技术领域
本公开涉及通信领域，例如，涉及一种确定预编码的方法、装置、电子装置及存储介质。
背景技术
在无线通信技术的多天线技术中，通过给发射天线施加预编码(Precoding)，以提高通信的性能。通常，发射侧在一个资源(Resource)上，发射一个参考信号(Reference Signal，RS)，接收侧利用参考信号测量信道状态(Channel State Information，CSI)，再反馈预编码信息。预编码通常以预编码矩阵指示(Precoding Matrix Indicator，PMI)信息的方式反馈。预编码通常有预定义的形式，预编码由其包含的参数确定，反馈预编码或预编码矩阵指示信息往往又以反馈预编码参数信息的方式反馈。发射参考信号的资源是定义在频率域与时间域上的资源，是一组时频资源单元的组合。
相关技术中接收侧通过测量发射在一个资源上的参考信号，获得预编码的全部信息；但是存在以下不足：当在单个资源上传输的参考信号的天线端口数目比实际使用的天线端口数目少，或比反馈报告中要求的天线端口数目少，就不能测得预编码。
针对相关技术中接收侧获取的预编码信息存在不完整可能性的问题，目前还没有有效的解决方案。

实施例二
本公开为克服相关技术中存在的单个资源上传输的参考信号的天线端口数目比实际使用的天线端口数目少而不能测量预编码的问题，提供一种预编码的测量方法与装置(系统)。
图3是根据本公开实施例的第一通信节点确定预编码的方法流程图，如图3所示，该流程包括以下步骤：
步骤302，第一通信节点确定配置信息；
步骤304，第一通信节点传输配置信息。
本公开实施例公开了一种测量预编码的方法，包括，第一通信节点为第二通信节点确定一个或多个配置信息，第一通信节点把配置信息传输给第二通信节点；配置信息包括以下内容：大于或等于M个资源(Resource)的配置信息，反馈报告中的预编码配置信息；
其中，M是大于1的整数，所述M个Resource位于同一资源环境(Resource Settings)中；所述预编码是基于对所述M个Resource的组合测量获得的预编码；
其中，“第一”与“第二”没有顺序区别，仅用于区别两个不同的节点。
在一实施例中，通信中为了获得信道状态，通常安排在资源(Resource)上测量信号，资源是定义在频域与时域上的资源。为了方便配置资源，资源以一定的层次结构组织起来，大于或等于1个资源组成一个资源集合(Resource Set)，大于或等1个资源集合组成一个资源环境(Resource Settings)；同一个资源环境上的Resource属于同一种类型，用于传输或测量同一类型信号。预编码也是信道状态的一部分。
例如，Resource的类型是以下类型之一：信道状态信息干扰测量资源 (Channel State Information-Interference Measurement Resource，CSI-IM resource)，用于信道状态信息的干扰测量的资源。信道状态信息参考信号资源(Channel State Information-Reference Signal resource，CSI-RS resource)，用于信道状态信息参考信号的资源。同步信号与物理广播信道块资源(Synchronisation Signal/Physical broadcast channel Resource blocks，SS/PBCH resource)，用于同步信号与物理广播信道块的资源。
例如，Resource的类型是以下类型之一：信道状信息干扰测量资源(CSI-IM resource)，用于信道状态信息的干扰测量的资源。非零功率信道状态信息参考信号资源(Non-zero power Channel State Information-Reference Signal resource，Non-zero power CSI-RS resource)，用于非零功率信道状态信息参考信号的资源。零功率信道状态信息参考信号资源(zero power Channel State Information-Reference Signal resource，zero power CSI-RS resource)，用于零功率信道状态信息参考信号的资源。同步信号与物理广播信道块资源(SS/PBSCH resource)，用于同步信号与物理广播信道块的资源。
例如，Resource的类型是以下类型之一：信道状信息干扰测量资源(CSI-IM resource)，用于信道状态信息的干扰测量的资源。用于信道测量的非零功率信道状态信息参考信号资源(Non-zero power CSI-RS resource)，用于信道测量的非零功率信道状态信息参考信号的资源。用于干扰测量的非零功率信道状态信息参考信号资源(Non-zero power CSI-RS resource)，用于干扰测量的非零功率信道状态信息参考信号的资源。同步信号与物理广播信道块资源(SS/PBSCH resource)，用于同步信号与物理广播信道块的资源。
基于多个Resource的组合测量获得预编码说明如下：预编码中包含多个参数，例如一部分参数使用一个Resource测量，而另一部分参数使用另一个Resource测量，或者例如其中一部分参数要多个Resource联合测量。

Figure PCTCN2019073870-appb-000003
Figure PCTCN2019073870-appb-000004
也就是W l,m,n这个预编码由三个参数{l,m,n}决定，这个预编码可以通过对多个Resource的组合测量得到，方法可以是如下之一：l由第一个Resource测量，m由第二个Resource测量，n由第三个Resource测量；l,n由第一个Resource测量，m由由第二个Resource测量；l由第一个Resource测量，m,n由由第二个Resource测量；l,m由第一个Resource测量，n由第二个Resource测量。

Figure PCTCN2019073870-appb-000008
Figure PCTCN2019073870-appb-000009
也就是W l,m,n,p由4个参数{l,m,n,p}决定，这个预编码可以通过对多个Resource的组合测量得到，方法可以是如下之一：l由第一个Resource测量，m由第二个Resource测量，n由第三个Resource测量，p由第四个Resource测量；l,n由第一个Resource测量，m由第二个Resource测量，p由第三个Resource测量；l,m,n由第一个Resource测量，p由第一个Resource与第二个Resource联合测量；l,m由第一个Resource测量，n与p由第一个Resource与第二个Resource联合测量。

再例如，信令指示采用以下反馈类型之一：反馈基于对M个Resource的组合测量获得的预编码；反馈基于对1个Resource的测量获得的预编码；不反馈预编码。
反馈的内容来源于测量，测量的结果用于反馈，所以也可以通过信令指示测量的类型，从而指示反馈的类型。
在一实施例中，第一通信节点配置一个信令，以指示以下至少之一：用于反馈预编码信息而测量的Resource的数目；用于反馈预编码信息而测量的Resource的索引号。
举例如下：指示Resource的数目，可以是一个大于等于零的整数；例如1；例如2；例如N，其中N为一个大于等于零的整数。也可以是一个范围；例如单个，例如多个；例如大于N，其中N为一个大于等于零的整数。
再举例如下：Resource的索引号即可以是第一通信节点为其所配置的识别号，也可以是在配置队列中的秩序号。
反馈的内容来源于测量，测量的结果用于反馈，所以也可以通过信令指示测量的类型，从而指示反馈的类型。
在一实施例中，预编码信息包含第一维度预编码信息，第二维度预编码信息；其中，第一维度预编码信息从第一个Resource获得，第二维度预编码信息从第二个Resource获得；其中第一维度与第二维度仅是为了描述两个不同的维度，没有先后关系；其中第一个Resource与第二个Resource仅是为了描述两个不同的Resource，没有先后关系。
