Abstract

A method includes determining a first time period during which evaluation should be performed of whether a received radio frequency signal meets at least one criterion, the first time period based at least partially on a second time period of discontinuous reception or transmission. The method also includes performing the evaluation of the received radio frequency signal using measurements obtained within the first time period, and determining, based on the evaluation, whether an event should be triggered. The method further includes triggering the event in response to a determination that the event should be triggered.
