1. A method comprising: 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; performing the evaluation of the received radio frequency signal using measurements obtained within the first time period; determining, based on the evaluation, whether an event should be triggered; and triggering the event in response to a determination that the event should be triggered.
