A network node (12) schedules a wireless communications device (14) to utilize a subsection (54) of a previously configured active bandwidth part (46). The wireless communications device (14) utilizes the subsection (54) for operations such as monitoring for control signaling from the network node (12), channel measurements, and/or for communication between the wireless communications device (14) and the network node (12) (e.g. uplink and/or downlink traffic). Accordingly, the wireless communications device (14) may reduce power consumption by not monitoring and/or using a wider bandwidth.
