FIELD: communication facilities. ^ SUBSTANCE: invention is related to device and method for transfer/reception of data in communication system with multiple antennas (MIMO). Method consists in the following. Based on information about channel condition, planner identifies terminal, to which basic station must transmit data, identifies antennas, out of multiple antennas, through which basic station must transmit data, and identifies method of spatial preliminary coding. Multiplexer multiplexes transmitted data into multiple data flows in compliance with number of identified antennas. Unit of modulation and coding realises modulation and coding at each data flow. Controller of preliminary coding produces signal of matrix selection for selection of one of multiple matrices of spatial preliminary coding in compliance with method of spatial preliminary coding. Coder of spatial preliminary coding spatially codes each of coded flows by matrix selected based on signal of matrix selection. OFDM-modulator realises OFDM-modulation on each of spatially-coded flows. ^ EFFECT: higher throughput capacity of system in OFDMA technology, using method of adaptive modulation and coding (AMC) and method of channel resources planning control. ^ 24 cl, 15 dwg |
