Patent ID: 8582506

Claim:
A method for transmitting a hybrid automatic repeat request (HARQ) feedback at a mobile station (MS) in a wireless communication system, the method comprising: receiving one downlink burst including two codewords or two downlink bursts from a base station (BS); and transmitting acknowledgement (ACK) or negative acknowledgement (NACK) feedbacks corresponding to each downlink burst of the two downlink bursts or each of the two codewords included in the one downlink burst, to the base station, wherein an orthogonal sequence is mapped to each HARQ mini tile (HMT) to form HARQ feedback channels and the ACK or NACK feedbacks are transmitted via a first HARQ feedback channel (HFBCH) included in a single HARQ mini tile (HMT), wherein the first HARQ feedback channel (HFBCH) and a second HARQ feedback channel (HFBCH) for ACK or NACK feedbacks transmission of another mobile station are included in the single HARQ mini tile (HMT), and are transmitted to the base station, wherein the first and the second HARQ feedback channels (HFBCHs) are transmitted on each of three HARQ mini tiles (HMTs), and wherein each of the three HARQ mini tiles (HMTs) is arranged in such a manner that a time region and a frequency region are not overlapped with each other.
