Abstract
A method and apparatus are provided for synchronizing over-the-air time division duplexing communication within a defined geographical coverage area (201) of a communication system (200) that provides at least cordless radiotelephone operation between a plurality of portable radiotelephone transceivers and a plurality of telepoint base stations (202, 204, 206) geographically located within the coverage area (201). The communication system (200) transmits over-the-air a synchronization timing signal (203) including timing information corresponding to a transmit-and-receive duty cycle timing for time division duplexing communication. At least one telepoint base station (204, 206) within the coverage area (201) receives the synchronization timing signal (203). The at least one telepoint base station (204, 206) synchronizes its over-the-air time division duplexing communication transmit-and-receive duty cycle timing to the timing information.
