FIELD: information technology.
SUBSTANCE: user terminal supports multiple spatial multiplexing (SM) modes such as a steered mode and a non-steered mode. For data transmission, multiple data streams are coded and modulated in accordance with their selected rates to obtain multiple data symbol streams. These streams are then spatially processed in accordance with a selected SM mode to obtain multiple transmit symbol streams for transmission from multiple antennae. For data reception, multiple received symbol streams are spatially processed in accordance with the selected SM mode to obtain multiple recovered data symbol streams. These streams are demodulated and decoded in accordance with their selected rates to obtain multiple decoded data streams.
EFFECT: high efficiency of using multiple terminal modes.
