10. A method in a wireless communication network, the method comprising:
receiving, by an interface of a device to the wireless communication network, wireless communications from the wireless communication network;
controlling the interface, by a controller of the device, to receive unicast communications in a bandwidth part (BWP) of the wireless communication network and to receive communications in a common frequency resource (CFR) of the wireless communications to reduce a power consumption of the device using bandwidth adjustment based on presence of service activity and to continue receiving communications in an active unicast BWP based on the presence of the CFR of the wireless communications in the active unicast BWP;
starting a first timer based on a reception by the interface of one of a unicast physical downlink control channel (PDCCH), a first PDCCH or a first Medium Access Control (MAC) Protocol Data Unit (PDU) received in a configured downlink assignment; and
restarting the first timer while the first timer is running based on a reception by the interface of a second PDCCH or a second MAC PDU received in a configured downlink assignment for before a first predetermined period of time ends,
wherein controlling the interface to continue receiving communications in an active unicast BWP based on the presence of the CFR of the wireless communications in the active unicast BWP comprises controlling the interface to continue receiving communications in the active unicast BWP while the first timer is running.
