Abstract  Abstract

A MIMO system having a plurality of spatial multiplexing modes. 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 streams on a spatial channel orthogonal to a single receiver, and (2) a single from multiple antennas. Non- (non-) steered mode for transmitting a plurality of data streams to the receiver of the receiver without spatial processing at the transmitter, and (3) a plurality of receivers with spatial processing at the transmitter. (4) From multiple antennas (co-located or not equivalent) (transmitting) from multiple antennas that transmit multiple data streams simultaneously Multi-user non-steered mode for transmitting multiple data streams to receiver (s) with multiple antennas without any spatial processing. For each set of user terminals (multiple) selected for data transmission on the downlink and / or uplink, for each set of user terminals from among a plurality of spatial multiplexing modes supported by the system The spatial multiplexing mode is selected.
