这种多个用户之间配对来复用相同的时频资源来实现多流的技术就叫做MU-MIMO(多用户MIMO),而一个用户内部的多流则为传统的SU-MIMO(单用户MIMO)。 目前主流的5G手机能支持4天线接收,因此可以和基站形成最多4条独立的传播路径,也就是对于单个手机来说,SU-MIMO最多可支持4流传输。 5G AAU可以同时实现MU-MIMO和SU-...
[Beijing, China, April 8, 2020] At the China Unicom Beijing and Huawei Release Conference of "5G Capital" Joint Innovation, China Unicom and Huawei jointly announced the initiation of the innovative 5G Indoor Distributed Massive MIMO solution. This solution applies 5G Massive MIMO technology to ...
Recent technology developments have made Massive MIMO the preferred option for large-scale deployments in 5G mobile networks. Massive MIMO enables state-of-the-art beamforming and MIMO techniques that are powerful tools for improving end-user experience, capacity, and coverage. ...
This paper is focused on the massive MIMO technology. Initially conceived for conventional cellular frequencies in the sub?6 GHz range (渭?Wave), the massive MIMO concept has been then progressively extended to the case in which mm?Wave frequencies are used. However, due to different propagation...
