1. A method for wireless communication at a first wireless device, comprising:
identifying a set of data resource elements for transmitting data in one or more symbol periods;
identifying a set of constellation points associated with a pilot resource element of a set of pilot resource elements;
determining a value of a metric for the pilot resource element for each constellation point of the set of constellation points;
selecting, for the pilot resource element, a constellation point of the set of constellation points based at least in part on determining the value of the metric for each constellation point of the set of constellation points;
generating, for the one or more symbol periods based at least in part on the set of data resource elements, a sequence of the set of pilot resource elements associated with the set of data resource elements, the sequence of the set of pilot resource elements for transmission of a phase tracking reference signal via the set of pilot resource elements; and
transmitting, to a second wireless device in the one or more symbol periods, the set of data resource elements and the set of pilot resource elements associated with the set of data resource elements, wherein transmitting the set of pilot resource elements is based at least in part on selecting the constellation point.
