Abstract： In order to solve the problems of high energy consumption and high cost in 5G communication system， a multi-antenna communi？ cation system based on transmissive reconfigurable meta-surface （RMS） is proposed， and the transceiver design， the channel model and the channel estimation in the communication system are described. Finally， the application of transmissive RMS in future communication is discussed. It is considered that the multi-antenna communication system based on transmissive RMS has a good application prospect in fu？ ture communication systems.
