Description

一种信息反馈的方法、装置和存储介质
相关申请的交叉引用
本申请基于申请号为201711227648.2、申请日为2017年11月29日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以引入方式并入本申请。
技术领域
本申请涉及但不限于无线通信技术，具体一种信息反馈的方法、装置和存储介质。
背景技术
无线通信中，在信道互易性存在的情况下，终端无需反馈预编码指示信息，只需反馈秩指示和信道质量指示即可；而预编码可以通过互易性利用基于上行探测导频信道探测参考信号测量到的上行信道来互易获取下行的预编码，这种方式被称为非预编码矩阵指示反馈(Non-PMI based feedback)，可以节约大量的反馈开销，尤其是对于子带反馈的开销。由于终端仍然需要计算秩指示和信道质量指示，因此，还是需要使用一种传输假设来进行计算。
第五代移动通信系统空口中，基站发送信道状态信息参考信号时，已经进行了一些预编码处理；在反馈时，一般可以基于端口选择假设(或者体现为端口选择的码字)来计算秩指示和信道质量指示；比如，一个8端口的信道状态信息参考信号，采用Non-PMI based feedback，其传输不同传输层(Rank)时，对应使用的端口(port)可以参照表1所示：
Rank 1 Rank 2 …… Rank 8
选择port i 选择port j，k …… 选择port 1-8
表1
为了获得足够的灵活性，这里port i、j、k等都是可以通过基站在8个端口中配置选择；即基站可以对端口进行配置，通知哪些端口是选择的，哪些端口是被限制的；对于端口选择和限制，简单的方式包括采用位图文件(bitmap)的方式实现端口的选择和限制，表2为采用位图文件(bitmap)的方式实现端口的选择和限制的示意，如表2所示：
  端口1 端口2 端口3 端口4 端口5 端口6 端口7 端口8
Rank 1 0 0 0 0 1 0 0 0
Rank 2 1 0 0 0 0 0 1 0
Rank 3 1 0 1 0 0 1 0 0
Rank 4 1 1 0 1 0 1 0 0
Rank 5 1 1 1 1 0 0 1 0
Rank 6 1 1 0 1 1 1 0 1
Rank 7 1 1 0 1 1 1 1 1
Rank 8 1 1 1 1 1 1 1 1
表2
表2使用了64个比特(bit)进行通知，虽然bitmap的方式看起来比较灵活，但是实际上当有多个传输块时，传输块如何映射到传输层/端口上只能使用预定义的规则；表3为预定义规则的示意：
  CW1 CW2
Rank 5 索引号较小的3个端口 索引号较大的2个端口
Rank 6 索引号较小的3个端口 索引号较大的3个端口
Rank 7 索引号较小的4个端口 索引号较大的3个端口
Rank 8 索引号较小的4个端口 索引号较大的8个端口
表3
预定义规则的方式不能保证把传输块映射到性能相近的端口(对应传输层)，这种方式可能会造成同一传输块在性能差异较大的端口/层上传输，降低传输效率。
