Multi-User MIMO Brief Description: * UL MU-MIMO was introduced to take advantage of UEโs spatial isolation. * Uplink Multi-User MIMO Mid-Band enables uplink spatial multiplexing. In this way, extra PRBs are deployed throughout the entire network. Uplink spectrum efficiency is increased, hence uplink cell throughput is also increased * UL MU-MIMO supports
