Abstract  Abstract

MIMO systems support multiple spatial multiplexing modes for improved performance and greater flexibility, including (1) a single-user steered mode that transmits multiple data streams to a single receiver over orthogonal spatial channels; Single user unsteered mode for transmitting multiple data streams from multiple antennas to a single receiver without spatial processing at the transmitter, (3) multi-user steered mode for simultaneously transmitting multiple data streams to multiple receivers with spatial processing at the transmitter, (4) a multi-user unsteered mode for transmitting multiple data streams from multiple antennas (either jointly or not) to a receiver with multiple antennas without spatial processing at the transmitter. For each set of user terminals selected for data transmission on downlink and / or uplink, the spatial multiplexing mode is selected for the user terminal set from the multiple spatial multiplexing mode supported by the system.
