Patent ID: 8369214

Claim:
A method of receiving data at a mobile station in soft handoff in a wireless communication system, the method comprising: receiving a first sequence in a frame from a first base station, a transmission of the first sequence by the first base station including interleaving transmission data using a first interleaver pattern; receiving a second sequence in the frame from a second base station, a transmission of the second sequence by the second base station including interleaving the transmission data using a second interleaver pattern; combining the first sequence and the second sequence and decoding the combined sequence prior to an end of the frame to which the first and second sequences are allocated; and transmitting an acknowledgement prior to the end of the frame when the decoding is successfully performed, wherein the second sequence corresponds to the first sequence being cyclically shifted, and wherein a point where the mobile station attempts to perform the decoding of the combined sequence is notified to the mobile station by the first base station.
