A method of performing hybrid automatic repeat request (HARQ) by a source station in a wireless communication system is provided. The method includes: transmitting data to a destination station at a transmission start time; receiving an acknowledgment (ACK) or negative-acknowledgement (NACK) signal for the data from the destination station after a first transmission time interval elapses from the transmission start time; and upon receiving the NACK signal, retransmitting the data after a second transmission time interval elapses from the transmission start time, wherein the second transmission time interval is one transmission time interval selected from a plurality of predetermined transmission time intervals. Accordingly, the wireless communication system can perform a heterogeneous HARQ process in which an HARQ period, an ACK/NACK transmission start time, and the like are different.

A method for saving power in a multi-carrier wideband wireless access system is provided. A method for saving the power of a receiver in a multi-carrier wireless communication system includes acquiring multi-carrier information from a transmitter on a primary carrier, entering one or more secondary carriers satisfying a predetermined power saving mode entry condition out of one or more secondary carriers included in the multi-carrier information into a power saving mode, and receiving data during a listening interval according to the power saving mode on the one or more secondary carriers entering the power saving mode. The multi-carrier information includes at least one of information about a plurality of available carriers, information indicating the primary carrier and the one or more secondary carriers out of the plurality of available carriers, and information about the power saving mode entry condition of the one or more secondary carriers.

Disclosed are a method and apparatus for transceiving data via a contention based physical uplink data channel. A terminal apparatus, which transmits data via a contention based physical uplink data channel, comprises: a transmitter which transmits data via a contention based physical uplink data channel and scheduling request information via a scheduling request channel simultaneously or consecutively to a base station; a receiver which receives a physical hybrid-ARQ indicator channel (PHICH) or an uplink (UL) grant message from the base station; and a processor which decodes the physical hybrid-ARQ indicator channel (PHICH) or the uplink (UL) grant message to determine whether an ACK signal or a NACK signal is indicated. Here, the scheduling request channel can be a specific channel allocated to the terminal apparatus so as to discriminate the terminal from other terminal apparatuses.
