Zusammenfassung:	Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support demodulation reference signal sharing across user equipments (UEs) supporting over the air (OTA) digital pre-distortion (DPD). For example, the described techniques provide for demodulation reference signal (DMRS) sharing across UEs supporting OTA DPD. A network entity may share a full DMRS pattern with multiple frequency-division multiplexed (FDMed) UEs. Based on the shared DMRS pattern, the UEs may evaluate the non-linear impairment by estimating non-linearity (NL) compensation function coefficients. Each of the UEs may indicate, to the network entity, their estimated NL compensation function coefficients. The network entity may apply an updated NL compensation function based on the NL compensation function coefficients from the various UEs and transmit a downlink transmission according to the updated NL compensation function.
