摘要: Methods for signaling precoding matrices used at the Node-B for data transmission with multiple user-multiple in multiple out (MU-MIMO) wireless communications. Precoding vectors may be efficiently signaled between wireless transmit/receive units and base stations using control channels, reference signals and blind detection of the precoding information.
