Method and device for terminal to execute uplink HARQ operation in wireless communication system

摘要

Disclosed in the present invention is a method for a terminal to receive an acknowledgement/negative-ACK (ACK/NACK) from a base station in a wireless communication system. More specifically, the method comprises the steps of receiving from the base station, through a first carrier wave, scheduling information on uplink data to be transmitted through a second carrier wave, transmitting the uplink data to the base station through the second carrier wave, and receiving an ACK/NACK signal for the uplink data from the base station, in one specific subframe from the first carrier wave or the second carrier wave.

1. A method for receiving an acknowledgement/negative-ACK (ACK/NACK) signal from a base station at a user equipment in a wireless communication system, the method comprising:
receiving, from the base station, Almost Blank Subframe (ABS) pattern information of a first carrier; receiving, from the base station, through the first carrier, scheduling information on uplink data to be transmitted through a second carrier; transmitting the uplink data to the base station through the second carrier; and receiving an ACK/NACK signal for the uplink data from the base station through a specific subframe of a carrier among the first carrier and a third carrier, wherein the carrier for receiving the ACK/NACK signal is determined based on the ABS pattern information indicating whether or not the specific subframe of the first carrier is an ABS, and wherein, when the specific subframe of the first carrier is a non-ABS, the ACK/NACK signal is received via a Physical hybrid ARQ Control Channel (PHICH) on a control region of the specific subframe of the first carrier.
