description A traffic-based subcarrier dynamic allocation control method in an OFDM wireless communication system and an apparatus therefor are disclosed. The method comprises the steps of: sensing a traffic buffer state on a communication service port between a COT apparatus and an RF apparatus; determining a dynamic mode to dynamically allocate a subcarrier based on the traffic buffer state; and performing standby processing during a switching standby time when operating in a carrier switch mode, and controlling a size of a subcarrier group according to the preset subcarrier allocation amount. OFDM 무선통신시스템에서 트래픽 기반의 서브캐리어 동적 할당 제어방법 및 그를 위한 장치를 개시한다. COT 장치 및 RT 장치 간의 통신 서비스 포트에 대한 트래픽 버퍼 상태를 감지하고, 트래픽 버퍼 상태에 근거하여 서브캐리어의 동적 할당을 위한 동작모드를 결정하며, 캐리어 스위치 모드로 동작하는 경우 스위칭 대기시간 동안 대기 처리하고, 기 설정된 서브캐리어 할당량에 따라 서브캐리어 그룹의 크기를 제어하는 OFDM 무선통신시스템에서 트래픽 기반의 서브캐리어 동적 할당 제어방법 및 그를 위한 장치에 관한 것이다.
