FIELD: radio engineering, communication.
SUBSTANCE: invention relates to wireless communication systems. User Equipment (UE) transmits an acknowledgement signal in response to the reception of multiple scheduling assignments (SA) transmitted by a base station. The SA consist of information elements (IE) including a transmission power control (TPC) IE providing adjustment for the transmission power of the acknowledgement signal. The TPC IE in a first SA of the multiple SA is used to provide the previous adjustments and the TPC IE in the remaining of the multiple SA are used to provide an indication of the resource used for transmitting the acknowledgment signal.
EFFECT: efficient determination of rules for allocating resources when transmitting acknowledgement signals to UE.
