Multi-user MIMO
Multi-user MIMO (MU-MIMO) is a family of multiple-input and multiple-output (MIMO) techniques in which a wireless communication system communicates with multiple users at the same time by using the spatial dimension of the radio channel. In a typical MU-MIMO system, a base station, access point, or other multi-antenna device transmits to, or receives from, several user devices over the same time-frequency resources.
