1. A method of wireless communication performed by a user equipment (UE), comprising:
transmitting a request to communicate an uplink shared channel transmission or a downlink shared channel transmission using amplitude modulated phase tracking reference signals (PT-RSs);
receiving an indication of a modulation and coding scheme (MCS) for symbols associated with the amplitude modulated PT-RSs; and
communicating the uplink shared channel transmission or the downlink shared channel transmission using the amplitude modulated PT-RSs based at least in part on the request and the MCS, wherein the amplitude modulated PT-RSs comprise a PT-RS sequence indicated by phases of the amplitude modulated PT-RSs and uplink shared channel data or downlink shared channel data that is indicated by amplitudes of the amplitude modulated PT-RSs, and wherein the amplitude modulated PT-RSs have a cyclic redundancy check (CRC) associated with hybrid automatic repeat request (HARQ) feedback for the amplitude modulated PT-RSs, wherein the CRC is distinct from a CRC associated with uplink shared channel data or downlink shared channel data not included in the amplitude modulation PT-RSs.
