Abstract: A terminal, a communication apparatus, a communication method and a channel predictor used in an OFDMA system are provided to prevent system degradations in a time-varying multiple channel atmosphere by determining signal transmission conditions on channel estimation information obtained according to a channel atmosphere. A terminal(200) communicates with a base station(100) in an OFDMA(Orthogonal Frequency Division Multiplexing Access) communication system. A channel estimator(260) estimates channel conditions based on the signal received from the communication apparatus to generate channel information. A signal transmission condition determiner(245) determines signal transmission conditions based on the channel information generated at the channel estimator. A transmitter(270) transmits distributed process feedback information having the signal transmission conditions to the communication apparatus.

Abstract: PURPOSE: A method and a system for allocating cell identification data are provided to improve identification performance between individual base stations in a communication system. CONSTITUTION: A management server initially allocates temporary cell identification data to a first base station(313). The first base station transmits the synchronization signal(315). The mobile terminal connected to the second base station grasps cell identification data of the synchronization signal(317). If the collision of cell identification data occurs, the second base station reports the collision of the cell identification data to a cell management server(321,323). The cell management server allocates the cell identification data to the first base station again(325).

Abstract: 본 발명은 OFDMA 통신시스템에서 이용되는 통신방법, 단말기, 통신장치 및 채널예측장치에 관한 것이다.
본 발명의 통신시스템에서는, 단말기가 기지국으로부터 수신된 데이터를 토대로 채널상태를 추정하는 채널정보를 생성하고, 채널정보를 토대로 단말기의 시변다중채널환경에 따라 후속채널의 채널예측정보를 생성하고, 이 채널예측정보를 토대로 신호송신조건을 결정한다. 이렇게 결정된 신호송신조건을 포함하는 분산처리피드백정보는 기지국으로 전송된다.
본 발명에 따르면, 채널 정보인 피드백정보를 각 사용자 단말기에서 처리함으로써, 기지국의 신호 처리량이 현저하게 감소된다. 또한, 채널환경에 따라 생성된 채널예측정보를 토대로 신호송신조건을 결정하므로, 시변다중채널환경하에서도 시스템의 성능저하를 방지할 수 있다.
