Abstract: Systems and techniques are provided for performing wireless communications. In some aspects, a user equipment (UE) may receive from a first wireless node via a first channel, a first transmission comprising a first artificial noise (AN) signal combined with a first data signal, wherein the first AN signal is generated based on channel state information (CSI) of the first channel. The UE may receive, from a second wireless node via a second channel, a second transmission comprising a second AN signal combined with a second data signal, wherein the second AN signal is generated based on CSI of the second channel and is different from the first AN signal. The UE can determine a data message based on the first transmission and the second transmission.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a DPD training procedure. A base station may transmit, for a plurality of iterations, a signal to at least one UE through a plurality of transmit chains and with application of DPD. The signal transmitted for each iteration may be transmitted with a BW that extends over a plurality of subcarriers and includes pilots extending over a BW subset that increases in subcarrier size for each iteration. The base station may receive, for each iteration, feedback from the at least one UE based on the transmitted signal and apply DPD to each of the plurality of transmit chains based on the feedback. Accordingly, the base station may transmit to one or more UEs through the plurality of transmit chains and with application of the DPD pilot signals that extend over the entire BW.

Abstract: A transmitter may be configured to generate a reference signal having a non-constant envelope for nonlinearity estimation by a receiver. The transmitter may transmit the reference signal. A receiver may be configured to receive, from the transmitter, the reference signal having the non-constant envelope. The receiver may estimate at least one nonlinearity characteristic based on the reference signal having the non-constant envelope. The receiver may transmit feedback based on the at least one nonlinearity characteristic and/or perform at least one digital post distortion (DPoD) operation based on the at least one nonlinearity characteristic.

Abstract: In order to enable asynchronous, autonomous reception beam switching at a UE while minimizing degradation due to a transient in link performance, a method, apparatus, and computer-readable medium for wireless communication are provided. The apparatus receives CSI-RS on different reception beams in different symbols, wherein one reception beam being a current serving reception beam, and determines whether to switch to a different reception beam based on a SPEFF metric for the different reception beam and/or a severity of a potential link transient qualified in terms of the expected CQI/MCS degradation in the channel. The apparatus may switch from a current serving reception beam to a second reception beam when a first channel quality for the current serving reception beam is within a threshold value of a second channel quality for the second reception beam, the second channel quality being measured using a current configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may use training data associated with distortion of sensing signals. Some aspects more specifically relate to correcting distortion from a sensing signal in association with the training data. In some examples, the training data may include distortion measured in an environment without a sensing target. In some examples, the training data may include distortion measured via a dedicated hardware path within the WCD. The WCD may use the training data to identify whether an object is present or may use the training data to remove distortion from a sensing signal.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit a first message indicating a capability to linearize a digital signal outputted by an analog front end of the UE, the digital signal being associated with a first transmission. The UE may receive the first transmission, the first transmission being associated with a gain state comprising a set of configurations associated with a plurality of amplifiers at the UE, and the UE may linearize the digital signal associated with the first transmission based at least in part on the gain state, where linearizing the digital signal comprises obtaining an output voltage value corresponding to an input voltage value associated with the analog front end. In some examples, the UE may obtain an output voltage value from a lookup table (LUT) of a set of LUTs configured to the UE or generated by the UE.
