背景技术

具体实施方式
下面结合附图和实施例对本申请进行说明。此处所描述的具体实施例仅仅用于解释本申请。为了便于描述，附图中仅示出了与本申请相关的部分。
在新空口(New Radio，NR)版本Release15中，由基站(例如下一代基站(next generation NodeB，gNB)或TRP)控制的时间和频率资源可用于UE上报CSI。CSI可由信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示符(Precoding Matrix Indicator，PMI)、信道状态信息参考信号资源指示(Channel State Information-Referece Signal Resource Indicator，CRI)、同步信号/物理广播信道(Synchronization Signal/Physical Broadcast Channel，SS/PBCH)块资源指示(SS/PBCH Block Resource Indicator，SSBRI)、层指示(Layer Indicator，LI)、秩指示(Rank Indicator，RI)等组成。
图1为一实施例提供的一种TRP和终端通信的示意图。基站侧可以灵活配置CMR资源的个数和测量方式等。如图1所示，TRP可通过波束向UE发送一个或多个CMR资源。此外，TRP还可以给UE配置一个或多个CSI上报反馈设置(CSI-ReportConfig)以及一个或多个CSI资源设置(CSI-ResourceConfig)，一个CSI上报反馈设置最多可链接到三个CSI资源设置。UE根据这些CMR测量CSI并上报。
基站侧可以为UE配置一个或多个信道状态信息参考信号(Channel State Information-Referece Signal，CSI-RS)资源用于有用信道测量，并配置一个或多个信道状态信息干扰测量(Channel State Information Interference Measurement，CSI-IM)资源用于干扰测量，其中CSI-RS资源和CSI-IM资源是一一对应关系。在CSI-RS资源为一个的情况下，UE根据对该CSI-RS资源的测量上报CSI，包括RI、PMI、CQI等；在CSI-RS资源为多个的情况下，通常多个CSI-RS资源经过预编码，每个CSI-RS资源代表一个预编码矩阵，用于CSI-RS的预编码信息可由基站侧确定，例如通过遍历全空间内的离散傅里叶变换(Discrete Fourier Transform，DFT)波束成形矢量确定，或者根据对探测参考信号(Sounding Reference Signal，SRS)的测量进行推算。UE测量多个CSI-RS资源并从中挑选出信道质量最好的一个CSI-RS资源，上报指示该CSI-RS资源的CRI，并根据对该CSI-RS资源的测量反馈RI、PMI、CQI等CSI。如果基站侧为UE设置一个CSI-RS资源用于有用信道测量、一个或多个CSI-RS资源用于干扰测量，则该有用信道的测量关联于所有的干扰测量资源。在CSI-RS干扰测量资源中，每个CSI-RS天线端口对应于干扰的一层，UE在每个CSI-RS干扰测量资源的多个天线端口上测量到的信道矩阵，即为干扰信道矩阵，UE可通过该矩阵计算干扰信道的协方差阵、零空间等，以用于计算和反馈干扰信道下最优的预编码矩阵和CQI。
在本申请实施例中，提供一种信道状态信息上报方法，UE在测量CSI的过程中，根据不同TRP发射的波束所对应的参考信号测量资源之间的配对关系，考虑了参考信号测量资源之间的干扰，从而提高CSI测量和上报的准确性。
图2为一实施例提供的一种信道状态信息上报方法的流程图，如图2所示，本实施例提供的方法包括步骤110和步骤120。
在步骤110中，接收测量资源配置信令，所述测量资源配置信令用于指示M个参考信号测量资源以及参考信号测量资源的配对信息，M＞1。
本实施例中，配对信息用于指示参考信号测量资源之间的配对关系，即指示哪些参考信号测量资源之间存在干扰。例如，配对信息可以是M个参考信号测量资源中存在干扰的资源对的数量、编号和/或在缓存中的排列位置等，UE 据此在测量一个参考信号测量资源的CSI的过程中可以考虑与其配对的另一个参考信号测量资源造成的干扰，提高测量的准确性。此外，配对信息中还可以包含M个参考信号测量资源对应的CSI上报反馈设置或CSI资源设置，以指示UE针对每个参考信号测量资源，在不同的CSI上报反馈设置中上报CSI，或者是将存在干扰的资源对的CSI合并在一个CSI上报反馈设置中上报。
在步骤120中，根据所述配对信息上报所述信道状态信息。
本实施例中，UE在测量一个参考信号测量资源的CSI时可以考虑与其配对的另一个参考信号测量资源造成的干扰，提高测量的准确性。还可以针对每个参考信号测量资源，在不同的CSI上报反馈设置中上报CSI，或者是将存在干扰的资源对的CSI合并在一个CSI上报反馈设置中上报。
在一实施例中，每个参考信号测量资源分别对应于至少一个分组标识。
本实施例中，基站侧可以通过无线资源控制(Radio Resource Control，RRC)信令给每个CMR资源配置至少一个分组标识(GroupID)，用于指示该CMR是否用于配对。对于既可以与其他CMR资源配对、也可以不配对的CMR资源可以配置多个不同的分组标识。
一种示例中，每个参考信号测量资源对应于一个分组标识。例如，TRP1发送的波束记为beam1、beam2、beam3、beam4，对应的CMR资源记为CMR1、CMR2、CMR3、CMR4。TRP2发送的波束记为beam5、beam6、beam7、beam8，对应的CMR资源记为CMR5、CMR6、CMR7、CMR8。其中[beam3，beam5]，[beam4，beam6]构成两组配对的波束对，beam1、beam2、beam7、beam8没有进行波束配对。这种情况下，CSI上报反馈设置中的CMR资源为{CMR3，CMR5，CMR4，CMR6，CMR1，CMR2，CMR7，CMR8}。
表1为一种参考信号测量资源与分组标识的映射表。如表1所示，CMR3和CMR5可以对应于相同的分组标识，GroupID为0；CMR4和CMR6可以对应于相同的分组标识，GroupID为1；CMR1、CMR2、CMR7、CMR8之间不存在配对关系，对应的分组标识分别为2、3、4、5。[CMR3，CMR5]和[CMR4，CMR6]关联的基站是多传输接收点(Multi Transmission Receiving Point，MTRP)，而CMR1、CMR2、CMR7、CMR8关联的基站是单传输接收点(Single Transmission Receiving Point，STRP)。
表1 参考信号测量资源与分组标识的映射表
Figure PCTCN2021140556-appb-000001
Figure PCTCN2021140556-appb-000002
一种示例中，每个参考信号测量资源也可以对应于多个分组标识。例如，一个CMR资源既关联了STRP，又关联了MTRP，则基站侧为该CMR资源配置两个GroupID。例如TRP1的beam3，既可以和TRP2的beam5配对，又可以不配对，则CMR3可对应于两个GroupID。
表2为另一种参考信号测量资源与分组标识的映射表。如表2所示，CMR3可对应于两个GroupID，一个GroupID为0，表示CMR3与CMR5配对，[CMR3，CMR5]关联的是基站是MTRP；另一个GroupID为2，表示CMR3不与其他CMR资源配对，CMR3关联了STRP。
表2 参考信号测量资源与分组标识的映射表
Figure PCTCN2021140556-appb-000003
在一实施例中，具有相同分组标识的参考信号测量资源具有配对关系。
本实施例中，基站侧通过给配对的CMR资源配置相同的分组标识，给不具有配对关系的参考信号测量资源配置一个单独的分组标识，使UE可以准确地获得CMR资源的配对信息，明确存在干扰的CMR资源。
本实施例在为关联STRP的CMR资源以及关联MTRP的CMR资源配置分组标识的过程中，不考虑先后顺序，即分组标识由小到大，可以是先分配给关联MTRP的CMR资源，再分配给关联STRP的CMR资源。
在一实施例中，所述测量资源配置信令包括具有配对关系的资源对的数量N，N≤M/2。
本实施例中，基站侧通过RRC配置一个参数N用于指示具有配对关系的资源对的数量，如果没有需要配对的CMR资源，则N＝0。
例如，TRP1发送的波束记为beam1、beam2、beam3、beam4，对应的CMR资源记为CMR1、CMR2、CMR3、CMR4。TRP2发送的波束记为beam5、beam6、beam7、beam8，对应的CMR资源记为CMR5、CMR6、CMR7、CMR8。其中 [beam3，beam5]，[beam4，beam6]构成两组配对的波束对，beam1、beam2、beam7、beam8没有进行波束配对。这种情况下，CSI上报反馈设置中的CMR资源为{CMR3，CMR5，CMR4，CMR6，CMR1，CMR2，CMR7，CMR8}，N＝2。UE根据N＝2，可以在需要上报CSI的CMR资源中从前往后，依次取4个CMR资源并且按顺序两两配对。
在一些实施例中，在N＝2的情况下，也可以按照从后往前的顺序依次取4个CMR资源并且按顺序两两配对，当然也可以按照其他预定义的顺序以及配对规则，将相应位置的CMR资源配对。
在一实施例中，在设定低频波段，具有配对关系的参考信号测量资源支持关联于单传输接收节点；在设定高频波段，具有配对关系的参考信号测量资源不支持关联于单传输接收节点。
本实施例中，在设定低频波段，具有配对关系的参考信号测量资源支持关联于STRP，即，一个CMR资源既可以与其他CMR资源配对，也可以不配对，例如表2中的CMR3；在设定高频波段，具有配对关系的参考信号测量资源不支持关联于STRP，即，一个CMR资源不能同时关联于MTRP和STRP。
在一实施例中，M个参考信号测量资源中具有配对关系的参考信号测量资源满足预定义的相对顺序关系。
本实施例中，预定义的相对顺序关系包括：具有配对关系的参考信号测量资源是相邻的，且具有配对关系的参考信号测量资源位于参考信号测量资源配置中的前端、后端、中间或者两边；或者，具有配对关系的参考信号测量资源位于未配对的参考信号测量资源的之前、之后、中间或者两侧；相应的，具有配对关系的CMR资源在缓存器中的位置，是处于缓存器的左侧、右侧、中间或者两侧，或者是位于未配对的CMR资源的左侧、右侧、中间或者两侧。
在一实施例中，预定义的相对顺序关系包括：
具有配对关系的参考信号测量资源是相邻的，且位于参考信号测量资源配置中或者M个参考信号测量资源中未配对的参考信号测量资源的前面或者后面或者中间或者两侧。
图3为一实施例提供的一种参考信号测量资源相对顺序的示意图。本实施例中，UE在接收到TRP1和TRP2的波束的情况下，将配对的CMR资源按照从右往左的顺序存储在缓存器的左侧，将未配对CMR资源按照从左往右的顺序存储在缓存器的右侧。如图3所示，阴影区域所示的CMR资源表示已配对的CMR资源。[beam3，beam5]，[beam4，beam6]构成两组配对的波束对，beam1、beam2、beam7、beam8没有进行波束配对，则CMR3、CMR5、CMR4、CMR6 从缓存器的中间向左依次存储；CMR1、CMR2、CMR7、CMR8从缓存器的中间向右依次存储。
在图3的基础上，N＝2，则UE在CMR资源中从前往后依次取前4个CMR并进行两两配对，得到{[CMR6，CMR4]，[CMR5，CMR3]}关联MTRP，其余的CMR资源{CMR1，CMR2，CMR7，CMR8}关联STRP。

在一些实施例中，也可以将配对的CMR资源按照顺序存储在缓存器的右侧，将未配对CMR资源按照顺序存储在缓存器的左侧。
图5为再一实施例提供的一种参考信号测量资源相对顺序的示意图。本实施例中，UE可以将配对的CMR资源对称存储在缓存器的两侧，将未配对CMR资源存储在缓存器的中间。如图5所示，阴影区域所示的CMR资源表示已配对的CMR资源。例如，[beam3，beam5]，[beam4，beam6]构成两组配对的波束对，beam1、beam2、beam7、beam8没有进行波束配对，则CMR3和CMR5存储在缓存器的第一位和最后一位，CMR4、CMR6存储在缓存器的第二位和倒数第二位；CMR1、CMR2、CMR7、CMR8存储在缓存器的中间。
图6为又一实施例提供的一种参考信号测量资源相对顺序的示意图。如图6所示，UE在接收到TRP1和TRP2的波束的情况下，也可以将配对的CMR资源对称存储在缓存器的中间，将未配对CMR资源存储在缓存器的两侧。
图7为又一实施例提供的一种参考信号测量资源相对顺序的示意图。本实施例中，一个CMR资源既关联了STRP，又关联了MTRP，则可将该CMR资源同时存储在缓冲器的左右两侧。如图7所示，阴影区域所示的CMR资源表示已配对的CMR资源，存储在缓存器的左侧，无阴影区域所述的CMR资源存储在缓存器的右侧。CMR3资源既关联了STRP，又关联了MTRP，这种情况下CSI上报反馈设置中的CMR资源为{CMR6，CMR4，CMR5，CMR3，CMR3，CMR1，CMR2，CMR7，CMR8}，CMR3同时存储在缓存器的两侧。在此基础上，UE根据N＝2，可在CMR资源中从前往后，依次取前4个CMR资源两两配对，得到{[CMR6，CMR4]，[CMR5，CMR3]}关联MTRP，其余的CMR资源{CMR3，CMR1，CMR2，CMR7，CMR8}关联STRP，CMR3既关联了STRP，又关联了MTRP。

本实施例中，对于设定低频波段FR1，可能存在参考信号测量资源既关联于STRP又关联于MTRP，UE根据两个TCI测量两个TRP发射的M个参考信号测量资源，并根据M确定CSI以及CRI的比特个数。
在一实施例中，CSI中包含一个CRI，用于指示M个参考信号测量资源中的一个资源，或者一个资源对；该CRI占用至少

个比特。
在一实施例中，N的数值可以小于实际具有配对关系的资源对的数量，在这种情况下，部分存在干扰的CMR资源会被UE忽略。例如，在[beam3，beam5]， [beam4，beam6]构成两组配对的波束对的情况下，将N配置为1，则在TRP1的CSI上报反馈设置中得到如下CMR资源{CMR1，CMR2，[CMR3，CMR5]，CMR4}，此时得到TRP2对TRP1的干扰资源为CMR5。由于N＝1，TRP2对TRP1的干扰资源CMR6被忽略。同理，在TRP2的CSI上报反馈设置中得到如下CMR资源{[CMR5，CMR3]，CMR6，CMR7，CMR8}，得到TRP1对TRP2的干扰资源为CMR3，由于N＝1，TRP2对TRP1的干扰资源CMR4被忽略。
在一实施例中，具有配对关系的参考信号测量资源对应于相同的CSI上报反馈设置，或者相同的参考信号测量资源配置，或者相同的参考信号测量资源集合。
本实施例中，UE将具有配对关系的参考信号测量资源存储在同一个CSI上报反馈设置中进行上报。
在一实施例中，具有配对关系的参考信号测量资源对应于不同的CSI上报反馈设置，或者不同的参考信号测量资源设置，或者不同的参考信号测量资源集合。
本实施例中，UE将具有配对关系的参考信号测量资源存储在两个CSI上报反馈设置中进行上报。在基站侧，通过将一个TRP的CSI上报反馈设置的CMR资源配置另一个TRP的CMR资源的ID，以显性指示两个CMR资源存在干扰。此外，还可以再配置参数N用于表示CSI上报反馈设置中CMR资源的配对的个数，如果没有配对的CMR资源，则N＝0。
例如，TRP1发送的波束为beam1、beam2、beam3、beam4，对应的CMR资源为CMR1、CMR2、CMR3、CMR4；TRP2发送的波束为beam5、beam6、beam7、beam8，对应的CMR资源为CMR5、CMR6、CMR7、CMR8，其中[beam3，beam5]，[beam4，beam6]是两组配对的波束对。beam1、beam2、beam7、beam8没有进行波束配对。在TRP1的CSI上报反馈设置中，N＝2，并且将CMR5、CMR6分别与TRP1的CMR3、CMR4建立关联关系。
在一实施例中，在每个CSI上报反馈设置中，或者在每个参考信号测量资源设置中，或者在每个参考信号测量资源集合中，满足：前N个参考信号测量资源一一对应且具有配对关系；或者，后N个参考信号测量资源一一对应且具有配对关系。
图8为一实施例提供的一种信道测量参考信号资源配置的示意图。如图8所示，TRP1和TRP2中CMR资源的配对关系，可以在报告设置级别(Report Setting Level)上建立，也可以在资源设置级别(Resource Setting Level)上建立，也可以在资源集合级别(Resource Set Level)上建立。
在报告设置级别上建立，即把report setting2上指示CMR5和CMR6的ID，分别配在report setting1上指示CMR3和CMR4的ID下面，从而建立[CMR3,CMR5]和[CMR4,CMR6]的关联关系。
在资源设置级别上建立，即把resource setting2上指示CMR5和CMR6的ID，分别配在resource setting1上指示CMR3和CMR4的下面，从而建立[CMR3,CMR5]和[CMR4,CMR6]的关联关系。
在资源集合级别上建立，即把resource set2上指示CMR5和CMR6的ID，分别配在resource set1上指示CMR3和CMR4的下面，从而建立[CMR3,CMR5]和[CMR4,CMR6]的关联关系。
在此基础上，在TRP1的CSI上报反馈设置中可以得到如下CMR资源{CMR1，CMR2，[CMR3，CMR5]，[CMR4，CMR6]}。从而得到TRP2对TRP1的干扰资源为CMR5和CMR6。
类似地，在TRP2的CSI上报反馈设置中可以得到如下CMR资源{[CMR5，CMR3]，[CMR6，CMR4]，CMR7，CMR8}。从而得到TRP1对TRP2的干扰资源为CMR3和CMR4。
在一实施例中，具有配对关系的两个参考信号测量资源中，第一个参考信号测量资源用于信道测量，第二个参考信号测量资源是非零功率的第二类信道状态信息参考信号，用于干扰测量。
本实施例中，UE将关联于MTRP的两组CMR分别放在两个CSI上报反馈设置中进行上报。在基站侧，通过在两个CSI上报反馈设置中分别额外增加第二类信道状态信息参考信号的配置，用于隐性指示另一个CMR属于干扰。其中，第一个非零功率的参考信号测量资源是传统的CSI-RS，用于测量UE所处小区内其他用户的干扰；增加的第二类非零功率的参考信号测量资源是第二类信道状态信息参考信号CSI-RS*，用于测量来自另一个TRP的干扰。
图9为一实施例提供的一种增加第二类非零功率的参考信号测量资源配置的示意图。如图9所示，在第一种CSI上报反馈设置中包括CMR资源、CSI-RS资源和CSI-IM资源，分别用于信道测量、小区内的干扰测量以及小区间的干扰测量。在MTRP的场景下，在存在波束配对的情况下，还存在端口(Port)间的干扰测量，即一个TRP的CMR资源会对另一个TRP的信道测量造成干扰。在第二种CSI上报反馈设置中，额外配置CSI-RS*用于测量port间的干扰。假设TRP1发送的波束为beam1、beam2、beam3、beam4，对应的CMR资源为CMR1、CMR2、CMR3、CMR4。TRP2发送的波束为beam5、beam6、beam7、beam8，对应的CMR资源为CMR5、CMR6、CMR7、CMR8。其中[beam3，beam5]，[beam4， beam6]是两组配对的波束对。beam1、beam2、beam7、beam8没有进行波束配对。在TRP1的CSI上报反馈设置中，额外配置的CSI-RS*可供UE测量到TRP2中CMR5和CMR6对TRP1中CMR3和CMR4造成的port间干扰。同理，在TRP2的CSI上报反馈设置中，额外配置的CSI-RS*可供UE测量到TRP1中CMR3和CMR4对TRP2中CMR5和CMR6造成的port间干扰。
在一实施例中，M个参考信号测量资源共占用信道状态信息处理单元(CSI Processing Unit，CPU)的个数为pN+qM或pN+q(M-2N)，其中p为每个具有配对关系的资源对占用的CPU的个数；q为每个参考信号测量资源占用的CPU的个数。
本实施例中，对于低频波段FR1，存在准共址(Quasi-Colocation，QCL)typeD，即存在既可以进行配对，也可以不配对的参考信号测量资源，参考信号测量资源共占用CPU的个数为pN+qM；对于高频波段FR2，不存在QCL-typeD，即不存在既可以进行配对，也可以不配对的参考信号测量资源，参考信号测量资源共占用CPU的个数为pN+q(M-2N)，其中p为每组已配对参考信号测量资源对占用的CPU的个数，q为未配对参考信号测量资源占用的CPU的个数，N为具有配对关系的资源对的数量，M为全部参考信号测量资源数量。
在本申请实施例中，还提供一种资源配置方法，基站侧对参考信号测量资源进行配对，并通过测量资源配置信令向UE指示参考信号测量资源的配对信息，使UE在测量CSI的过程中，根据不同TRP发射的波束所对应的参考信号测量资源之间的配对关系，考虑了参考信号测量资源之间的干扰，从而提高CSI测量和上报的准确性。
