其中，本公开实施例涉及的终端，可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中，终端设备的名称可能也不相同，例如在5G系统中，终端设备可以称为用户设备(User Equipment，UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信，无线终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service， PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)、Redcap终端等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device)，本公开实施例中并不限定。
本公开实施例涉及的网络设备，可以是基站，该基站可以包括多个为终端提供服务的小区。根据具体应用场合不同，基站又可以称为接入点，或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备，或者其它名称。网络设备可用于将收到的空中帧与网际协议(Internet Protocol，IP)分组进行相互更换，作为无线终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如，本公开实施例涉及的网络设备可以是全球移动通信系统(Global System for Mobile communications，GSM)或码分多址接入(Code Division Multiple Access，CDMA)中的网络设备(Base Transceiver Station，BTS)，也可以是带宽码分多址接入(Wide-band Code Division Multiple Access，WCDMA)中的网络设备(NodeB)，还可以是长期演进(long term evolution，LTE)系统中的演进型网络设备(evolutional Node B，eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB)、6G中的基站，也可以是家庭演进基站(Home evolved Node B，HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等，本公开实施例中并不限定。在一些网络结构中，网络设备可以包括集中单元(centralized unit，CU)节点和分布单元(distributed unit，DU)节点，集中单元和分布单元也可以地理上分开布置。

信道状态信息上报中，首先需要指出的是，码本参数的维度M v在上报过程中，无法有效地确定适当数量的频域基向量，导致终端反馈的开销大，针对于此，本申请提供一种信道状态信息上报方法，应理解，本申请中的信道状态信息上报方法，可以但不限于应用于Rel-17端口中码本参数信息的上报。
请参见图2，图2是本公开实施例提供的一种信息上报方法的流程图，如图2所示，所述方法包括以下步骤：
步骤201、终端估计下行信道信息。
其中，终端可以根据网络设备发送的导频信号估计下行信道信息。例如，网络侧通过P个端口向终端发送波束赋形的导频信号(CSI Reference Signal，CSI-RS),网络侧给终端侧配置K个包含频域基向量的窗或者集合，其中K≥1，并且窗或者集合的大小为N k,k＝1,…,K。终端根据接收到的P个端口波束赋形的CSI-RS估计下行信道信息。
步骤202、所述终端根据所述下行信道信息，确定频域基向量信息。
步骤203、所述终端向网络设备发送所述频域基向量信息。
上述的信息上报方法中，终端估计下行信道信息，终端根据下行信道信息，确定频域基向量信息。终端向网络设备发送频域基向量信息，这样，相比于相关技术中，终端根据网络设备配置的频域基向量集合上报频域基向量信息，容易出现上报多余频域基向量信息，导致终端开销浪费的情况，在本申请中，由终端根据下行信道信息确定频域基向量信息，可以使确定的频域基向量信息更加准确，从而可以减小终端的反馈开销。
需要指出的是，在一些可行的实施方式中，频域基向量信息包括频域基向量的数量、频域基向量对应的指示信息、或者目标指示内容中的至少一项，其中，频域基向量对应的指示信息用于指示所述终端从网络设备配置的所述频域基向量集合中选择的频域基向量，或者，从终端中预设的频域基向量集合中选择的频域基向量，所述目标指示内容包括所述频域基向量集合或预设频域基向量。
例如，终端中预设的频域基向量集合可以是终端根据有效信道确定的候选的频域基向量的集合，目标指示内容可以是1bit的指示信息，终端可以通过该1bit的指示信息表示终端发送的频域基向量信息是采用的网络侧配置的频域基向量集合中的或是预设频域基向量。该实施方式中，预设频域基向量可以是一个元素全为1的频域基向量。其中，频域基向量的长度可根据CQI子带大小和网络配置的参数R确定。更具体地，当有Z层传输层时，可以通过Zbits的指示信息进行表示。此处仅做示例，不做限定，在其他可行的实施方式中，还可以采用其他的指示信息，只需其能表示终端上报的频域基向量信息的选择是由网络设备配置还是由终端确定即可。但不论其作何变换，都在本申请实施方式保护的范围之内。
具体而言，在一个可行的实施方式中，频域基向量信息包括频域基向量的数量，换言之，终端向网络设备发送的是频域基向量的数量。可变换地，在另一个可行的实施方式中，频域基向量信息包括频域基向量的指示信息，换言之，终端向网络设备发送的是终端从频域基向量集合中选择的频域基向量。在该实施方式中，频域基向量集合可以由网络侧设备对终端配置，其具体配置方式将在下文中详述。可变换地，在又一个可行的实施方式中，频域基向量信息包括频域基向量的数量和频域基向量对应的指示信息，换言之，终端向网络设备发送的是频域基向量的数量和终端从频域基向量集合中选择的频域基向量。可变换地，在其他可行的实施例中，频域基向量信息还可以包括其他的信息。此处仅做示例，不做限定，但不论其作何变换，都在本申请实施方式保护的范围之内。
在一些可行的实施方式中，终端可以确定频域基向量信息。
可选的，终端根据下行信道信息，确定频域基向量信息，包括：
终端根据下行信道信息计算预设频域基向量中每一频域基向量对应的压缩系数；
终端根据压缩系数确定频域基向量信息。
频域基向量信息为频域基向量的数量为例，终端根据下行信道信息，确定频域基向量信息的步骤如下所示：首先，终端根据上述步骤中接收的P个端口的CSI-RS，估算出各个端口的下行道信息作为有效信道，对于第p个端 口，在N 3个频域单元上所估计的有效信道记为
Figure PCTCN2022081482-appb-000001
假设终端中根据有效信道确定的候选的频域基向量个数为N 3，计算第n个频域基向量f n对应的压缩系数，其计算公式可以满足如下关系式：
Figure PCTCN2022081482-appb-000002
然后通过遍历的方式计算出所有的频域基向量的压缩系数c′ p,n，其中，p＝1,…,P；n＝1,…,N 3。
进一步地，根据上述步骤计算得到的压缩系数c′ p,n确定M v的值。例如，可以根据压缩系数最小的频域基向量确定M v的值。
在一些可行的实施方式中，终端可以根据网络侧设备配置的频域基向量集合确定频域基向量信息。可选的，终端根据下行信道信息，确定频域基向量信息之前，上述的方法还包括：
终端接收网络设备配置的频域基向量集合；
终端根据下行信道信息，确定频域基向量信息，包括：
终端根据下行信道信息和频域基向量集合确定频域基向量信息。
在该实施方式中，终端根据下行信道信息和频域基向量集合确定频域基向量信息，可以确定合适数量的频域基向量，例如，当网络设备配置的频域基向量的值为4，而终端根据下行道信息确定的频域基向量的值为2时，此时，终端确定频域基向量的值为2，终端向网络侧设备上报M v的值为2，这样，可以避免向网络设备上报多余数量的频域基向量而造成的终端反馈开销浪费。
可选的，终端根据下行信道信息和频域基向量集合确定频域基向量信息，包括：
终端根据下行信道信息，计算频域基向量集合中每一频域基向量对应的压缩系数；
终端基于压缩系数确定频域基向量信息。
在该实施方式中，终端根据下行信道信息和频域基向量集合，确定频域基向量信息的步骤如下所示。
首先，终端根据上述步骤中接收的P个端口的CSI-RS，估算出各个端口的下行道信息作为有效信道，对于第p个端口，在N 3个频域单元上所估计的 有效信道记为
Figure PCTCN2022081482-appb-000003
然后，将网络设备对终端配置的频域基向量集合记为N，f n为配置的频域基向量集合中第n个频域基向量，采用上述公式计算频域基向量集合中每一个频域基向量对应的压缩系数c′ p,n，其中，p＝1,…,P；n＝1,…,N。
进一步地，根据上述步骤计算得到的压缩系数c′ p,n确定M v的值。例如，可以根据压缩系数最小的频域基向量确定M v的值。
在一些可行的实施方式中，网络设备可以向终端配置码本参数，并向终端发送触发状态，通过码本参数和触发状态关联对应的方式指示终端选择频域基向量信息。其中，网络设备向终端发送触发状态，终端根据触发状态确定上报的上报方式和码本参数的具体步骤如下所示。
可选的，终端接收网络设备配置的频域基向量集合之后，上述方法还包括；
终端接收网络设备发送的触发状态，触发状态用于指示终端的上报方式，还用于指示网络设备向终端配置的码本参数，码本参数包括频域基向量集合、频域基向量集合的大小或者频域基向量集合的起始点信息中的一种或多种；
终端根据触发状态确定码本参数。
在该实施方式中，终端根据触发状态确定码本参数的步骤具体如下。
首先，值得指出的是，W f通过网络设备配置给终端时，配置方法可以是，网络设备为终端配置一个窗或集合的起始点M initial和一个包含N≥M v个频域基向量的窗或集合，或者，终端在窗或集合内连续N个频域基向量选择M v个，参数M v也可由网络设备配置。高层信令无线资源控制(Radio Resource Control，RRC)或MAC层控制单元(MAC Control Element，MAC-CE)配置给终端配置的参数M initial、N或M v可能包含一组多个候选值，或者高层信令RRC或MAC-CE配置多个集合，每个集合包含参数M initial、N和M v中的两个或三个。如果通过在DCI中增加信息域用于这些信息，将增加DCI的开销。因此，需要在不增加DCI开销的情况下，确定上述的码本参数。
具体地，用于上行调度的DCI格式中包含DCI 0_1和DCI 0_2。在这两种格式的DCI域中包含一个0～6bits的CSI请求域，该域的长度是通过RRC信令中CSI请求域的信息长度(reportTriggerSize)的配置。CSI的请求域激 活一个触发状态，该触发状态对应一个或多个CSI上报，上报内容包括CSI-RS资源指示(CSI-RS Resource Indicator，CRI)/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。
终端的上报方式包括非周期CSI上报和半持续CSI上报，非周期CSI上报采用MAC CE结合DCI的方式进行配置和触发，并基于物理上行共享信道(Physical Uplink Shared Channel，PUSCH)上报。RRC配置多个CSI触发状态。每个触发状态对应一个或多个CSI上报。DCI格式0_1/0_2中的CSI请求域的大小可由RRC信令配置为0～6bits，因此最多可以指示63个CSI触发状态(有一个保留状态)。RRC最多可以配置128个CSI触发状态，当RRC配置的CSI触发状态超过63时，由MAC CE信令将其中的63个CSI触发状态映射至CSI请求域指示。每个触发状态可以关联至1、2、3个非周期resource setting(资源集合)，其中，若resource setting中包含多个非周期resource set(资源集)，则只选择其中一个resource set，每个resource set包含多个CSI-RS资源，如图3所示。其中PMI是根据与该CSI上报相关联的resource setting包含的用于CMR的CSI-RS资源计算。
而，基于PUSCH的SP-CSI，类似于上述的非周期CSI上报，也是由DCI信令激活和去激活。在CSI反馈框架下，RRC配置多个触发状态(trigger state)，最大64个触发状态，且每个触发状态对应一个CSI reporting setting。使用DCI中的CSI请求域激活一个触发状态。且同一时刻可以有多个处于激活状态的基于PUSCH的SP-CSI。不同于非周期的CSI上报，半持续CSI上报中的PMI是根据DCI触发之前与DCI最近邻的一个CMR的CSI-RS资源计算，该CSI-RS资源包含在与DCI触发相关联的CSI resource setting中。
目前，高层信令RRC或MAC-CE配置给终端配置的参数M initial、N或M v可能包含一组多个候选值，或者高层信令RRC或MAC-CE配置多个包含多种参数构成的集合。目前还没有相应的码本参数指示方法。如果采用通常的做法直接增加DCI的信息域用于指示，将增加DCI的开销。
因此，在该实施方式中，为了减小DCI的开销，采用码本参数与DCI的触发状态相关联的方式确定码本参数，具体步骤如下。
步骤1：网络设备通过高层信令RRC或MAC-CE给终端配置码本参数至少包括M v、N和M initial的一种或多种参数，或者配置了多种参数的组合。每种参数包含X≥1个候选值，或者候选的参数组合有X≥1个。网络设备给终端的每个CSI上报配置了S≥1触发状态。
步骤2：网络设备发送DCI中CSI请求域激活一个触发状态，该触发状态不仅指示了K≥1个非周期或基于PUSCH的半持续CSI上报，还指示了步骤1中所述的一种或多种参数值，或者一个多种参数的组合。
步骤3：终端根据网络设备配置和/或DCI指示确定码本参数M v/N/M initial的取值。
步骤4：终端利用指示的码本参数计算CRI/RI/PMI/CQI信息并通过相应的CSI上报给网络侧。
在该实施方式中，通过DCI中的CSI请求域激活的触发状态与码本参数信息实现联合编码指示，即一个触发状态不仅对应一个或多个非周期或半持续CSI上报，还对应一种或多种码本参数，或多种参数构成的一个组合，使得UE根据编码方法确定相应的CSI上报ID和码本参数。
令M v表示频域基向量的个数；N表示窗或集合的大小；M initial表示窗的起始点。码本参数指M v、N和M initial中的一种或多种，或者这些参数的组合。网络设备给终端配置reportTriggerSize可指示Y个触发状态。
在该实施方式中，采用上述方法可以在不增加DCI开销的情况下给终端指示相应的码本参数。
在一个可行的实施方式中，网络设备和终端具体的行为及指示确定方法可以如下：
首先，网络设备通过高层信令RRC或MAC-CE给终端配置码本参数至少包括M v、N和M initial的一种或多种参数，或者配置了多种参数的组合。每种参数包含X≥1个候选值，或者候选的参数组合有X≥1个。网络设备给终端的每个CSI上报配置了S≥1触发状态，其中，同时需要满足S≥X。
然后，网络设备发送DCI中CSI请求域激活一个触发状态给终端，该触发状态不仅指示了K＝1个非周期或基于PUSCH的半持续CSI上报，还指示了上述参数中的一种或多种参数值，或者参数组合中的一个多种参数的组合。
在一个可行的实施方式中，终端可以根据触发状态和网络侧配置的候选参数或组合确定码本参数，具体示例如下。
对于Y＝X，DCI触发了Y中的第n个触发状态，则终端确定该CSI上报对应的码本参数为网络设备配置X个候选参数或组合的第n个。
对于Y>X，DCI触发了Y中的第n个触发状态,且n≤X，则终端确定该CSI上报对应的码本参数为网络设备配置X个候选参数或组合的第n个。
对于Y>X，DCI触发了Y中的第m个触发状态,且m>X，则终端确定该CSI上报对应的码本参数为网络设备配置X个候选参数或组合的第mod(X/m)个。此处仅做示例，不做限定。值得强调的是，此处的数学计算公式用于示例表示Y和X满足的一种计算关系，并不做限定，可变换地，在其他可行的实施方式中，通过简单的数学变换，还可以用其他的数学关系表示Y和X的关系，应理解，本申请实施方式中的其余计算公式也是计算关系的一种表示，并不做限定，但不论其作何变换，都在本申请实施方式保护的范围之内。
可选地，终端确定该CSI上报对应的码本参数为网络设备配置X个候选参数或组合的一个默认值，如参数或集合中的第1个。
在又一个可行的实施方式中，网络设备通过DCI中CSI请求域激活一个触发状态，该触发状态不仅指示了K>1个非周期或基于PUSCH的半持续CSI上报，还指示了上述的码本参数中所述的一种或多种参数值，或者一个多种参数的组合。K个CSI上报对应的码本参数可以依据上一个实施例确定，且这K个CSI对应的码本参数相同。
可选地，K个CSI上报对应不同的码本参数。具体地，终端确定第一个CSI上报对应的码本参数为X个中的第n个参数值或集合，终端确定第k个CSI上报对应的码本参数为X个中的第n+k个参数值或集合。若n+k>X，终端确定第k个CSI上报对应的码本参数为X个中的第mod(n+k,X)个参数值或集合,其中mod(n+k,X)表示取余操作。
进一步地，终端利用上述的方法确定的码本参数，结合与CSI上报相关联的测量信道的CSI-RS资源所估计的下行信道，计算CSI反馈信息并上报给网络设备。
下面，介绍网络设备采用上述的方式为终端配置码本参数后，向终端发 送触发状态，便于终端确定上报方式及上报的码本参数的具体实例。
实施例1：
本实施例主要描述K＝1个非周期或基于PUSCH的半持续CSI上报，触发状态与一种码本参数联合编码指示的情况。
基站给UE配置多个CSI上报信息，并且每个触发状态对应一个CSI上报。该信息中包含了码本参数M v，N和M initial。其中包含了一组X＝4个参数值，分别为0，N3/4,N3/2,N3。基站还通过RRC信令给UE配置了reportTriggerSize为3。则DCI域的大小为3bits，可以指示7个触发状态，其中触发状态0作为保留。其中码本参数与码本参数M initial的联合编码指示如下表1所示。
例如，基站向UE发送携带触发非周期SRS传输的DCI，该DCI域的值为2，则激活一个触发状态为2的非周期CSI上报，并且该CSI上报对应的M initial码本参数为N3/4。

表1中，n/a表示未能确定相应的码本参数，根据表1可知，终端根据该DCI信息确定了CSI上报的ID和码本参数M initial的值，在根据网络设备配置的其它参数如M v、N等和与该CSI上报相关联的CSI-RS资源所测量的信道信息，计算CRI/RI/CQI等其它反馈信息上报给网络设备。
实施例2：
本实施例主要描述K>1个非周期或基于PUSCH的半持续CSI上报，触发状态与一个码本参数集合联合编码指示的情况。
基站给UE的配置了多个CSI上报信息，并且每个触发状态对应一个CSI上报。CSI信息中包含了X＝4个由码本参数M v，N和M initial构成的集合，分别为{1,4,0}，{2,4,N3/4},{3,4,N3/2},{4,4,N3}。基站还通过RRC信令给UE配置了reportTriggerSize为3。则DCI域的大小为3bits，可以指示7个触发状态，其中触发状态0作为保留。其中，码本参数与码本参数{M v，N，M initial}集合的联合编码指示如下表2所示。
例如，基站向UE发送携带触发非周期SRS传输的DCI，该DCI域的值为3，则激活一个触发状态为2的非周期CSI上报，并且该CSI上报对应的码本参数集合为{3,4,N3/2}。
表2：码本参数与码本参数M initial的联合编码指示
触发状态 码本参数{M v，N，M initial}集合

根据上述表2客户自，终端利用该DCI信息确定了CSI上报的ID和码本参数M v＝3，N＝4，M initial＝N3/2，在根据网络设备配置的其它参数和该CSI上报相关联的CSI-RS资源所测量的信道信息，计算CRI/RI/CQI等其它反馈信息上报给网络侧。特别地，如果DCI域的值m＝5，则该CSI上报对应的码本参数集合为m-X＝1，即集合{1,4,0}。
UE的处理行为如上所述，此处，不做赘述。
实施例3：
本实施例主要描述K>1个非周期或基于PUSCH的半持续CSI上报的情况。
基站给UE的配置了多个CSI上报信息，并且每个触发状态对应K＝2个CSI上报。CSI信息中包含了码本参数M v，N和M initial。其中包含了一组X＝4 个参数值，分别为0，N3/4,N3/2,N3。基站还通过RRC信令给UE配置了reportTriggerSize为3。则DCI域的大小为3bits，可以指示7个触发状态，其中触发状态0作为保留。其中，码本参数与码本参数M initial的联合编码指示如下表3所示。
例如，基站向UE发送携带触发非周期SRS传输的DCI，该DCI域的值为2，则激活一个触发状态为2的非周期CSI上报，并且这两个CSI上报对应的M initial码本参数均为N3/4。

7 n/a
根据表3可知，第一个CSI上报对应的码本参数M initial为N3/4，第二个CSI上报对应的码本参数M initial为N3/2,即触发状态为n+1＝3对应的码本参数值。终端利用该DCI信息确定了这两个CSI上报对应的ID和码本参数M initial的值，在根据网络设备配置的其它参数如M v、N等和与这两个CSI上报相关联的CSI-RS资源所测量的信道信息，计算他们对应的CRI/RI/CQI等其它反馈信息上报给网络侧。
在该实施方式中，DCI请求域指示的触发状态既指示了哪个或哪些非周期或半持续基于PUSCH的CSI上报,还指示了端口选择码本的一种或多种码本参数，或者多种参数构成的一个组合，使得DCI负载的大小不改变。
在上述的方法中，提供了网络设备发送DCI中CSI请求域激活一个触发状态，该触发状态不仅指示了K＝1个非周期或基于PUSCH的半持续CSI上报，还指示了码本参数中的一种或多种参数值，或者一个多种参数的组合。根据网络设备给终端配置reportTriggerSize可指示Y个触发状态与参数或组 合的个数X之间的关系，确定指示码本参数值或集合的方法。
或者，网络设备通过DCI中CSI请求域激活一个触发状态，该触发状态不仅指示了K>1个非周期或基于PUSCH的半持续CSI上报，还指示了码本参数中的一种或多种参数值，或者一个多种参数的组合。K个CSI上报对应的码本参数可依据上述方法确定，此处不做赘述，且这K个CSI对应的码本参数相同。
进一步由终端确定K>1个CSI上报对应不同的码本参数值或集合的方法。可以不改变DCI信令大小的情况下实现码本参数的灵活指示。
可选的，终端向网络设备发送频域基向量信息之前，上述方法还包括：
基于频域基向量信息确定目标比特信息，目标比特信息用于指示频域基向量的数量和/或频域基向量对应的指示信息，其中，频域基向量对应的指示信息用于指示终端从频域基向量集合中选择频域基向量的选择方式；
终端向网络设备发送频域基向量信息，包括：
终端向网络设备发送由所述目标比特信息指示的所述频域基向量信息。
在该实施方式中，目标比特信息的形式可以是[log 2(N)]bits，换言之，终端可以通过上报[log 2(N)]bits指示所有传输层使用的频域基向量的个数M v。其中，N的取值为频域基向量的数量。例如，当频域基向量的数量为4时，N为4，则需要用2bits指示所有传输层使用的频域基向量的个数M v。在一个可行的实施方式中，可以采用二进制进行表示，例如“00”、“01”、“10”、“11”。
在一个示例中，终端还可以通过一个单独的CSI上报1bit指示所有传输层采用的是网络设备给终端配置的M v，还是终端上报的M v。
在一些可行的实施方式中，终端还可以在部分的上报结构中上报上述的目标指示内容。
可选地，终端的上报结构包括两部分上报结构或者三部分上报结构；
在终端的上报结构包括两部分上报结构的情况下，终端向网络设备发送目标指示内容，包括：
终端通过第一目标部分上报结构向网络设备发送目标指示内容；第一目标部分上报结构为两部分上报结构中的第一部分上报结构；
在终端的上报结构包括三部分上报结构的情况下，终端向网络设备发送目标指示内容，包括：
终端通过第二目标部分上报结构向网络设备发送目标指示内容；第二目标部分上报结构为三部分上报结构中的第一部分上报结构。
需要说明的是，针对Rel-17端口选择码本参数M v。M v的指示上报可为Part1和Part2两部上报，或者分为Part 0、Part1和Part2三部分上报。
具体地，分为Part1和Part2两部分上报时，Part1中的上报内容至少包含下列参数中的一种或多种：RI、宽带CQI、各子带CQI、所有层总的非零系数个数K NZ、终端选择的频域基向量个数、端口选择指示、选择的端口个数。Part2中的上报内容至少包含下列参数的一种或多种：每层的最强系数指示SCI、频域基向量指示、参考幅度、非零系数、非零系数位置指示、端口选择指示。
分为Part 0、Part1和Part2三部分上报时，Part0中的上报内容指示在Part1中上报的M v是网络侧配置的值还是终端上报的值。其中，Part1中的上报内容至少包含下列参数中的一种或多种：RI、宽带CQI、各子带CQI、所有层总的非零系数个数K NZ、终端选择的频域基向量个数、端口选择指示、选择的端口个数。Part2中的上报内容至少包含下列参数的一种或多种：每层的最强系数指示SCI、频域基向量指示、参考幅度、非零系数、非零系数位置指示、端口选择指示。
换言之，在采用Part1和Part2两部分上报时，可以在Part1中指示采用的是网络设备给终端配置的M v，还是终端上报的M v，在采用Part 0、Part1和Part2三部分上报时，可以在Part0中指示采用的是网络设备给终端配置的M v.此处仅做示例，不做限定。这样，可以通过目标指示内容快速确定，上报的M v是由网络设备配置，还是由终端根据估计的下行信道确定。
可选的，每一层传输层的频域基向量信息相同或者不同；
在每一层传输层的频域基向量信息不同的情况下，终端向网络设备发送频域基向量信息，包括：
终端向网络侧发送Z个频域基向量信息，Z为正整数，Z用于表示传输层的层数。
在该实施方式中，描述了M v的选择为layer-common和layer-specific两种情况的M v指示上报方法。其中，Layer-common表示用一个M v指示信息指示L层采用的M v；Layer-specific表示用一个M l,v指示信息指示第l层采用的M l,v，需要上报L个M v指示信息以指示L个层采用M v。换言之，Layer-common表示每一层的M v值均相同，Layer-specific表示每一层的M v值可以相同，也可以不同，在上报的过程中，针对每一层传输层发送一个频域基向量信息。例如，当有两层传输层时，选择为Layer-common时，若M v值为4，则该两层传输层的M v值均为4，选择为Layer-specific时，可以是该两层传输层的M v值均为4，也可以是第一层传输层的M v值为2，第二层传输层的M v值为4。此处仅做示例，不做限定。更具体地，每一层频域基向量信息都对应有一个目标指示内容，通过该目标指示内容可以表示各层传输层的频域基向量信息是网络侧配置的频域基向量集合种的或是预设频域基向量。
下面，分别从频域基向量的数量K＝1或者K>1时，示例说明终端上报M v值的具体步骤。
当K＝1时，即N＝N 1。
若M v的选择为layer-common，在Part1中通过上报[log 2(N)]bits指示所有传输层使用的频域基向量的个数M v。
在一个示例中，网络设备给终端配置了参数M v>1,在Part1中通过上报1bit指示所有传输层采用M v＝1，还是采用网络设备给终端配置的M v值。
在另一个示例中，网络设备给终端配置了参数M v＝1,CSI上报分为Part0、Part1和Part2三部分上报。在Part0中或者通过一个单独的CSI上报1bit指示所有传输层采用的是网络设备给终端配置M v＝1，还是终端根据估计的下行信道信息确定并上报的M v。若为终端上报的M v，则需要在Part1中上报通过上报[log 2(N)]bits指示所有传输层使用的频域基向量的个数M v。
若M v的选择为layer-specific，在Part1中通过上报
Figure PCTCN2022081482-appb-000004
bits分别指示L个传输层中第l层使用的频域基向量的个数M l,v。
在一个示例中，网络侧给终端侧配置了一个参数M v>1或者多个M l,v>1。在Part1中通过上报L bits指示第l个传输层的M l,v值为1或是网络侧给终端侧配置M l,v。
在一个示例中，网络侧给终端侧配置了参数M v＝1,CSI上报分为Part0、Part1和Part2三部分上报。在Part0中通过一个单独的CSI上报Lbits指示一个传输层采用的是网络设备给终端配置M l,v＝1，还是终端上报的M l,v。若为终端上报的M l,v，则需要再Part1中上报通过上报[log 2(N)]bits指示第l个传输层使用的频域基向量的个数M l,v。
上述的一个单独的CSI上报可以是通过一个不包含PMI的CSI reporting setting上报。在此后的PMI计算中，均采用终端上报的Mv值。
当K>1时，若M v的选择为layer-common，在Part1中通过上报K×[log 2(N)]bits指示所有传输层在每个窗/集合中使用的频域基向量的个数M v≤min(N k)。min(N k)，k＝1,…,K表示K个窗/集合中最小的值。
若M v的选择为layer-specific，在Part1中通过上报
Figure PCTCN2022081482-appb-000005
bits分别指示L个传输层中第l层在每个窗/集合中使用的频域基向量的个数M l,v。
对于每个窗或集合内的M v上报指示方法也可以采用K＝1时所述的指示上报方法。
下面，结合具体的传输层，示例说明终端上报M v值的具体步骤。
实施例1：
该实施例主要描述传输层数L＝2，K＝1，网络设备配置的窗/集合内的频域基向量个数N 1＝4的情况。
若M v的选择为layer-common，网络设备没有配置参数M v。在Part1中上报[log 2(N)]＝2bits指示终端选择的M v＝2个频域基向量。
在一示例中，网络设备给终端侧配置了参数M v＝2，在Part1中通过上报1bit指示所有传输层的M v的值，如果该bit的值为0，所有传输层采用的M v＝1。否则，所有传输层采用的M v＝2。
可选地，假设网络设备给终端配置了参数M v＝1,CSI上报分为Part0、Part1和Part2三部分。在Part0中上报1bit指示，如果该bit的值为0，那么所有传输层采用M v＝1。否则,所有传输层采用的是终端上报的M v＝2。然后在Part1中上报通过上报[log 2(N)]＝2bits指示所有传输层使用了M v＝2频域基向量。
若M v的选择为layer-specific，在Part1中通过上报L×[log 2(N)]＝4bits分 别指示第1层和第2层使用的频域基向量的个数M 1,v＝2和M 2,v＝1。
在一示例中，网络设备给终端配置了参数M 1,v＝4,M 2,v＝2，在Part1中通过上报L＝2bit指示第l个传输层的M 1,v的值，如果两个bits中的值均为0，则两个层采用的M l,v＝1,l＝1,2。否则，两个传输层采用的M 1,,v＝4,M 2,v＝2。
在一示例中，网络设备给终端配置了参数M v＝1,CSI上报分为Part0、Part1和Part2三部分。在Part0中上报L bits指示，如果两个bits中的值均为0，则两个层采用的M l,v＝1,l＝1,2。否则,两层采用的是终端上报的M 1,,v＝2,M 2,v＝1,并在Part1中上报通过上报L*[log 2(N)]＝4bits进行指示。
实施例2：
本实施例主要描述传输层L＝2，K>1,网络侧配置的两个窗/集合内的频域基向量个数N 1＝N 2＝4时M v值的指示。
若M v的选择为layer-common，网络设备没有配置参数M v。在Part1中上报K×[log 2(N)]＝4bits指示终端选择的M v＝2个频域基向量。
若M v的选择为layer-specific，在Part1中通过上报L×K×[log 2(N)]＝8bits分别指示L个传输层中第1层和第2层在每个窗/集合中使用的频域基向量的个数M 1,v＝2，M 2,v＝1。
