摘要
Massive MIMO(大规模天线)技术,是未来5G通信中的重要技术。与现有的2、8天线相比,其天线数目可达64、128根,此时,继续采用LTE(长期演进)基于码本的反馈方案,反馈量相当大,UE处理复杂。现提出一种基于子空间反馈的数据传输方案选择方法,可以大幅度减小反馈量,比较简单的实现传输方案选择和多用户配对。
Massive MIMO is a key technology to the future 5G communications. Compared with the current 2 or 8 antennas, the antenna number of it will come to 64 or 128. The feedback becomes big and UE processing becomes complexity when continue to use the LTE codebook based transmission scheme selection. This paper presents a new method of transmission scheme selection based on subspace feedback, which can greatly reduce the amount of feedback and be simple to achieve multi-user transmission scheme selection and pairing.
