摘要： A base station is capable of unifying a single-user MIMO scheme with a multi-user MIMO scheme by receiving a Rank-1 CQI values from one or more subscriber stations. The base station also receives precoding vectors from the subscriber stations, and then determines which of the subscriber stations has a best Rank-1 CQI value. The base station then determines a beam forming matrix to use based at least in part on the vectors received from the subscriber station having the best Rank-1 CQI value. The base station then broadcasts data to the subscriber station using the beam forming matrix corresponding to the subscriber station having the best Rank-1 channel quality indicator to implement single-user MIMO in one or multiple streams to that subscriber station, or to the subscriber stations having the best Rank-2 channel quality indicators to implement multi-user MIMO in multiple streams.
摘要翻译：基站能够通过从一个或多个用户站接收Rank-1 CQI值来将单用户MIMO方案与多用户MIMO方案统一起来。基站还接收来自用户站的预编码向量，然后确定哪个用户站具有最佳Rank-1 CQI值。基站然后至少部分地基于从具有最佳Rank-1 CQI值的用户站接收的矢量来确定要使用的波束形成矩阵。然后，基站使用与具有最佳Rank-1信道质量指示符的用户站相对应的波束形成矩阵向用户站广播数据，以实现到该用户站的一个或多个流中的单用户MIMO，或用户站具有最好的Rank-2信道质量指标以在多个流中实现多用户MIMO。
