Claim Text:
1. A method comprising: measuring, by a system including a processor, parameters associated with forward and reverse power during a transmission burst and between transmission bursts, wherein the system is integrated in a communication device; comparing, by the system, at least a portion of the parameters to a threshold, wherein the threshold is a dynamic threshold that is adjusted during operation of the communication device according to a known transmitted power level and a target return loss assigned to a communication channel being utilized by the communication device; determining, by the system, whether the parameters are valid or invalid based on the comparing; adjusting, by the system, a tunable reactance circuit of the communication device to a first tuning state according to the parameters responsive to a determination that the parameters are valid; and adjusting, by the system, the tunable reactance circuit to a second tuning state responsive to a determination that the parameters are invalid, wherein the second tuning state is a last known tuning state for a use case of the communication device that was previously determined valid.
