Abstract: A method for a communication apparatus to align a frame boundary with a cell. A first time at which a predetermined synchronization signal is supposed to be received is determined after knowing a timing of the cell. The predetermined synchronization signal is a primary synchronization signal or a secondary synchronization signal. A second time at which the predetermined synchronization signal is actually received is determined. A first offset between the first time and the second time is determined. A timing of a local time base utilized by the communication apparatus according to the first offset is adjusted such that a frame boundary of the local time base and a frame boundary of the cell are aligned.
