Multi-purpose shared time domain reference signal for higher bands

A method for wireless communication at a user equipment (UE), comprising:

• transmitting a UE capability message identifying that the UE supports performing a set of functions based at least in part on a reference signal comprising a single carrier waveform and associated with single carrier signals for a plurality of symbol periods and a plurality of channels;
• receiving control signaling identifying a configuration for the reference signal, the configuration indicating the plurality of channels and the set of functions associated with the reference signal, the configuration based at least in part on the UE capability message;
• transmitting, according to the configuration, the reference signal in a first one or more symbol periods of the plurality of symbol periods;
• and
• transmitting the single carrier signals in a second one or more symbol periods of the plurality of symbol periods, wherein the set of functions are to be performed on the single carrier signals based at least in part on the reference signal.
