1. An apparatus for wireless communication at a user equipment (UE), comprising:
one or more memories; and
one or more processors coupled with the one or more memories and configured to cause the UE to:
transmit capability information that indicates a capability of the UE to receive tracking reference signals in accordance with at least a second portion of a tracking reference signal pattern that includes a first portion and the second portion;
receive an indication of the tracking reference signal pattern, wherein the first portion of the tracking reference signal pattern includes a first time gap between tracking reference signal symbols, wherein a combination of the first portion and the second portion of the tracking reference signal pattern includes a second time gap between tracking reference signal symbols, wherein the second time gap is shorter in time relative to the first time gap, and wherein the indication of the tracking reference signal pattern is based at least in part on the capability of the UE to receive tracking reference signals in accordance with at least the second portion of the tracking reference signal pattern; and
receive a plurality of tracking reference signals separated by the second time gap in accordance with the combination of the first portion of the tracking reference signal pattern and the second portion of the tracking reference signal pattern.
