At least one outbound channel quality metric (OCQM) is determined by a communication unit (220) based on a first number of samples per unit of time (301). When the at least one OCQM is favorable, subsequent OCQMs for that channel are determined based on a decreased number of samples per unit of time (305). When the at least one OCQM is unfavorable, subsequent OCQMs are determined based on an increased number of samples per unit of time (306). In an alternate embodiment, the number of samples per unit of time used to determine OCQMs is based on an apparent speed of the communication unit. In yet another embodiment, the number of sample per unit of time is based in part upon a difference between a serving site OCQM and a neighboring site OCQM. In this manner, current drain on a communication unit's battery is substantially reduced, thereby extending battery life.
