FIELD: information technologies.
SUBSTANCE: when subbands are used, M of used subbands are initially ordered to form multiple subband group where each of subband groups contains different subset of used subbands. Each of T transmitting antennas is associated with one or more subband groups for transmitting pilot-signal and usually with one subband group for data transmission. Pilot-signal and data may be transmitted by each of antennas in relevant subbands. For each transmitting antenna its transmitting power in each assigned to it subband can be proportionally higher so that full power available for the antenna is for transmission. Pilot-signal and/or data can be transmitted by all T antennas in all used subbands concurrently without any interference.
EFFECT: elimination of interference caused by concurrent signal transmission by multiple antennas.
