摘要：
An Automatic Retransmission reQuest (ARQ) data block reception apparatus and method in a communication system is provided. In the ARQ method, an ARQ feedback Information Element (IE) is transmitted to an ARQ data block transmission apparatus. The ARQ feedback IE includes a first field for indicating a Connection IDentifier (CID) of an ARQ connection, a second field for indicating the presence/absence of an additional ARQ feedback IE after the ARQ feedback IE, a third field for indicating a type of an Acknowledgement (ACK) MAP included in the ARQ feedback IE, a fourth field for indicating a Block Sequence Number (BSN) of an ARQ data block, and m ACK MAP fields. The m ACK MAP fields each include information indicating presence/absence of an additional ACK MAP field after a corresponding ACK MAP field, and an ACK MAP indicating success/failure in normal reception for each of n ARQ data blocks, wherein m and n each denote an integer greater than or equal to 1.
