Abstract  Abstract

A MIMO system supports multiple spatial multiplexing modes for improved performance and greater flexibility. These modes may include (1) a single-user steered mode that transmits multiple data 5 streams on orthogonal spatial channels to a single receiver (2) a single-user non-steered mode that transmits multiple data streams from multiple antennas to a single receiver without spatial processing at a transmitter (3) a multi-user steered mode that transmits multiple data streams simultaneously to multiple receivers with spatial processing at a transmitter and (4) a multi-user non-steered mode that transmits multiple data streams from multiple antennas (co-located or non co-located) without spatial 0 processing at the transmitter(s) to receiver(s) having multiple antennas. For each set ofuser terminal(s) selected for data transmission on the downlink and/or uplink a spatial multiplexing mode is selected for the user terminal set from among the multiple spatial multiplexing modes supported by the system. 13/13 1400 Start 1412 Perform receiver spatial processing on first plurality of received symbol streams inaccordance with first spatial multiplexing mode (e.g. single-user steered mode) to obtain first plurality of recovered data symbol streams 1414 Demodulate and decode the first plurality of recovered data streams inaccordance with first plurality of rates to obtain first plurality of decoded data streams f1416 Perform receiver spatial processing on second plurality of received symbol streams inaccordance with second spatial multiplexing mode (e.g. non-steered mode) to obtain second plurality of recovered data symbol streams <1418 Demodulate and decode the second plurality of recovered data streams inaccordance with second plurality of rates to obtain second plurality of decoded data streams End FIG. 14
