Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, to each user equipment (UE) of a set of UEs, a different respective set of one or more training parameters for a digital pre-distortion procedure. Some or all of the UEs may determine one or more respective training values based on the one or more training parameters, where the training values from the UEs support the base station computing a set of non-linearity coefficients for the digital pre-distortion procedure. The base station thus may receive training parameters from some or all of the UEs and determine the set of non-linearity coefficients based thereon. The base station use the non-linearity coefficients to perform the digital pre-distortion procedure for one or more downlink transmissions, to one or more UEs of the group of UEs used for training, or to one or more other UEs.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, from a base station, control signaling identifying a measurement configuration for one or more non-linear estimation measurements of reference signals associated with a power amplifier configuration of the base station, receiving, from the base station, the reference signals on a set of resources identified by the measurement configuration, performing one or more non-linear estimation measurements associated with the power amplifier configuration of the base station based on the received reference signals, and transmitting, to the base station according to the measurement configuration, a measurement report based on the one or more non-linear estimation measurements.

Abstract: Certain aspects of the present disclosure provide techniques for over-the-air digital pre-distortion (DPD) kernel function selection. A method that may be performed by a user equipment (UE) includes transmitting capability information to a base station (BS), indicating a capability of the UE for performing digital pre-distortion (DPD) training, receiving, based on the capability information, a request from the BS to perform the DPD training, performing, based on the received request, the DPD training, wherein performing the DPD training includes: receiving one or more reference signals (RSs) and selecting, based on the one or more RSs, an ordered set of kernel functions. Additionally, the method may include transmitting feedback information to the BS indicating the ordered set of kernel functions.
