具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一 致的装置和方法的例子。
在本申请使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也是旨在包括多数形式，除非上下文清楚地表示其它含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本申请可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，例如，在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
需要说明的是，本申请所涉及的信息(包括但不限于用户设备信息、用户个人信息等)、数据(包括但不限于用于分析的数据、存储的数据、展示的数据等)以及信号，均为经用户授权或者经过各方充分授权的，且相关数据的收集、使用和处理需要遵守相关国家和地区的相关法律法规和标准。
首先对本申请实施例提供的若干个术语进行简介。
上报频域基向量：网络设备可以为终端提供服务，并且网络设备可以为终端配置CSI(Channel State Information，信道状态信息)测量配置，终端可以基于CSI测量配置进行CSI测量，向网络设备上报CSI测量报告。其中CSI测量上报包含预编码矩阵(Precoding Matrix Indicator，PMI)上报，而PMI包含频域基向量的选择。网络设备为终端配置需要上报的频域基向量(即上报频域基向量)的数量M，那么终端需要上报给基站从系统带宽包含的频域单元中选择了哪M个频域单元作为频域基向量，即上报M个频域基向量的位置。
频域窗口：当系统带宽包含的频域单元的数量大于19时，为了减少信令开销，需要终端从频域窗口内选择出M个频域基向量并告知网络设备。而频域窗口的长度则为需要上报的频域基向量M的2倍，即频域窗口长度为2M。即终端需要从2M个频域单元中选择出M个频域单元并告知基站M个频域单元的位置。
其中，该CSI测量报告包括频域基向量的选择。首先，网络设备为终端配置上报频域基向量的数量M，那当系统带宽包含的频域基向量数量大于19时，需要从频域窗口中选择出M个频域基向量，便于减少上报开销。而频域窗口的 长度为包括2M个频域基向量。并且，该频域窗口的窗口起始位置的候选位置为{-2M+1，-2M+2，……0}，0即最后一个频域基向量，-1即为倒数第二个频域基向量，以此类推，而窗口起始位置相当于选择的第一个频域基向量，那么需要继续指示从2M-1个频域基向量中选出M-1个频域基向量作为频域基向量。
在一些实施例中，频域基向量还可以成为频域单元，本申请实施例做限定。
例如，图1中终端在上报确定的频域基向量时，会从图1中包括的24个频域基向量确定部分频域基向量，以M为4为例进行说明。窗口起始位置取值包括{-7，-6……0}，若确定取值为-6，即从最后面开始数为倒数第6个，即频域基向量19为频域窗口的起始位置，也就是确定的第一个频域基向量，因此频域窗口包括的2M个频域基向量包括频域基向量19、频域基向量20、频域基向量21、频域基向量22、频域基向量23、频域基向量24、频域基向量1和频域基向量2。终端上报时，首先指示窗口起始位置，然后再指示其它M-1个频域单元位置。
下面，对本申请的应用场景进行说明：
图2示出了本申请一个示例性实施例提供的通信系统的框图，该通信系统可以包括：终端10和网络设备20。
终端10的数量通常为多个，每一个网络设备20所管理的小区内可以分布一个或多个终端10。终端10可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端。
网络设备20是一种部署在接入网中用以为终端10提供无线通信功能的装置。为方便描述，本申请实施例中，上述为终端10提供无线通信功能的装置统称为网络设备。网络设备20与终端10之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。网络设备20的数量可以有多个，两个邻近的网络设备20之间也可以通过有线或者无线的方式进行通信。终端10可以在不同的网络设备20之间进行数据传输，也即与不同的网络设备20建立连接。
该网络设备20可以包括各种形式的宏基站、微基站、中继站、接入点等等。在采用不同的无线接入技术的系统中，具备网络设备功能的设备的名称可能会 有所不同，例如在5G NR(New Radio，新空口)系统中，称为gNodeB或者gNB。随着通信技术的演进，“网络设备”这一名称可能会变化。
可选地，网络设备20上设置有至少两个TRP(Transmission Reception Point,传输接收节点)；或者至少两个网络设备20，每个网络设备上设置至少一个TRP，即至少两个网络设备20设置有至少两个TRP。也就是说，至少两个TRP可以来自同一个小区或不同的小区。
在一些实施例中，网络设备20上设置4个TRP，并且可以通过4个TRP为终端10提供服务，并且终端10需要针对4个TRP进行CSI测量上报。
本申请实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
图3示出了本申请一个示例性实施例提供的上报数量指示方法的流程图，示例性的可以应用于如图2所示的终端和网络设备中，该方法包括以下内容中的至少部分内容：
步骤301：网络设备向终端发送配置信令，配置信令用于指示多个信道测量资源集的上报数量，多个信道测量资源集的上报数量相同，或者，多个信道测量资源集中至少两个信道测量资源集的上报数量不同，上报数量为终端针对上报数量对应的信道测量资源集上报的频域基向量的数量。
步骤302：终端接收网络设备发送的配置信令。
在本申请实施例中，网络设备与终端之间会进行通信，网络设备会为终端配置信道测量资源集，并且还会指示每个信道测量资源集的上报数量，该上报数量是指终端针对上报数量对应的测量资源集上报的频域基向量的数量，也就是说网络设备通过配置信令向终端指示了终端对于每个信道测量资源集需要上报的频域基向量的数量。并且，终端还会根据上报数量确定频域窗口的长度，进而基于频域窗口确定该频域窗口内所包括的频域基向量，进而上报从频域窗口内所包括的频域基向量中所选择的频域基向量。
其中，网络设备为终端配置多个信道测量资源集，并且多个信道测量资源集的上报数量可以相同或不同，也就是说终端针对多个信道测量资源集上报频域基向量的数量可以相同或不同。
在一些实施例中，多个信道测量资源集中的每个信道测量资源集对应一个 TRP，也就是多个信道测量资源集对应多个TRP。换一种表达方式，网络设备可以通过多个TRP为终端提供服务。
在一些实施例中，该配置信令包括上报数量对应的信道资源集标识，通过该信道资源集标识指示信道资源集使用对应的上报数量。
对于网络设备通过配置信令指示多个信道测量资源集的上报数量来说，包括以下两种情况：
第一种：多个信道测量资源集的上报数量相同。
在本申请实施例中，网络设备通过配置信令指示了一个上报数量，并且该上报数量适用于多个信道测量资源集。并且终端可以根据该上报数量确定频域窗口的长度，也就是说确定的频域窗口的长度也适用于多个信道测量资源集。
例如，多个信道测量资源集包括信道测量资源集1、信道测量资源集2、信道测量资源集3和信道测量资源集4。网络设备通过配置信令为终端配置了一个上报数量A，该上报数量A适用于信道测量资源集1、信道测量资源集2、信道测量资源集3和信道测量资源集4。
第二种：多个信道测量资源集中至少两个信道测量资源集的上报数量不同。
在本申请实施例中，网络设备通过配置信令为终端的多个信道测量资源集中的至少两个信道测量资源集配置不同的上报数量，也就是说多个信道测量资源集中存在不同的信道测量资源集使用不同的上报数量。
在一些实施例中，上报数量的个数与信道测量资源集的数量相同，或者，上报数量的个数小于信道测量资源集的数量。
其中，若上报数量的个数小于信道测量资源集的数量，说明存在多个信道测量资源集共用一个上报数量的情况，并且还存在其他信道测量资源集使用其他上报数量的情况。
例如，多个信道测量资源集包括信道测量资源集1、信道测量资源集2、信道测量资源集3和信道测量资源集4。网络设备通过配置信令为终端的信道测量资源集1、信道测量资源集2配置了一个上报数量A，为信道测量资源集3配置了一个上报数量B，为信道测量资源集4配置了一个上报数量C。
在一些实施例中，多个信道测量资源集中至少两个信道测量资源集包含不同的CSI-RS资源，或多个信道测量资源集中至少两个信道测量资源集包含同一个CSI-RS资源的不同端口组。
在本申请实施例中，一个信道测量资源集包括至少一个CSI-RS(Channel  State Information Reference Signal，信道状态信息参考信号)资源，并且至少存在两个信道测量资源集包括的CSI-RS资源不同。又或者，一个信道测量资源集包括至少一个端口组，至少存在两个信道测量资源集包括的端口组不同，并且信道测量资源集包括的所有端口组属于同一个CSI-RS资源。
在一些实施例中，该配置信令还用于指示多个传输层(layer)的上报数量，多个传输层的上报数量相同，或者多个传输层中至少两个传输层的上报数量不同。
其中，信道测量资源集与传输层具有映射关系。例如，一个信道测量资源集对应一个或多个传输层，本申请实施例不做限定。
需要说明的是，本申请实施例中若配置信息用于指示多个传输层的上报数量，若针对每个信道测量资源集，其多个传输层上需要上报的频域基向量的数量相同时，则针对所有传输层，使用本申请实施例中的方法确定每个信道测量资源集对应的一个需要上报的频域基向量的数量，并上报每个信道测量资源集对应的频域基向量的位置。若针对每个信道测量资源集，其多个传输层上需要上报的频域基向量的数量不同时，则针对每个传输层，使用本申请实施例中的方法确定每个信道测量资源集对应的一个需要上报的频域基向量的数量，并上报每个信道测量资源集对应的频域基向量的位置。
需要说明的是，本申请实施例中终端所执行的步骤可以单独形成一个新的实施例，网络设备所执行的步骤也可以单独形成一个新的实施例，本申请不做限定。
本申请提供了一种配置上报数量的方案，网络设备可以联合多个信道测量资源集为终端配置需要上报的频域基向量的数量，以便于终端根据配置的需要上报的频域基向量的数量再确定频域窗口进行频域基向量的上报，扩展了上报频域基向量的数量的配置方式，保证了传输的可靠性。
图3所示实施例对网络设备可以通过配置信令为终端指示多个信道测量资源集的上报数量进行了说明。下面，对终端如何基于已配置的上报数量确定出频域窗口长度，并采用相同的窗口起始位置向网络设备上报频域基向量进行说明。图4示出了本申请一个示例性实施例提供的窗口起始位置指示方法的流程图，示例性的可以应用于如图2所示的终端和网络设备中，该方法包括以下内容中的至少部分内容：
步骤401：终端在多个信道测量资源集的上报数量相同的情况下，针对多个信道测量资源集确定一个第一窗口起始位置，该第一窗口起始位置为频域窗口的起始位置，频域窗口内包括的频域基向量的数量为上报数量的整数倍。
在本申请实施例中，若多个信道测量资源集的上报数量相同，则说明多个信道测量资源集共用一个相同的上报数量，并且终端可以根据该上报数量确定频域窗口长度，即多个信道测量资源集对应相同的频域窗口长度，则可以针对这多个信道测量资源集确定一个第一窗口起始位置，该第一窗口起始位置为频域窗口的起始位置，并且该频域窗口的长度为基于上报数量确定的频域窗口长度，并且该频域窗口内包括的频域基向量的数量为上报数量的整数倍，另外多个信道测量资源集共用确定的一个第一窗口起始位置。也就是说，多个信道测量资源集所对应的频域窗口的窗口起始位置均为第一窗口起始位置。其中，整数倍为2倍、3倍或其他数值，本申请实施例不作限定。
例如，多个信道测量资源集包括信道测量资源集1、信道测量资源集2、信道测量资源集3和信道测量资源集4。以图1为例，4个信道测量资源集的第一窗口起始位置均为频域基向量19，或者，4个信道测量资源集的第一窗口起始位置均为频域基向量20，或者，为其他频域窗口中的其他频域基向量。
步骤402：终端向网络设备发送第一指示信息，第一指示信息用于指示第一窗口起始位置。
步骤403：网络设备接收终端发送的第一指示信息，该第一指示信息用于指示第一窗口起始位置，第一窗口起始位置由终端在多个信道测量资源集的上报数量相同的情况下，针对多个信道测量资源集确定的一个第一窗口起始位置。
在本申请实施例中，终端通过步骤401确定多个信道测量资源集共用的第一窗口起始位置后，即可向网络设备发送用于指示第一窗口起始位置的第一指示信息，网络设备接收到该第一指示信息后，即可确定多个信道测量资源集的频域窗口的第一窗口起始位置。而第一窗口起始位置即终端在窗口内选择的第一个频域基向量的位置。
在一些实施例中，在上报数量的数量为M时，则确定的频域窗口的频域窗口长度包括2M个频域基向量，因此在指示多个信道测量资源集的一个第一窗口起始位置时，需要采用的比特数为
Figure PCTCN2022109168-appb-000001
其中
Figure PCTCN2022109168-appb-000002
为向上取整。
需要说明的是，本申请实施例对多个信道测量资源集对应相同的第一窗口起始位置进行说明。而终端还需要向网络设备上报在频域窗口内，每个信道测 量资源集对应的其它频域基向量。下面，对终端上报频域基向量的多种方式进行说明。
第一种：第一指示信息还用于指示至少一组信道测量资源集的M-1个频域基向量的位置，M-1个频域基向量属于频域窗口内包括的频域基向量，且不同于第一窗口起始位置对应的频域基向量，M为上报数量，且M为正整数，每组信道测量资源集包括至少一个信道测量资源集。
在一些实施例中，M-1个频域基向量属于2M个频域基向量中除第一窗口起始位置对应的频域基向量以外的频域基向量，2M个频域基向量为以第一窗口起始位置为起点，且长度为2M的频域窗口包括的频域基向量。
在本申请实施例中，终端可以确定至少一组信道测量资源集的M-1个频域基向量的位置。也就是说终端可以将多个信道测量资源集划分为至少一组信道测量资源集，每组信道测量资源集对应M-1个频域基向量的位置。
并且，每组信道测量资源集对应的M-1个频域基向量的位置是属于2M个频域基向量中除第一窗口起始位置对应的频域基向量以外的频域基向量。也就是2M个频域基向量中除第一窗口起始位置对应的频域基向量以外的2M-1个频域基向量。
在本申请实施例中，多个信道测量资源集的上报数量相同，并且频域窗口长度为上报数量的2倍，即多个信道测量资源集对应的频域窗口长度相同，也就是说，每组信道测量资源集的频域基向量均是从相同的2M-1个频域基向量中选择的M-1个频域基向量。
其中，2M个频域基向量均是以第一窗口起始位置为起点，且长度为2M的频域窗口内所包括的频域基向量。另外，每组信道测量资源集包括至少一个信道测量资源集。
在一些实施例中，第一指示信息仅指示一组信道测量资源集对应的M-1个频域基向量的位置，则说明上述多个信道测量资源集被分为一组信道测量资源集，多个信道测量资源集共用相同的M-1个频域基向量的位置。
可选地，采用
Figure PCTCN2022109168-appb-000003
个比特指示M-1个频域基向量的位置，其中
Figure PCTCN2022109168-appb-000004
为向上取整。
在本申请实施例中，终端确定的多个信道测量资源集的频域基向量的位置相同，因此终端从2M-1个频域基向量中确定M-1个频域基向量，通过该第一指示信息指示确定的M-1个频域基向量的位置即可。也就是说，多个信道测量 资源集的频域基向量共用第一指示信息指示的M-1频域基向量。换一种表达方式，第一指示信息的M-1个频域基向量适用于多个信道测量资源集。
例如，以图1为例，M为4，终端确定的频域窗口的第一窗口起始位置为频域基向量19，并且频域窗口包括的2M个频域基向量为频域基向量19、频域基向量20、频域基向量21、频域基向量22、频域基向量23、频域基向量24、频域基向量1和频域基向量2，在除去作为窗口起始位置的频域基向量19后，终端从频域基向量20、频域基向量21、频域基向量22、频域基向量23、频域基向量24、频域基向量1和频域基向量2选择3个频域基向量即可。例如，选择的3个频域基向量为频域基向量20、频域基向量21和频域基向量22，或者为频域基向量22、频域基向量23和频域基向量1，本申请实施例不再一一举例说明。
在另一些实施例中，第一指示信息指示多组信道测量资源集的M-1个频域基向量的位置，则说明多组信道测量资源集包括的信道测量资源集为上述多个信道测量资源集，每组信道测量资源集包括的至少一个信道测量资源集共用该组信道测量资源集对应的M-1个频域基向量的位置。也可以理解为，多个信道测量资源集中至少两个信道测量资源集对应不同的M-1个频域基向量。
在本申请实施例中，终端可以针对每组信道测量资源集分别确定M-1个频域基向量，也就是终端针对多个信道测量资源集中的一个或多个信道测量资源集分别确定M-1个频域基向量，并通过第一指示信息分别指示每组信道测量资源集的M-1个频域基向量的位置。
可选地，终端确定的多组信道测量资源集的组数与多个信道测量资源集的数量相同，也就是说一个信道测量资源集为一组，可以理解为终端为多个信道测量资源集分别确定了M-1个频域基向量。或者，终端确定的多组信道测量资源集的组数小于多个信道测量资源集的数量，也就是说终端为多个信道测量资源集中的至少两个信道测量资源分别确定了不同的M-1个频域基向量。
其中，2M-1个频域基向量是指以第一窗口起始位置为起点的频域窗口内，除第一窗口起始位置对应的频域基向量以外的其他频域基向量。也就是说，终端从2M-1个频域基向量中为每组信道测量资源集选择了M-1个频域基向量。
例如，多个信道测量资源集包括信道测量资源集1、信道测量资源集2、信道测量资源集3和信道测量资源集4，而信道测量资源集1和信道测量资源集2为一组信道测量资源集，信道测量资源集3单独为一组信道测量资源集，信道 测量资源集4单独为一组信道测量资源集。
以图1为例，M为4，终端确定的频域窗口的第一窗口起始位置为频域基向量19，并且频域窗口包括的2M个频域基向量为频域基向量19、频域基向量20、频域基向量21、频域基向量22、频域基向量23、频域基向量24、频域基向量1和频域基向量2，终端信道测量资源集1和信道测量资源集2确定的M-1个频域基向量包括频域基向量20、频域基向量21和频域基向量22，为信道测量资源集3确定的M-1个频域基向量包括频域基向量22、频域基向量23和频域基向量24，为信道测量资源集4确定的M-1个频域基向量包括频域基向量23、频域基向量1和频域基向量2。
又例如，多个信道测量资源集包括信道测量资源集1、信道测量资源集2、信道测量资源集3和信道测量资源集4，终端分别为信道测量资源集1确定了M-1个频域基向量，为信道测量资源集2确定了M-1个频域基向量，为信道测量资源集3确定了M-1个频域基向量，为信道测量资源集4确定了M-1个频域基向量。
第二种：第一指示信息包括第一部分和第二部分；第一部分包括多个信道测量资源集对应的相同频域基向量的位置，第二部分包括每个信道测量资源集对应的不同频域基向量的位置。
在本申请实施例中，第一指示信息还可以指示窗口起始位置以外的其他频域基向量。对于多个信道测量资源集来说，在通过第一指示信息指示第一窗口起始位置后，还需要指示多个信道测量资源集分别对应的M-1个频域基向量，因此可以通过第一指示信息的第一部分指示多个信道测量资源集对应的相同的频域基向量，通过第二部分分别指示多个信道测量资源集中每个信道测量资源集对应的不同频域基向量的位置。
其中，每个信道测量资源集对应的不同频域基向量的位置是指除第一部分指示的相同的频域基向量以外的其他频域基向量的位置。
例如，多个信道测量资源集包括信道测量资源集1、信道测量资源集2、信道测量资源集3和信道测量资源集4，信道测量资源集1对应的频域基向量为频域基向量20、频域基向量21和频域基向量22，信道测量资源集2对应的频域基向量为频域基向量20、频域基向量21和频域基向量23，信道测量资源集3对应的频域基向量为频域基向量20、频域基向量21和频域基向量24，信道测量资源集4对应的频域基向量为频域基向量20、频域基向量21和频域基向量1。 则第一指示信息的第一部分指示N个信道测量资源集对应的相同的频域基向量为频域基向量20和频域基向量21，第二部分指示信道测量资源集1对应频域基向量22，信道测量资源集2对应频域基向量23，信道测量资源集3对应频域基向量24，信道测量资源集4对应频域基向量1。
本申请实施例提供的方案中，终端通过第一指示信息向网络设备指示多个信道测量资源集共用相同的窗口起始位置，并且还可以通过不同方式指示多个信道测量资源集对应的其他频域基向量，扩展了终端上报选择的频域基向量的多样性。并且，终端根据配置的上报数量确定频域窗口长度，并基于频域窗口长度进行频域基向量的上报，扩展了上报数量的配置方式，保证了传输的可靠性。
图3所示实施例对网络设备可以通过配置信令为终端指示多个信道测量资源集的上报数量进行了说明。下面，对终端如何基于已配置的上报数量采用不同的窗口起始位置向网络设备上报频域基向量进行说明。图5示出了本申请一个示例性实施例提供的窗口起始位置指示方法的流程图，示例性的可以应用于如图2所示的终端和网络设备中，该方法包括以下内容中的至少部分内容：
步骤501：终端针对多个信道测量资源集确定至少两个第二窗口起始位置，每个第二窗口起始位置对应至少一个信道测量资源集，该第二窗口起始位置为频域窗口的起始位置，该频域窗口内包括的频域基向量的数量为上报数量的整数倍。
在本申请实施例中，终端针对多个信道测量资源集确定至少两个第二窗口起始位置，每个第二窗口起始位置对应至少一个信道测量资源集，也就是多个信道测量资源集中至少两个信道测量资源集对应不同的第二窗口起始位置。
其中，终端可以根据配置的上报数量确定频域窗口长度，已确定的至少两个第二窗口起始位置为频域窗口的起始位置，频域窗口的长度为确定的频域窗口长度，并且该频域窗口内包括的频域基向量的数量为上报数量的整数倍。
例如，终端确定了两个第二窗口起始位置，分别为第二窗口起始位置1和第二窗口起始位置2，多个信道测量资源集包括4个信道测量资源集，分别为信道测量资源集1、信道测量资源集2、信道测量资源集3和信道测量资源集4。则可以为信道测量资源集1、信道测量资源集2和信道测量资源集3对应第二窗口起始位置1，信道测量资源集4对应第二窗口起始位置2。
步骤502：终端向网络设备发送第二指示信息，该第二指示信息用于指示多个信道测量资源集对应的至少两个第二窗口起始位置。
步骤503：网络设备接收终端发送的第二指示信息。
在本申请实施例中，终端确定至少两个第二窗口起始位置后，即可向网络设备发送第二指示信息，通过该第二指示信息指示多个信道测量资源集对应的至少两个第二窗口起始位置。
对于终端发送的第二指示信息来说，终端可以采用不同的方式来指示至少两个第二窗口起始位置，下面对每种方式进行说明。
第一种：第二指示信息用于指示至少两个第二窗口起始位置的绝对位置。
在本申请实施例中，通过该第二指示信息指示每个第二窗口起始位置的绝对位置，进而网络设备接收到该第二指示信息后，可以确定至少两个第二窗口起始位置的位置。
其中，该绝对位置是指每个第二窗口起始位置的实际位置。例如，以图1为例，在M为4的情况下，第二窗口起始位置的绝对位置的取值包括{-7，-6……0}，也就是可以采用3比特指示即可。
第二种：第二指示信息用于指示至少两个第二窗口起始位置中参考窗口起始位置的绝对位置。
在本申请实施例中，终端从确定的至少两个第二窗口起始位置中，选择一个参考窗口起始位置，通过该第二指示信息指示参考窗口起始位置的绝对位置，至少两个第二窗口起始位置中除参考窗口起始位置以外的其他第二窗口起始位置根据该参考窗口起始位置指示。
在一些实施例中，该参考窗口起始位置的绝对位置的取值包括{-7，-6……0}。
可选地，参考窗口起始位置为至少两个第二窗口起始位置中最早的起始位置。
在本申请实施例中，终端从至少两个第二窗口起始位置中，确定最早的起始位置为参考窗口起始位置，位于该参考窗口起始位置之后的其他第二窗口起始位置即可根据该参考窗口起始位置确定。比如其他第二窗口起始位置为相对应参考窗口起始位置的相对值。
可选地，第二指示信息还用于指示参考窗口起始位置对应的信道测量资源集对应的CSI-RS资源标识或资源集标识或CSI-RS资源的端口组标识。
在本申请实施例中，该第二指示信息还指示参考窗口起始位置对应的信道 测量资源集对应的CSI-RS资源标识或资源集标识或CSI-RS资源的端口组标识，则至少两个第二窗口起始位置中除参考窗口起始位置以外的其他第二窗口起始位置即可按照CSI-RS资源标识或资源集标识或CSI-RS资源的端口组标识由大到小或由小到大的顺序依次指示即可。
例如，若本申请实施例中包括4个信道测量资源集，则有4个CSI-RS资源或CSI-RS资源的端口组ID，4个CSI-RS资源或CSI-RS资源的端口组ID需要2bit指示。在M为4的情况下，00指示CSI-RS#1对应的窗口起始位置为参考窗口起始位置。
在一些实施例中，第二指示信息还用于指示除参考窗口起始位置以外的其他第二窗口起始位置，其他第二窗口起始位置为相对于参考窗口起始位置的相对位置。
在本申请实施例中，终端已通过第二指示信息指示了参考窗口起始位置，还会指示至少两个第二窗口起始位置中，除参考窗口起始位置以外其他第二窗口起始位置相对于参考窗口起始位置的相对位置。
进一步地，该第二指示信息指示参考窗口起始位置后，还会指示至少两个第二窗口起始位置中除参考窗口起始位置以外的其他第二窗口起始位置，具体的指示方式包括两种。
可选地，第二指示信息还用于指示除参考窗口起始位置以外的其他第二窗口起始位置，其他第二窗口起始位置为相对于参考窗口起始位置的相对位置。
在本申请实施例中，第二指示信息已经指示了参考窗口起始位置的绝对值，则相对于该参考窗口起始位置，指示至少两个第二窗口起始位置中除参考窗口起始位置以外的其他第二窗口起始位置。
例如，通过一定的比特数指示参考窗口起始位置的对应的信道测量资源集对应的CSI-RS资源标识或资源集标识或CSI-RS资源的端口组标识，然后接下来的比特即可依次指示其他信道测量资源集对应的第二窗口起始位置相对于参考窗口起始位置的相对值。
例如，以图1为例，在指示的参考窗口起始位置的对应的信道测量资源集对应的CSI-RS资源标识或资源集标识或CSI-RS资源的端口组标识的比特值后，接下来的比特数指示CSI-RS#0的窗口起始位置与参考窗口起始位置-7的相对值，取值可以为0～7，所以需要3bit(比特)；再接下来的比特数指示CSI-RS#2的窗口起始位置与参考窗口起始位置-7的相对值，取值可以为0～7，所以也需要 3bit.再接下来的比特数指示CSI-RS#3的窗口起始位置与参考窗口起始位置-7的相对值，取值可以为0～7，所以也需要3bit。
又例如，例如最早的参考窗口起始位置为-3，则接下来的bit数指示CSI-RS#0的窗口起始位置与参考窗口起始位置-3的相对值，取值可以为0～3，所以需要2bit；再接下来的bit数指示CSI-RS#2的窗口起始位置与参考窗口起始位置-3的相对值，取值可以为0～3，所以也需要2bit.再接下来的bit数指示CSI-RS#3的窗口起始位置与参考窗口起始位置-3的相对值，取值可以为0～3，所以也需要2bit。
可选地，第二指示信息还用于指示除参考窗口起始位置以外的其他的第二窗口起始位置，第i+1个第二窗口起始位置为相对于第i个第二窗口起始位置的相对位置，第i个第二窗口起始位置为位于第i+1个第二窗口起始位置之前，且与第i+1个第二窗口起始位置距离最近的窗口起始位置，i为正整数，i不大于N-1。
例如，通过一定的比特数指示参考窗口起始位置的对应的信道测量资源集对应的CSI-RS资源标识或资源集标识或CSI-RS资源的端口组标识，然后接下来的比特即可依次指示第i+1个第二窗口起始位置为相对于第i个第二窗口起始位置的相对位置。
例如，以图1为例，在指示的参考窗口起始位置的对应的信道测量资源集对应的CSI-RS资源标识或资源集标识或CSI-RS资源的端口组标识的比特值后，接下来的bit数指示CSI-RS#0(2bit)及其窗口起始位置与参考窗口起始位置-7的相对值，取值范围可以为0～7，所以需要3bit，比如取值为2，即窗口起始位置为-5；再接下来的bit数指示CSI-RS#2(1bit)及其窗口起始位置与-5的相对值，取值可以为0～5，所以也需要3bit，比如取值为2，即为窗口起始位置-3.再接下来的bit数指示CSI-RS#3(最后一个，不需要指示)的窗口起始位置与-3的相对值，取值可以为0～3，所以需要2bit。
又例如，最早的参考窗口起始位置为-3，则接下来的bit数指示CSI-RS#0(2bit)及其窗口起始位置与参考窗口起始位置-3的相对值，取值范围可以为0～3，所以需要2bit，比如取值为2，即窗口起始位置为-1；再接下来的bit数指示CSI-RS#2(1bit)及其窗口起始位置与-1的相对值，取值可以为0～1，所以也需要1bit，比如取值为1，即窗口起始位置为0。再接下来的bit数指示CSI-RS#3(最后一个，不需要指示)的窗口起始位置与0的相对值，取值可以为0，所以 不需要bit。
需要说明的是，本申请实施例通过第二指示信息指示多个信道测量资源集的第二窗口起始位置后，后续即可进一步根据频域窗口长度确定M-1个频域基向量并上报。
在一些实施例中，在多个信道测量资源集的上报数量相同的情况下，第二指示信息还用于指示至少一组信道测量资源集中的每组信道测量资源集分别对应的M-1个频域基向量的位置，M-1个频域基向量属于每个信道测量资源集对应的频域窗口内包括的频域基向量，且不同于每组信道测量资源集对应的第二窗口起始位置对应的频域基向量，每组信道测量资源集包括至少一个信道测量资源集，M为上报数量，M为正整数。
在一些实施例中，M-1个频域基向量属于每组信道测量资源集分别对应的2M个频域基向量中除第二窗口起始位置对应的频域基向量以外的频域基向量，第二窗口起始位置为每组信道测量资源集对应的窗口起始位置，2M个频域基向量为以第二窗口起始位置为起点，且长度为每组信道测量资源集对应的频域窗口长度的频域窗口包括的频域基向量。
其中，本申请实施例中指示M-1个频域基向量的方式与上述实施例中采用相同的第一窗口起始位置的方式类似，区别仅在于本申请实施例是存在至少两个信道测量资源集采用不同的第二窗口起始位置，也就是说仅是窗口起始位置发生了变化，选择M-1个频域基向量的方式不变。
在另一些实施例中，在多个信道测量资源集中至少两个信道测量资源集的上报数量不同的情况下，第二指示信息还用于指示至少一组信道测量资源集中的每组信道测量资源集分别对应的M-1个频域基向量的位置，M-1个频域基向量属于每个信道测量资源集对应的频域窗口内包括的频域基向量，且不同于每组信道测量资源集对应的第二窗口起始位置对应的频域基向量，每组信道测量资源集包括至少一个信道测量资源集，M为每组信道测量资源集的上报数量，M为正整数。
在一些实施例中，M-1个频域基向量属于每组信道测量资源集分别对应的2M个频域基向量中除第二窗口起始位置对应的频域基向量以外的频域基向量，第二窗口起始位置为每组信道测量资源集的窗口起始位置，2M个频域基向量为以第二窗口起始位置为起点，且长度为每组信道测量资源集对应的频域窗口长度的频域窗口包括的频域基向量。
其中，本申请实施例中指示M-1个频域基向量的方式与上述实施例中采用相同的第一窗口起始位置的方式类似，区别仅在于本申请实施例是存在至少两个信道测量资源集采用不同的第二窗口起始位置和上报数量，而频域窗口长度根据上报数量确定，也就是说仅是窗口起始位置和频域窗口长度发生了变化，选择M-1个频域基向量的方式不变。
需要说明的是，上述实施例可以拆分为新实施例，或与其他实施例互相组合为新实施例，本申请对实施例之间的组合不做限定。
