Abstract: A method for network selection in a cellular and WLAN interworked network may include determining, by a UE, an association state between the UE and a WLAN access point. The UE may select a metric of the access point, based at least in part on the determined association state. The UE may determine a value of the metric. The UE may determine whether to report the value of the metric to a base station of the cellular wireless network, based on various factors. These factors may include the association state, the value of the at least one metric relative to a threshold value, a change in the association state, or receiving a reporting instruction from the base station. The UE may report the value of the metric to a base station, based on its determination. A base station may perform operations complementary to the UE, for network selection.

Abstract: Methods, systems, and devices for wireless communications are described. A first device and a second device may communicate via a channel. The first device may generate and transmit a reference signal, which may be a distortion probing reference signal with a high peak to average power ratio. In one implementation, the first device may use the reference signal as an input for a neural network model to learn a nonlinear response of the second device transmission components. In another implementation, the second device may sample the generated reference signal, and use the samples as inputs for a neural network model to learn the nonlinear response. The first device and the second device may exchange signaling based on learning the nonlinear response, and each device may compensate for the nonlinear response when communicating via the channel.

Abstract: A base station may precode a first reference signal using a first precoder (P1) and at least one second reference signal using at least one second precoder (P2). At least two UEs may measure the first reference signal and the at least one second reference signal, and transmit channel state feedback based on the measuring (m11 and m12 for a first UE, and m21 and m22 for a second UE). The channel state feedback may comprise channel state information compressed by at least one neural network. The base station may derive a higher-level precoder (W) for multiple-input multiple-output (MIMO) downlink transmission to the at least two UEs.

Abstract: A configuration for a UE to utilize grant periodicity values that are not multiples or fractions of a slot. The apparatus receives, from a base station, a configuration for a periodicity for a configured grant, the configured grant being for communicating with the base station based on the corresponding periodicity. The apparatus communicates with the base station based on the configured periodicity in association with the configured grant, the communicating being one of receiving the plurality of PDSCHs associated with the configured grant based on the corresponding configured periodicity or transmitting the plurality of PUSCHs associated with the configured grant based on the corresponding configured periodicity.

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.

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: Methods, systems, and devices for wireless communications are described. Devices of a wireless communications system may be configured to group data packets as a batch or file. In some cases, resources may be determined based on one or more resource grants corresponding to file communication. Other aspects may include DCI configurations corresponding to file communication, resource grants may be configured to assign resources for communication of a file. For example, a DCI may be specifically configured for granting resources for communication of a file. In another example, configured grants may include a configured grant index corresponding to communication of a file. Other aspects may include configuration of a UE for responding to a preemption indication when a file is scheduled for communication, power adjustments for communication of a file, reference signal configurations for communication of a file, and/or coherent detection/transmission across two or more packets of a file.
