技术领域
本申请涉及通信领域，更具体地，涉及一种传输信道状态信息的方法和装置。
背景技术
传统方案中，在波束训练的过程中，需要对多个波束中的每个波束进行信道状态的测量，并向网络设备上报信道质量较好的波束的信息。
为了获得每个波束的信道状态，则网络设备需要为每个波束配置用于信道测量的资源，并且还需要配置信道测量对应的干扰资源，其资源开销大且计算复杂度较高。此外，网络设备在配置干扰资源时，由于无法获知终端设备的接收情况，导致网络设备将非干扰波束配置成干扰资源，使得终端设备上报的信道状态信息不准确。

图1是本申请一个通信系统的示意图。图1中的通信系统可以包括至少一个终端设备(例如终端设备10、终端设备20、终端设备30、终端设备40、终端设备50和终端设备60)和网络设备70。网络设备70用于为终端设备提供通信服务并接入核心网，终端设备可以通过搜索网络设备70发送的同步信号、广播信号等接入网络，从而进行与网络的通信。图1中的终端设备10、终端设备20、终端设备30、终端设备40和终端设备60可以与网络设备70进行上下行传输。例如，网络设备70可以向终端设备10、终端设备20、终端设备30、终端设备40和终端设备60发送下行信号，也可以接收终端设备10、终端设备20、终端设备30、终端设备40和终端设备60发送的上行信号。
此外，终端设备40、终端设备50和终端设备60也可以看作一个通信系统，终端设备60可以向终端设备40和终端设备50发送下行信号，也可以接收终端设备40和终端设备50发送的上行信号。
以图中终端设备60与网络设备70为例进行举例说明。
网络设备70和终端设备60可以使用不同种类的参考信号以完成数据传输，其中，一种参考信号用于信道状态或信道质量的测量，以便于网络设备70根据当前的信道状态或者信道质量调度终端设备60使用的传输资源，通过信道质量较好的信道传输数据。
例如，终端设备60可以从网络设备700接收信道状态信息参考信号(channel state information reference signal，CSI-RS)，并对CSI-RS的信道质量进行测量，得到信道状态信息(channel state information，CSI)。
CSI-RS分为两种类型，一种是零功率(zero power，ZP)CSI-RS，用于干扰测量；另一种是非零功率(non-zero power，NZP)CSI-RS，用于信道状态测量和信道估计。
在5G移动通信系统中，NZP CSI-RS还可以用于干扰测量以及层1(layer 1，L1)的参考信号接收功率(reference signal received power，RSRP)的测量，其中，L1-RSRP用于确定L1的信号干扰噪声比(signal to interference plus noise ratio，SINR)，以便于网络设备70和终端设备60根据波束对应的L1-SINR从多个波束中选出信道质量较好的波束。
CSI可以包括信道质量指示(channel quality indicator，CQI)、预编码矩阵指示(precoding matrix indicator，PMI)、CSI-RS资源指示(CSI-RS resource indicator，CRI)、同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SSB) 资源指示(SSB resource indicator，SSBRI)、层指示(layer indicator，LI)、秩指示(rank indicator，RI)、L1-RSRP和L1-SINR中的至少一种。CSI可由终端设备60通过物理上行控制信道(physical uplink control channel，PUCCH)或物理上行共享信道(physical uplink shared channel，PUSCH)发送给网络设备70。
网络设备70可以通过高层信令(CSI-Report Config)为终端设备60配置至少一种CSI上报配置，并且通过高层信令(CSI-Resource Config)为终端设备60配置至少一种CSI-RS资源配置，其中，CSI上报配置用于指示CSI的上报类型，CSI的上报类型包括周期(periodic)上报、半持续(Semi-Persistent)上报和非周期(aperiodic)上报。CSI-RS资源配置用于指示CSI-RS资源，CSI-RS资源包括周期CSI-RS资源、半持续CSI-RS资源和非周期CSI-RS资源，用于终端设备60上报CSI，其中，周期CSI-RS资源可以用于周期上报或半持续上报或非周期上报，半持续CSI-RS资源可以用于半持续上报或非周期上报，非周期CSI-RS资源只能用于非周期上报。
下面以每个CSI-RS资源配置仅包括一个CSI-RS资源集合为例对CSI-RS资源的配置方法进行说明。
配置方法一
网络设备70可以为终端设备60配置两个资源配置，一个资源配置用于配置信道测量所需的传输资源，如第一参考信号资源集合，为描述方便称该第一参考信号资源集合中的参考信号资源为信道测量资源(channel measurement resource，CMR)。其中，CMR可以是SSB资源，也可以是NZP CSI-RS资源；另一个资源配置用于配置干扰测量所需的传输资源，如第二参考信号资源集合，为描述方便称第二参考信号资源集合中的参考信号资源为干扰测量资源(interference measurement resource，IMR)，其中，IMR可以是CSI干扰测量(CSI interference measurement，CSI-IM)资源，也可以是NZP CSI-RS资源。
配置方法二
网络设备70可以为终端设备60配置三个资源配置，其中，第一个资源配置用于配置CMR，CMR可以是SSB资源，也可以是NZP CSI-RS资源；第二个资源配置和第三个资源配置用于配置IMR，其中，第二个资源配置用于配置CSI-IM资源，第三个资源配置用于配置NZP CSI-RS资源。可选地，该CSI-IM资源可以用于测量小区间的干扰，该NZP CSI-RS资源可以用于测量一个小区内的多用户(multi-user，MU)干扰或者NCJT时多个协作集(即TRP)之间的干扰，或该用户内多个波束间/传输流/传输层之间的干扰。
终端设备60测量上述资源上的参考信号获得信道状态信息。
配置方法三
网络设备70可以为终端设备60配置两个资源配置，两个资源配置均用于配置信道测量所需的传输资源，如第一参考信号资源集合和第二参考信号资源集合，终端设备60测量第一参考信号资源集合中的至少一个参考信号和第二参考信号资源集合中的至少一个参考信号得到两个信道状态信息。其中，第一参考信号资源集合中的CMR上承载的参考信号作为非干扰信号，第二参考信号资源集合中的CMR上承载的参考信号作为干扰信号，该情况下测得一个信道状态信息；第一参考信号资源集合中的该CMR上承载的参考信号作为干扰信号，第二参考信号资源集合中的该CMR上承载的参考信号作为非干扰信号，该情况下测得另一个信道状态信息。
对于波束训练流程，需要从多个波束中选出较优的几个波束，因此CMR资源需要大于一个。而对于每一个CMR资源都需要有对应的IMR资源，若终端设备根据网络设备上述不同的配置方法，进行多个波束的通信质量的测量，并向网络设备上报波束的信道状态信息，则资源开销巨大且测量过程较复杂。由于网络设备对每一个作为信号的资源可能会配置多个对它产生干扰的资源。但是网络设备在配置干扰的资源时，无法获知终端设备是否可以同时接收到配置的作为信号的资源和作为干扰的资源。若终端设备无法同时接收到的作为信号的资源和作为干扰的资源，则导致测量信道状态信息不准确(如测量的干扰过大，信道质量过小)。
有鉴于此，本申请实施例提出了一种传输信道状态信息的方法，在测量信道状态信息的过程中，终端设备能够确定同时接收到的作为信号的参考信号和作为干扰的参考信号，终端设备向网络设备上报信道状态信息时，可以上报作为信号的参考信号的资源索引、作为干扰的参考信号的资源索引以及测量的信道质量信息。即在本申请的实施例中，终端设备根据网络设备的资源配置可以选择作为干扰的资源，不需要根据网络设备的配置进行信道质量的测量，避免测量无法同时接收到的作为信号和干扰的资源之间的信道质量信息，以推荐数据传输采用较优的传输方式，使得网络设备获得准确的信道状态信息。
需要说明的是，终端设备根据多个参考信号向网络设备上报的一个或多个信道状态信息或波束信息(如包括资源索引及其对应的信道质量信息)，可以是终端设备选择上报的，也可以是根据网络设备的指示原则上报的，或者是按照协议预定义的规则上报的。
例如，终端设备可以上报信道质量较好的波束/信道状态信息，或者，终端设备可以上报信道质量较差的波束信息/信道状态信息。本申请对此不作限定。
下面将结合具体的例子详细描述本申请的实施例。需要说明的是，这只是为了帮助本领域技术人员更好地理解本申请实施例，而非限制本申请实施例的范围。
应理解，在本申请的各实施例中，“第一”、“第二”、“第三”、“第四”等仅是为了指代不同的对象，并不表示对指代的对象有其它限定。
方便理解本申请，下面介绍与本申请相关的术语：
1、波束(beam)：
波束是一种通信资源。波束可以是宽波束，或者窄波束，或者其他类型波束。形成波束的技术可以是波束赋形技术或者其他技术手段。波束赋形技术可以具体为数字波束赋形技术，模拟波束赋形技术，混合数字/模拟波束赋形技术。不同的波束可以认为是不同的资源。通过不同的波束可以发送相同的信息或者不同的信息。可选的，可以将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口，用于传输数据信道，控制信道和探测信号等，例如，发射波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。可以理解的是，形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。
波束可以分为网络设备的发送波束和接收波束，与终端设备的发送波束和接收波束。网络设备的发送波束用于描述网络设备发送侧波束赋形信息，基站接收波束用于描述网络设备接收侧波束赋形信息，终端设备的发送波束用于描述终端设备发送侧波束赋形信息，终端接收波束用于描述终端设备接收侧波束赋形信息。也即波束用于描述波束赋形信息。
波束可以对应时间资源和或空间资源和或频域资源。
可选地，波束还可以与参考信号资源(例如，波束赋形的参考信号资源)，或者波束赋形信息对应。
可选地，波束还可以与网络设备的参考信号资源关联的信息对应，其中参考信号可以为CSI-RS，SSB，DMRS,相位跟踪信号(phase tracking reference signal，PTRS),跟踪信号(tracking reference signal,TRS)等，参考信号资源关联的信息可以是参考信号资源标识，或者QCL信息(特别是type D类型的QCL)等。其中，参考信号资源标识对应了之前基于该参考信号资源测量时建立的一个收发波束对，通过该参考信号资源索引，终端可推断波束信息。
可选地，波束还可以与空域滤波器(spatial filter，spatial domain filter),空域传输滤波器(spatial domain transmission filter)对应。
2、同位置假设(quasi-collocation,QCL)信息
准共站/准共址QCL假设信息也可以称为同位置假设信息。QCL信息用于辅助描述终端设备接收侧波束赋形信息以及接收流程。
QCL信息用于指示两种参考信号之间的QCL关系，其中目标参考信号一般是可以是解调参考信号(demodulation reference signal，DMRS)，信道状态信息参考信号(channel state information reference signal，CSI-RS)等，而被引用的参考信号或者源参考信号一般可以是信道状态信息参考信号(channel state information reference signal，CSI-RS)、追踪参考信号(tracking reference signal，TRS)、同步信号广播信道块(synchronous signal/PBCH block，SSB)等。应理解满足QCL关系的两个参考信号或信道的空间特性参数是相同的，从而，基于该源参考信号资源索引可推断出目标参考信号的空间特性参数。其中，空间特性参数包括以下参数中的一种或多种：
入射角(angle of arrival，AoA)、主(Dominant)入射角AoA、平均入射角、入射角的功率角度谱(power angular spectrum，PAS)、出射角(angle of departure，AoD)、主出射角、平均出射角、出射角的功率角度谱、终端发送波束成型、终端接收波束成型、空间信道相关性、基站发送波束成型、基站接收波束成型、平均信道增益、平均信道时延(average delay)、时延扩展(delay spread)、多普勒扩展(Doppler spread)、多普勒频移(Doppler shift)、空间接收参数(spatial Rx parameters)等。
这些空间特性参数描述了源参考信号与目标参考信号的天线端口间的空间信道特性，有助于终端设备根据该QCL信息完成接收侧波束赋形或接收侧处理过程。应理解，终端可以根据QCL信息指示的源参考信号的接收波束信息，接收目标参考信号。
其中，为了节省网络设备侧对终端设备侧的QCL信息指示开销，作为一种可选的实施方式，网络设备侧可以指示PDCCH或PDSCH的解调参考信号与终端设备之前上报的多个参考信号资源中的一个或多个是满足QCL关系的，如，该参考信号可以是信道状态信息参考信号(hannel tate nformation eference ignal，CSI-RS)。这里，每一个上报的CSI-RS资源索引对应了一个之前基于该CSI-RS资源测量时建立的一个收发波束对。应理解满足QCL关系的两个参考信号或信道的接收波束信息是相同的，从而基于该参考信号资源索引UE可推断出接收PDCCH或PDSCH的接收波束信息。
现有标准中定义了四种类型的QCL，基站可以同时给UE配置一个或多种类型的 QCL，如QCL type A+D，C+D：
QCL types A:Doppler shift,Doppler spread,average delay,delay spread；
QCL types B:Doppler shift,Doppler spread；
QCL types C:average delay,Doppler shift；
QCL types D:Spatial Rx parameter。
可选地，本申请实施例中的QCL的关系主要可以指QCL types D类型。
应理解满足空间相关性信息的两个参考信号或信道的空间特性参数是相同的，从而基于该源参考信号资源索引可推断出目标参考信号的空间特性参数。其中，空间特性参数包括以下参数中的一种或多种：
入射角(angle of arrival，AoA)、主(Dominant)入射角AoA、平均入射角、入射角的功率角度谱(power angular spectrum，PAS)、出射角(angle of departure，AoD)、主出射角、平均出射角、出射角的功率角度谱、终端发送波束成型、终端接收波束成型、空间信道相关性、基站发送波束成型、基站接收波束成型、平均信道增益、平均信道时延(average delay)、时延扩展(delay spread)、多普勒扩展(Doppler spread)、多普勒频移(Doppler shift)、空间接收参数(spatial Rx parameters)等。
这些空间特性参数描述了源参考信号与目标参考信号的天线端口间的空间信道特性，有助于终端设备根据该空间相关信息完成发射侧波束赋形或发射处理过程。应理解，终端可以根据空间相关信息指示的源参考信号的发射波束信息，发射目标参考信号。
图2是根据本申请一实施例的传输信道状态信息的方法的示意性流程图。其中，图2的方法可以应用于图1的网络架构。图2的方法包括：
210、接收N个参考信号组，N为大于或等于2的整数。
在本申请的实施例中，终端设备根据网络设备配置的N个参考信号的资源集合，可以接收到N个参考信号组。其中，终端设备可以在网络设备配置的一个参考信号的资源集合处接收一组参考信号，即终端设备接收网络设备配置的N个参考信号的资源集合，在N个参考信号资源集合终端设备可以接收N个参考信号组。
示例性地，网络设备配置了N个参考信号资源集合，其中，包括至少一个资源集合用于信道测量。即终端设备在N个资源集合处接收N个参考信号组，该N个参考信号组中可以包括至少一个用于信道测量的参考信号组。
示例性地，网络设备配置了N个参考信号资源集合，其中，N个资源集合均为用于信道测量的资源配置。即终端设备接收N个参考信号组，该N个参考信号组可以均用于信道测量的参考信号组。
示例性地，网络设备配置了N个参考信号资源集合，其中，包括至少一个资源集合用于信道(或信号)测量和至少一个资源集合用于干扰测量。即终端设备接收N个参考信号组，该N个参考信号组中包括至少一个用于信道测量的参考信号组和至少一个用于干扰测量的参考信号组。
在一种可能的实现方式中，网络设备配置了N个参考信号资源集合中包括至少一个资源集合用于信道(或信号)测量和至少一个资源集合用于干扰测量，用于信道测量的参考信号资源集合与用于干扰测量的参考信号集合可以属于不同的资源配置。
例如，N个参考信号的资源配置中包括第一资源集合中的参考信号资源为CMR，第 二资源集合中的参考信号资源为IMR，CMR可以为NZP CSI-RS或SSB，IMR可以为CSI-IM或NZP CSI-RS。即第一资源集合和第二资源集合可以是不同的资源配置。
应理解，在本申请的实施例中，终端设备根据网络设备配置的N个参考信号的资源集合可以接收到N个参考信号组，不同的资源集合可以是作为信号的资源或者可以是作为干扰的资源。
220、发送信道状态信息，所述信道状态信息包括第一资源索引、第二资源索引和第一信道质量信息，其中，所述第一资源索引为第一参考信号的资源索引，所述第二资源索引为第二参考信号的资源索引，所述第一参考信号和所述第二参考信号为所述N个参考信号组中不同组的参考信号，所述第一信道质量信息是以所述第一参考信号为信号所述第二参考信号为干扰获得的。
在本申请的实施例中，终端设备根据网络设备配置的N个参考信号资源集合接收N个参考信号组，从N个参考信号组中选择作为信号和作为干扰的信号，测量信道质量信息并向网络设备进行上报。
应理解，在本申请的实施例中，第二资源索引可以包括一个或多个第二参考信号的资源索引，作为干扰项的参考信号称为第二参考信号。
还应理解，可选地，第一资源索引的个数和第二资源索引的个数可以是网络设备配置的，或者，可以是协议预定义的，或者可以是终端设备上报的。
作为另一种可选地实施方式，第一资源索引与第二资源索引的个数和可以是基站配置的，可以是协议预定义的，还可以是终端设备上报的，其中，第一资源索引的个数可以是基站配置的，协议预定义的，或终端设备上报的。
可选地，第一资源索引和第二资源索引对应的参考信号是终端设备同时接收和或网络设备同时发送的参考信号。
应理解，本申请实施例中，同时是指，在同一个时刻接收，或者重叠的时刻接收，或者在同一个时间单元接收，或者在至少一个重叠的时间单元接收，M个参考信号至少在一个时间单元重叠。所述时间单元可以是LTE或者5G NR系统中定义的一个或多个无线帧，一个或多个子帧，一个或多个时隙，一个或多个微时隙(mini slot)，一个或多个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以是多个帧或子帧构成的时间窗口，例如，系统信息(system information，SI)窗口。下述实施例以同时接收的参考信号为在一个或多个OFDM符号上接收到的参考信号为例进行说明，本申请对此不进行限定。
示例性地，上报的信道状态信息中可以包括一个第一资源索引、一个第二资源索引以及第一信道质量信息；或者，上报的信道状态信息中可以包括一个第一资源索引、两个第二资源索引以及第一信道质量信息。其中，第一资源索引可以是作为信号的第一参考信号的资源索引，第二索引可以是作为干扰的第二参考信号的资源索引。本申请不对第二资源索引的数量作任何限定。
需要说明的是，第一信道质量信息可以是SINR(如L1-SINR)、CQI、RSRQ、SNR或者其它可以指示信道状态/质量的信息。
在一种可能的实现方式中，终端设备可以接收网络设备发送的第一配置信息，第一配置信息可以指示N个资源集合均为CMR，即指示N个资源集合均为用于信道测量的资源 集合。也就是说，第一配置信息可以指示终端设备接收的N个参考信号组为用于信道测量的参考信号组。
下面以网络设备配置两个资源集合进行举例说明，应理解，网络设备可以向终端设备配置N个资源集合，N为大于2的整数。
在一个示例中，如图3所示，网络设备配置两个参考信号资源集合，包括资源集合1和资源集合2，其中，资源集合1和资源集合2均为用于信道测量的资源集合，资源集合1和资源集合2可以属于不同的资源配置。
例如，资源集合1可以为NZP CSI-RS资源，资源集合2可以为SSB资源。或者，资源集合1可以为SSB资源，资源集合2可以为NZP CSI-RS资源。即网络设备配置的两个参考信号的资源集合可以属于不同的资源配置。
在一个示例中，如图4所示，网络设备配置两个参考信号资源集合，包括资源集合1和资源集合2，其中，资源集合1和资源集合2均为用于信道测量的资源集合，资源集合1和资源集合2可以属于相同的资源配置。
例如，资源集合1和资源集合2可以均为NZP CSI-RS资源；或者，资源集合1和资源集合2可以均为SSB资源。即网络设备配置的两个参考信号的资源集合可以属于相同的资源配置。
也就是说，终端设备可以接收网络设备发送的第一配置信息，第一配置信息可以指示N个资源集合均为CMR，例如，第一配置信息可以指示如图3或图4所示的两个资源集合。
例如，终端设备可以接收网络设备发送的第一配置信息，第一配置信息指示N个资源集合均为用于信道测量的资源，即终端设备接收N个均用于信道测量的参考信号组。终端设备从N个参考信号组中确定一个参考信号组，从一个参考信号组中确定第一参考信号，根据该第一参考信号终端设备可以从N-1个参考信号组中确定一个或者多个作为干扰的第二参考信号。将第一参考信号作为信号项，一个或多个第二参考信号作为干扰项进行信道质量信息的测量。
可选地，终端设备可以根据第一参考信号从N-1个参考信号组中确定可以与第一参考信号同时接收的一个或多个第二参考信号，其中，N-1个参考信号组不包括第一参考信号所在的参考信号组。
在一个可能的实现方式中，当第一配置信息指示第二参考信号所在的参考信号资源集合为用于信道测量的参考信号资源集合时，终端设备可以上报该第二信道质量信息。
也就是说，在网络设备配置的N个资源集合均为CMR时，即终端设备接收的N个参考信号组均为用于信道测量的参考信号组，终端设备还向网络设备发送第二信道质量信息，第二信道质量信息是以第二参考信号作为信号项，第一参考信号作为第二参考信号的干扰项进行信道质量的测量。
网络设备可以向终端设备配置N个资源集合，N为大于或等于2的正整数。以网络设备向终端设备配置两个资源集合为例进行举例说明，其中，网络设备可以配置第一资源集合为用于信道测量的资源集合。
可选地，当网络设备向终端设备发送的资源配置信息指示第二资源集合用于信道测量时，终端设备可以上报第二信道质量信息，第二信道质量信息是以第二参考信号作为信号 项，第一参考信号作为第二参考信号的干扰项确定的。
可选地，当网络设备向终端设备发送的资源配置信息指示第二资源集合用于干扰测量时，终端设备可以不上报第二信道质量信息。
示例性地，终端设备接收网络设备配置的N个资源集合，即接收N个参考信号组。在N个RS set中终端设备可以选出A个RS，其中，A小于或等于N，该A个RS分别来自不同的RS set,也即每个RS set最多选择一个RS。UE以A个RS中的一个RS为信号项，A个RS中的其他RS为干扰项测量信道质量信息。
例如，终端设备接收两个用于信道质量信息测量的RS set1，RS set 2，其中，RS set1中包括L1个参考信号，RS set 2中包括L2个参考信号。L1可以等于L2，或者L1也可以不等于L2。终端设备可以从RS set1中以第一个参考信号为信号项，终端设备可以再从RS set 2中选择参考信号RS X1作为干扰项，计算得到信道质量信息，例如可以计算得到L1-SINR1。
需要说明的是，终端设备在RS set2中可以选择与作为信号项的参考信号能同时接收的参考信号。UE可以依次轮询RS set1中的每个参考信号计算L1-SINR，共获得L1个L1-SINRa。
可选地，UE还可以以RS set2中的参考信号为信号项，RS set 1中的参考信号为干扰项，共获得L1个或L2个L1-SINRb。
例如，UE可以从L1个参考信号中选择L1-SINRa最大的B个参考信号及测量结果，或UE从L1个参考信号中选择其对应的L1-SINRa与L1-SINRb的平均值或等效值最大的K个参考信号及测量结果上报至网络设备。
也就是说，在RS set1，RS set 2均为用于信道质量信息测量的资源时，UE可以上报第一信道质量信息和第二信道质量信息。第一信道质量信息可以是RS set 1中的参考信号为信号项，RS set 2中的参考信号为干扰项测量的信道质量。第二信道质量信息可以是RS set 2中的参考信号为信号项，RS set 1中的参考信号为干扰项测量的信道质量。
可选地，UE还可以发送第一标识信息和/或第二标识信息，其中，第一标识信息用于指示第一参考信号所在参考信号组的标识，第二标识信息用于指示第二参考信号所在参考信号组的标识。
也就是说，当N个资源集合均为CMR时，UE上报的第一资源索引和第二资源索引可能来自不同的RS set，可选地，UE还可以上报对应的第一资源索引所在的set ID和/或第二资源索引所在的set ID。
在一个可能的实现方式中，终端设备可以接收网络设备发送的第二配置信息，第二配置信息可以指示N个资源集合中M个资源集合为CMR，N-M个资源集合为IMR。即第二配置信息可以指示N个参考信号组中包括M个参考信号组为信道测量参考信号组，N-M个参考信号组为干扰测量参考信号组，其中，N大于或等于2，M小于或等于N，M可以等于1。
以网络设备配置两个资源集合进行举例说明，应理解，网络设备可以向终端设备配置N个资源集合，N为大于2的整数。
可选地，终端设备可以在第一资源集合中选择一个第一参考信号，在第二资源集合中选择一个或多个第二参考信号，向网络设备上报第一参考信号的资源索引、一个或多个第 二参考信号的资源索引以及第一信道质量信息。
可选地，终端设备可以在第一资源集合中选择作为信号项的第一参考信号，在第一资源集合和第二资源集合中选择一个或多个作为干扰项的第二参考信号。更进一步地，可选地，终端设备在第一资源集合中选择的一个或多个作为干扰项的第二参考信号不同于第一参考信号。
在一种可能的实现方式中，终端设备可以在第一资源集合中选择作为干扰项的参考信号用于MU干扰,和/或TRP间干扰,和或多个波束间干扰的测量，可以在第二资源集合中选择作为干扰项的参考信号用于小区间干扰测量。
在一种可能的实现方式中，终端设备可以在第一资源集合中选择作为干扰项的参考信号用于MU干扰，TRP间干扰或者多个波束间干扰的测量，可以在第二资源集合中选择作为干扰项的参考信号用于小区间干扰和MU干扰，或TRP间干扰的干扰测量。也可理解为，在第一资源集合中选择作为干扰项的参考信号测量一部分干扰，在第二资源集合中选择作为干扰项的参考信号测量另一部分干扰，该不同集合内选择的至少两个作为干扰项的参考信号测量的干扰类型可以不相同，或不完全相同。
在一种可能的实现方式中，终端设备可以在第一资源集合中选择作为干扰项的参考信号用于小区间干扰,和/或,MU干扰/协作集干扰/波束间的干扰测量，可以在第二资源集合中选择作为干扰项的参考信号用于小区间干扰或波束间的干扰测量。
应理解，可选地，波束间干扰还可以称为多个传输流间的干扰或者多个传输层间的干扰，可以指网络设备的多个发送波束为同一个终端设备服务时多个发送波束之间的干扰。MU干扰可以指在相同时频资源上配对传输的多个用户之间的干扰(也可以理解为一个网络设备服务一个终端设备时对另一个终端设备产生的干扰)。TRP间干扰指一个协作集内的多个TRP为同一个终端设备服务时的多个TRP之间的干扰(也可以理解为一个TRP服务一个终端设备时,另一个TRP对该终端设备产生的干扰)。
在另一种可能的实现方式中，可选地，终端设备还可以在第三资源集合中选择作为干扰项的第三参考信号，结合上述方法，终端设备可以根据第一参考信号，第二参考信号和第三参考信号确定信道质量信息(如第一信道质量信息)，该第三参考信号的资源索引可以不上报。例如，第三资源集合可以是零功率ZP资源配置。在一个示例中，如图5所示，网络设备配置两个参考信号资源集合，包括资源集合1和资源集合2，其中，资源集合1可以为用于信道测量的资源集合，资源集合2可以为用于干扰测量的资源集合，即M可以等于1。
也就是说，UE可以接收网络设备配置的N个资源集合，N个资源集合中包括至少一个资源集合属于用于信道(或信号)测量的资源配置，该N个资源集合中包括至少一个资源集合属于用于干扰测量的资源配置。应理解，上述图5为N＝2时进行的举例说明。
例如，终端设备可以接收网络设备发送的第二配置信息，第二配置信息指示N个资源集合中M个资源集合为用于信道测量的资源，N-M个资源集合为用于干扰测量的资源。即终端设备接收N个参考信号组中包括M个参考信号组为信道测量参考信号组，N-M个参考信号组为干扰测量参考信号组。终端设备从M个参考信号组中确定一个参考信号组，从一个参考信号组中确定第一参考信号，根据该第一参考信号终端设备可以从N-M个参考信号组中确定一个或者多个作为干扰的第二参考信号。将第一参考信号作为信号项，一 个或多个第二参考信号作为干扰项进行信道质量信息的测量。
在一个示例中，UE可以接收网络设备配置的N个资源集合，即接收N个参考信号组。UE在N个RS set中包括a个CMR RS set和b个IMR RS set，其中，UE以a个RS set中的一个RS为信号项，其他b个RS set中选择一个或多个RS为干扰项计算信道质量信息。
可选地，UE还可以发送第三标识信息，第三标识信息用于指示第二参考信号所在参考信号组的标识。
也就是说，当N个资源集合中包括IMR时，UE上报的第二资源索引可能来自不同的RS set，此时UE还需要上报对应的第二资源索引所在的set ID。
示例性地，网络设备可以配置三个resource set，如分别对应三个TRP，UE可以从中选出NCJT的两个TRP，或三个TRP。UE需要根据不同的传输假设测量得到多个信道质量信息，并将此上报至网络设备，以推荐数据传输时使用的传输方式或服务TRP。
在本申请的实施例中，UE可以向网络设备上报第一资源索引、第二资源索引以及第一信道质量信息。例如，UE可以上报CRI1+IMR1+L1-SINR1，其中，CRI1是用于信道测量资源集合中的参考信号，IMR1是用于干扰测量资源集合中的参考信号。L1-SINR1是根据CRI1上测量得到的信号和IMR1上测量得到的干扰计算获得的。
可选地，根据网络设备不同的资源配置，UE可以上报CRI1+CRI2+L1-SINR1+L1-SINR2，其中，CRI1是第一资源集合中的参考信号，CRI2是第二资源集合中的参考信号。L1-SINR1是根据CRI1上测量得到的信号和CRI2上测量得到的干扰计算获得的。L1-SINR2是根据CRI2上测量得到的信号和CRI1上测量得到的干扰计算获得的。
可选地，UE可以上报CRI1+CRI2+CRI3+L1-SINR1+L1-SINR2+L1-SINR3，其中，L1-SIN1R可以是根据CRI1测得的信号，与CRI2和CRI3测得的干扰获得；L1-SINR2可以是根据CRI2测得的信号，与CRI1和CRI3测得的干扰获得；L1-SINR3可以是根据CRI3测得的信号，与CRI1和CRI2测得的干扰获得。
在一种可能的实现方式中，当网络设备配置group based beam reporting(波束组上报)时，UE可以根据上述方法向网络设备上报第一资源索引、第二资源索引以及信道质量信息。
在一种可能的实现方式中，当网络设备配置non-group based beam reporting(非分组波束报告)上报时，UE可以根据上述方法测量信道质量信息。在向网络设备进行上报时，UE可以不上报作为干扰项参考信号的资源ID，而是将CMR对应的IMR资源测得的干扰的平均值作为计算L1-SINR的干扰项。
例如，可以是L1-SINR1＝L1-RSRP5/average(L1-RSRP1+L1-RSRP2+L1-RSRP3)。
在本申请的实施例中，在测量信道状态信息时终端设备能够确定同时接收到的作为信号的参考信号和作为干扰的参考信号，终端设备向网络设备上报信道状态信息时，可以上报作为信号的参考信号的资源索引、作为干扰的参考信号的资源索引以及测量的信道质量信息。即在本申请的实施例中，终端设备根据网络设备的资源配置可以选择作为干扰的资源，不需要根据网络设备的配置进行信道质量的测量，避免测量无法同时接收到的作为信号和干扰的资源之间的信道质量信息，提高了资源的利用效率。
作为一种可选地实施方式，终端设备上报的信道状态信息可以是一个或多个，如K个， K为大于或等于1的整数。其上报的信道状态信息的个数可以是网络设备配置的，或者协议预定义的，或者终端设备上报的。
在一中可能的实现方式中，该K个信道状态信息可以采用如下比特位的顺序映射编码，其中，该信道状态信息包括第一资源索引、第二资源索引和第一信道质量信息时，例如，可以采用以下方法1和方法2上报信道状态信息。
方式1为：全部第一资源索引->全部第二资源索引->全部第一信道质量。即，先映射全部第一资源索引，再映射全部第二资源索引，最后映射全部第一信道质量。应理解，该全部第一资源索引、全部第二资源索引、全部第一信道质量指K个信道状态信息中的第一资源索引，第二资源索引，第一信道质量。
方式2为：第一资源索引1->第二资源索引1->…->第一资源索引K->第二资源索引K->…->第一信道质量1->…->第一信道质量K。即，先顺序映射每个信道状态信息中的资源索引，再顺序映射每个信道状态信息中的信道质量。
需要说明的是，K个第一资源索引可以是不同的，K个第二资源索引可以是相同的。
可选地，还可以先映射第一个信道状态信息再映射第二个信道状态信息，再按顺序依次映射其他信道状态信息。
例如，方式1如表1所示，方式2如表2所示。

方式3为：全部第一资源索引->全部第二资源索引->全部第一信道质量->全部第二信道质量。即，先编码全部第一资源索引，再编码全部第二资源索引，再编码全部第一信道质量，最后编码全部第二信道质量。
方式4为：第一资源索引1->第二资源索引1->…->第一资源索引K->第二资源索引K->第一信道质量1->第二信道质量1->…->第一信道质量K->第二信道质量K。即，先顺序映射每个信道状态信息中的第一资源索引和第二资源索引，再顺序映射每个信道状态信息中的第一信道质量和第二信道质量。

可选地，还可以先映射完第一个信道状态信息再映射第二个信道状态信息，再按顺序依次映射其他信道状态信息。
可选地，信道质量信息可以采用非差分方式上报或差分方式上报，其中当采用差分方式上报时，有如下几种方法：
差分方法1.一个组内的信道质量之间差分，如对于每个信道状态信息，该信道状态信息中若包括第一信道质量和第二信道质量，该第一信道质量与第二信道质量之间差分上报。如，第二信信道质量以第一信道质量为参考采用差分值上报。即终端设备上报第一信道质量以及第一信道质量与第二信道质量的差分值。可选地，作为参考值的信道质量可以是第一信道质量和第二信道质量中的最大值，或最小值，或平均值等。
差分方法2.相同类型信道质量之间差分，如K个信道状态信息中的，第一信道质量之间采用差分上报，如，以第一信道质量1为参考值，第一信道质量2至K采用差分方式上报。即终端设备上报第一信道质量1以及第一信道质量1至K与第一信道质量1的差分值。对于第二信道质量也有类似的方法。如，以第二信道质量1为参考值，第二信道质量2至K采用差分方式上报。即终端设备上报第二信道质量1以及第二信道质量1至K与第二信道质量1的差分值。可选地，其中，作为参考值的信道质量可以是所有信道质量或相同类型的信道质量中的最大值，或最小值，或平均值等。
差分方法3.所有信道质量之间差分，如K个信道质量信息中包括第一信道质量和第二信道质量。以该信道质量中的一个作为参考值，其他信道质量采用差分方式上报。及上报参考信道质量，及其他信道质量的差分值。可选地，其中，作为参考值的信道质量可以 是所有信道质量或相同类型的信道质量中的最大值，或最小值，或平均值等。
应理解，可选地，差分值指两个量之间的差，或比值。
还应理解，可选地，终端设备采用上述何种方式上报信道状态信息可以是由网络设备指示的，或者终端设备上报的，或者是协议预定义的。
还应理解，上述为终端设备上报信道状态信息的方法，对于网络设备可以根据上述方法解码信道状态信息，其中，解码方式可以预定义的，或者，可以是网络设备配置的，或者，可以是终端设备上报的。
图6是根据本申请一实施例的传输信道状态信息的方法的示意性流程图。其中，图6的方法可以应用于图1的网络架构。图6的方法包括：
310、终端接收X个参考信号，X为正整数。
320、发送所述X个参考信号中Y个参考信号的第三信道质量信息，X、Y为正整数且Y小于或等于X。
需要说明的是，在本申请的实施例中第三信道质量信息可以是RSRP。第三信道质量信息还可以是信号功率/信号能量/信号强度等信息。
在一个示例中，终端设备接收X个参考信号之前，终端设备可以接收第一上报配置信息，第一上报配置信息可以是来自于一个网络设备发送的配置信息，也可以是来自于多个不同网络设备发送的配置信息。第一配置信息可以指示第一资源配置和第一上报量(Report Quantity)，其中，第一资源配置信息可以指示X个参考信号的资源，第一待上报的信道质量信息为第三信道质量信息。
也就是说，终端设备可以接收一个网络设备发送的X个参考信号的资源配置信息，从而接收X个参考信号。或者，多个网络设备向终端设备发送的资源配置信息指示X个参考信号的资源。
例如，上报配置可以包括以下字段：

示例性地，终端设备根据接收到的第一上报配置信息可以确定X个参考信号的资源，接收X个参考信号。根据第一上报配置信息中指示的第一上报量为第三信道质量信息，即第一待上报的信道质量的类型可以为RSRP。终端设备可以测量接收到的X个参考信号的RSRP，确定X个参考信号中RSRP较好的Y个参考信号。终端设备向网络设备发送Y个参考信号的RSRP。
需要说明的是，终端设备根据测量X个参考信号的RSRP确定信道质量较好的Y个参考信号向网络设备进行上报。其中，由于X个参考信号的资源配置可以来自于一个网络设备，也可以是来自于多个网络设备对终端设备进行的配置。因此，上报的Y个参考信号可能为来自于一个网络设备配置的资源，也可能是来自于不同的多个网络设备配置的资源。
可选地，网络设备接收终端设备上报的Y个参考信号的第三信道质量信息，向终端设备发送第二上报配置信息，所述第二上报配置信息指示第二资源配置和第二上报量(quantity)，其中，所述第二资源配置指示L个参考信号的资源和Q个第三参考信号的资源，所述L个参考信号为用于信道测量的参考信号，所述第三参考信号为用于干扰测量的参考信号，所述第二上报量为第四信道质量信息，Q为正整数。

在本申请的实施例中，第二上报配置与第一上报配置满足关联关系，即终端设备可以接收X个参考信号，通过测量X个参考信号的L1-RSRP选出Y个较好的参考信号向网络设备上报，再根据Y个参考信号的L1-RSRP上报P个参考信号的信道质量信息，例如，根据Y个参考信号的L1-RSRP上报P个参考信号的L1-SINR，从而确定出较好的参考信号。通过建立两个上报配置的关联关系可以有效降低资源开销，减少上报开销，降低计算复杂度。
可选地，在本申请的实施例中，第四信道质量信息可以是以下任意一项：信号干扰噪声比SINR、信噪比SNR、信道质量指示CQI、参考信号接收质量RSRQ。

例如，对于波束训练过程中，X＝64，Y＝8，L＝4，P＝2。即根据资源配置终端设备可以接收到64个参考信号，终端设备从这64个参考信号中可以确定其中8个RSRP较好的参考信号。终端设备接收的第二配置信息中可以配置4个参考信号的资源，即测量该4个参考信号的信道质量信息，可以是测量信号干扰噪声比SINR、信噪比SNR、信道质量指示CQI或者参考信号接收质量RSRQ等，根据测量结果终端设备可以向网络设备发送较好的2个参考信号。
可选地，终端设备还需要上报该2个参考信号对应的参考信号的资源索引。
示例性地，第二上报配置与第一上报配置满足第一关联关系，即根据第二上报配置可以索引至第一上报配置，第二上报配置指示的第二上报量可以基于第一上报量获取。也就是说，第一关联关系可以指示根据所述Y个参考信号的第三信道质量信息确定P个参考信号的第四信道质量信息。
可选地，第一关联关系可以是协议预定义的或者网络设备配置的关联关系。

也就是说，终端设备接收第二上报配置信息后，可以选择作为信号项的参考信号和作为干扰项的干扰信号上报第四信道质量信息。
可选地，第二上报配置指示的第二资源配置中的L个参考信号的资源可以是Y个参考信号的子集。如图7所示，第二上报配置指示的CMR资源集合中包括的参考信号的资源为上报的Y个参考信号的资源的子集。

可选地，resource config a1中的参考信号可以是周期的参考信号或者半周期的参考信号(例如，可以是CSI-RS或SSB等)。
可选地，resource config a2中的发送的参考信号是非周期的参考信号(例如，可以是CSI-RS等)。该参考信号主要指用于干扰测量的参考信号，即resource config a2中IMR参考信号可以是非周期的参考信号。
可选地，resource config a2中的全部或部分参考信号可以指示但不发送。
可选地，resource config a2中的用于信道测量的参考信号CMR指示但可以不发送。即接收第二上报配置信息后，可以指示CMR资源集合不需要再发送CMR集合中的参考信号。
可选地，resource config a2可以配置一个或者多个资源集合。在resource config a2配置多个资源集合时，多个资源集合中可以包括至少一个CMR资源集合和至少一个IMR资源集合，或者，多个资源集合中可以全部都是CMR资源集合。
可选地，本申请中的第二资源配置可以仅配置Q个第三参考信号资源。可选地，此时终端设备根据Y个参考信号和该Q个第三参考信号获取第四信道质量信息。
可选地，resource config a2中的用于干扰测量的参考信号IMR可以发送，即终端设备可以接收第二上报配置中指示的用于干扰测量的资源集合中的参考信号。
可选地，第一资源配置指示的X个参考信号的周期小于第二资源指示的Q个参考信号的周期。
通过上述方法可以进一步节省开销，且缩短上报时延。
