Abstract
A method and apparatus for Automatic Repeat reQuest (ARQ) feedback in a wireless communication system. The ARQ feedback method includes checking whether feedback transmission on received ARQ blocks with a Cumulative ACK type is possible, and performing ARQ feedback transmission with the Cumulative ACK type when the feedback transmission with the Cumulative ACK type is possible; calculating the number of blocks to be transmitted feedback with a Cumulative ACK with Block Sequence ACK type and the number of blocks to be transmitted feedback with a Cumulative with Selective ACK type, when the feedback transmission with the Cumulative ACK type is not possible; selecting a feedback type by comparing the number of blocks to be transmitted between the Cumulative ACK with Block with Block Sequence ACK type and the Cumulative with Selective ACK type; and performing ARQ feedback with the selected feedback type.
