FIELD: communication.
SUBSTANCE: for this, one of the versions of the method determines the structure of a demodulation reference signal (DMRS) for transmitting DMRS signals for transfers of rank 3 and rank 4. This DMRS signal structure determines 12 RE elements total per each physical resource block (PRB) for transmitting DMRS signals through three or four antenna ports from a set of antenna ports 7–14 for transfers of rank 3 and rank 4. DMRS signal settings for transmitting the DMRS signal in accordance with the DMRS signal structure can be determined using the downlink control information table.
EFFECT: technical result consists in reduction of costs of reference demodulation signals.
