Amplitude mirroring detection using additional shared information

A second wireless device for wireless communications, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the second wireless device to:
• communicate, with a first wireless device, control signaling comprising an indication that a crest factor reduction function is supported for waveform generation;
• receive, from the first wireless device, a control message indicating a signal clipping level and a signal amplitude mirroring level associated with the crest factor reduction function;
• and
• receive, from the first wireless device, a waveform comprising a message, wherein the control message further indicates that the waveform is in accordance with the signal clipping level and the signal amplitude mirroring level associated with the crest factor reduction function.

A method for wireless communications by a first wireless device, comprising:

• communicating, with a second wireless device, control signaling comprising an indication that a crest factor reduction function is supported for waveform generation;
• transmitting, to the second wireless device, a control message indicating a signal clipping level and a signal amplitude mirroring level associated with the crest factor reduction function;
• and
• transmitting, to the second wireless device, a waveform comprising a message, the waveform based at least in part on the crest factor reduction function, the signal clipping level, and the signal amplitude mirroring level.
