Abstract

본 문서는 복수의 구성 반송파(Component Carrier: CC)를 이용하여 통신을 수행하는 반송파 조합(Carrier Aggregation: CA) 방식 이동통신 시스템에서 단말이 기지국에 임의접속 절차를 수행하는 방법 및 이를 위한 단말 장치에 대한 것이다. CA 방식 이동통신 시스템에서 단말이 효율적으로 임의접속을 수행하기 위해 단말은 백오프 동작을 CC별로 별도로 관리하며, 특정 CC에 대한 백오프 기간 적용 중이라도 이용 가능한 다른 CC가 있는 경우 해당 CC를 이용하여 임의접속 프리엠블 전송을 수행할 수 있다.
