Abstract:
1. A method of transmitting data in a wireless multiple-input multiple-output (MIMO) communication system, comprising: coding and modulating a first plurality of data streams to obtain a first plurality of data symbol streams; using a steered spatial multiplexing mode, spatially processing the first plurality of data symbol streams with a first plurality of steering vectors to obtain a first plurality of transmit symbol streams for transmission from a plurality of antennas to a first user terminal in a first transmission interval; coding and modulating a second plurality of data streams to obtain a second plurality of data symbol streams; and using a non-steered spatial multiplexing mode, providing the second plurality of data symbol streams as a second plurality of transmit symbol streams for transmission from the plurality of antennas to a second user terminal in a second transmission interval.
