Abstract

제1실시예에서, CDMA 시스템의 통신 유닛의 로케이션을 결정하기 위한 방법 및 장치는 확산 스펙트럼 신호를 통해 가입자(140)에 로케이션 요청을 송신하는 것과, 베이스 확산 시퀀스의 특정 심볼의 수신 시간과 가입자 확산 시퀀스의 특정 심볼의 송신 시간을 나타내는 응답 메시지를 포함하는 가입자 신호를 회답으로 수신하는 것을 포함한다. 다른 수신 베이스(들) (140)과 함께 베이스(130)도 또한 가입자 확산 시퀸스의 선정된 심볼을 수신하고, 선정된 심볼의 각각의 수신 시간을 각각 결정한다. 그후 수신된 정보는 가입자 로케이션을 결정하기 위한 인식된 베이스 로케이션과 자연 정보와 함께 프로세스된다. 충분한 수의 베이스들이 가입자와 통신할 수 있는 경우, 예를 들면, 높은 로딩/간섭으로 인해, 보조 베이스들(121)도 또한 가입자로부터의 수신 또는 가입자로의 송신을 위해 제공된다.
