Abstract

다중 셀 기반에서의 CoMP MU-MIMO를 수행하기 위해 필요한 정보를 효율적으로 송수신하기 위한 방법이 개시된다. 이를 위해 CoMP 동작을 수행하는 기지국은 특정 기지국을 기준으로 참조신호 시퀀스를 생성하거나, CoMP ID에 기반한 동일한 참조신호 시퀀스를 생성하여 단말로 전송해 줄 수 있다. MU-MIMO 방식을 지원하며 조인트 프로세싱 방식을 수행하기 위해, 전자의 경우에 기지국은 CoMP 참조신호의 시퀀스 정보, 주파수 시프트 정보 등을 단말에 추가적으로 전송해 줄 필요가 있다. 후자의 경우에는 사전에 설정된 CoMP 세트 ID에 기반하여 CoMP 참조신호를 생성하여 단말로 전송해 줄 수 있다.
