METHODS AND APPARATUS TO TRANSMIT AND RECEIVE SYNCHRONIZATION SIGNAL AND SYSTEM INFORMATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

A base station transmits primary synchronization channels (PSC) to a mobile station through the slot of the sub frame of a frame based wireless communication system. Also, the base station transmits secondary synchronization channels to the mobile station through the slot of a sub frame. The mobile station determines a preference receiving beam based on the continuous primary synchronization channel symbols received.
