Abstract

기지국 협력 전력 제어 방법 및 이를 수행하는 기지국 장치가 개시된다. 제 1 수신부는 상기 협력 단위 내 특정 기지국이 자신의 셀 경계에 위치한 특정 단말로부터 상기 특정 단말의 평균 전송률 및 상기 특정 단말의 현재까지 최소 평균 전송률 만족 정도를 나타내는 토큰 값 정보를 수신한다. 제 2 수신부는 상기 협력 단위 내 하나 이상의 다른 기지국으로부터 각 기지국별 셀 경계에 위치한 단말의 평균 전송률, 상기 각 기지국별 셀 경계에 위치한 단말의 토큰 값 및 상기 하나 이상의 다른 기지국 각각의 현재 전력 레벨을 포함하는 정보를 수신하다. 제 1 전력 레벨 연산부는 상기 특정 단말 및 상기 협력 단위 내 하나 이상의 다른 기지국별 셀 경계에 위치한 단말의 최소 평균 전송률을 보장하는 상기 협력 단위 내 각 기지국의 제 1 전력 레벨 벡터를 계산한다. 제 2 전력 레벨 연산부는 상기 각 기지국의 현재 전력 레벨 및 상기 제 1 전력 레벨을 고려하여 상기 협력 단위 내 각 기지국의 갱신 전력 레벨인 제 2 전력 레벨 벡터를 계산한다.
