Abstract
(EN) The present invention relates to a method for checking the channel quality information (CQI) of a portable Internet system, and a base station supporting same. According to one embodiment of the present invention, provided is a method for checking channel quality information received from a terminal, including the steps of: checking the information type contained in the channel quality information received at a predetermined frame cycle from the terminal, and checking whether a base station and the terminal support services of the information type; checking whether the received channel quality information satisfies channel quality information report regulations according to the characteristics of the information type, if the base station and the terminal support services of the information type; and applying the received channel quality information to the system if the channel quality information report regulations are satisfied, and discarding the received channel quality information if the channel quality information report regulations are not satisfied.
(FR) La présente invention concerne un procédé permettant de vérifier les informations relatives à la qualité de la voie (CQI) d'un système Internet portable, et une station de base permettant l'exploitation de ce procédé. Un mode de réalisation décrit dans l'invention concerne un procédé permettant de vérifier les informations de qualité de voie lesquelles informations sont transmises par un terminal. Le procédé comprend les étapes qui consistent à vérifier le type d'informations contenu dans les informations de qualité de voie reçues à un cycle de trame prédéterminé depuis le terminal, puis à vérifier si une station de base et le terminal acceptent les services du types d'informations; à vérifier si les informations de qualité de voie reçues sont conformes aux normes relatives aux compte-rendus d'informations de qualité de voie en fonction des caractéristiques du type d'informations, si la station de base et le terminal acceptent des services correspondant au type d'informations; puis à appliquer les informations de qualité de voie au système si les normes relatives aux compte-rendus d'informations de qualité de voie sont respectées, et à écarter les informations de qualité de voie reçues si lesdites normes ne sont pas respectées.
(KO) 본 발명은 휴대 인터넷 시스템의 채널품질 정보(CQI) 확인 방법과 이를 지원하는 기지국에 관한 것이다. 본 발명의 실시 예에 따른 채널품질 정보 확인 방법은 단말로부터 수신되는 채널품질 정보의 확인 방법에 있어서, 단말로부터 일정 프레임 주기로 수신되는 채널 품질 정보(Channel Quality Information: CQI)에 포함된 정보 타입(Information Type)의 확인결과에 따라 기지국 및 단말이 상기 정보 타입에 따른 서비스를 지원하는지 확인하는 단계; 확인결과, 상기 기지국 및 단말이 상기 정보 타입에 따른 서비스를 지원하는 경우, 상기 수신된 CQI가 상기 정보 타입의 특성에 따른 CQI 보고 규칙을 만족하는지 확인하는 단계; 및 확인결과, 상기 CQI 보고 규칙을 만족하면 상기 수신된 CQI를 시스템에 적용하고, 상기 CQI 보고 규칙을 만족하지 않으면 상기 수신된 CQI를 폐기(Discard)하는 단계를 포함하는 것을 특징으로 한다.
