Abstract:
A base station captures phase difference information between a long period spreading code of a common control channel of the base station and a long period spreading code of a common control channel of a neighboring base station of the base station from a mobile station. The base station transmits the phase difference information to a mobile station. The mobile station carries out cell search in accordance with the received phase difference information.
