Abstract: PURPOSE: A method for transiting antenna beams between sectors in a smart antenna base station system, a recording medium storing a program to realize the same, and an IMT-2000 system using the same are provided to maintain the balance of traffic loads between sectors and reduce unnecessary handoffs by transferring antenna beams between sectors according to a change in radio environments. CONSTITUTION: If a BCP(Base station transceiver Control Processor) requests a channel card to start the sector transition of antenna beams, the channel card responds to the request(S301,S302). If the BCP requests the channel card to adjust the time and power of a primary-CPICH(Common Pilot CHannel) by stages(S303), the channel card issues an internal operation order so as to adjust the power of antenna beams(S304) and induces antenna beams to be transferred between sectors(S305). Afterwards, if the transition of antenna beams to an adjacent sector is completed, the BCP requests the channel card to execute a completion procedure for the sector transition of antenna beams(S306). As the channel card responds for the completed transition, the sector transition of antenna beams is completed(S307).

Abstract: 본 발명은 이동 통신 시스템에서 채널 품질 정보 관리 방법, 상기 채널 품질 정보 전송을 위한 채널 할당 방법 그리고 그 장치에 관한 것이다.
이동 통신 시스템에서 단말기가 기지국으로 호 접속하는 경우, 단말기에 대하여 채널 품질 정보(CQI: Channel Quality Indicator)를 보고하기 위한 CQI 채널 할당을 할당한다. 특히 소정 프레임을 채널 왕복 지연 프레임수로 모듈화하고, 모듈화 값에 해당하는 프레임에서 CQI를 전송하도록 CQI 채널을 할당하여, 가능한 많은 단말기들이 CQI 채널을 할당받아서 사용할 수 있도록 한다.
또한 할당된 CQI 채널들을 통하여 전송되는 CQI 값들을 이동 평균(moving-average) 방법으로 처리하여 저장함으로써, 과거 채널 상태를 반영한 CQI가 저장 및 관리된다. 따라서 단말기와 기지국 사이의 호 단절이 발생하는 것을 방지할 수 있다.
