1. An apparatus for wireless communications, comprising:a first interface configured to:
obtain monitoring information for a downlink control channel while operating in an active state of a discontinuous reception (DRX) mode; and
obtain a downlink control information (DCI) message scheduling a downlink data message based at least in part on the monitoring information, wherein the DCI message indicates a feedback transmission opportunity (TxOP) for the downlink data message; and
a processing system configured to:
activate a first timer subsequent to the feedback TxOP for the downlink data message and based at least in part on an end of the feedback TxOP; and
activate a second timer upon expiration of the first timer, wherein the processing system remains in the active state of the DRX mode while the second timer is running.
