Abstract
A method and system for performing initial cell search in wireless communication system wherein unsuitable cells are excluded is disclosed. Stored frequencies are searched exhaustively and initial frequencies are search non-exhaustively. Initial frequencies may be searched exhaustively in certain circumstances. When performing exhaustive initial cell searches, primary synchronization codes that lead to unsuitable cells are excluded from subsequent initial cell searches performed on the same frequency.
