网络设备可以配置所有的上报量信息均指示“无内容”，此时终端设备不需要上报任何CSI；或者，只配置第二上报量信息指示无内容，此时终端设备只需要上报第一上报量信息对应的CSI。在后面这种情况下，上报类型信息将不起作用。
在本申请实施例中，可以通过在CSI上报配置中的多个上报量信息令终端设备在同一个CSI上报中反馈一个或多个单TRP的CSI和多TRP联合传输的CSI，且反馈哪几个传输假设的CSI可以灵活配置，从而网络设备可以根据上报的CSI进行单TRP传输和多TRP联合传输的动态切换，得到更高的下行吞吐量。同时，通过将一些上报量信息配置成无内容，可以保证很好的后向兼容性，回退到现有的CSI上报方式。

基于这两个上报量信息，终端设备可以在同一个CSI上报中反馈一个或多个单TRP的CSI和多TRP联合传输的CSI，从而网络设备可以根据上报的CSI进行单TRP传输和多TRP联合传输的动态切换，得到更高的下行吞吐量。其中，第一上报量信息可以用于上报基于传统的单TRP测量假设的CSI，或者上报基于多TRP的NC-JT测量假设的CSI，或者上报用于多TRP的波束管理的CSI；第二上报量信息可以用于上报基于最好的单TRP测量假设的CSI(即两个TRP中最好的一个TRP的CSI)，或者同时上报两个TRP各自对应的CSI。

b)在以上方法中，如果一个上报量信息指示无内容，则终端设备不需要上报该上报量信息对应的CSI。例如，网络设备可以配置所有的上报量信息均指示“无内容”，此时终端设备不需要上报任何CSI；或者，只配置第二上报量信息指示无内容，此时终端设备只需要上报第一上报量信息对应的CSI。在这种情况下，终端设备不需要在CSI中包含上报类型的信息。
在本申请实施例中，可以通过在CSI上报配置中的多个上报量信息令终端设备在同一个CSI上报中反馈一个或多个单TRP的CSI和多TRP联合传输的CSI，且反馈哪几个传输假设的CSI可以灵活配置，从而网络设备可以根据上报的CSI进行单TRP传输和多TRP联合传输的动态切换，得到更高的下行吞吐量。同时，通过将一些上报量信息配置成无内容，可以保证很好的后向兼容性，回退到现有的CSI上报方式。

其中，对于5-7中的任意一个，上报量中可以不包含CRI。
例如，所述第二上报量信息(reportQuantity1)可以是如下高层信令：
Figure PCTCN2021080310-appb-000030
或者，
Figure PCTCN2021080310-appb-000031
或者，
Figure PCTCN2021080310-appb-000032
(3)可选的，所述第三上报量信息(reportQuantity2)指示第三上报量集合中的上报量，所述第三上报量集合包含：
1、无内容；
2、CRI-RI-PMI-CQI；
3、CRI-RI-CQI；
4、CRI-RI-LI-PMI-CQI；
5、2CRI-2RI-2PMI-CQI；
6、2CRI-2RI-CQI；
7、2CRI-2RI-2LI-2PMI-CQI。
其中，第三上报量集合与第二上报量集合的内容相同。
其中，所述第三上报量集合可以不包含CRI-RI-CQI和2CRI-2RI-CQI。
其中，对于5-7中的任意一个，上报量中可以不包含CRI。
例如，所述第三上报量信息(reportQuantity2)可以是如下高层信令：
Figure PCTCN2021080310-appb-000033
Figure PCTCN2021080310-appb-000034
或者，
Figure PCTCN2021080310-appb-000035
或者，
Figure PCTCN2021080310-appb-000036
可选的，在一种实施方式中，当所述多个上报量信息均不为“无内容”时，所述多个上报量信息中至少两个上报量信息指示相同的上报量。例如，第一上报量信息指示基于NC-JT测量假设的CSI(2CRI-2RI-2PMI-CQI)，第二上报量信息和第三上报量信息均指示基于单TRP测量假设的CSI(CRI-RI-PMI-CQI)。或者，第三上报量信息指示基于NC-JT测量假设的CSI(2CRI-2RI-2PMI-CQI)，第一上报量信息和第二上报量信息均指示基于单TRP测量假设的CSI(CRI-RI-PMI-CQI)。
可选的，在一种实施方式中，当第一上报量信息指示CRI-nRI-nPMI-CQI，CRI-nRI-CQI或CRI-nRI-nLI-nPMI-CQI时，即终端设备从最好的基于单个CMR的CSI测量结果(对应的n＝1)和最好的基于多个CMR的CSI测量结果(对应的n＝2)中，选择出的其中一个最好的测量结果时，第二上报量信息只能指示“无内容”。
可选的，基于这三个上报量信息，终端设备可以在同一个CSI上报中反馈一个或多个单TRP的CSI和多TRP联合传输的CSI，从而网络设备可以根据上报的CSI进行单TRP传输和多TRP联合传输的动态切换，得到更高的下行吞吐量。其中，第一上报量信息可以用于上报基于传统的单TRP测量假设的CSI，或者上报基于多TRP的NC-JT测量假设的CSI，或者上报单TRP和NC-JT的测量假设中最好的一个测量假设对应的CSI；第二上报量信息可以用于上报基于NC-JT测量假设的CSI，或者两个TRP中最好的一个TRP的CSI，或者两个TRP其中一个TRP的CSI；第三上报量信息可以用于上报基于NC-JT测量假设的CSI，或者两个TRP中另一个TRP的CSI。
702、终端设备根据所述三个上报量信息分别测量对应的CSI。
具体的，当上报量中包含2组RI/PMI时，或者包含2组CRI/RI/PMI/CQI时(包含n＝2的情况)，两组RI/PMI或者CRI/RI/PMI/CQI分别基于不同的CMR组得到。当上报量中包含2组RI/PMI和1个CQI时，所述CQI基于两组CMR测量得到。
在一种实施方式中，所述三个上报量信息中至少两个上报量信息对应的CSI基于相同的CMR测量得到。具体的，一个CMR可以同时用于单个TRP的测量假设和NC-JT的测量假设。例如，当第一上报量信息指示CRI-2RI-2PMI-CQI或CRI-2RI-CQI或CRI-2RI-2LI-2PMI-CQI时，可以同时使用CMR集合0和CMR集合1进行CSI测量；当第二上报量信息和第三上报量信息都指示CRI-RI-PMI-CQI或CRI-RI-CQI或CRI-RI-LI-PMI-CQI时，他们对应的CSI测量分别使用CMR集合0和CMR集合1进行CSI测量。
在本实施例中，如果一个上报量信息指示无内容，则终端设备不需要测量该上报量信息对应的CSI。例如，网络设备可以配置所有的上报量信息均指示“无内容”，此时终端设备不需要进行CSI测量；或者，只配置第三上报量信息指示无内容，此时终端设备只需要测量第一和第二上报量信息对应的CSI；或者，配置第二和第三上报量信息指示无内容，此时终端设备只需要测量第一上报量信息对应的CSI。通过这种方式，这种CSI反馈方式可以回退到当前协议的CSI反馈方式，从而具备后向兼容性。
703、终端设备在同一个CSI上报中反馈所述三个上报量信息中至少一个上报量信息对应的CSI。
a)可选的，如果终端设备要反馈所述三个上报量信息分别对应的CSI，则可以将所述三个上报量信息各自对应的CSI按照所述三个上报量信息的配置顺序进行级联后，在同一个CSI上报中反馈。级联的方法可以是配置顺序在前的上报量信息对应的CSI在前。例如，假设所述三个上报量信息分别为reportQuantity0,reportQuantity1和reportQuantity2(reportQuantity0的配置顺序在前)，对应的CSI分别为CSI0，CSI1和CSI2，则终端设备将这三个CSI按照{CSI0，CSI1，CSI2}的顺序进行级联后在同一个CSI中上报。在另一种实施方式中，级联的方法也可以是配置顺序在前的上报量信息对应的CSI在后。
b)可选的，在所述CSI上报中的部分CSI需要丢弃时，按照所述三个上报量信息的配置顺序依次进行丢弃。例如，当承载所述CSI上报的PUSCH/PUCCH的码率超过一定门限时，需要丢弃其中部分的CSI，从而保证丢弃后的码率不会超过该门限。假设所述三个上报量信息分别为reportQuantity0，reportQuantity1和reportQuantity2(reportQuantity0的配置顺序在前)，对应的CSI分别为CSI0，CSI1和CSI2，则在丢弃CSI时，可以先丢弃配置顺序在后的上报量信息对应的CSI(即CSI2)，在需要时再丢弃配置顺序在前的上报量信息对应的CSI(即CSI1)，以此类推，直到码率满足门限。
c)在以上方法中，如果一个上报量信息指示无内容，则终端设备不需要上报该上报量信息对应的CSI。例如，网络设备可以配置所有的上报量信息均指示“无内容”，此时终端设备不需要上报任何CSI；或者，只配置第三上报量信息指示无内容，此时终端设备只需要上报第一和第二上报量信息对应的CSI；或者，配置第二和第三上报量信息指示无内容，则此时终端设备只需要上报第一上报量信息对应的CSI。
在本申请实施例中，可以通过在CSI上报配置中的多个上报量信息令终端设备在同一个CSI上报中反馈一个或多个单TRP的CSI和多TRP联合传输的CSI，且反馈哪几个传输假设的CSI可以灵活配置，从而网络设备可以根据上报的CSI进行单TRP传输和多TRP联合传输的动态切换，得到更高的下行吞吐量。同时，通过将一些上报量信息配置成无内容，可以保证很好的后向兼容性，回退到现有的CSI上报方式。

其中，2-4的CSI基于单个CMR进行测量得到，对应单个TRP传输需要终端设备上报的CSI内容。具体的，当第三上报量信息指示“无内容”时，2-4上报的CSI为最好的基于单个CMR的CSI测量结果 (对应于两个TRP中最好的一个单TRP的测量假设)，其中CRI用于指示推荐的一个CMR(或者CMR/IMR组合，对应于推荐的TRP)，其他CSI基于推荐的CMR(或者CMR/IMR组合)测量得到。具体的，当第三上报量信息不指示“无内容”时，2-4上报的CSI为基于一个CMR集合的CSI测量结果(对应于两个TRP中第一个TRP的测量结果)，其中CRI用于指示该CMR集合中推荐的一个CMR(或者CMR/IMR组合)，其他CSI基于推荐的CMR(或者CMR/IMR组合)测量得到；此时，第三上报量信息对应的CSI为基于另一个CMR集合的CSI测量结果(对应于两个TRP中第二个TRP的测量结果)。
其中，所述第二上报量集合可以不包含CRI-RI-CQI。
例如，所述第二上报量信息(reportQuantity1)可以是如下高层信令：

或者，
Figure PCTCN2021080310-appb-000042

1、无内容；
2、CRI-RI-PMI-CQI；
3、CRI-RI-CQI；
4、CRI-RI-LI-PMI-CQI。
其中，当第三上报量信息不指示“无内容”时，它对应的CSI为基于一个CMR集合的CSI测量结果，用于上报与第二上报量信息不同的另一个TRP的CSI(对应于两个TRP中第二个TRP的测量结果，不同TRP体现为不同的CMR集合)。
其中，所述第三上报量集合可以不包含CRI-RI-CQI。
例如，所述第三上报量信息(reportQuantity2)可以是如下高层信令：
Figure PCTCN2021080310-appb-000043
或者，
Figure PCTCN2021080310-appb-000044
在一种实施方式中，当所述多个上报量信息均不为“无内容”时，第二上报量信息与第三上报量信息指示的上报量相同。
基于这三个上报量信息，终端设备可以在同一个CSI上报中反馈一个或多个单TRP的CSI和多TRP联合传输的CSI，从而网络设备可以根据上报的CSI进行单TRP传输和多TRP联合传输的动态切换，得到更高的下行吞吐量。其中，第一上报量信息可以用于上报基于传统的单TRP测量假设的CSI，或者上报基于多TRP的NC-JT测量假设的CSI；第二上报量信息可以用于上报两个TRP中最好的一个TRP的CSI，或者两个TRP其中一个TRP的CSI；第三上报量信息可以用于上报两个TRP中另一个TRP的CSI。
802、终端设备根据所述三个上报量信息分别测量对应的CSI。

i：可选的，终端设备接收网络设备预先配置的上报类型信息，该上报类型信息可以包含在所述CSI上报配置(CSI-ReportConfig)中。终端设备根据该上报类型信息确定采用上报类型1还是上报类型2进行CSI上报，并根据确定的上报类型进行CSI上报。其中，上报类型1为分别上报所述多个上报量信息各自对应的CSI，上报类型2为从所述多个上报量信息对应的CSI中选择最佳的一个上报量信息对应的CSI进行上报。
ii：可选的，在一种实施方式中，当终端设备分别上报所述多个上报量信息各自对应的CSI时，可以将所述三个上报量信息各自对应的CSI按照所述三个上报量信息的配置顺序进行级联后，在同一个CSI上报中反馈。
iii：可选的，在一种实施方式中，当终端设备从所述多个上报量信息对应的CSI中选择最佳的一个上报量信息对应的CSI进行上报时，未选择的CSI不进行上报。如果所有上报量信息都没有指示无内容，则终端设备从三个上报量信息对应的CSI中，选择最佳的CSI进行上报；如果只配置第三上报量信息指示无内容，则终端设备从第一上报量信息和第二上报量信息对应的CSI中，选择最佳的CSI进行上报；如果第二上报量信息和第三上报量信息都指示无内容，则所述上报类型信息将不起作用。进一步的，终端设备同时上报所选择的上报量信息的指示信息，或者所选择的上报量信息对应的CSI的指示信息。例如，终端设备可以通过CSI中的1比特信息来指示当前上报的CSI是reportQuantity0对应的CSI，还是reportQuantity1对应的CSI，或者通过CSI中的2比特信息来指示当前上报的CSI是reportQuantity0，reportQuantity1还是reportQuantity2对应的CSI。如果所述CSI包含CSI部分1和CSI部分2，该指示信息可以包含在CSI部分1中。
在本申请实施例中，可以通过在CSI上报配置中的多个上报量信息令终端设备在同一个CSI上报中反馈一个或多个单TRP的CSI和多TRP联合传输的CSI，且反馈哪几个传输假设的CSI可以灵活配置，从而网络设备可以根据上报的CSI进行单TRP传输和多TRP联合传输的动态切换，得到更高的下行吞吐量。同时，通过将一些上报量信息配置成无内容，可以保证很好的后向兼容性，回退到现有的CSI上报方式。

下面结合图12对手机的各个构成部件进行具体的介绍：
RF电路1210可用于收发信息或通话过程中，信号的接收和发送，特别地，将基站的下行信息接收后，给处理器1280处理；另外，将设计上行的数据发送给基站。通常，RF电路1210包括但不限于天线、至少一个放大器、收发信机、耦合器、低噪声放大器(low noise amplifier，LNA)、双工器等。此外，RF电路1210还可以通过无线通信与网络和其他设备通信。上述无线通信可以使用任一通信标准或协议，包括但不限于全球移动通讯系统(global system of mobile communication，GSM)、通用分组无线服务(general packet radio service，GPRS)、码分多址(code division multiple access，CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、长期演进(long term evolution，LTE)、电子邮件、短消息服务(short messaging service，SMS)等。
