Ue indication of null tone placement for demodulation

An apparatus for wireless communication at a base station, comprising:

• a memory;
• and
• at least one processor coupled to the memory, the memory and the at least one processor configured to:
• transmit, to a user equipment (UE), one or more downlink transmissions in one or more frequency subcarriers over a time period;
• receive, from the UE, a null tone indication indicating one or more locations for one or more null tones;
• and
• transmit, to the UE, one or more subsequent downlink transmissions, the one or more subsequent downlink transmissions including at least one null tone at the one or more locations for the one or more null tones.
