13. A wireless device, the wireless device comprising:
radio circuitry configured to communicate with a wireless communication network;
processing circuitry operatively coupled to the radio circuitry and configured to control the radio circuitry and to:
determine a first sleep opportunity for the wireless device;
evaluate one or more energy-related parameters for each of a plurality of possible sleep modes for the wireless device, the plurality of possible sleep modes corresponding to varying degrees of reduced energy consumption by the wireless device, relative to a non-sleep mode;
select a first one of the plurality of possible sleep modes for the wireless device, based on said evaluating;
activate the selected sleep mode during the first sleep opportunity;
determine a second sleep opportunity for the wireless device, within a same discontinuous-receive (DRX) cycle for the wireless device;
perform a second evaluation of one or more energy-related parameters for each of the plurality of possible sleep modes for the wireless device;
select a second one of the plurality of possible sleep modes for the wireless device, based on said performing the second evaluation, the second one of the plurality of possible sleep modes differing from the first one of the plurality of possible sleep modes; and
activate the second one of the plurality of sleep modes during the second sleep opportunity.
