1. An apparatus for communication at a user equipment (UE), comprising:
one or more memories; and
one or more processors coupled to the one or more memories, the one or more processors configured to cause the UE to:
measure one or more downlink transmissions in one or more frequency subcarriers received over a time period; and
transmit a null tone indication that indicates one or more locations for one or more null tones associated with demodulation, wherein the one or more locations indicated for the one or more null tones are based at least in part on the measured one or more downlink transmissions and one or more demodulation reference signals (DM-RSs).
