Claim:
A method of receiving data in a wireless communication system, comprising: receiving signaling indicating a bundling configuration supported by higher layer for bundling acknowledgements (ACKs) or negative acknowledgements (NACKs); receiving multiple codewords in at least one subframe; decoding the multiple codewords; determining an ACK or NACK for each codeword based on decoding result for the codeword; bundling ACKs and NACKs for the multiple codewords to obtain bundled ACK information in accordance with the bundling configuration, each bundled ACK/NACK comprising a bundled ACK or a bundled NACK for one set of codewords; sending the bundled ACK information as feedback for the multiple codewords; and receiving retransmission of at least a subset of the multiple codewords for which a bundled ACK is not sent.
