In a network utilizing a transmitting peer channel and a receiving peer channel, each channel having a channel gatekeeper, to transport a plurality of types of data packets each having a different priority and requesting an acknowledgment following the transmission of the data packets, a method for dynamically setting the retransmission timer value is disclosed. The method comprises the steps of waiting for the end of a channel burst for a user on the second channel, determining whether the user is requesting an acknowledgment, and determining the retransmission timer value using previous channel request statistics combined with current known gatekeeper information.

Method for setting a timer based on previous channel request statistics

A target communication device (,) determines a length of time needed to transmit outbound information. The target communication device then transmits to a sending communication device (,) an indication of a timer value based on the length of time needed to transmit the outbound information. The sending communication device receives the indication and transmits information to the target communication device. The sending communication device determines a timer length using the indication of the timer value and starts a timer, associated with the information transmitted, with the timer length determined.

Method and apparatus for starting an acknowledgment timer

A first communication device (,) transmits user data (,), divided into a plurality of data blocks, at a first modulation rate. The first communication device (,) then receives an acknowledgment (,) from the second communication device (,) indicating a quantity of the data blocks that were not received and compares this quantity to a threshold. When the quantity is less than the threshold, the data blocks that were not received are retransmitted (,) at a second, usually lower, modulation rate. Otherwise, they are retransmitted at the first modulation rate. A comparison between the quantity of data blocks to be retransmitted and a threshold is being introduced to known communication techniques by the present invention.
