ABSTRACT:
A plurality of base station devices are linked together and synchronized to facilitate communication between the respective base station devices and respective downlink subscriber stations. According to one embodiment of the invention, one of the base station devices is designated as a master device, and the other base station devices are designated as slave devices. The respective base station devices are connected to each other by means of a synchronization bus. The master base station device then generates and broadcasts a future time stamp value, which is received by the respective slave base station devices. When the time stamp counter in the master base station device reaches the transmitted value, a control signal is broadcast over the synchronization bus. The slave base station devices then retrieve the time stamp value and reset their respective local time stamp counters to the received value. In this manner, the base station devices are synchronized.
