具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。

为方便理解本申请，下面介绍与本申请相关的术语：
波束(beam)：
波束是一种通信资源，不同的波束可以认为是不同的通信资源。不同的波束可以发送相同的信息，也可以发送不同的信息。波束可以对应时域资源、空间资源和频域资源中的至少一项。
可选地，具有相同或者类型的通信特征的多个波束可以视为一个波束，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，发送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。
具体地，波束可以是宽波束，也可以是窄波束，还可以是其他类型的波束。形成波束的技术可以是波束成型技术也可以是其他技术手段，本申请对此不进行限定。其中，波束成型技术(Beamforming)可以是通过在空间上朝向特定的方向来实现更高的天线阵列增益。此外，波束可以分为网络设备的发送波束和接收波束，与终端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接收侧波束赋形信息，网络设备的接收波束用于描述网络设备接收侧波束赋形信息。终端的发送波束用于描述终端发送侧波束赋形信息，终端的接收波束用于描述接收侧波束赋形信息。
更具体地，波束成型技术包括数字波束成型技术、模拟波束成型技术和混合数字模拟波束成型技术。其中，模拟波束成型技术可以通过射频实现，例如，一个射频链路(RF chain)通过移相器来调整相位，从而控制模拟波束方向的改变。因此，一个RF chain在同一时刻只能打出一个模拟波束。此外，基于模拟波束的通信，需要发送端和接收端的波束对齐，否则无法正常传输信号。
应理解，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。
还应理解，波束还可以通过空间滤波器(spatial filter)或空间传输滤波器(spatial domain transmission filter)体现，换句话说，波束也可以称为“空间滤波器”，其中发射波束称为“空间发射滤波器”，接收波束称为“空间接收滤波器”或“下行空间滤波器”。网络设备的接收波束或终端设备的发送波束还可以称为“上行空间滤波器”，网络设备的发送波束或终端设备的接收波束还可以称为“下行空间滤波器”。图2示出了波束训练的示意图。最优的N个波束对(Beam pair link，BPL)(一个BPL包括一个网络设备的发射波束和一个终端的接收波束，或者，一个BPL包括一个终端的发射波束和一个网络设备的接收波束)的选择。用于终端基于网络设备的波束扫描实现对网络设备的发射波束和/或终端的接收波束的选择，以及，网络设备基于终端的波束扫描实现对终端的发射波束和/或网络设备的接收波束的选择。
具体地，发射波束可以为基站发射波束，也可以为终端发射波束。当该发射波束为基站发射波束时，基站通过不同的发射波束向UE发送参考信号，UE通过同一个接收波束来接收基站通过不同的发射波束发送的参考信号，并基于接收信号确定基站的最优发射波束，然后将基站的最优发射波束反馈给基站，以便于基站对发射波束进行更新。当该发射波束为终端发射波束时，UE通过不同的发射波束向基站发送参考信号，基站通过同一个接收波束来接收UE通过不同的发射波束发送的参考信号，并基于接收信号确定UE的最优发射波束，然后将UE的最优发射波束反馈给UE，以便于UE对发射波束进行更新。其中，上述通过不同的发射波束发送参考信号的过程可以称为波束扫描，基于接收信号确定最优发射波束的过程可以称为波束匹配。
接收波束可以为基站接收波束，也可以为终端接收波束。当该接收波束为基站接收波束时，UE通过同一个发射波束向基站发送参考信号，基站采用不同的接收波束接收UE发送的参考信号，然后基于接收信号确定基站的最优接收波束，以对基站的接收波束进行更新。当该接收波束为UE的接收波束时，基站通过同一个发射波束向UE发送参考信号，UE采用不同的接收波束接收基站发送的参考信号，然后基于接收信号确定UE的最优接收波束，以对UE的接收波束进行更新。
需要说明的是，对于下行波束的训练，网络设备会配置参考信号资源集合的类型用于波束训练，当为参考信号资源集合配置的重复参数为“on”时，终端设备假设该参考信号资源集合中的参考信号使用相同的下行空间滤波器传输，也即使用相同的发送波束传输；此时，一般情况下，终端设备会使用不同的接收波束接收上述参考信号资源集合中的参考信号，训练出终端设备最好的接收波束，可选地，终端设备可以上报UE测量的最好的N个参考信号的信道质量。当为参考信号资源集合配置的重复参数为“off”时，终端设备不会假设该参考信号资源集合中的参考信号使用相同的下行空间滤波器传输，也即不假设网络设备使用相同的发送波束传输参考信号，此时终端设备通过测量该集合中参考信号的信道 质量在该资源集合中选出最好的N个波束反馈给网络设备，一般情况下，此时，终端设备在此过程中使用相同的接收波束。
传统方案中，在波束训练的过程中，终端针对网络设备配置的多个波束进行通信质量的测量，并向网络设备上报通信质量较好的波束的信息。网络设备也可以配置终端上报的最大波束数目，终端可以上报小于或等于该最大波束数目的波束的信息。这样网络设备可以采用终端上报的波束进行收发数据，但是传统方案中通信效率较低。
图3示出了本申请实施例的传输信道状态信息的方法的示意性流程图。
301，终端接收N个参考信号组，该N个参考信号组中的每个参考信号组包括至少两个参考信号，该每个参考信号组中的至少两个参考信号为同时接收的参考信号，其中，N≥1，且N为整数。相应地，网络设备发送该N个参考信号组。
具体地，本申请实施例中的不同参考信号的发送波束不同。终端接收N个参考信号组，其中，N>1或N＝1，每个参考信号组包括终端能够同时接收到的至少两个参考信号。其中，每个参考信号组包括的参考信号的数目可以相同，也可以不同，本申请对此不进行限定。下述实施例可以以每个参考信号组包括相同数目的参考信号为例进行说明，但本申请并不限于此。例如，每个参考信号组包括M个参考信号，M>1，且M为整数。
需要说明的是，该N个参考信号组中的每个参考信号组的M个参考信号可以来自同一个传输接收点(transmission and Reception Point，TRP)，也可以分别来自不同的TRP，也可以部分来自同一个TRP，本申请对此不进行限定。
还需要说明的是，终端能够同时接收的参考信号，可以是网络设备同时发送的，也可以不是网络设备同时发送的。例如，不同的TRP与终端的距离不同，则不同时刻从不同TRP发送后到达终端的时刻可以是相同的，即终端能够同时接收到在不同时刻发送的参考信号。
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。
应理解，本申请实施例中，终端设备上报同时接收的参考信号的信道状态信息可以理解为，网络设备给终端设备配置的参数(groupBasedBeamReporting)为“使能”状态时，终端设备上报的参考信号的信道状态信息。一般来说，网络设备会在给终端设备发送的上报配置信息中指示其上报类型，该上报配置信息中的参数groupBasedBeamReporting为“使能”状态时，终端设备才会上报其可以同时接收的参考信号的信道状态信息；否则对终端设备在一个时刻上报的多个参考信号不做限定(可以是同时接收的，也可以不是同时接收的)。
可选地，在接收该N个参考信号组之前，终端还可以接收网络设备发送的配置信息，该配置信息用于指示该N个参考信号组，以及该N个参考信号组中每个参考信号组包括 的参考信号。
具体地，网络设备可以直接通过配置信息指示该N个参考信号组以及该N个参考信号组中每个参考信号组包括的参考信号，也可以通过其他方式间接指示该N个参考信号组以及该N个参考信号组中每个参考信号组包括的参考信号，本申请对此不进行限定。
需要说明的是，该配置信息可以是无线资源控制协议(Radio Resource Control，RRC)，媒体访问控制(media access control，MAC)-控制元素(control element，CE)，下行控制信息(downlink control information，DCI)中的至少一种。
可选地，该配置信息间接指示该N个参考信号组，以及该N个参考信号组中每个参考信号组包括的参考信号具体可以是该配置信息用于指示W个用于信道测量的资源集合，该W个资源集合中的每个资源集合包括多个参考信号，且该W个资源集合中的第一资源集合中的参考信号与该第W个资源集合中除该第一资源集合外的其他资源集合中的每个资源集合中的参考信号具有映射关系，终端可以将具有映射关系的参考信号确定为该N个参考信号组中的一个参考信号组，其中，W≥2，且W为整数。
具体地，网络设备发送配置信息，该配置信息用于指示W个用于信道测量的资源集合，每个资源集合包括多个参考信号。不同资源集合包括的参考信号数目可以相同，也可以不相同。该W个资源集合中的任意一个资源集合(例如，第一资源集合)包括的参考信号与除该第一资源集合之外的其他资源集合中的至少一个资源集合中的参考信号具有映射关系。
应理解，本申请实施例可以应用于上述N个参考信号组的M个同时接收的参考信号为网络设备同时发送的参考信号。
可选地，若不同资源集合包括的参考信号数目相同，则第一资源集合包括的参考信号与除该第一资源集合之外的其他资源集合中的每个资源集合中的参考信号可以一一映射，将具有映射关系的参考信号可以确定为该N个参考信号组中的一个参考信号组。
可选地，W个资源集合的时频资源位置是频分复用(FDM)的。
更进一步的，满足一一映射关系的参考信号的时频资源是FDM的。或者说满足一一映射关系的参考信号为承载所述参考信号的时频资源FDM的参考信号。
例如，如图4所示，配置信息包括两个资源集合，分别为资源集合1和资源集合2，资源集合1包括4个参考信号(分别为参考信号1、参考信号2、参考信号3和参考信号4)，资源集合2也包括4个参考信号(分别为参考信号5、参考信号6、参考信号7和参考信号8)，资源集合1中的4个参考信号和资源集合2中的4个参考信号一一映射，例如，参考信号1和参考信号5具有映射关系，参考信号2和参考信号6映射关系，参考信号3和参考信号7具有映射关系，参考信号4和参考信号8具有映射关系。这样，参考信号1和参考信号5可以是一个资源组合，参考信号2和参考信号6可以是一个资源组合，参考信号3和参考信号7可以是一个资源组合，参考信号4和参考信号8可以是资源组合。
可选地，该配置信息还可以用于指示W个用于信道测量的资源配置，每个资源配置包括多个参考信号。不同资源配置包括的参考信号数目可以相同，也可以不相同。该W个资源配置中的任意一个资源配置(例如，第一资源配置)包括的参考信号与除该第一资源配置之外的其他资源配置中的至少一个资源配置中的参考信号具有映射关系。
具体地，资源配置包括一组参考信号资源集合以及资源类型(例如时域类型，时域类 型包括周期，非周期，半周期)，此时该资源配置信息可以是RRC信令，可选地再通过向UE发送MAC-CE和或DCI信令指示其中一个或多个资源集合。
应理解，本申请实施例可以应用于上述N个参考信号组的M个同时接收的参考信号为网络设备同时发送的参考信号。
302，终端发送指示信息，该指示信息用于指示K个参考信号组中的每个参考信号组中的至少一个参考信号的信道状态信息，该K个参考信号组是该N个参考信号组中的至少一个，其中，1≤K≤N，且K为整数。相应地，网络设备接收该指示信息。
具体地，终端接收网络设备发送的N个参考信号组，每个参考信号组包括多个能够同时接收的参考信号，终端将至少一个参考信号的信道状态信息的指示信息反馈给网络设备，该至少一个参考信号可以属于该N个参考信号组中的K个参考信号组。也就是说，在存在多个能同时接收到参考信号的场景中，终端可以反馈参考信号的信道状态信息，使得网络设备可以在能够同时发送的多个波束中选择波束发送数据，这样在选择的波束数目大于一个的情况下，有助于提高通信效率；在从多个波束中选择通信质量高的波束的情况下能够提高通信质量；在反馈至少一个参考信号的信道状态信息时，若该至少一个参考信号的数目小于对应的参考信号组的总数目的情况下，可以节省信令开销。
需要说明的是，该至少一个参考信号即每个参考信号组中需要在指示信息中携带其信道状态信息的参考信号的数目。
还需要说明的是，该K个参考信号组中不同参考信号组包括的该至少一个参考信号的数目不同。此外，该至少一个参考信号的数目与该至少一个参考信号的信道状态信息的数目可以相同也可以不相同，例如，3个参考信号的信道状态信息可以是3个，可以是其他值，本申请对此不进行限定。
应理解，K个参考信号组也可以是看作N个参考信号组的子集。
可选地，终端可以根据该N个参考信号组中的参考信号的信道质量和/或传输方式，确定该K个参考信号组和/或该K个参考信号组中每个参考信号组中的该至少一个参考信号。
具体地，终端可以根据该N个参考信号组中的参考信号的信道质量的高低，确定指示信息携带哪些参考信号的信道状态信息。例如，终端可以确定哪些参考信号组，以及参考信号组内的哪些参考信号。
可选地，终端可以根据N个参考信号组中的至少一个参考信号组中每个参考信号组中的至少一个子集的信道质量确定该K个参考信号组和/或该K个参考信号组中每个参考信号组中的该至少一个参考信号。
具体地，一个参考信号组(例如，第一参考信号组)包括多个参考信号，该多个参考信号的任意至少一个参考信号进行组合为该第一参考信号组的子集。终端可以根据该N个参考信号组中每个参考信号组中的所有子集的信道质量选择每个参考信号组中的一个目标子集，再根据每个参考信号组中的目标子集的信道质量从N个参考信号组中选择K个参考信号组，并将该K个参考信号组中的目标子集包括的参考信号的信道状态信息通过指示信息发送给网络设备，这样网络设备可以根据该目标子集中的参考信号对应的波束进行同时发送数据，换句话说，终端向网络设备推荐了网络设备发送数据的传输方式，提高了通信质量。
需要说明的是，一个参考信号组(例如，第一参考信号组)中的部分子集可以不参与上述的选择过程，这样终端可以根据该第一参考信号组中的部分子集选择目标子集，本申请对此不进行限定。同样，该N个参考信号组中的部分参考信号组也可以不参与上述选择过程，这样终端可以根据N个参考信号组中的部分参考信号组选择K个参考信号组。
应理解，一个子集的信道质量即该子集包括的所有参考信号的等效的信道质量，即假设网络设备只同时发送该子集内的参考信号测量得到的等效信道质量。
可选地，本申请实施例中的信道质量可以是参考信号接收质量(reference signal received quality，RSRQ)，也可以是信号干扰噪声比(signal to interference plus noise ratio，SINR)。
可选地，终端可以根据N个参考信号组中的至少一个参考信号组中每个参考信号组中的至少一个子集的信道质量和传输方式，确定该K个参考信号组和/或该K个参考信号组中每个参考信号组中的该至少一个参考信号。
具体地，传输方式可以是网络设备同时发送信号的发送波束的数目，即不同的传输方式指示网络设备同时发送信号的发送波束的数目不同。或者说，传输方式是同时服务的基站的个数(TRP的个数)。例如，传输方式包括波束(beam)个数的指示，或者说通说参考信号个数的指示，或者是同时服务的TRP的个数，或者只是数据传输(DPS)或者非相干联合传输(Incoherent joint transmission，NCJT)传输。终端可以结合该传输方式，确定目标子集。也就是说，终端选中的目标子集包括的数目只能是该传输方式指示发送波束的数目，这种情况下，终端只需要根据每个参考信号组中包括传输方式指示的发送波束的数目的子集的信道质量，选择目标子集。
应理解，该传输方式可以是动态信令或者半静态信令指示的，那么在不同的时刻，网络设备可以指示不同的传输方式。若参考信号的信息的指示是比该信令更长期或更慢的信令指示的，那么此时UE某一时刻需要根据该传输方式指示信息在多个同时传输的参考信号中选则几个上报给网络设备。UE在另一时刻不需要在同时传输的参考信号中做选择。
应理解，该传输方式可以是网络设备为预先终端配置的，也可以是网络设备与某个终端预先约定的，本申请对此不进行限定。
可选地，终端还可以只根据传输方式，确定该K个参考信号组和/或该K个参考信号组中每个参考信号组中的该至少一个参考信号。
具体地，若传输方式指示的发送波束的数目为参考信号组中包括的所有参考信号的数目，且K＝M的情况下，则终端只能选择将参考信号组中的所有参考信号作为该至少一个参考信号。
可选地，若该K个参考信号组中的第i个参考信号组中的所述至少一个参考信号为Li个，即终端选中的目标子集包括Li个参考信号，其中1≤i≤K，1≤Li≤M,且i，Li均为整数。这样该Li个参考信号的信道状态信息可以包括以下内容中的至少一项：X个参考信号的资源索引，Y个参考信号接收质量RSRQ，参考信号的个数，其中，X≤Li,Y≤Li。
具体地，参考信号的资源索引用于指示参考信号的时域和或频域和或空域资源，例如(CSI-RS resource indicator，CRI))或CSI-RS resource index用于指示CSI-RS的时域和或频域和或空域资源。参考信号的个数即该第i个参考信号组中的目标子集包括的参考 信号的数目。参考信号的信道状态信息可以是资源索引、RSRQ和参考信号个数中的至少一项，即参考信号的信道状态信息可以包括资源索引；资源索引和RSRQ；RSRQ；RSRQ和参考信号的个数；资源索引和参考信号的个数；资源索引、RSRQ和参考信号的个数中的任一项。例如，Li个参考信号的信道状态信息可以包括Li个参考信号分别对应的资源索引、Li个参考信号中每个参考信号的RSRQ以及参考信号的数目(即Li)。可选地，Li个参考信号的信道状态信息包括的资源索引的数目X可以小于Li，Li个参考信号的RSRQ的数目Y也可以小于Li。
需要说明的是，在具体实现的过程中，指示信息包括的内容是上述任一种，网络设备和终端可以预先约定指示信息包括的内容，从而有助于网络设备能够正确解析该指示信息。
需要说明的是，该i的取值可以是1<i<K，即该K个参考信号组中的第1个参考信号组中的该至少一个参考信号的个数为L1，该K个参考信号组中的第2个参考信号组中的该至少一个参考信号的个数为L2，依次类推，且不同参考信号组中的该至少两个参考信号可以不同，即L1与L2的取值不同。
还需要说明的是，参考信号的资源索引可以是独立的为每个参考信号在所在参考信号集合中统一编码，如W个资源集合的第一资源集合编号1到4，第二资源集合编号1到4，上报资源集合的索引或标识以及集合内参考信号的索引即可。或者统一编号为1到8。也可以是组内编号。
应理解，“参考信号的资源索引”也可以称为“参考信号资源标识”。
还应理解，在K≥2的情况下，该指示信息中的参考信号的个数可以是K个参考信号组中每个参考信号组各自包括的目标子集中参考信号的数目，也可以是K个参考信号组中每个参考信号组中各自包括的目标子集中参考信号数目的总和。
可选地，在第i个参考信号组中的Li个参考信号具有映射关系的情况下，X<Li，更具体地，若根据Li中的一个资源索引可以获知Li中的其他资源索引，则X可以取值为1。
这样网络设备接收一个参考信号的资源索引后可以通过该映射关系找到其它同时传输的参考信号。也就知道了后面的信道质量对应的是哪些参考信号的了。
可选地，Li个参考信号的RSRQ可以通过Y个等效的RSRQ体现的情况下，Y<Li，更具体地，若通过一个等效的RSRQ体现该Li个参考信号的RSRQ，则Y＝1。
需要说明的是，在终端发送的指示信息通过等效的RSRQ体现的情况下，该指示信息还可以包括该Li个参考信号的参考信号接收功率(reference signal received power，RSRP)，这样可以使得网络设备根据等效的RSRQ和该Li个参考信号的RSRP还可以得到该Li个参考信号中的每个参考信号的RSRQ。
可选地，若配置信息用于指示W个资源集合，该W个资源集合中至少有一个资源集合的重复(repetition)参数为“off”，和该资源集合中至少有一个资源集合的repetition参数为“on”,终端设备会从所述资源集合中选择K个参考信号组的中的至少一个参考信号的指示信息上报给基站。此时，指示信息至少包括参考信号资源索引。
应理解，本申请实施例可以应用于上述N个参考信号组的M个同时接收的参考信号为网络设备同时发送的参考信号。
可选地，在上述资源配置方式中，终端设备假设网络设备的发送空域滤波器不同或 者终端设备的接收滤波器相同。
可选地，在上述资源配置方式中，所述W个资源集合中的资源有一一映射关系，那么此时该W个资源集合可以用于多波束(multi-beam)传输的基站侧发送波束训练。所述multi-beam传输是指同时传输的多个波束或信号。
应理解，所述W个资源集合中参考信号资源集合满足频分复用FDM关系的才有一一映射关系。
可选地，当终端设备上报K个参考信号组中的至少一个参考信号的信息为Li＝W时，终端设备上报每个参考信号组的指示信息时，可以仅上报其参考信号资源集合为“off”类型的参考信号的索引。传统方案中只能通过“off”类型的一个资源集合训练基站侧的发送波束，但是无法训练能同时传输的多个波束，以指导后续数据或信号的传输方式，后续数据或信号的同时传输，因此，本申请实施例同时传输的波束可以提高系统的覆盖或提高系统的空分复用增益，进一步提高系统性能，同时传输的波束训练对于整个系统至关重要。
应理解，若所述W个资源集合之前不全是FDM的，或者至少有两个资源完全是TDM的，那么可能还需要上报资源集合的索引。
例如：当W等于2时，该配置信息配置一个参考信号资源集合的repetition参数为“off”的参考信号资源集合，和一个参考信号资源集合的repetition参数为“on”的参考信号资源集合。该集合可用于基站发送波束的训练。
可选地，若配置信息用于指示2个资源集合，该2个资源集合每个资源集合包括的都是混合类型的信号，即“on+off”类型的信号，则在K个参考信号组为多个参考信号组的情况下，上报“on”类型的参考信号的组标识和off类型参考信号的组标识、off类型的参考信号的资源索引，以及等效的RSRQ或SINR。
应理解，“on”类型的参考信号的发送波束相同，因此可以通过“on”类型的参考信号的组标识表示发送波束相同的多个参考信号。
可选地，若配置信息用于指示W个资源集合，该W个资源集合中的资源集合的repetition参数均为“on”,终端设备会从所述资源集合中选择K个参考信号组的中的至少一个参考信号的指示信息上报给基站或者不上报。
应理解，可选地，所述参考信号状态信息不包括参考信号资源索引，包括信道质量信息。
应理解，可选地，在上述资源配置方式中，所述W个资源集合中的资源有一一映射关系，那么此时该W个资源集合可以用于multi-beam传输的终端侧接收波束训练。所述multi-beam传输是指同时传输的多个波束或信号。
应理解，所述W个资源集合中参考信号资源集合满足频分复用FDM关系的才有一一映射关系。
应理解，若所述W个资源集合之前不全是FDM的，或者至少有两个资源完全是TDM的，那么可能还需要上报资源集合的索引。
可选地，该K个参考信号组中的第i个参考信号组中的所述至少一个参考信号为Li个，1≤i≤K，1≤Li≤M,且i，Li均为整数，该Li个参考信号的信道状态信息包括以下内容中的至少一项：X个参考信号的资源索引，Z个信号干扰噪声比SINR，参考信号的个数，其中，X≤Li,Z≤Li。
具体地，信道质量可以通过RSRQ体现，也可以通过信号干扰噪声比(signal to interference plus noise ratio，SINR)体现，本申请实施例可以是将上述实施例中的Y个RSRQ替换为Z个SINR实现，为避免重复，在此不进行赘述。其中Y可以与Z的取值相同，也可以不相同，本申请对此不进行限定。
可选地，指示信息中的X个参考信号的资源索引和/或该Y个RSRQ和指示信息中的参考信号的个数可以独立编码；或者指示信息中的X个参考信号的资源索引和/或该Z个SINR和指示信息中的参考信号的个数可以独立编码。
具体地，指示信息可以包括两个部分，第一部分为参考信号的数目，第二部分为X个参考信号的资源索引和/或该Y个RSRQ，或者第二部分为X个参考信号的资源索引和/或该Z个SINR。网络设备在解析指示信息时可以先解析第一部分，再解析第二部分，这样网络设备根据先解析出的参考信号的个数的大小，可以确定解析第二部分需要使用资源的大小，避免采用固定的资源统一解析指示信息的全部内容造成的资源浪费，即独立编码能够减少网络设备解析指示信息的资源开销。
例如，参考信号的个数由Q1个比特表示，X个参考信号的资源索引和/或所述Y个RSRQ由Q2个比特表示，所述终端设备对Q1个比特进行编码获得第一信息，对Q2个比特进行编码获得第二信息，则指示信息包括所述第一信息与第二信息。相应地，网络设备根据指示信息中承载参考信号的个数的比特进行解码获得参考信号的个数。网络设备根据参考信号的个数，对第一指示信息中的用于承载X个参考信号的资源索引和/或所述Y个RSRQ的比特进行解码获得所述X个参考信号的资源索引和/或所述Y个RSRQ。
需要说明是，指示信息中的第一部分包括X个参考信号的资源索引和/或该Y个RSRQ，即终端向网络设备发送的指示信息若只包括X个参考信号的资源索引的情况下，该指示信息的第一部分就只包括X各参考信号的资源索引；若只包括Y个RSRQ，则该指示信息的第一部分就只包括Y个RSRQ，也就是说，指示信息的第一部分的全部内容与第二部分进行独立编码。
可选地，若第i个参考信号组中的该至少一个参考信号为一个(例如，第一参考信号)，即Li＝1，则该第一参考信号的RSRQ可以根据第一RSRP和第一接收信号强度指示(received signal strength indicator，RSSI)确定，其中，第一RSRP为对第一参考信号所在的参考信号资源进行RSRP测量得到的，第一RSSI为对第一参考信号所在的参考信号资源进行RSSI测量得到的，或该第一RSSI为对第一参考信号和第二参考信号所在的参考信号资源进行RSSI测量得到的，该第二参考信号不属于该第i个参考信号组。
具体地，终端也可以在第一参考信号所在的参考信号资源上进行RSSI测量得到第一RSSI，或者终端可以在第一参考信号和第二参考信号所在的参考信号资源测量其他小区对该终端的干扰得到该第一RSSI。终端可以在第一参考信号所在的参考信号资源上进行RSRP测量得到第一RSRP，进而根据该第一RSSI和第一RSRP确定第一参考信号的RSRQ。
需要说明的是，该第二参考信号不属于该第i个参考信号组可以是第二参考信号不属于所述N个参考信号组，或者，第二参考信号为第i个小区组的资源标识最大或者最小的一个参考信号，或者第二参考信号为N个小区组的资源标识最大或者最小的一个参考信号，或者，第二参考信号为第一个小区组的资源标识最大或者最小的一个参考信号。
可选地，网络设备可以预先配置用于测量RSRP的参考信号资源和/或用于测量RSSI的参考信号资源，也可以是与终端预先约定用于测量RSRP的参考信号资源和/或用于测量RSSI的参考信号资源，本申请对此不进行限定。
具体地，网络设备可以发送配置信息，该配置信息用于指示第一参考信号所在的参考信号资源用于测量RSRP，第一参考信号和第二参考信号所在的参考信号资源用于测量RSSI，或者第一参考信号所在的参考信号资源也用于测量RSSI。
可选地，该根据该第一RSSI和第一RSRP确定第一参考信号的第一RSRQ可以是第一RSRQ＝第一RSRP/第一RSSI。
可选地，若第i个参考信号组中的该至少一个参考信号为一个(例如，第一参考信号)，即Li＝1，则该第一参考信号的第一SINR可以根据第一信道信息和第一干扰信息确定，该第一信道信息是对该第一参考信号所在的参考信号资源进行信道测量得到的，该第一干扰信息为对该第一参考信号或第二参考信号所在的参考信号资源进行干扰测量得到的，该第二参考信号不属于该第i个参考信号组。
可选地，该第一参考信号的第一SINR根据第一信道信息S和第一干扰信息I确定可以是SINR＝S/I。
可选地，若第i个参考信号组中的该至少一个参考信号为多个参考信号，即，Li>1，则该Li个参考信号中的任意一个参考信号(例如，第j个参考信号)的第二RSRQ可以根据第二RSRP和第二RSSI确定。该第二RSRP是对该第j个参考信号进行RSRP测量得到的，该第二RSSI是对该Li个参考信号所在的参考信号资源上进行RSSI测量得到的，或该第二RSSI是对该Li个参考信号和第二参考信号所在的参考信号资源上进行RSSI测量得到的，该第二参考信号不同于该第i个参考信号组的该Li个参考信号。
具体地，第j个参考信号为Li个参考信号中的任意一个参考信号，这样Li个参考信号中的每个参考信号都可以按照第j个参考信号的方式确定对应的RSRQ。为避免重复，在此不进行赘述。
可选地，第二RSRQ＝(RSRPj)/(RSRP1+RSRP2+…+RSRPj+I)，其中所述I为除所述Li个参考信号所在的小区外的其他小区对该终端的干扰，还可以包括噪声，该干扰信息可以通过Li个参考信号中的一个参考信号测量干扰得到，或者通过第二参考信号测量得到。
可选地，上述噪声可以通过所述Li个参考信号的测量得到，如Li个参考信号中的两两个参考信号的接受信号或接收质量或接收功率相减后，将相减的结果相加取平均得到所述噪声。
需要说明的是，该第二RSSI的测量与第一RSSI的测量的不同在于，第二RSSI的测量是对该Li个参考信号所在的参考信号资源上进行RSSI测量得到的，即需要考虑该Li个参考信号之间的相互干扰。
例如，如图5所示，以Li＝2(即CSI-RS1和CSI-RS2)为例进行说明，终端在CSI-RS1上的参考信号资源(CSI-RS1)上接收到信号y1为h1*s1与h22*s2+I1+n的和，其中h1表示CSI-RS1所在的TRP1到终端在CSI-RS1的信道，h22表示TRP2到终端在CSI-RS2的信道，s1表示参考信号1，s2表示参考信号2，该s1对于TRP1和终端来说是已知信息，该s2对于TRP2和终端来说是已知信息，I1表示终端在CSI-RS1上收到的除该Li个 信号以外的来自其他小区的干扰(例如，TRPn)，n表示噪声。终端在CSI-RS2的参考信号资源上接收到信号y2＝h2*s2+h11*s1+I2+n，其中h2为CSI-RS2所在TRP2到终端的在时频资源CSI-RS2的信道系数，h22为CSI-RS1所在TRP1到终端的在时频资源CSI-RS1的信道系数，通常而言，h1＝h11，h2＝h22。终端根据信道估计算法得到信道系数矩阵h1，进而根据h1得到h1的RSRP1，其中RSRP1＝h1x h1 H或者h1 Hx h1，h1 H为h1的转置矩阵。相应地，根据h2得到h2的RSRP2。这样，CSI-RS1的RSRQ＝RSRP1/(RSRP1+RSRP2+I)，CSI-RS2的RSRQ＝RSRP2/(RSRP1+RSRP2+I)，其中，I＝(I1+n+I2+n)/2，I1+n为终端通过CSI-RS1测量得到，I2+n为终端通过CSI-RS2测量得到。
可选地，干扰可以通过CSI-RS1测量得到I＝I1+n。可选地，干扰可以通过CSI-RS2测量得到I＝I2+n。
需要说明的是，RSSI＝RSRP1+RSRP2+I。
可选地，第j个参考信号的第二RSRQ根据第二RSRP和第二RSSI确定可以是第二RSRQ＝第二RSRP/第二RSSI。
可选地，若第i个参考信号组中的该至少一个参考信号为多个参考信号，即，Li>1，该Li个参考信号中的第j个参考信号的第二SINR可以是根据第二信道信息和第二干扰信息确定，该第二信道信息是对第j个参考信号所在的参考信号资源进行信道测量得到的，该第二干扰信息是对该Li个参考信号所在的参考信号资源进行干扰测量得到的，或该第二干扰信息是由对该Li个参考信号中除第j个参考参考信号外的参考信号所在的参考信号资源进行干扰测量得到的，或，该第二干扰信息是由对该Li个参考信号中除第j个参考参考信号外的参考信号和第二参考信号所在的参考信号资源进行干扰测量得到的，该第二参考信号不同于该第i个参考信号组的该Li个参考信号。
具体地，若第二RSSI的测量是对该Li个参考信号所在的参考信号资源上进行RSSI测量得到的，即需要考虑该Li个参考信号之间的相互干扰，从而准确的确定出每个参考信号的通信质量，更进一步提高通信质量。若第二RSSI的测量还需要考虑其他小区对终端的影响，从而更准确的确定出每个参考信号的通信质量，更进一步提高通信质量。
可选地，第二SINR＝(Sj)/(S1+S2+…+Sj+I)，其中所述I为除所述Li个参考信号所在的小区外的其他小区对该终端的干扰，还可以包括噪声，该干扰信息可以通过Li个参考信号中的一个参考信号测量干扰得到，或者通过第二参考信号测量得到。Sj为第j个参考信号上测量得到的信道信息或称为信道功率。
需要说明的是，该第二参考信号可以是零功率参考信号，也可以是非零功率参考信号，本申请对此不进行限定。
可选地，若第i个参考信号组中的该至少一个参考信号为多个参考信号，即，Li>1，终端可以根据Li个第三RSRP和第三RSSI确定一个等效的RSRQ(例如通过第三RSRQ表示)，该Li个第三RSRP为对该Li个参考信号中的每个参考信号所在的参考信号资源进行RSRP测量得到的，该第三RSSI为对该Li个参考信号所在的参考信号资源进行RSSI测量得到的，或，该第三RSSI为对该Li个参考信号和第二参考信号所在的参考信号资源进行RSSI测量得到的，该第二参考信号不属于该N个参考信号组。
应理解，在本申请实施例中，第i个参考信号组中的该至少一个参考信号的信道状态信息可以是只有一个等效的RSRQ。
可选地，根据Li个第三RSRP和第三RSSI确定第三RSRQ可以是根据第三RSRQ与Li个第三RSRQ以及第三RSSI之间的函数关系确定的，即第三RSRQ＝f(Li个第三RSRP，第三RSSI)。
可选地，若第i个参考信号组中的该至少一个参考信号为多个参考信号，即，Li>1，该第三SINR可以是根据Li个第三信道信息和第三干扰信息，该Li个第三信道信息是由对该Li个参考信号中的每个参考信号所在的参考信号资源进行信道测量得到的，该第三干扰信息是由对该Li个参考信号所在的参考信号资源进行干扰测量得到的，或，该第三干扰信息是由对该Li个参考信号和第二参考信号所在的参考信号资源进行干扰测量得到的。
可选地，若第i个参考信号组中的该至少一个参考信号为多个参考信号，即，Li>1，终端可以根据第四RSRP和第四RSSI，确定第四RSRQ，该第四RSRP为对该Li个参考信号中的每个参考信号进行RSRP测量得到的Li个RSRP的最大值，该第四RSSI为对该Li个参考信号所在的参考信号资源进行RSSI测量得到的，或，该第四RSSI为对该Li个参考信号和第二参考信号所在的参考信号资源进行RSSI测量得到的，该第二参考信号不属于该N个参考信号组。
