Abstract
A subscriber unit () listens to a first channel () comprising a plurality of micro-slots and a plurality of data units. The subscriber unit decodes at least a portion of a data unit on the first channel comprising a micro-slot value. The subscriber unit learns the synchronization between the first channel and a second channel () based on the micro-slot value. A first base radio () transmits a first plurality of data units on the first channel. A second base radio () transmits a second plurality of data units on the second channel. The first plurality of micro-slots on the first channel are synchronized with the second plurality of micro-slots or plurality of frame boundaries on the second channel. The first base radio transmits a message () on the first channel in at least one of the plurality of data units, wherein the message comprises at least a micro-slot value used to associate the synchronization between the first channel and the second channel.
