Title
(EN) METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING UPLINK CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM
(KO) 무선 통신 시스템에서 상향링크제어정보 송수신 방법 및 장치
Abstract
(EN) The present invention relates to a wireless communication system and, more specifically, to a method and an apparatus for reporting channel status information. According to an embodiment of the present invention, the method for a terminal to transmit uplink control information (UCI) in a wireless communication system comprises the steps of: determining transmission timing of the channel status information (CSI); determining transmission timing of ACK/NACK information; and transmitting at least one of the CSI or the ACK/NACK information from an uplink sub-frame. If the CSI is an unavailable CSI, the CSI may be omitted and only the ACK/NACK information is transmitted from the uplink sub-frame. COPYRIGHT KIPO 2014
(KO) 본 발명은 무선 통신 시스템에 대한 것으로, 보다 상세하게는 채널상태정보를 보고하는 방법 및 장치가 개시된다. 본 발명의 일 실시예에 따른 무선 통신 시스템에서 단말이 상향링크제어정보(UCI)를 전송하는 방법은, 채널상태정보(CSI)의 전송 타이밍을 결정하는 단계; 확인응답(ACK/NACK)정보의 전송 타이밍을 결정하는 단계; 및 상기 CSI 또는 상기 ACK/NACK 정보 중 하나 이상을 상향링크 서브프레임에서 전송하는 단계를 포함하고, 상기 CSI가 유효하지 않은 CSI인 경우에, 상기 CSI는 누락되고 상기 ACK/NACK 정보만이 상기 상향링크 서브프레임에서 전송될 수 있다.
