    摘要: 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 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.
