Abstract

본 발명은 다중 셀/섹터(multi cell/sector) 구조의 무선 통신 시스템에서 하향링크(DL: DownLink)의 채널 정보를 획득하는 장치 및 방법에 관한 것으로, 좀 더 세부적으로 말하자면, 이동국의 채널 품질 정보와 상기 이동국에 대한 인접 셀/섹터들의 로딩 정보를 수신하고, 상기 채널 품질 정보에 포함된 CINR(Carrier to Interference and Noise Ratio)를 확인하고, 상기 로딩 정보에 포함된 상기 인접 셀/섹터들의 평균 로딩 팩터를 확인하며, 상기 인접 셀/섹터들 별 평균 로딩 팩터를 합산하여 실효 로딩 팩터를 산출하고, 상기 CINR을 상기 실효 로딩 팩터로 보상하여 상기 이동국의 채널 정보를 획득하는 것을 특징으로 하는 무선 통신 시스템에서의 채널 정보 획득 장치 및 방법에 관한 것입니다.
