METHOD AND APPARATUS FOR HARQ ACK/NACK OPERATION IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: An operation method and device of hybrid automatic repeat request (HARQ) acknowledgment/negative-acknowledgment (ACK/NACK) in a wireless communications system are provided to smoothly perform an HARQ process by transmitting channel configuration information to a terminal in advance. CONSTITUTION: An operation method of HARQ ACK/NACK includes the following steps: a step of allocating first resources to a downlink data region; a step of transmitting allocation information of the first resources to a terminal (201); a step of determining whether the current sub-frame is a physical multicast channel (PMCH) transmission sub-frame (202); a step of allocating second resources to a downlink control region; and a step of transmitting allocation information of the second resources to the terminal.
