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.

Abstract: In an illustrative embodiment of the present invention, a reference signal including pilot information is transmitted from a base station to one or multiple field units over a pilot channel. A message is also sent to the field units over a paging channel to indicate an effective radiated power level at which the reference signal is transmitted on the pilot channel. Based on a received power level of the reference signal at a field unit and the effective radiated power level of the reference signal, a forward path loss is estimated at the field unit for the forward link between the base station and field unit. Assuming the path loss in the reverse link is approximately the same as the estimated forward link path loss, the field unit can transmit, a reply message in the reverse link so that the base station generally receives a message at-a desired power level.

Abstract: A subscriber unit and a method for receiving data at a subscriber unit for wireless communications are provided. A subscriber unit includes a receiver and at least one processor configured to monitor and receive forward control information within a first time interval of a first slot of a plurality of slots. Each slot of the plurality of slots includes the first time interval and a second time interval subsequent to the first time interval. The receiver and the at least one processor are further configured to receive forward traffic data in the first time interval of a second slot of the plurality of slots in accordance with the forward control information, where the second slot is contiguous to the first slot.
