Abstract:
A method includes: decoding frequency correction channel (FCCH) data and synchronization channel (SCH) data transmitted by a first base transceiver station (BTS) to obtain a first set of synchronization information; determining whether broadcast control channel (BCCH) data transmitted by the first BTS was successfully decoded using the first set of synchronization information; and in response to a determination that the BCCH data transmitted by the first BTS was not successfully decoded using the first set of synchronization information: determining a cause of a BCCH decoding failure; and in response to a determination that the cause of the BCCH decoding failure is stale synchronization information in the first set of synchronization information, repeating a decoding of the FCCH data and the SCH data transmitted by the first BTS to obtain a second set of synchronization information.
