1. A user equipment (UE) for wireless communication, comprising:
one processor one or more memories storing processor-executable code; and
one or more processors coupled with the one or more memories and individually or collectively configured to, when executing the code, cause the UE to:
determine a tracking reference signal (TRS) pattern to be used for receiving a TRS, the TRS pattern indicating:
a plurality of TRS symbols of the TRS within a slot,
a first quantity of resource blocks allocated in a first TRS symbol in the slot, and
a second quantity of resource blocks allocated in a second TRS symbol in the slot, the first quantity of resource blocks being different than the second quantity of resource blocks; and
receive the TRS in the slot based at least in part on the TRS pattern.
