Abstract
Aspects of the present disclosure provide techniques for phase tracking in wireless communications using frames with some portions that use relatively long symbol durations.
Claims20
An apparatus for wireless communications, comprising:
- an interface configured to obtain a frame having one or more training fields with pilot symbols transmitted therein on one or more tones, the one or more training fields having a first symbol length that is longer than a reference symbol length;
- and
- a processing system configured to:
- determine one or more tone locations and a number of the one or more tones based on the first symbol length,
- perform channel estimation based on the training fields, and
- perform phase tracking based on the pilot symbols according to the determined tone locations and the number of the one or more tones.
