跨层5G多通道联合收发技术算法研究

Research on Algorithm of cross layer 5g multi-channel joint transceiver technology

文章提出一种多通道联合收发技术解决方案,通过利用一个或多个RRU的不同通道进行联合接收和发送,突破传统DAS只能实现单流或者双流传输的限制,使传统室分也具备多天线收发的能力,实现传统室分支持5G多流,提升5G用户感知。同时通过算法优化,避免了多通道联合收发技术解决方案引入的功率不平衡等问题,获得最佳性能。

Multi-channel joint receiving and sending technology solution,through the use of one or more different channels of RRU for joint receiving and sending,breaks through the limitation that traditional DAS can only achieve 1-stream or 2-stream transmission,enables the traditional room to also have the ability of multi-antenna transmission,realizes the traditional room to support 5G multi-stream,and improves the perception of SG users.At the same time,the problem of power imbalance introduced by multi-channel joint transceiver technology solution is avoided through algorithm optimization,and the best performance is obtained.
