Phase noise estimation

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory, the instructions being executable by the processor to:
• identify, at a first device, a phase noise metric associated with a receiving device;
• identify, at the first device, a transmitter phase noise metric associated with the first device based at least in part on a component configuration of the first device;
• and
• select, at the first device, a plurality of pilot tones adjacent to each other, and a plurality of null tones for a transmission to the receiving device based at least in part on the identified phase noise metric and the identified transmitter phase noise metric, the plurality of null tones being adjacent to and on both sides of the pilot tones in the frequency domain.

An apparatus for wireless communication, comprising:

• means for identifying, at a first device, a phase noise metric associated with a receiving device;
• means for identifying, at the first device, a transmitter phase noise metric associated with the first device based at least in part on a component configuration of the first device;
• and
• means for selecting, at the first device, a plurality of pilot tones adjacent to each other, and a plurality of null tones for a transmission to the receiving device based at least in part on the identified phase noise metric and the identified transmitter phase noise metric, the plurality of null tones being adjacent to and on both sides of the pilot tones in the frequency domain.

A non-transitory computer-readable medium storing computer-executable code for wireless communication, the code comprising instructions executable by a processor to:

• identify, at a first device, a phase noise metric associated with a receiving device;
• identify, at the first device, a transmitter phase noise metric associated with the first device based at least in part on a component configuration of the first device;
• and
• select, at the first device, a plurality of pilot tones adjacent to each other and a plurality of null tones for a transmission to the receiving device based at least in part on the identified phase noise metric and the identified transmitter phase noise metric, the plurality of null tones being adjacent to and on both sides of the pilot tones in the frequency domain.
