Abstract

본 발명은 마크로 기지국의 서비스 커버리지에 복수의 초소형 기지국이 포함되는 이동통신 시스템에서 단말기의 전력 제어를 위한 기지국의 무선 자원 할당 방법에 있어서, 상기 마크로 기지국과 초소형 기지국이 공유하는 무선 자원을 설정된 기준에 따라 분할하여 그룹화하는 무선 자원 그룹화 단계, 상기 단말기가 복수의 기지국에 대해 서로 다른 자원 영역에서 최대 전송 전력을 사용하도록 상기 그룹화된 무선 자원 각각을 임의의 기지국에게 할당하는 무선 자원 할당 단계 및 상기 할당된 무선 자원 정보를 상기 단말기에게 전송하는 전송 단계를 포함하는 것을 특징으로 한다. 본 발명에 따르면, 마크로 기지국과 통신 중인 단말기와 초소형 기지국과 통신 중인 단말기 사이에 발생하는 간섭을 효과적으로 제어할 수 있다.
