1. A baseband processor configured to, when executing instructions stored in a memory, perform operations comprising:
performing a listen-before-talk (LBT) operation on an unlicensed channel;
monitoring a channel for a channel acquisition indication from a base station; and
determining to extend a discontinuous reception (DRX) active time based on the LBT operation and the channel acquisition indication; and
communicating, via a radio frequency (RF) interface and during an active time of the extended DRX active time, data for a transmission or a reception of a communication associated with the unlicensed channel based on the LBT operation and the channel acquisition indication.
