ABSTRACT:
In a TDMA cellular mobile communications system, a mobile station receives a TDM signal from a cell site and detects a sync, a timeslot assignment signal and a signal indicating the propagation delay time of signals between the cell site and the mobile station. From an assigned timeslot, a time interval from a detected frame sync to the time of transmission of a burst signal from the mobile station is determined. The propagation delay time indicated by the detected signal is subtracted from the determined time interval. When a frame sync is detected from the received TDM signal, clock pulses are counted until it corresponds to the subtracted time interval, whereupon a timing pulse is generated to cause a burst signal to be transmitted from the mobile station to the cell site.
