Abstract

본 명세서에서의 개시에 따르면, 반송파 집성 시스템에서 채널 상태 정보(Channel State Information: CSI) 피드백을 위한 단말의 동작 방법 방법이 제공된다. 상기 동작 방법은 복수의 하향링크 컴포넌트 캐리어 각각에 대한 채널 상태 정보 피드백 구성(CSI feedback configuration) 정보를 기지국으로부터 수신하는 단계와; 상기 수신된 채널 상태 정보 피드백 구성 정보에 기초하여, 상향링크 프라이머리 컴포넌트 캐리어의 물리 상향링크 제어 채널(Physical Uplink Control Channel: PUCCH)을 통해 채널 상태 정보를 상기 기지국으로 피드백하는 단계를 포함할 수 있다. 상기 채널 상태 정보 피드백 구성 정보는 상기 복수의 하향링크 컴포넌트 캐리어 중 어느 하나의 컴포넌트 캐리어를 통해 수신되거나 상기 복수의 하향링크 컴포넌트 캐리어 각각을 통해 수신될 수 있다.
