1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving a configuration that indicates a duration of a dormancy timer for switching from an active bandwidth part to a dormant bandwidth part configured for the UE; and
switching to communicating via the dormant bandwidth part or a default bandwidth part of the UE based at least in part on a determination that the dormancy timer has expired,
wherein the dormancy timer is configured only for a default bandwidth part of the UE or only for an initial bandwidth part, or
wherein the switching is based at least in part on a determination that the dormancy timer and an inactivity timer, for switching to the default bandwidth part of the UE, expire at a same time.
