Dynamic wireless link adaptation

摘要

A systemmethod that adapts wireless link parameters for a wireless communication link. A measure is determined of errorssignal quality occurring in communication over a wireless link. In a case that the measure of errorssignal quality corresponds to more errors than a first predetermined threshold, communication changes from a first set of wireless link parameters to a second set of wireless link parameters. The second set of wireless link parameters corresponds to higher error tolerance than the first set of wireless link parameters. In a case that the measure of errorssignal quality corresponds to fewer errors than a second predetermined threshold, communication changes from the first set of wireless link parameters to a third set of wireless link parameters. The third set of wireless link parameters corresponds to lower error tolerance than the first set of wireless link parameters. Preferably, the measure of errorssignal quality is determined by monitoring a number of NACK messages and a number of ACK messages that occur. It is determined that the measure of errorssignal quality corresponds to more errors than the first predetermined threshold when more than a predetermined number of NACK messages occur in succession. It is determined that the measure of errorssignal quality corresponds to fewer errors than the second predetermined threshold when more than a predetermined number of ACK messages occur in succession.

id="REI-00016" date="20150721" 1. A method of dynamically adapting wireless link parameters, comprising:
determining a plurality of states, each state corresponding to a plurality of wireless link parameters; determining a plurality of thresholds for transitioning from a current state to a next state of said plurality of states, said thresholds comprising a number of NACK messages or a number of ACK messages received using said wireless link parameters for said current state; and transitioning among said plurality of states based on said thresholds, thereby dynamically adapting said wireless link parameters for a wireless link.
