Abstract

단말의 적응적 CoMP 방식 선택 방법이 개시된다. 단말은 제 1CoMP (Coordinate Multi-Point) 방식을 수행하는 동안 각 CoMP 세트 중 수신신호 대 간섭 및 잡음비 (SINR:Signal to Interference plus Noise Ratio)를 최대화할 수 있는 제 CoMP 세트를 선택한다. 그리고 단말은 상기 제 1 CoMP 세트와 상기 제 1 CoMP방식을 수행하는 동안 현재 자신의 데이터 전송률과 요구되는 최소 데이터 전송률을 비교한다. 그 후 제 1 CoMP 방식을 수행하는 단말이 상기 비교 결과에 기초하여 사전에 설정된 CoMP (Coordinate Multi-Point) 방식 순서에 따라 제 2CoMP 방식을 선택한다.
