Description

数据处理方法及装置 技术领域
本申请涉及但不限于通信领域，具体而言，涉及一种数据处理方法及装置。
背景技术
随着科技的发展，多输入多输出(Multiple Input Multiple Output，MIMO)技术成为现代通信技术中提高频谱利用率和提供高速数据业务的重要手段之一。第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)Rel-13正在研究基于更多天线的MIMO传输技术以及相应的数据解调参考信号(Demodulation Reference Signal，DMRS)增强方案。随着天线数的增多，发送端(例如，可以是基站，下面以基站为例进行说明)可以提供更多更窄的发送波束，而由于成本等问题，接收端(例如，可以是终端，下面以终端为例进行说明)的接收天线数并没有随着成倍增加，此时还要兼顾新基站服务于旧终端，从而为了充分发挥基站端的多天线系统吞吐量，需要考虑更多用户参与的多用户多入多出(Multi-User Multiple-Input Multiple-Output，MU-MIMO)。
目前3GPP无线接入网(Radio Access Network，RAN1)82b次会议已经决定采用正交码为4的DMRS端口用于高级MU-MIMO通信，即可以采用长期演进(Long-Term Evolution，LTE)的DMRS{7,8,11,13}端口用于支持高阶MU-MIMO传输，此时接收端(可以是终端)接收到其自身的端口和层数后，无法确认其他的接收端(如，MU-MIMO用户终端)的端口占用情况，从而会造成终端进行正交掩码(Orthogonal Cover Code，OCC)长度盲检复杂度高、终端的信道估计性能低以及终端的解调接收性能低的问题。
针对相关技术中存在的由于接收端无法确认其他的接收端的端口占用情况而造成的OCC长度盲检复杂度高、接收端的信道估计性能低以及接收端的解调接收性能低的问题，目前尚未提出有效的解决方案。

下面结合具体的步骤对如何确定其他MU-MIMO用户(对应于上述的一个或多个第二接收端)占用的DMRS端口的范围进行说明：
步骤一：第一接收端根据当前使用的联合编码表格，第一接收端的PDSCH对应的层数，第一接收端对应的码字数得到一个或多个第二接收端占用的DMRS端口组。
可选地，当第一接收端使用的是联合编码表格1、第一接收端的PDSCH对应的码字数为1且第一接收端的PDSCH对应的层数小于等于X11时，一个或多个第二接收端占用的DMRS端口组为第一DMRS端口组，在本实施例中参照表3所述的联合编码表格1对应的第一DMRS端口组为{7,8}端口组；
当第一接收端使用的是联合编码表格1、第一接收端的PDSCH对应的码字数为2且第一接收端的PDSCH对应的层数小于等于X12时，一个或多个第二接收端占用的DMRS端口组为第一DMRS端口组，在本实施例中参照表3所述联合编码表格1对应的第一DMRS端口组为{7,8}端口组；
当第一接收端使用的是联合编码表格2、第一接收端的PDSCH对应的码 字数为1且第一接收端的PDSCH对应的层数小于等于X21时，一个或多个第二接收端占用的DMRS端口组为第三DMRS端口组或者第四DMRS端口组；在本实施例中参照表3所述联合编码表格2对应的第三DMRS端口组为{7,8}端口组，联合编码表格2对应的第四DMRS端口组为{7,8,11,13}端口组；
当第一接收端使用的是联合编码表格2、第一接收端的PDSCH对应的码字数为2、第一接收端的PDSCH对应的层数小于等于X22且第一个接收端的所有DMRS端口是第三或者第四DMRS端口组的一个子集时，一个或多个第二接收端占用的DMRS端口组为第三DMRS端口组或者第三DMRS端口组，在本实施例中参照表3所述联合编码表格2对应的第三DMRS端口组为{7,8}端口组，联合编码表格2对应的第四DMRS端口组为{7,8,11,13}端口组；
当为其他情况，上述一个或多个第二接收端占用的DMRS端口组为空集。
其中，X11是联合编码表格1中单码字传输中有可能是MU传输模式的最大层数，X12是所述联合编码表格1中双码字传输中有可能是MU传输模式的最大层数，其中X21是联合编码表格2中单码字传输中有可能是MU传输模式的最大层数，X22是联合编码表格2中双码字传输中有可能是MU传输模式的最大层数，本实施例中X11＝X21＝1，X12＝X22＝2；
比如，当上述的联合编码表格2使能时(即发送端指示所述第一接收端，此时依照表格2，根据联合编码域的值，得到所述第一接收端的PDSCH的层数，第一接收端的DMRS端口，第一接收端的DMRS端口的扰码标识ID：nscid)，第一接收端得到其码字数为2，联合编码值为0，此时层数为2，第一接收端的DMRS端口为{7,8}，则上述一个或多个第二接收端占用的DMRS端口组为{7,8}或者{7,8,11,13}。
步骤二：上述第一接收端根据一个或多个第二接收端占用的DMRS端口组确定一个或多个第二接收端占用的DMRS端口组范围。
可选地，上述一个或多个第二接收端占用的DMRS端口范围包括以下的一种或者两种：
第一种，DMRS端口组中的所有端口(即一个或多个第二接收端所占用的DMRS端口组中的所有端口，可能是第一DMRS端口组的所有端口，也可能是其他DMRS端口组的所有端口)，此时一个或多个第二接收端占用的DMRS端口的扰码序列的初始化参数和第一接收端的扰码序列初始化参数满足如下条件：
nscid,2＝1-nscid,1，
Figure PCTCN2016095726-appb-000016

其中nscid,1，

ns,1依次是所述第一接收端的DMRS端口对应的扰码标识ID，虚拟小区标识ID，子帧号；nscid,2，
Figure PCTCN2016095726-appb-000018
ns,2依次是一个或多个第二接收端的DMRS端口对应的扰码标识ID，虚拟小区标识ID，子帧号。
第二种，上述DMRS端口组中和第一接收端的DMRS端口号不同的端口，此时该一个或多个第二接收端占用的端口和第一接收端的DMRS端口的扰码序列相同，正交码不同；
比如，如上述步骤一所述，第一接收端的DMRS端口为{7,8}，则一个或多个第二接收端占用的DMRS端口组为{7,8}或者{7,8,11,13}。此时上述一个或者第二接收端占用的DMRS端口范围包括以下一种或者两种：
第一种，一个或多个第二接收端占用DMRS端口{7,8}或者{7,8,11,13}，此时这些端口对应的扰码序列和所述第一接收端的{7,8}端口的扰码序列不同，而且扰码序列的初始化参数满足如下条件：nscid,2＝1-nscid,1，
Figure PCTCN2016095726-appb-000019
ns,1＝ns,2。现有LTE 211协议中DMRS的初始化函数为：

则一个或多个第二DMRS端口对应的参数

下面简称此时的DMRS端口组{7,8}为伪正交DMRS端口组1，此时的DMRS端口组{7,8,11,13}为伪正交DMRS端口组2。
第二种，上述一个或多个第二接收端占用端口{}或者{11,13}，此时该 一个或多个第二接收端占用的端口和第一接收端的DMRS端口的扰码序列相同，正交码不同。下面简称此时的{}为正交DMRS端口组1，此时的{11,13}简称为正交DMRS端口组2。
本实施例的一种实施方式中，一个或多个第二接收端占用的DMRS端口范围包括两个DMRS端口组为上述伪正交DMRS端口组1或者伪正交DMRS端口组2之一和正交DMRS端口组1或者正交DMRS端口组2之一。
步骤三：第一接收端需要假设可能有一个或多个第二接收端占用上述伪正交DMRS端口组1和伪正交DMRS端口组2之一中的部分或者全部DMRS端口，该第一接收端需要进一步假设可能有一个或多个第二接收端占用上述正交DMRS端口组1和正交DMRS端口组2之一中的部分或者全部DMRS端口。当然，如上述实施例所述，当为表格1时只有伪正交组1和正交组1，此时所述第一接收端需要假设可能有一个或多个第二接收端占用上述伪正交DMRS端口组1中的部分或者全部DMRS端口，第一接收端需要进一步假设可能有一个或多个第二接收端占用上述正交DMRS端口组1中的部分或者全部DMRS端口。
