1. A method for wireless communications at a user equipment (UE), comprising:
receiving, from a base station, a first tracking reference signal configuration associated with a first bandwidth part and a second tracking reference signal configuration associated with a second bandwidth part, the first tracking reference signal configuration comprising a first set of parameters and the second tracking reference signal configuration comprising a second set of parameters;
identifying the first bandwidth part for communication with the base station over a first set of time resources and the second bandwidth part for communication with the base station over a second set of time resources, wherein the first set of time resources are different than the second set of time resources;
selecting the first tracking reference signal configuration for the first set of time resources based at least in part on the first tracking reference signal configuration being associated with the first bandwidth part; and
receiving, from the base station based at least in part on the selecting, a first tracking reference signal in accordance with the first tracking reference signal configuration.
