A first UE may transmit, to a second subset of one or more second UEs, one or more pilot signals associated with DPD training. The first UE may receive, from a third subset of the one or more second UEs, one or more feedback messages associated with DPD training. The one or more feedback messages may be based on the one or more pilot signals. Each second UE in the third subset of the one or more second UEs may correspond to one of the one or more feedback messages. The second UE may calculate one or more DPD parameters based on the one or more feedback messages. The second UE may transmit a first signal based on the calculated one or more DPD parameters.
