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, an UE may receive an indication of a configuration for receiving reference signals (RSs) and for transmitting a digital pre-distortion (DPD) measurement. The UE may receive the RSs from a network node. The UE may transmit a first signal that indicates the DPD measurement as observed via the RSs at the first UE, the first signal configured for coherent combination over the air with a second signal that indicates a DPD measurement as observed via the RSs at a second UE, the first signal and the second signal scheduled for transmission via overlapping network resources. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more indications of parameters associated with one or more downlink communications transmitted to one or more additional UEs. The UE may receive a downlink communication, including applying digital post distortion (DPoD) correction based at least in part on measurements of the one or more downlink communications transmitted to the one or more additional UEs and the one or more indications of the parameters. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A second wireless device may perform an enhanced non-linearity correction procedure. For example, the second wireless device may transmit, to a first wireless device, a capability report and, additionally, or alternatively, a request for a statistical attribute report associated with a power amplifier (PA) of the first wireless device. The statistical attribute report may include one or more statistical attributes associated with one or more PA coefficients for the PA. The second wireless device may receive, in response to the request, the statistical attribute report and a data signal based on the one or more PA coefficients for the PA from the first wireless device. The second wireless device may perform, based on the statistical attribute report and the data signal, an enhanced non-linearity correction procedure on the data signal.

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.
