Abstract: Methods for sequencing datagram transmissions are disclosed, including, receiving an unqueued segment to be enqueued in a queue. The queue comprises at least one segment. Determining a priority level and a number of attempted transmissions for the unqueued segment (100). If the unqueued segment is enqueued in front of a segment belonging to a datagram in the queue, and at least one segment belonging to the datagram has been transmitted before all the segments belonging to the datagram have been transmitted, at least one of the following functions is performed: discarding any remaining segments belonging to the datagram in the queue, transmitting any remaining segments belonging to the datagram in the queue, and re-enqueuing segments belonging to the datagram at the same location in the queue as the partially transmitted datagram, but with a different identifier.

Abstract: 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.

Abstract: A modulator (102) modulates a plurality of symbols to create a modulated signal. A transmitter is coupled to the modulator (102). The transmitter transmits the modulated signal if the modulated signal is above a threshold. A minima enlarger (104) is coupled to the modulator (102). The minima enlarger (104) computes an adjustment to the plurality of symbols if the modulated signal is below the threshold. A summer (106) is coupled to the modulator (102) and the minima enlarger (104). The summer (106) adds the adjustment to the plurality of symbols if the modulated signal is below the threshold.
