Abstract
Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support adaptation of digital pre-distortion (DPD) coefficients based on a temperature of a user equipment (UE). The UE may determine a power offset value based on a first temperature value associated with a training procedure for the UE, a second temperature value associated with the UE, and a constant value. The training procedure may be associated with multiple sets of coefficients for the UE. The UE may apply the power offset value to a transmission power level for transmission of a message. The UE may determine a set of coefficients of the multiple sets of coefficients based on the training procedure and the power offset value applied to the transmission power level. The UE may apply the coefficients to a DPD engine of the UE to generate the message for transmission at the transmission power level.
