The MIMO of LTE has a maximum of 8 antennas. 5G extends the MIMO of 4G LTE to 16/32/64/128 antennas, which is called Massive MIMO.Massive MIMO and beamforming (Beamforming) complement each other.Massive MIMO realizes three-dimensional precise beamforming and multi-stream multi-user multiplexing technology by integrating more radio frequency channels and antennas.Massive MIMO is responsible for agg……

First, let’s introduce the main architecture of the wireless communication system, the core network (CN), the radio access network (RAN) and the user terminal (UE), such as a mobile phone.Usually, the core network and access network concepts of each generation of communication technology (1G, 2G, 3G, 4G…) are launched and deployed simultaneously, and the core network has forward compatibility to……
