FIELD: physics, communications.
SUBSTANCE: invention relates to communication engineering and is intended for sending acknowledgement (ACK) information in a wireless communication system. In one design, user equipment (UE) may receive multiple codewords in at least one downlink subframe. The UE may decode the multiple codewords and may determine ACK or negative acknowledgement (NACK) for each codeword based on the decoding result. The UE may bundle the ACK and NACK for the multiple codewords to obtain bundled ACK information. In one design, the UE may generate (i) a bundled ACK if ACK are obtained for all codewords, or (ii) a bundled NACK if a NACK is obtained for any codeword. The UE may send the bundled ACK information as feedback for the multiple codewords. The UE may receive retransmissions of the multiple codewords if a bundled NACK is sent and may receive new codewords if a bundled ACK is sent.
EFFECT: high accuracy of received information.
