Abstract

Disclosed are techniques for performing wireless communication. In some aspects, a wireless communication device may receive a signal transmission from a base station and determine a non-linear distortion power measurement associated with the signal transmission and a thermal noise power measurement associated with the signal transmission. The wireless communication device may transmit an indication of at least one of the non-linear distortion power measurement and the thermal noise power measurement to the base station.
