Abstract
Parallel demodulators are provided in field units. Forward and reverse channel allocation information may be broadcast to the field units in the same epoch as traffic data but on first and second channels, such as paging and traffic channels. This assures that all field units are able to receive forward and reverse channel allocation information every epoch. By having parallel demodulators in the field unit, switching between the first and second channels is avoided and channel allocation information is not lost.
