1. An apparatus for wireless communication at a user equipment (UE), comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
transmit, to a base station, information indicating at least a phase noise sharing configuration for a plurality of layers of a single-carrier communication,
wherein the phase noise sharing configuration indicates whether multiple layers of the plurality of layers share phase noise;
receive, from the base station, a phase tracking reference signal (PTRS) configuration for the plurality of layers based at least in part on the phase noise sharing configuration,
wherein the PTRS configuration is associated with each layer, of the plurality of layers, including a plurality of PTRSs at different times within a symbol, and
wherein a PTRS of a first layer, of the plurality of layers, is aligned in time with a PTRS of a second layer of the plurality of layers; and
perform the single-carrier communication in accordance with the PTRS configuration.
