1. A user equipment (UE) for wireless communication, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
transmit an indication of a capability of the UE to communicate amplitude-modulated phase tracking reference signals (PT-RSs) on at least a first layer of a multilayered communication link that includes the first layer and a second layer; and
communicate an uplink transmission or a downlink transmission using the amplitude-modulated PT-RSs on at least the first layer of the multilayered communication link based at least in part on the indication, the amplitude-modulated PT-RSs comprising:
a PT-RS sequence indicated by phases of the amplitude-modulated PT-RSs, and
at least downlink shared channel data or uplink shared channel data that is indicated by amplitudes of the amplitude-modulated PT-RSs.
