Abstract
A method and apparatus for controlling the maximum number of retransmissions of an information packet that may be attempted if the information packet was not properly received is disclosed. The number of re-transmissions of messages is limited using maximum allowable retransmission (MAR) values. By assigning multiple MAR values over a range of possible data rates, an efficient distribution of MAR values can be assigned to the range of possible data rates to minimize the overall latency of the communication link. MAR messages are utilized to efficiently create a preferred assignment of MAR values over the range of possible data rates.
