Abstract

Disclosed is a method for acquiring frame synchronization of a broadcasting channel (BCH) in an asynchronous mobile communication system. The method comprises acquiring system timing through a synchronization channel; performing CRC by demodulating for a predetermined time duration a primary common control physical channel (PCCPCH) based on the system information, re-designating a demodulating duration according to the CRC result, and performing CRC; and acquiring frame synchronization of the BCH when the CRC is consecutively passed at least two times.
