OPTIMAL USER PAIRING FOR DOWNLINK MULTIUSER MIMO

摘要

A method includes operating a transmitter connected with nt transmit antennas serving K users having nr receive antennas each; and scheduling which users are to be simultaneously served in a same time-frequency-code slot. A particular user pairing configuration is denoted by &pgr; within a set of all configurations &Pgr;, and scheduling includes expressing mutual information as an additive objective function and maximizing the additive objective function over a particular choice of &pgr;&egr;&Pgr;.
