Method and apparatus for transmitting ACK/NACK signal in wireless communication system

摘要

The present invention relates to a method and apparatus for transmitting an acknowledgement/not-acknowledgement (ACK/NACK) signal in a wireless communication system. The method includes the steps of: receiving a transmission block; and transmitting an ACK/NACK signal for the transmission block in a first subframe or a second subframe according to the size of the transmission block, wherein, when the size of the transmission block is smaller than or equal to a reference value, the ACK/NACK signal is transmitted in the first frame, when the size of the transmission block is greater than the reference value, the ACK/NACK signal is transmitted in the second subframe, and the second subframe is behind the first subframe in a time domain.

1. A method for transmitting an acknowledgement/not-acknowledgement (ACK/NACK) of a user equipment (UE), the method comprising:
receiving, by the UE, a first downlink control information (DCI) or a second DCI from a base station; receiving, by the UE, a transport block scheduled by the first DCI or the second DCI from a base station; and transmitting, by the UE, an ACK/NACK signal for the transport block to the base station in a first subframe or a second subframe, wherein if the UE has received the first DCI, the UE transmits the ACK/NACK signal in the first subframe and if the UE has received the second DCI, the UE transmits the ACK/NACK signal in the second subframe, and wherein the second subframe is later than the first subframe in a time domain.
