Abstract: A method of wireless communication, by a user equipment (UE), includes receiving multiple neural network training configurations for channel state feedback (CSF). Each configuration corresponds to a different neural network framework. The method also includes training each of a group of neural network decoder/encoder pairs in accordance with the received training configurations. A method of wireless communication, by a base station, includes transmitting multiple neural network training configurations to a user equipment (UE) for channel state feedback (CSF). Each configuration corresponds to a different neural network framework. The method also includes receiving a neural network decoder/encoder pair trained in accordance with the training configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a client may determine, using a conditioning network and based at least in part on an observed environmental vector, a set of client-specific parameters. The client may determine a latent vector using a client autoencoder and based at least in part on the set of client-specific parameters and the set of shared parameters. The client may transmit the observed environmental vector and the latent vector to a server. Numerous other aspects are provided.

Abstract: The present disclosure provides for adaptive resource management in new radio operations that adapts a numerology including a subcarrier spacing and/or cyclic prefix for a user equipment (UE) traveling at a high speed. A base station may transmit via a plurality of remote radio heads (RRH) to a user equipment (UE) is moving along a high speed track. The base station may transmit, in a first time period, using a first numerology including a first subcarrier spacing and a first cyclic prefix ratio, a first transmission for the UE. The base station may transmit, in a subsequent time period, using a second numerology including a second subcarrier spacing and a second cyclic prefix ratio, a second transmission for the UE. At least one of the second subcarrier spacing is different than the first subcarrier spacing or the second cyclic prefix ratio is different than the first cyclic prefix ratio.

Abstract: Wireless communications systems may configure a subset of allocated resources (e.g., one or more resource elements (REs) of one or more allocated resource blocks (RBs)) as peak reduction tones (PRTs) for a peak-cancelation signal. For instance, wireless communications systems may configure a fixed PRT allocation based on a Costas array. In some examples, each column of a Costas array may correspond to a RB of a set of allocated resources. A transmitting device may thus identify one or more PRT REs based on the Costas array and a mapping of allocated RBs to the columns of the Costas array. For instance, a transmitting device may identify a pattern of PRT REs to use for a peak-cancellation signal based at least in part on a configured Costas array (e.g., where the peak-cancellation signal may reduce peaks of a corresponding data signal to ultimately reduce peak-to-average power ratio (PAPR) of a transmission).

Abstract: Wireless communications systems and methods related to determining a QCL for receiving a reference signal are provided. A user equipment (UE) determines a QCL configuration for receiving a reference signal during a first time period based on a transmit beam direction to be used for transmission during the first time period. The user equipment receives the reference signal using a first receive beam direction based on the QCL configuration while transmitting a first communication signal using the transmit beam direction in a common frequency band during the first time period.

Abstract: Bandwidth part (BWP) configurations supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. Full duplex (FD) frequency-based BWP configurations may, for example, be configured as a subset of defined BWP resources for supporting full duplex operation by base stations and/or user equipments (UEs). Usable bandwidth of a FD frequency-based BWP configuration may be selected from half duplex frequency-based BWPs in legacy BWPs. Bandwidths of usable BWPs for a FD frequency-based BWP configuration may be selected so as to be non-overlapping in frequency. Transition between configurations and modes (e.g., between full duplex frequency-based BWP configurations, between half duplex and full duplex modes, etc.) may be managed to avoid periods in which a communication device cannot perform any uplink or downlink transmissions due to switching between defined BWP configurations, or otherwise reduces BWP switching time. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may interleave a signal, that is to be transmitted using discrete Fourier transform (DFT) spread orthogonal frequency-division multiplexing (DFT-s-OFDM), and a negative of the signal to obtain an interleaved signal prior to performing a DFT on the interleaved signal. The UE may transmit a DFT-s-OFDM signal that is based at least in part on the interleaved signal. Numerous other aspects are provided.
