摘要： A method for the selection of forward error correction (FEC)/constellation pairings (800) for digital transmitted segments based on learning radio link adaptation (RLA) including formatting a packet transmission having a predetermined number of information bits (801). The packet is then split into a plurality of segments (803) where an RLA is used (805) to determine the optimum format of the packet. The plurality of segments is then sent to a channel encoder for FEC encoding and symbol mapping (807) at a rate selected by the RLA. The segments are then formatted into packet blocks (809) and transmitted in blocks that form a time slot at a constant symbol rate.

摘要： An outbound message (200) identifies a slot type associated with each timeslot in a scheduling period. In one embodiment, the outbound message further identifies at least an address of a first subscriber group assigned to transmit in a first timeslot (206) if the slot type of the first timeslot is of a first type and an address of a second subscriber group assigned to transmit in a second timeslot (208) if the slot type of the second timeslot is of a second type, wherein the first type and the second type could be the same or different. In a second embodiment, the outbound message further identifies at least a group address associated with a plurality of subscriber units assigned to transmit in a first timeslot if the slot type of the first timeslot is of a first type. In yet a third embodiment, the outbound message further identifies an address of a first subscriber group assigned to transmit in a first timeslot if the slot type of the first timeslot is of the first type, and a second timeslot (210) of a second type.

摘要： Systems and methods for managing power consumption in a device include toggling an ON-OFF setting of apparatus, which controls a carrier detector. The toggling is carried out according to a first duty cycle having a fixed OFF-time duration and a first dwell time having a first dwell time duration during which the carrier detector performs radio frequency carrier detection function. The device receives at least one input that affects the radio frequency carrier detection function, and the first duty cycle is changed to a second duty cycle. The toggling is carried out according to the second duty cycle, which has the same fixed OFF-time duration of the first duty cycle and a second dwell time having a second dwell time duration that is longer than the first dwell time duration, during which the radio frequency carrier detection function is performed.
