Method and apparatus of transmitting control information in a wireless communication system

摘要

The present invention is directed to a wireless communication, more specifically to a method and apparatus of transmitting control information via a PUCCH in the wireless communication system, which comprises generating channel quality information and ACK/NACK information; and transmitting the channel quality information and the ACK/NACK information together via the PUCCH at a subframe, the subframe including a plurality of SC-FDMA symbols, wherein if SRS transmission is not configured at the subframe, all SC-FDMA symbols of the subframe are used for the transmission of the PUCCH, wherein if the SRS transmission is configured at the subframe, last SC-FDMA symbol of the subframe is not used for transmission of the PUCCH.

1. A method of transmitting control information via a physical uplink control channel (PUCCH) in a wireless communication system, the method comprising:
generating, by a user equipment (UE), channel quality information and acknowledgement/negative acknowledgement (ACK/NACK) information; and transmitting, by the UE, the channel quality information and the ACK/NACK information together via the PUCCH at a subframe, the subframe including a plurality of single carrier frequency division multiple access (SC-FDMA) symbols, wherein, when a next subframe of the subframe is configured for a communication between a relay and a base station, a last SC-FDMA symbol of the subframe is not used for transmission of the PUCCH and a sounding reference signal (SRS) is dropped in the subframe even when a simultaneous transmission of the SRS and the ACK/NACK information is configured to be ON, and wherein a same frequency band is used for both a communication between the UE and the relay and the communication between the relay and the base station.
