METHOD AND APPARATUS FOR PERFORMING HARQ PROCESS IN WIRELESS COMMUNICATION SYSTEM

摘要

A method for allowing a source station to perform an HARQ (Hybrid Automatic Repeat Request) process in a wireless communication system comprises: a step for transmitting data to a destination station at a transmission starting point; a step for receiving an ACK (Acknowledgement) or NACK (Negative-Acknowledgement) signal for the data from the destination station at the end of a first transmission time interval following the transmission starting point; a step for retransmitting the data at the end of a second transmission interval following the transmission starting point, wherein the second transmission time interval is one transmission time interval selected from the predetermined transmission time intervals. The wireless communication system is able to perform a heterogeneous HARQ process in which an HARQ period, ACK/NACK transmission starting point, etc. are different from each other.
