FIELD: radio engineering, communication.SUBSTANCE: invention relates to a method and a device for controlling retransmission in user equipment which supports uplink spatial multiplexing. The method comprises the following steps: detecting uplink resolution in a physical downlink control channel (102), wherein the uplink resolution is real for at least one transport unit; detecting that at least one transport unit is blocked (103) such that resolution is not associated with at least one transport unit; and interpreting (106) at least one blocked transport unit as acknowledgement, ACK, of previous transmission corresponding to said blocked transport unit, regardless of what indicator was received in reception status feedback channel for said previous transmission.EFFECT: procedure for obtaining uplink resolution, which can be repeated simultaneously for each said resolution associated with a certain transmission time interval (TTI).12 cl, 6 dwg |
