In radio, Multi-user MIMO (MU-MIMO) is a set of advanced MIMO, multiple-input and multiple-output (pronounced mee-moh or my-moh), technologies that exploit the availability of multiple independent radio terminals in order to enhance the communication capabilities of each individual terminal. To contrast, Single-user MIMO only considers access to the multiple antennas that are physically connected to each individual terminal. A widely-known scheme of MU-MIMO is Space-division multiple access (SDMA), which allows a terminal to transmit (or receive) signal to (or from) multiple users in the same band simultaneously.
