Abstract: Various aspects of the present disclosure generally relate to wireless communication. Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, the described techniques can be used to improve latency and reduce power consumption of a DPoD process performed by the network node. For example, in association with identifying the one or more kernels for the subset of candidate kernels, the network node may consume a reduced amount of power and may identify the one or more kernels with reduced latency, when compared with testing each candidate kernel. Additionally or alternatively, the UE may conserve power resources by using PAs of the UE with reduced power (with an increased NL region) in association with the improved latency of the DPoD process performed by the network node.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may obtain from a user equipment (UE), a report that indicates one or more signal quality values associated with a set of communication chains of the UE. The network entity may perform a frequency domain residual sideband (FDRSB) identification procedure to determine an FDRSB correction table associated with a set of frequency bands and the set of communication chains. The network entity may output to the UE a control message indicating the FDRSB correction table that identifies which one or more frequency bands of the set of frequency bands and which one or more communication chains of the set of communication chains are associated with FDRSB correction. The UE may demodulate one or more messages via at least one communication chain of the set of communication chains based on FDRSB correction performed using the FDRSB correction table.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may apply a precoding operation to a downlink physical channel. The network node may obtain a plurality of coefficients associated with a non-linearity of the downlink physical channel in accordance with estimating a cross-correlation of a plurality of power delay profiles associated with the precoding operation. The network node may precode a physical downlink shared channel communication in accordance with a result of the precoding operation. The network node may transmit the plurality of coefficients via a physical downlink control channel communication. 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 non-linearity measurements, each non-linearity measurement being associated with a transmit antenna power amplifier. The UE may receive initial antenna information. The UE may select a first non-linearity cancellation algorithm from among a plurality of non-linearity cancellation algorithms based, at least in part, on the one or more non-linearity measurements and the initial antenna information. Numerous other aspects are described.

Abstract: A method for wireless communication at a user equipment (UE) includes receiving, from a network node, a second message including a command to update a current frequency-dependent subband impairment estimate or a command to maintain the current frequency-dependent subband impairment estimate. The method further includes canceling the frequency-dependent subband impairment in accordance with receiving the second message. The cancelling may be in accordance with: the current frequency-dependent subband impairment estimate in accordance with the second message including the command to maintain the current frequency-dependent subband impairment estimate, or an update to the current frequency-dependent subband impairment estimate in accordance with the second message including the command to update the current frequency-dependent subband impairment estimate.
