1. A method for wireless communication at a network device, comprising:
establishing a communication link with a user equipment (UE);
selecting, based at least in part on establishing the communication link with the UE, a type of machine learning to be used by the network device for modifying one or more signals;
receiving, from the UE, one or more feedback messages indicative of a decoding outcome of a signal communicated from the network device to the UE;
inputting, based on the one or more feedback messages, the decoding outcome into an algorithm for peak to average power ratio reduction that supports the type of machine learning;
selecting, based at least in part on an output of the algorithm that supports the type of machine learning, a signal suppression technique from a plurality of different signal suppression techniques comprising clipping a peak amplitude of a downlink signal, passing the downlink signal through a filter, and a combination of clipping the peak amplitude of the downlink signal and passing the downlink signal through the filter;
modifying the downlink signal using the signal suppression technique; and
transmitting, to the UE over a downlink channel, the modified downlink signal and information indicating the modification of the downlink signal.
