Abstract

본 발명은 무선 통신 시스템에서 단말과 기지국 사이의 라디오 링크 실패 (radio link failure) 여부를 판단하는 방법 및 장치에 관한 것이다. 특히 반송파 결합(carrier aggregation)을 통하여 광대역을 구성하는 무선통신 시스템에서, 단말이 앵커 케리어(anchor carrier)의 라디오 링크 품질(radio link quality)과, 결합된 케리어들(aggregated carrier)의 라디오 링크 품질과, 주변 셀(neighbor cell)의 라디오 링크 품질을 순차적으로 측정하여 소정의 기준에 만족하는지 여부를 판단함으로써 효율적인 라디오 링크 실패 여부를 판단하는 방법 및 장치를 제공한다.
