Abstract

본 발명은 반송파 결합(carrier aggregation) 환경에서 발생하는, 초기 접속 이동국과 기지국간의 모호성(ambiguity)을 해결하기 위한 접속 방법에 관한 것이다. 기지국이 서로 다른 다운링크 식별 정보를 포함하는 다운링크 메시지를 복수 개의 다운링크 반송파를 통해 전송하면, 이동국은 자신이 사용하는 다운링크 반송파를 통해 대응되는 다운링크 식별 정보를 획득한다. 이동국은 획득한 다운링크 식별 정보를 사용하여 업링크 메시지를 송신하고, 기지국은 업링크 메시지로부터 다운링크 식별 정보를 추출함으로써, 이동국이 사용하는 다운링크 반송파가 어떤 것인지 확인한다.
