ABSTRACT:
For data transmission with spatial spreading, a transmitting entity (1) encodes and modulates each data packet to obtain a corresponding data symbol block, (2) multiplexes data symbol blocks onto NSdata symbol streams for transmission on NStransmission channels of a MIMO channel, (3) spatially spreads the NSdata symbol streams with steering matrices, and (4) spatially processes NSspread symbol streams for full-CSI transmission on NSeigenmodes or partial-CSI transmission on NSspatial channels of the MIMO channel. A receiving entity (1) obtains NRreceived symbol streams via NRreceive antennas, (2) performs receiver spatial processing for full-CSI or partial-CSI transmission to obtain NSdetected symbol streams, (3) spatially despreads the NSdetected symbol streams with the same steering matrices used by the transmitting entity to obtain NSrecovered symbol streams, and (4) demodulates and decodes each recovered symbol block to obtain a corresponding decoded data packet.
