Abstract: Method and apparatus for dynamic control of power amplifier back off for repeaters. The apparatus uses a channel model to model a first signal at a channel output. The channel model models a channel between a receiver and a transmitter. The apparatus performs a PAPR reduction on the first signal at the receiver to generate a second signal having a reduced PAPR. The apparatus inputs the second signal through an inverse channel model to generate an output signal. The apparatus outputs the output signal to the receiver, such that the PAPR of the output signal is reduced at an input of the receiver.

Abstract: A UE may detect, at the UE, a suspected fabricated transmission attack based on PHY security. The UE may transmit, to a network node, and the network node may receive, from the UE, an indication of the suspected fabricated transmission attack. The network node may receive, from the UE, an indication of one or more characteristics associated with a potential attacker associated with the suspected fabricated transmission attack. The UE may transmit, via a sidelink to at least one additional UE, a second indication of whether the UE identifies that the suspected fabricated transmission attack corresponds to the UE being attacked. The network node may identify a geographical location of the potential attacker based on a plurality of indications of the one or more characteristics associated with the potential attacker. The network node may compile an adversary pool including one or more compromised identities.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive, from another wireless communication device, an indication of an averaging parameter associated with a transmitter nonlinear model. The wireless communication device may estimate the transmitter nonlinear model based at least in part on the indication of the averaging parameter associated with the transmitter nonlinear model. 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, from a base station and in a first slot, an indication of a signal to noise ratio (SNR) mode, of a plurality of SNR modes, to be used by the UE for one or more downlink communications in one or more slots that occur after the first slot, wherein different SNR modes of the plurality of SNR modes support at least one of different modulation and coding schemes, different ranks, or a combination thereof; and operate using the SNR mode in the one or more slots based at least in part on the indication. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver device may receive, from a tested device, a set of sounding reference signals for a testing procedure of a test chamber; determine a set of parameters of a parasitic channel of the test chamber based at least in part on a response of a set of subcarriers of the set of sounding reference signals; determine a transmission equalization matrix based at least in part on the parameters of the parasitic channel; and equalize one or more subsequent transmissions using the transmission equalization matrix. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a digital pre-distortion (DPD) training is to be performed by a modem, wherein the modem is configured to facilitate communication between the UE and a primary network associated with the UE, and configure the modem to perform the DPD training using a secondary network associated with the UE. Numerous other aspects are provided.
