Abstract:
1. A method of transmitting data in a wireless multiple-access multiple-input multiple-output (MIMO) communication system, comprising: selecting at least one user terminal for data transmission; selecting a spatial multiplexing mode, from among a plurality of spatial multiplexing modes supported by the system, to use for the at least one user terminal, wherein the spatial multiplexing mode is selected between a steered spatial multiplexing mode and a non-steered spatial multiplexing mode; selecting a plurality of rates for a plurality of data streams to be transmitted via a plurality of spatial channels of a MIMO channel for the at least one user terminal; and scheduling the at least one user terminal for data transmission with the plurality of selected rates and the selected spatial multiplexing mode; and sending information regarding the scheduling to the at least one user terminal via a wireless channel.
