Abstract:
A base station may identify one or more signaling messages or pilots usable for identifying a combined PA and ET non-linearity model associated with the base station. The combined PA and ET non-linearity model may be associated with a PA circuitry and an ET circuitry. The PA circuitry and the ET circuitry may be associated with the base station. The base station may transmit, to the UE, and the UE may receive, from the base station, the one or more signaling messages or pilots. The UE may identify a combined PA and ET non-linearity model associated with the base station based on the one or more signaling messages or pilots. The UE may compensate for a distortion in one or more subsequent signals from the base station based on the identified combined PA and ET non-linearity model.
