Claim:
1. A method of transmitting acknowledgement at a mobile station in soft handoff in a wireless communication system, the method comprising: transmitting the acknowledgement at a specific time, wherein the mobile station attempts decoding a frame earlier than a predetermined duration of the frame, wherein the decoding is performed by combining a first transmission to which a first interleaver pattern has been applied for bit-level interleaving by a first base station and a second transmission to which a second interleaver pattern has been applied for bit-level interleaving by a second base station, wherein the specific time is after a successful decoding of the frame and within the predetermined duration of the frame, and wherein a first interleaved result of the first transmission is cyclically shifted with respect to a second interleaved result of the second transmission.
