English Description：
Application backgroundUsed in energy consumption of Multi-user systems with mobility.MU-MIMO systems work with multiple antennas at the base station serving number of user terminals with single antenna.Number of antennas at the base station is fewer(less than 10).For example,in LTE the number of base station antennas is eight.Key Technology Key technology is multi-user MIMO. MIMO has the advantage of spatial diversity but the limitation is it is sensitive to propagation environment.The multiplexing gain of MIMO systems can further be exploited by MU-MIMO systems which serves number of single-antenna users.For example,it finds applications in LTE where the number of base station antennas is eight.
