Patent ID: 8213391

Claim:
A method for performing time synchronization of an access point base station with a timing of a macro base station, the method comprising: receiving an assignment message from a service provider, wherein the assignment message comprises a neighbor list, and the neighbor list comprises a signal strength of the macro base station and the timing of the macro base station; and synchronizing the access point base station with the macro base station, wherein the synchronizing comprises: searching for a strongest macro base station in the neighbor list according to the signal strength; performing slot boundary synchronization by processing a PSCH (primary synchronization channel) of the macro base station; and performing frame boundary synchronization by processing a SSCH (secondary synchronization channel) of the macro base station to detect scrambling code change on each frame: wherein the step of performing the slot boundary synchronization and the step of performing the frame boundary synchronization provides frame synchronization between the access point base station and the macro base station.
