Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for performing wireless communication using digital post distortion, for example, with a large antenna array where the number of transmit antennas may be greater than a number of spatial streams. A transmitting device and a receiving device determine a perturbed precoding matrix based on a precoding perturbation rule. The transmitting device precodes a signal using the perturbed precoding matrix and transmits via the number of antennas greater than the number of spatial streams. The receiving device receives the signal and subtracts non-linearities from the received signal based on a channel estimation using the perturbed precoding matrix over one or more iterations.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may indicate, to a user equipment (UE), when it changes a power amplifier (PA) non-linearity model. The base station may transmit a set of parameters for the PA model, and a set of parameters for a non-linear equalizer function for the UE to use during a digital post-processing procedure (DPoD). The base station may indicate, to the UE, a lookup table, a vector of lookup tales, a set of kernels (e.g., from which the UE may estimate the coefficients of the PA model), or a set of both the kernels and the coefficients for the PA model. Similarly, for the non-linear equalizer function, the base station may indicate an explicit indication of the function, or may indicate a lookup table, or a kernels series (e.g., with or without corresponding coefficients).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating a capability of the UE to perform bandwidth-limited envelope tracking or a capability of the UE to compensate for bandwidth-limited envelope tracking distortion. The UE may receive a request for the UE to activate bandwidth-limited envelope tracking or a request for the UE to compensate for bandwidth-limited envelope tracking distortion. In some examples, the UE may transmit an uplink message using a bandwidth-limited envelope tracking configuration. In other examples, the UE may receive a downlink message and use digital post distortion (DPoD) to correct bandwidth-limited envelope tracking distortions in the downlink message. Aspects of the present disclosure may enable the UE to use bandwidth-limited envelope tracking and DPoD for wideband signal transmissions, which may result in lower power consumption at the UE.

Abstract: Certain aspects of the present disclosure provide techniques for envelope tracking schemes for a node in a wireless communication network. One aspect provides a method for wireless communication by a transmitter device. The method generally includes: combining envelopes associated with subbands of an input signal to be amplified for transmission based on a combination function; amplifying, via an amplifier, the input signal to generate a transmission signal, the input signal being amplified based on a combined envelope signal, representing the combination of the envelopes, received at a supply input of the amplifier; and transmitting the transmission signal to a receiver device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication of a change in a non-linearity model associated with a power amplifier of the base station. The UE may update a model associated with the power amplifier based at least in part on the indication. The UE may further update at least one parameter associated with slicing received signals based at least in part on the indication. In some aspects, the UE may use at least two coefficients when slicing. Numerous other aspects are described.

Abstract: Aspects relate to reconstructing a received non-linearly distorted (e.g., clipped) signal. A transmitting device may non-linearly distort a signal to be transmitted (e.g., by clipping peaks of the signal). This non-linear distortion may adversely affect decoding of the signal at a receiving device. To improve decoding performance at the receiving device, the transmitting device provides information regarding some of the non-linear distortion (e.g., information regarding a subset of the peaks that have been clipped) to the receiving device. The receiving device may reconstruct the signal based on this information (e.g., by reconstructing the subset of the peaks and adding the reconstructed peaks to the received clipped signal). In addition, the receiving device estimates the remaining non-linear distortion in the reconstructed signal (e.g., due to clipped peaks that were not indicated in the clipping information) by slicing the reconstructed signal and clipping the sliced signal, and provides a final reconstructed signal.

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.
