一种上报CSI报告的方法及装置
相关申请的交叉引用
本申请要求在2021年08月06日提交中国专利局、申请号为202110904272.4、申请名称为“一种上报CSI报告的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及无线通信领域，尤其涉及一种上报CSI报告的方法及装置。
背景技术
当前，非相干联合发送(non-coherent joint transmission，NCJT)可以实现同时由最多两个收发点(transmission reception point，TRP)为同一个终端设备提供数据传输服务。
为了支持NCJT信道状态信息(channel state information，CSI)测量假设的CSI测量，网络设备可以为终端设备配置由K个参考信号资源组成参考信号资源集合。其中，参考信号资源可以是非零功率信道状态信息参考信号(non-Zero power channel state information reference signal，NZP CSI-RS)资源。网络设备还配置了干扰测量资源集合，干扰测量集合中包含信道状态信息干扰测量(Channel state information-interference measurement，CSI-IM)资源。
网络设备可以进一步在K个参考信号资源中，配置N个信道测量资源对(channel measurement resource pair，CMR pair)，N为正整数，每个信道测量资源对包括2个参考信号资源，其中，参考信号资源与TRP具有关联关系，不同参考信号资源关联的TRP不同。网络设备还可以配置与N个信道测量资源对分别关联的干扰测量资源，终端设备可以在每个信道测量资源对所包括的2个参考信号资源及其关联的1个干扰测量资源上，按照NCJT CSI测量假设进行CSI计算。其中，N个信道测量资源对对应N个NCJT CSI测量假设。
网络设备还可以进一步在K个参考信号资源中，配置M(M≤K)个参考信号资源，以及与M个参考信号资源分别关联的干扰测量资源，终端设备可以在每个参考信号资源及其关联的干扰测量资源上，按照单TRP CSI测量假设进行CSI计算。其中，M个参考信号资源对应M个单TRP测量假设。
上述配置中，网络设备可以为终端设备配置1个参考信号资源集合和1个干扰测量资源集合，参考信号资源集合中所包括的参考信号资源个数与干扰测量资源集合中所包括的干扰测量资源个数相同，并且参考信号资源集合中的参考信号资源按照其在集合中的顺序与干扰测量资源集合中的干扰测量资源按照其在干扰测量资源集合中的顺序对应。
由于网络设备在K个参考信号资源中配置M个参考信号资源时，M的取值可以不同，因此，不同M的取值导致干扰测量资源集合中所包括的干扰测量资源个数不同，即对应每个M的取值都需要单独关联1个的干扰测量资源集合，进而将会导致需要对应不同M的取值分别配置干扰测量资源集合，造成配置参数急剧增加，配置效率较低。
发明内容
本申请实施例提供一种上报CSI报告的方法及装置，用以解决对应不同M的取值分别配置干扰测量资源集合造成配置参数急剧增加的问题。
第一方面，本申请实施例提供一种上报CSI报告的方法，该方法的执行主体可以为终端设备或用于实现终端设备的功能的装置，以下以执行主体为终端设备为例进行说明。该方法包括：终端设备接收第一配置信息和第二配置信息，确定N个信道测量资源对，获得CSI报告，向网络设备发送CSI报告。其中，所述第一配置信息关联参考信号资源的配置信息，所述参考信号资源的配置信息配置参考信号资源集合和干扰测量资源集合，其中，所述参考信号资源集合包括K个参考信号资源，所述干扰测量资源集合包括X个干扰测量资源；N是大于等于1的整数，其中，每个信道测量资源对包含P个参考信号资源，且每个信道测量资源对包含的P个参考信号资源都属于所述参考信号资源集合，P是大于等于2的整数，K是大于等于P的整数，所述X满足X＝N+K；所述第二配置信息指示K个参考信号资源中的M个参考信号资源，M为小于等于K的正整数；所述干扰测量资源集合包括的X个干扰测量资源与所述K个参考信号资源和所述N个信道测量资源对具有第一关联关系；或者，所述干扰测量资源集合包括的X个干扰测量资源中M+N个干扰测量资源与所述M个参考信号资源和所述N个信道测量资源对具有第二关联关系；所述CSI报告与所述M个参考信号资源及其关联的M个所述干扰测量资源、所述N个信道测量资源对所包含的参考信号资源及其关联的N个所述干扰测量资源具有关联关系。
采用上述方法解决了在NCJT CSI测量假设下，与参考信号资源集合关联的干扰测量资源集合中配置的干扰测量资源数量如何配置，以及干扰测量资源集合中干扰测量资源如何与用于单TRP CSI测量假设的参考信号资源和用于NCJT CSI测量假设的信道测量资源对如何关联的问题。其中，干扰测量资源集合包含X个干扰测量资源，其中X＝N+K，进而可以实现即使M的取值不同，同一个参考信号资源集合关联的干扰测量资源集合也是相同，可以实现有效减轻配置资源的复杂度以及终端设备的存储负担。
在一种可能的设计中，所述第一配置信息是CSI报告配置信息，所述CSI报告配置信息包括所述第二配置信息。
在一种可能的设计中，所述第二配置信息包括K比特，所述K比特按顺序与所述K个参考信号资源对应。
采用上述设计可以实现指示每个参考信号资源是否为K个参考信号资源中的M个参考信号资源，进而可以确定M的取值。
在一种可能的设计中，所述第二配置信息指示所述N个信道测量资源对对应的参考信号资源是否用于单TRP CSI测量假设的CSI测量。
采用上述设计可以实现指示N个信道测量资源对对应的参考信号资源是否用于单TRP CSI测量假设的CSI测量，进而可以确定M的取值。
在一种可能的设计中，所述干扰测量资源集合包括的X个干扰测量资源与所述K个参考信号资源和所述N个信道测量资源对具有第一关联关系是指：所述干扰测量资源集合中的前K个干扰测量资源按所述K个干扰资源在所述干扰测量资源集合中的顺序与所述K个参考信号资源按所述K个参考信号资源在所述参考信号资源集合中的顺序关联，且所述干扰测量资源集合中的最后N个干扰测量资源按所述N个干扰资源在所述干扰测量资源集合中的顺序和所述N个信道测量资源对按所述N个信道测量资源对在所述参考信号资源集 合中的顺序关联；或者，所述干扰测量资源集合中的前N个干扰测量资源按所述N个干扰资源在所述干扰测量资源集合中的顺序与所述N个信道测量资源对按所述N个信道测量资源对在所述参考信号资源集合中的顺序关联，且所述干扰测量资源集合中的最后K个干扰测量资源按所述K个干扰资源在所述干扰测量资源集合中的顺序和所述K个参考信号资源按所述K个参考信号资源对在所述参考信号资源集合中的顺序关联。
采用上述第一关联关系可以实现即使第二配置信息指示的M的取值不同，也不会改变同一个干扰测量资源所关联的参考信号资源或信道测量资源对，有利于干扰测量的准确性。尤其是当干扰测量资源是周期的或半持续的资源时，终端设备往往会进行时域滤波，在同一个干扰测量资源所关联的参考信号资源或信道测量资源对不变时，有利于滤波的性能，提高干扰估计的准确性。

示例性地，如图2B所示，2个TRP中只有1个TRP发射1个DCI，调度1个PDSCH，但是这个PDSCH中的部分的流/层(对应一部分解调参考信号(demodulation reference signal，DMRS)端口)由一个TRP发射，另一部分流/层(对应另一部分DMRS端口)由另一个TRP发射。具体的，TRP1向UE发送DCI1，调度第一组流/层/DMRS端口向UE发送数据1，TRP2调度另一组流/层/DMRS端口向UE发送数据2，上述两组流/层/DMRS端口属于DCI1调度的PDSCH1。此外，还可以由TRP2向UE发送DCI1，此处仅以TRP1发送DCI1为例进行说明，不作为本申请的限定。
2.单TRP CSI测量假设
在新空口(new radio，NR)的前期版本(例如，版本15(Release-15)和Release-16)中，CSI测量都是基于单TRP CSI测量假设的，即UE在CSI测量时，假设后续的数据发送来自于1个TRP，UE在一个参考信号资源及其关联的1个干扰测量资源上进行CSI测量，得到CSI报告。
在无线通信过程中，网络设备(例如TRP)获取CSI报告的具体过程如下：
网络设备在参考信号资源上发射信道状态探测信号，例如，在NR中，信道状态探测信号可以采用NZP CSI-RS。
UE在预先配置的参考信号资源上接收信道状态探测信号进行信道估计。此外，TRP还会进一步为UE配置一组与参考信号资源对应的干扰测量资源，每个参考信号资源与1个干扰测量资源关联，UE在这些预先配置的干扰测量资源上接收信号，进行干扰测量。UE基于在1个参考信号资源上获得的信道测量结果和在1个关联的干扰测量资源上获得的干扰测量结果，计算出1个CSI，当配置的一组参考信号资源包含多个参考信号资源时，UE可以在这多个参考信号资源及其关联的多个干扰测量资源上计算出多个CSI，UE从中选择1个CSI组成CSI报告，UE通过上行信道发送CSI报告给TRP。
进一步地，网络设备可以根据各个UE反馈的CSI报告进行调度，例如，在PDSCH上向UE发送下行数据。
需要说明的是，在NR协议中，网络设备为UE配置参考信号资源和干扰测量资源， UE基于参考信号资源上的信号和干扰测量资源上的信号分别进行对应的信道测量和干扰测量，而为了简化描述，在本申请实施例中将上述过程简化描述为：UE在参考信号资源和干扰测量资源上进行CSI测量。
3.NCJT CSI测量假设
在Release-16引入NCJT发送模式后，Release-15和Release-16的CSI测量将无法很好的支持NCJT发送模式的测量需要。为此，在版本17(Release-17)中，对现有的CSI测量进行增强，以能够支持NCJT CSI测量假设的CSI测量。其中，NCJT CSI测量假设是指UE在CSI测量时，假设后续的数据发送来自于2个TRP，UE在一个信道测量资源对及其关联的干扰测量资源上进行CSI测量，得到CSI报告。
从配置的角度来看，一个信道测量资源对所对应的2个参考信号资源会关联2个不同的传输配置指示状态(Transmission configuration indicator state，TCI state)信息，每个TCI状态信息中包含了与该TCI状态信息关联的参考信号资源的准共站(quasi co-location，QCL)信息。UE根据TCI状态信息所包含的QCL信息接收对应的参考信号资源上的参考信号。因此，对于UE而言，只需要知道QCL信息而并不一定要知道参考信号资源到底与哪个TRP关联。对于网络设备而言，网络设备也只需要为信道测量资源对所对应的2个参考信号资源配置包含不同QCL信息的TCI状态信息，即与2个参考信号资源关联的2个TCI状态信息所包含的QCL信息关联的TRP不同。
可以理解的是，本申请实施例以每个信道测量资源对包括2个参考信号资源为例进行说明，随着技术演进，每个信道测量资源对可能包括2个以上参考信号资源，信道测量资源对也可以替换为其他名称，例如参考信号资源子集等，本申请实施例对此不作限定，这里仅以每个信道测量资源对包括2个参考信号资源为例进行说明。
4.CSI报告
为了匹配单TRP CSI测量假设和NCJT CSI测量假设，网络设备配置UE在一个CSI报告包含的内容可以为如下两种选项：
选项1：m个单TRP CSI测量假设对应的CSI和1个NCJT CSI测量假设对应的CSI，其中，m的取值可以为0、1、2。
选项2：1个CSI，该CSI可以是单TRP CSI测量假设对应的CSI或者NCJT CSI测量假设对应的CSI。
示例性地，当K个参考信号资源中配置用于支持NCJT CSI测量假设的N个信道测量资源对和用于支持单TRP测量假设的M个参考信号资源时，UE可以在每个参考信号资源和对应的干扰测量资源上分别进行CSI测量，获得M个单TRP CSI测量假设对应的CSI。同理，UE可以在每个信道测量资源对与对应的干扰测量资源上分别进行CSI测量，获得N个NCJT CSI测量假设对应的CSI。
对应于上述选项1，UE从M个单TRP CSI测量假设对应的CSI中选择m个单TRP CSI测量假设对应的CSI，并从N个NCJT CSI测量假设对应的CSI中选择1个NCJT CSI测量假设对应的CSI。UE向网络设备发送m个单TRP CSI测量假设对应的CSI和1个NCJT CSI测量假设对应的CSI。
对应于上述选项2，UE从M个单TRP CSI测量假设对应的CSI中选择1个单TRP CSI测量假设对应的CSI，或者从N个NCJT CSI测量假设对应的CSI中选择1个NCJT CSI测量假设对应的CSI。UE向网络设备发送1个单TRP CSI测量假设对应的CSI或1个NCJT  CSI测量假设对应的CSI。
其中，CSI包括CSI-RS资源指示信息(CSI-RS resource indicator，CRI)、秩指示(rank indicator，RI)信息、信道质量指示(channel quality indicator，CQI)信、预编码矩阵指示(precoding matrix indicator，PMI)PMI、层指示(LI，Layer indicator)信息中的一项或多项。其中，CRI用于指示一个参考信号资源或一个信道测量资源对；RI，用于指示秩值；CQI，用于指示信道质量；PMI，用于指示预编码矩阵信息；LI，用于指示层信息。可以理解的是，CSI具体包括上述哪些项信息是基于网络配置决定的。
为了解决对应不同M的取值分别配置干扰测量资源集合造成配置参数急剧增加的问题，本申请实施例提供一种上报CSI报告的方法，如图3所示，该方法包括：
步骤300：网络设备向终端设备发送第一配置信息和第二配置信息。
其中，第一配置信息关联参考信号资源的配置信息，参考信号资源的配置信息配置参考信号资源集合和干扰测量资源集合，其中，参考信号资源集合包括K个参考信号资源，干扰测量资源集合包括X个干扰测量资源。第二配置信息指示K个参考信号资源中的M个参考信号资源，M为小于等于K的正整数，M个参考信号资源对应单TRP CSI测量假设。
示例性地，参考信号资源可以为NZP CSI-RS资源，干扰测量资源可以为CSI-IM资源。
步骤310：终端设备确定N个信道测量资源对，N是大于等于1的整数，其中，每个信道测量资源对包含P个参考信号资源，且每个信道测量资源对包含的P个参考信号资源都属于参考信号资源集合，P是大于等于2的整数，K是大于等于P的整数，X满足X＝N+K；
其中，N个信道测量资源对对应NCJT CSI测量假设。
示例性地，在通常情况下，信道测量资源对对应P＝2的情况，即每个信道测量资源对包括2个参考信号资源。而当P＞2时，信道测量资源对也可以描述为参考信号资源子集，或其他名称，本申请实施例对此不作限定，本申请实施例仅以信道测量资源对包括2个参考信号资源为例进行说明。
在一些实现方式中，在参考信号资源集合包括的K个参考信号资源为K个参考信号资源时，终端设备根据参考信号资源的配置信息从K个参考信号资源中确定N个信道测量资源对，N是大于等于1的整数，每个信道测量资源对包含2个NZP CSI-RS资源。在K个参考信号资源中确定信道测量资源对包含的2个参考信号资源可以采用但不限于如下方式：
示例1：终端设备根据网络设备发送的第一信令，在K个参考信号资源中确定信道测量资源对。
例如，第一信令可以指示信道测量资源对的数量N、和N个包括K个比特的比特图，每个比特图中有2个比特位上的值是“0”，表示参考信号资源集合中对应的参考信号资源可以被用于作为信道测量资源对中的参考信号资源，其他比特位上的值是“1”，表示参考信号资源集合中对应的参考信号资源不可以被用于作为信道测量资源对中的参考信号资源。或者，每个比特图中有2个比特位上的值是“1”，表示参考信号资源集合中对应的参考信号资源可以被用于作为信道测量资源对中的参考信号资源，其他比特位上的值是“0”，表示参考信号资源集合中对应的参考信号资源不可以被用于作为信道测量资源对中的参考信号资源。
例如，参考信号资源集合包含4(即K＝4)个参考信号资源，分别为{#0，#1，#2， #3}。上述信令指示N＝1和1个比特图，该比特图的取值为0011，#0和#1所对应的参考信号资源，组成1个信道测量资源对。
示例2：终端设备根据预先规则，在K个参考信号资源中确定信道测量资源对。
例如，预设规则可以是：当参考信号资源集合包含2(K＝2)个参考信号资源时，这两个参考信号资源组成1个信道测量资源对。例如这两个参考信号资源分别为{#0，#1}，则#0和#1所对应的参考信号资源组成1个信道测量资源对。
预设规则还可以是：K个参考信号资源中的相邻两个参考信号资源组合成一个信道测量资源对。例如，参考信号资源集合包含4(K＝4个)参考信号资源，{#0，#1，#2，#3}，则#0和#1参考信号资源组成一个信道测量资源对，#2和#3参考信号资源组成另一个信道测量资源对。
示例3：示例1和示例2结合，确定信道测量资源对。
例如根据第一信令和预先规则在K个参考信号资源中确定信道测量资源对。
例如，第一信令指示信道测量资源对的数量N，预设规则可以是：K个参考信号资源中的前2N个参考信号资源相邻的两个(也可以理解为按两两)组合成N个信道测量资源对。例如，参考信号资源集合包含6(K＝6个)参考信号资源，{#0，#1，#2，#3，#4，#5}，第一信令指示N＝2，则#0和#1参考信号资源组成一个信道测量资源对，#2和#3参考信号资源组成另一个信道测量资源对。
以下对第一配置信息做进一步说明：
示例性地，第一配置信息是CSI报告配置信息，CSI报告配置信息包括第二配置信息。例如，在NR中，CSI报告配置信息可以是RRC信令CSI测量配置(CSI-MeasConfig)，或者是CSI报告配置信息可以是RRC信令CSI报告配置(CSI-ReportConfig)。
在一些实施例中，CSI报告配置信息包括参考信号资源的配置信息，参考信号资源的配置信息用于确定参考信号资源集合和干扰测量资源集合。
在一示例中，参考信号资源的配置信息可以是RRC信令NZP-CSI-RS资源集合(NZP-CSI-RS-ResourceSet)和CSI-IM资源集合(CSI-IM-ResourceSet)，其中，前者用于确定参考信号资源集合，后者用于确定干扰测量资源集合，例如，参考信号资源集合是NZP CSI-RS资源集合，干扰测量资源集合是CSI-IM资源集合。
在另一示例中，参考信号资源的配置信息可以是RRC信令NZP-CSI-RS-ResourceSet和CSI-IM-ResourceSet，其中，参考信号资源的配置信息包含了2个NZP-CSI-RS-ResourceSet，1个NZP-CSI-RS-ResourceSet用于确定参考信号资源集合，另一个NZP-CSI-RS-ResourceSet和CSI-IM-ResourceSet用于确定2个干扰测量资源集合，其中，NZP-CSI-RS-ResourceSet确定的干扰测量资源集合包含NZP CSI-RS资源，用于测量多用户干扰，CSI-IM-ResourceSet确定的干扰测量资源集合包含CSI-IM资源，用于测量邻小区干扰。
可以理解的是，在NCJT CSI测量假设中，已经排除了基于NZP CSI-RS资源的干扰测量。本申请实施例仅以干扰测量资源集合是CSI-IM资源集合为例进行说明，此外，对于干扰测量资源集合还包括NZP CSI-RS资源集合的情况，本申请实施例提供的方法同样适用。
以下对第二配置信息的可能实现方式进行说明：
方式1：第二配置信息包括K比特，K比特与K个参考信号资源对应。
例如，第二配置信息是1个K比特的比特位图，每个比特对应1个参考信号资源、对于任一个比特，当该比特的取值为1时，该比特对应的参考信号资源为单TRP CSI测量假设对应的参考信号资源，或者，该比特对应的参考信号资源用于单TRP CSI测量假设的CSI测量，当该比特的取值为0时，该比特对应的参考信号资源不是单TRP CSI测量假设对应的参考信号资源，或者，该比特对应的参考信号资源不用于单TRP CSI测量假设的CSI测量。
例如，在K＝4时，参考信号资源集合包括参考信号资源1至参考信号资源4，其中，参考信号资源1和参考信号资源2对应于TRP1，参考信号资源3和参考信号资源4对应于TRP2，1个信道测量资源对包括参考信号资源1和参考信号资源3。第二配置信息包括4比特信息，其中，第1个比特用于指示参考信号资源1是否为单TRP CSI测量假设对应的参考信号资源，第2个比特用于指示参考信号资源2是否为单TRP CSI测量假设对应的参考信号资源，第3个比特用于指示参考信号资源3是否为单TRP CSI测量假设对应的参考信号资源，第4个比特用于指示参考信号资源4是否为单TRP CSI测量假设对应的参考信号资源。
方式2：第二配置信息指示N个信道测量资源对对应的参考信号资源是否用于单收发点TRP CSI测量假设的CSI测量。
例如，第二配置信息包括1比特信息，当该比特的取值为1时，表示使能N个信道测量资源对所对应的参考信号资源用于单TRP CSI测量假设的CSI测量，此时，M＝K。当该比特的取值为0时，表示未使能N个信道测量资源对所对应的参考信号资源用于单TRP CSI测量假设的CSI测量，此时，M＝K-2N。
例如，在K＝4时，参考信号资源集合包括参考信号资源1至参考信号资源4，其中，参考信号资源1和参考信号资源2对应于TRP1，参考信号资源3和参考信号资源4对应于TRP2，1个信道测量资源对包括参考信号资源1和参考信号资源3。当第二配置信息包括1比特信息，当该比特的取值为1时，参考信号资源1、参考信号资源2、参考信号资源3和参考信号资源4均可以用于单TRP CSI测量假设的CSI测量，当第二配置信息包括1比特信息，当该比特的取值为0时，参考信号资源2和参考信号资源4可以用于单TRP CSI测量假设的CSI测量，参考信号资源1和参考信号资源3不可以用于单TRP CSI测量假设的CSI测量，仅用于NCJT CSI测量假设的CSI测量。
可以理解的是，由于第二配置信息确定的M的取值直接决定了单TRP CSI测量假设的参考信号资源的数量，而在终端设备后续上报CSI报告时，CSI包括的CRI用于指示CSI所关联的测量资源，而CRI的比特长度或者负载将受到单TRP CSI测量假设数量的影响，也就是说，M的取值直接影响后续CSI报告的比特长度或负载。例如，在K＝4，M＝2时，CRI指示M个参考信号资源中的一个参考信号资源需要1比特，在K＝4，M＝4时，CRI指示M个参考信号资源中的一个参考信号资源需要2比特，在K＝8，M＝6时，CRI指示M个参考信号资源中的一个参考信号资源需要3比特。
因此，当第一配置信息是CSI报告配置信息，CSI报告配置信息包括第二配置信息时，一个CSI报告配置信息指示的CSI报告配置参数对应一种CSI报告的比特长度或负载，有利于标准的制定和产品的实现。
可以理解的是，在参考信号资源集合所包含的K个参考信号资源中，M个参考信号资源需要进行单TRP CSI测量假设的CSI测量，N个信道测量资源对需要进行NCJT CSI测 量假设的CSI测量。由于每个测量假设需要一个CSI-IM资源，正常来说，干扰测量资源集合包含X个CSI-IM资源，只需要X＝M+N就足够了。但是，在CSI报告配置信息中，CSI报告配置信息与参考信号资源的配置信息配置的参考信号资源集合和干扰测量资源集合关联。当两个CSI报告配置信息所包含的CSI报告配置参数中除了M的取值的配置参数不同(即第二配置信息不同)，而其他配置参数相同时，这两个CSI报告配置信息可以与同一个包含了K个参考信号资源的参考信号资源集合关联，以及与相同的N个信道测量资源对关联。由于第二配置信息包含在是在CSI报告配置信息中，在M的取值不同时，若干扰测量资源集合包含的CSI-IM资源数量按照X＝M+N来配置，同一个参考信号资源集合根据两个CSI报告配置信息会关联两个不同的干扰测量资源集合，因此，将会大大增加干扰测量资源集合配置数量，增加终端设备的存储负担。因此，在本申请实施例中，干扰测量资源集合包含X个CSI-IM资源，其中X＝N+K，进而可以实现即使M的取值不同，同一个参考信号资源集合关联的干扰测量资源集合也是相同，可以实现有效减轻配置资源的复杂度以及终端设备的存储负担。
以下对干扰测量资源集合和参考信号资源集合的关联关系进行说明：
需要说明的是，本申请实施例中参考信号资源在参考信号资源集合中的顺序可以理解为，该参考信号资源的标识在参考信号资源集合的配置信息中出现的顺序。同理，干扰测量资源在干扰测量资源集合中的顺序可以理解为，该干扰测量资源的标识在干扰测量资源集合的配置信息中出现的顺序。
在一种实现方式中，干扰测量资源集合包括的X个干扰测量资源与K个参考信号资源和N个信道测量资源对具有第一关联关系。
示例性地，第一关联关系的第一种实现方式为：第一关联关系可以是指干扰测量资源集合中的前K个干扰测量资源与K个参考信号资源关联，所述关联是按照前K个干扰测量资源在干扰资源集合中的顺序和K个参考信号资源在参考信号资源集合中的顺序，K个干扰测量资源与K个参考信号资源关联；且干扰测量资源集合中的最后N个干扰测量资源与N个信道测量资源对关联，所述关联是按照最后N个干扰测量资源在干扰资源集合中的顺序和N个信道测量资源对在参考信号资源集合中的顺序，N个干扰测量资源与N个信道测量资源对关联。需要注意的是，上述示例中，参考信号资源在参考信号资源集合中的顺序与参考信号资源的序号无关，干扰测量资源在干扰资源集合中的顺序与干扰资源的序号无关，同样的，信道测量资源对在参考信号资源集合中的顺序与信道测量资源对的序号无关。
第一关联关系的第二种实现方式为：第一关联关系可以是指干扰测量资源集合中的前N个干扰测量资源与N个信道测量资源对关联，所述关联是按照前N个干扰测量资源在干扰资源集合中的顺序和N个信道测量资源对在参考信号资源集合中的顺序，N个干扰测量资源与N个参考信号资源关联；且干扰测量资源集合中的最后K个干扰测量资源与K个参考信号资源关联，所述关联是按照最后K个干扰测量资源在干扰资源集合中的顺序和K个参考信号资源在参考信号资源集合中的顺序，K个干扰测量资源与K个参考信号资源对关联。
以下仅第一关联关系的第一种实现方式为例进行说明。
如图4A和图4B所示，参考信号资源集合包含4个参考信号资源，K＝4，其中，第1个参考信号资源和第3个参考信号资源组成信道测量资源对，N＝1。相应的干扰测量资源 集合中包含5个干扰测量资源，X＝K+N＝5。
示例性地，4个参考信号资源的标识在参考信号资源集合的配置信息中出现的顺序可以为NZP-CSI-RS-ResourceId＝12、NZP-CSI-RS-ResourceId＝8、NZP-CSI-RS-ResourceId＝14、NZP-CSI-RS-ResourceId＝6。
5个干扰测量资源的标识在干扰测量资源集合的配置信息中出现的顺序可以为CSI-IM-ResourceId＝5、CSI-IM-ResourceId＝4、CSI-IM-ResourceId＝2、CSI-IM-ResourceId＝10，CSI-IM-ResourceId＝6。
参考信号资源集合中4个参考信号资源与干扰测量资源集合中的前4个干扰测量资源，按照4个参考信号资源在参考信号资源集合中的顺序和前4个干扰测量资源在干扰测量资源集合中的顺序关联。即参考信号资源集合中的第1个参考信号资源(对应的NZP-CSI-RS-ResourceId为12)与干扰测量资源集合中的第1个干扰测量资源(对应的CSI-IM-ResourceId为5)具有关联关系，参考信号资源集合中的第2个参考信号资源(对应的NZP-CSI-RS-ResourceId为8)与干扰测量资源集合中的第2个干扰测量资源(对应的CSI-IM-ResourceId为4)具有关联关系，参考信号资源集合中的第3个参考信号资源(对应的NZP-CSI-RS-ResourceId为14)与干扰测量资源集合中的第3个干扰测量资源(对应的CSI-IM-ResourceId为2)具有关联关系，参考信号资源集合中的第4个参考信号资源(对应的NZP-CSI-RS-ResourceId为6)与干扰测量资源集合中的第4个干扰测量资源(对应的CSI-IM-ResourceId为10)具有关联关系；参考信号资源集合中信道测量资源对与干扰测量资源集合中的最后N＝1个干扰测量资源按顺序具有关联关系，即信道测量资源对与最后1个也就是第5个干扰测量资源(对应的CSI-IM-ResourceId为6)具有关联关系。
示例性地，在第二配置信息指示4个参考信号资源用于单TRP测量假设的CSI测量时，例如，第二配置信息包括1比特信息，该比特的取值为1，表示使能1个信道测量资源对所包含的参考信号资源用于单TRP测量假设的CSI测量，如上所述，每个参考信号资源与所关联的干扰测量资源如图4A所示。
示例性地，在第二配置信息指示2个参考信号资源用于单TRP测量假设的CSI测量时，例如，第二配置信息包括1比特信息，该比特的取值为0，表示使能1个信道测量资源对所包含的参考信号资源不用于单TRP测量假设的CSI测量。用于单TRP测量假设的参考信号资源就只剩下第2个参考信号资源和第4个参考信号资源，如上所述，参考信号资源集合中的第2个参考信号资源(对应的NZP-CSI-RS-ResourceId为8)与干扰测量资源集合中的第2个干扰测量资源(对应的CSI-IM-ResourceId为4)具有关联关系，参考信号资源集合中的第4个参考信号资源(对应的NZP-CSI-RS-ResourceId为6)与干扰测量资源集合中的第4个干扰测量资源(对应的CSI-IM-ResourceId为10)具有关联关系，参考信号资源集合中信道测量资源对与干扰测量资源集合中的最后N＝1个干扰测量资源按顺序具有关联关系，即信道测量资源对与最后1个也就是第5个干扰测量资源(对应的CSI-IM-ResourceId为6)具有关联关系，如图4B所示。
采用第一关联关系，即使第二配置信息指示的M的取值不同，也不会改变同一个干扰测量资源所关联的参考信号资源或信道测量资源对，有利于干扰测量的准确性。尤其是当干扰测量资源是周期的或半持续的资源时，终端设备往往会进行时域滤波，在同一个干扰测量资源所关联的参考信号资源或信道测量资源对不变时，有利于滤波的性能，提高干扰估计的准确性。
在另一种实现方式中，干扰测量资源集合包括的X个干扰测量资源中M+N个干扰测量资源与M个参考信号资源和N个信道测量资源对具有第二关联关系。
示例性地，第二关联关系的第一种实现方式为：第二关联关系可以是指所述干扰测量资源集合中的前M个干扰测量资源与M个参考信号资源关联，所述关联是按照前M个干扰测量资源在干扰资源集合中的顺序和M个参考信号资源在参考信号资源集合中的顺序，M个干扰测量资源与M个参考信号资源关联；且干扰测量资源集合中的最后N个干扰测量资源与N个信道测量资源对关联，所述关联是按照最后N个干扰测量资源在干扰资源集合中的顺序和N个信道测量资源对的顺序，N个干扰测量资源与N个信道测量资源对关联。
第二关联关系的第二种实现方式为：第二关联关系可以是指所述干扰测量资源集合中的前N个干扰测量资源与N个参考信号资源对关联，所述关联是按照前N个干扰测量资源在干扰资源集合中的顺序和N个参考信号资源对的顺序，N个干扰测量资源与N个参考信号资源对关联；且干扰测量资源集合中的最后M个干扰测量资源与M个信道测量资源关联，所述关联是按照最后M个干扰测量资源在干扰资源集合中的顺序和M个信道测量资源在参考信号资源集合中的顺序，M个干扰测量资源与M个信道测量资源关联。
以下仅第二关联关系的第一种实现方式为例进行说明。
如图4A和图5所示，参考信号资源集合包含4个参考信号资源，K＝4，其中，第1个参考信号资源和第3个参考信号资源组成信道测量资源对，N＝1。相应的干扰测量资源集合中包含5个干扰测量资源，X＝K+N＝5。
示例性地，4个参考信号资源的标识在参考信号资源集合的配置信息中出现的顺序可以为NZP-CSI-RS-ResourceId＝12、NZP-CSI-RS-ResourceId＝8、NZP-CSI-RS-ResourceId＝14、NZP-CSI-RS-ResourceId＝6。
5个干扰测量资源的标识在干扰测量资源集合的配置信息中出现的顺序可以为CSI-IM-ResourceId＝5、CSI-IM-ResourceId＝4、CSI-IM-ResourceId＝2、CSI-IM-ResourceId＝10，CSI-IM-ResourceId＝6。
示例性地，在第二配置信息指示4个参考信号资源用于单TRP测量假设的CSI测量时，例如，第二配置信息包括1比特信息，该比特的取值为1，表示使能1个信道测量资源对所包含的参考信号资源用于单TRP测量假设的CSI测量，每个参考信号资源与所关联的干扰测量资源如图4A所示。参考信号资源集合中4个参考信号资源与干扰测量资源集合中的前4个干扰测量资源，按照4个参考信号资源在参考信号资源集合中的顺序和前4个干扰测量资源在干扰测量资源集合中的顺序关联。即参考信号资源集合中的第1个参考信号资源(对应的NZP-CSI-RS-ResourceId为12)与干扰测量资源集合中的第1个干扰测量资源(对应的CSI-IM-ResourceId为5)具有关联关系，参考信号资源集合中的第2个参考信号资源(对应的NZP-CSI-RS-ResourceId为8)与干扰测量资源集合中的第2个干扰测量资源(对应的CSI-IM-ResourceId为4)具有关联关系，参考信号资源集合中的第3个参考信号资源(对应的NZP-CSI-RS-ResourceId为14)与干扰测量资源集合中的第3个干扰测量资源(对应的CSI-IM-ResourceId为2)具有关联关系，参考信号资源集合中的第4个参考信号资源(对应的NZP-CSI-RS-ResourceId为6)与干扰测量资源集合中的第4个干扰测量资源(对应的CSI-IM-ResourceId为10)具有关联关系；参考信号资源集合中信道测量资源对与干扰测量资源集合中的最后N＝1个干扰测量资源按顺序具有关联关系，即信道测量资源对与最后1个也就是第5个干扰测量资源(对应的CSI-IM-ResourceId为6)具有关联 关系。
示例性地，在第二配置信息指示2个参考信号资源用于单TRP测量假设的CSI测量时，例如，第二配置信息包括1比特信息，该比特的取值为0，表示使能1个信道测量资源对所包含的参考信号资源不用于单TRP测量假设的CSI测量。用于单TRP测量假设的参考信号资源就只剩下第2个参考信号资源和第4个参考信号资源。
如图5所示，参考信号资源集合中第2个参考信号资源和第4个参考信号资源与干扰测量资源集合中的前2个干扰测量资源，按照第2个参考信号资源和第4个参考信号资源在参考信号资源集合中的顺序和前2个干扰测量资源在干扰测量资源集合中的顺序关联。即参考信号资源集合中的第2个参考信号资源(对应的NZP-CSI-RS-ResourceId为8)与干扰测量资源集合中的第1个干扰测量资源(对应的CSI-IM-ResourceId为5)具有关联关系，参考信号资源集合中的第4个参考信号资源(对应的NZP-CSI-RS-ResourceId为6)与干扰测量资源集合中的第2个干扰测量资源(对应的CSI-IM-ResourceId为4)具有关联关系；参考信号资源集合中信道测量资源对与干扰测量资源集合中的最后N＝1个干扰测量资源按顺序具有关联关系，即信道测量资源对与最后1个也就是第5个干扰测量资源(对应的CSI-IM-ResourceId为6)具有关联关系。
采用第二关联关系，在第二配置信息指示N个信道测量资源对包含的参考信号资源不用于单TRP CSI测量假设的CSI测量时，用于单TRP CSI测量假设的CSI测量的M个参考信号资源所关联的干扰测量资源是连续的，由于CRI需要与干扰测量资源具有关联关系，因此可以降低CRI反馈的比特数。同时，同一个干扰测量资源与用于单TRP测量假设的CSI测量的参考信号资源具有关联关系，或者与用于NCJT CSI测量假设的CSI测量的参考信号资源具有关联关系。
步骤320：终端设备获得CSI报告。
其中，CSI报告与M个参考信号资源及其关联的M个干扰测量资源、N个信道测量资源对所包含的参考信号资源及其关联的N个干扰测量资源具有关联关系。
示例性地，CSI报告包括参考信号资源指示信息和CSI测量信息，其中，参考信号资源指示信息的比特长度由K和N确定；或者，参考信号资源指示信息的比特长度由M和N确定。
例如，对应于第一种关联关系，参考信号资源指示信息的比特长度可以由K和N确定。此外，对应于第一种关联关系，参考信号资源指示信息的比特长度还可以由M和N确定。
例如，对应于第二种关联关系，参考信号资源指示信息的比特长度可以由M和N确定。此外，对应于第二种关联关系，参考信号资源指示信息的比特长度还可以由K和N确定。
CSI测量信息包括PMI信息、CQI信息、RI信息、LI信息中的一种或多种。
在一种实现方式中，参考信号资源指示信息是第一参考信号资源指示信息；CSI测量信息是第一CSI测量信息。第一参考信号资源指示信息与第一信道测量资源对具有关联关系，第一信道测量资源对是N个信道测量资源对中的一个信道测量资源对，第一参考信号资源指示信息与第一干扰测量资源具有关联关系，第一干扰测量资源是第一信道测量资源对所关联的一个干扰测量资源。第一CSI测量信息是在第一信道测量资源对包含的P个参考信号资源和第一干扰测量资源上测量获得的。
在一种实现方式中，参考信号资源指示信息是第二参考信号资源指示信息；CSI测量 信息是第二CSI测量信息。第二参考信号资源指示信息与第一参考信号资源具有关联关系，第一参考信号资源是M个参考信号资源中的一个参考信号资源，第二参考信号资源指示信息与第二干扰测量资源具有关联关系，第二干扰测量资源是第一参考信号资源所关联的一个干扰测量资源。第二CSI测量信息是在第一参考信号资源和第二干扰测量资源上测量获得的。
在一种实现方式中，参考信号资源指示信息是第三参考信号资源指示信息和第四参考信号资源指示信息，CSI测量信息是第三CSI测量信息和第四CSI测量信息。
第三参考信号资源指示信息与第二信道测量资源对具有关联关系，第三信道测量资源对是N个信道测量资源对中的一个信道测量资源对；第三参考信号资源指示信息与第三干扰测量资源具有关联关系，第三干扰测量资源是第二信道测量资源对所关联的一个干扰测量资源。第三CSI测量信息是在第二信道测量资源对包含的P个参考信号资源和第三干扰测量资源上测量获得的；

示例性地，终端设备在M个参考信号资源中的每个参考信号资源及其关联的干扰测量资源上进行CSI测量，获得M个单TRP CSI测量假设对应的CSI。
同时，终端设备在N个信道测量资源对中的每个信道测量资源对及其关联的干扰测量资源上进行CSI测量，获得N个NCJT CSI测量假设对应的CSI。
基于上述关于CSI报告的相关描述可知，对应于选项1，终端设备可以从M个单TRP CSI测量假设对应的CSI中选择m个单TRP CSI测量假设对应的CSI，并从N个NCJT CSI测量假设对应的CSI中选择1个NCJT CSI测量假设对应的CSI，获得CSI报告。
对应于上述选项2，终端设备从M个单TRP CSI测量假设对应的CSI中选择1个单TRP CSI测量假设对应的CSI，或者从N个NCJT CSI测量假设对应的CSI中选择1个NCJT CSI测量假设对应的CSI，获得CSI报告。
步骤330：终端设备向网络设备发送CSI报告。
采用上述如图3所示的实施例，解决了在NCJT CSI测量假设下，与参考信号资源集合关联的干扰测量资源集合中配置的干扰测量资源数量如何配置，以及干扰测量资源集合中干扰测量资源如何与用于单TRP CSI测量假设的参考信号资源和用于NCJT CSI测量假设的信道测量资源对如何关联的问题。其中，干扰测量资源集合包含X个干扰测量资源，其中X＝N+K，进而可以实现即使M的取值不同，同一个参考信号资源集合关联的干扰测量资源集合也是相同，可以实现有效减轻配置资源的复杂度以及终端设备的存储负担。
