Abstract

본 발명의 일 실시예에 의하면 캐리어 집성(Carrier Aggregation)을 이용하여 비연속적인 리소스를 단말에 할당하기 위한 스케줄링 방법을 제공한다. 상기 스케줄링 방법은 상기 단말로부터 전력 잔여량에 대한 보고(Power headroom Report)를 수신하는 단계와; 할당되지 않고 남아 있는 리소스 블록들(Resource Blocks) 중에서 상기 전력 잔여량에 대한 보고에 기초하여, 상기 단말에 할당할 비연속적인 리소스 블록들을 결정하는 단계를 포함할 수 있다. 여기서 상기 결정된 비연속적인 리소스 블록들은 불필요 방사의 발생을 억제할 수 있다. 상기 스케줄링 방법은 상기 결정된 비연속적인 리소스 블록들을 상기 단말에 할당하는 단계를 더 포함할 수 있다.
