Description

用户配对处理方法、装置及基站 技术领域
本发明涉及通信领域，具体而言，涉及一种用户配对处理方法、装置及基站。
背景技术
多用户-多输入多输出(Multiple User-Multiple Input Multiple Output，简称为MU-MIMO)是一种空间分集技术，在不增加系统带宽的情况下成倍地提高通信系统的容量和频谱利用率；利用分集来减轻多径衰落的影响，并能有效地消除共道干扰，提高信道的可靠性，降低误码率，是新一代移动通信系统采用的关键技术。
MU-MIMO是让多用户使用相同的时频资源，从而进一步提高系统容量的方法和技术。由于MU-MIMO的用户要空分时频域的资源，因此如果空分相同时频域的用户之间空间正交性不是很好，那么这些空分的用户之间产生了严重的干扰，不仅不能提升空分系统的空口容量，反而增加了误码率，对于系统容量以及用户时延产生了影响，因此对于空分用户的配对选择成为了MU-MIMO系统研究的关键。
在相关技术中，MU-MIMO用户配对方法主要分为以下两类：第一类是根据预编码矩阵指示(Precoding Matrix Indicator，简称为PMI)来计算干扰及相关性，然后配对。由于PMI的数量受限于公共参考信号(Common Reference Signal，简称为CRS)端口数且对于一定的CRS端口协议规定的码本数有限，因此预编码矩阵有量化误差即与实际的信道矩阵会存在误差，这就会导致所计算出来的干扰有误差且会导致波束赋形方向不准；第二类是对信道矩阵做奇异值分解，计算零空间。需要对所有用户的信道矩阵做奇异值分解，因此当空分用户较多时计算量大、复杂度高。而且利用这种方法在选取了第一配对用户后只考虑用户之间的干扰而未考虑其他配对用户的信道质量指示(Channel Quality Indicate，简称为CQI)，所以在容量和复杂度方面都不是很优。另外，由于Massive MIMO技术的引入，使得空分用户大量增加，量化误差以及复杂度的影响更加凸显。
因此，在相关技术中对用户使用MU-MIMO进行配对时，存在干扰误差，以及配对容量小，复杂度高的问题。

步骤S108，依据生成的空分信息表确定配对用户。
通过上述步骤，通过依据接收到的SRS生成的信道矩阵H来获取用于标识UE之间相关性的空分信息表；依据生成的空分信息表确定配对用户，通过上述处理，不仅解决了相关技术中对用户使用MU-MIMO进行配对时，存在干扰误差，以及配对容量小，复杂度高的问题，进而达到了简化用户配对复杂度，以及提高MU-MIMO系统容量的效果。
其中，依据接收的所述SRS、PMI等信号生成所述UE的信道矩阵H时，依据UE支持天线的不同，可以采用不同处理方式，例如，可以取一根UE天线做H，在UE支持SRS天线轮发时，随机选取其中一根天线的信道矩阵；UE不支持SRS天线轮发 时，信道矩阵即为该天线的信道矩阵H＝SRS收/SRS发。其中，SRS收为接收端的SRS信号，SRS发为发送端的SRS信号。
在计算相关性权值之前，可以首先对信道矩阵H做归一化处理，通过Cov＝Hi’*Hj得出UE之间的相关系数，其中Hi和Hj分别为UEi和UEj的归一化信道矩阵；之后，在依据生成的H生成用于标识UE之间相关性的空分信息表时，可以采用多种处理方式，例如，可以判断UE两两之间的相关性是否小于预定阈值；在判断结果为是的情况下，确定UE之间支持配对；和/或，在判断结果为否的情况下，确定UE之间不支持配对，其中，在所述空分信息表中标识所述UE支持配对与不支持配对。即，在判断为相关时，采用一种标识来进行标注，在判断为不相关时，采用另一种标识来进行标注。
在依据生成的空分信息表确定配对用户时，也可以采用多种处理方式，例如，可采用以下优选的处理方式，先确定每个UE与之支持配对的UE的个数；之后依据与之支持配对的UE的个数对UE进行排序；按照由该个数从多到少的顺序，删除与UE不支持配对的UE直至完成用户配对。通过这样的处理，尽可能多地空分更多的用户，以提高MU-MIMO的系统容量。
需要说明的是，在依据与之支持配对的UE的个数对UE进行排序时，可能存在与之支持配对的UE的个数相同的情况，在这样的情况下，可以依据UE的用户优先级对UE进行排序。
优选地，在依据生成的空分信息表确定配对用户之前，在对用户进行配对时，为了尽可能全面地考虑可能涉及到的因素，例如，可以将各个配对因素综合考虑，例如，可以先确定UE的以下信息至少之一：服务质量QoS优先级、调制编码机制MCS信息、缓存状态报告BSR信息，依据确定的UE的上述信息至少之一以及空分信息表确定配对用户。
