Abstract  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 Ns data symbol streams for transmission on Ns transmission channels of a MIMO channel (3) 5 spatially spreads the Ns data symbol streams with steering matrices and (4) spatially processes Ns spread symbol streams for full-CSI transmission on Ns eigenmodes or partial-CSI transmission on Ns spatial channels ofthe MIMO channel. A receiving entity (1) obtains NR received symbol streams via NR receive antennas (2) performs receiver spatial processing for full-CSI or partial-CSI transmission to obtain Ns detected symbol streams (3) spatially despreads 10 the Ns detected symbol streams with the same steering matrices used by the transmitting entity to obtain Ns recovered symbol streams and (4) demodulates and decodes each recovered symbol block to obtain a corresponding decoded data packet. 318 start 312 Process (e.g. encode Interleave and modulate) each packet of data to obtain a corresponding block of data symbols 314 Multiplex data symbol blocks onto N s data symbol streams for transmission on N s transmission channels to a receiving entity 316 Perform spatial spreading on the N. data symbol streams with steering matrices to obtain N s spread symbol streams r318 Perform spatial processing on the Ns spread symbol streams for full-CSI or partial-CSI transmission to obtain N T transmit symbol streams 320 Condition and send the NT transmit symbol streams via N - transmit antennas End FIG. 3
