Abstract: A method of wireless communication by a base station detects a UE is in a high speed train scenario. The method also instructs the UE to enter a high speed train (HST) mode when the UE is detected to be in the high speed train scenario. The method further performs beam management in accordance with the HST mode. A UE (user equipment) for wireless communication detects when the UE is in high speed train scenario. The UE also reports the high speed train scenario to a base station and then receives instructions from the base station to enter a high speed train (HST) mode. The UE performs beam management in accordance with the HST mode.

Abstract: A method of wireless communications by a sidelink UE (user equipment) includes receiving a first signal as part of a discontinuous reception (DRX) wake-up procedure at the beginning of a sidelink discontinuous reception (DRX) ON duration. The method also includes transmitting a response to the first signal as part of a DRX wake-up procedure. The method further includes starting a timer after sending the response. The method still further includes entering a sleep state upon not receiving a physical sidelink control channel (PSCCH) or physical sidelink shared channel (PSSCH) before the timer expires.

The method also includes training the CSI decoder and CSI encoder based on observed channel and interference conditions to obtain updated decoder coefficients and updated encoder coefficients. The method further includes receiving an indication of resources for transmission of the updated encoder coefficients and updated decoder coefficients. The method includes transmitting the updated decoder coefficients and updated encoder coefficients to the base station in accordance with the indication of resources. Further, the method includes receiving an updated CSI decoder and updated CSI encoder from the base station for further training.

Abstract: A method of wireless communication, executed by a user equipment (UE), receives, from a base station, a broadcast or multicast message including a known payload, as well as a configuration for the known payload. The method also trains an artificial neural network with the known payload. A method of wireless communication, executed by a base station, configures a known payload for multiple UEs and signals, to the UEs, an indication of which physical channel will include the known payload, as well as time/frequency resources of the known payload. The method also broadcasts or multicasts the known payload to facilitate neural network training at the UEs.

Abstract: A method of wireless communication at a transmitting device includes adding parity check bits to a set of information bits. The method also includes generating a non-coherent transmission signal by mapping the parity check bits and the set of information bits into a sequence of complex symbols. Further, the method may include transmitting the non-coherent transmission signal to a receiving device. A method of wireless communication at a receiving device includes receiving, from a transmitting device, a non-coherent signal having at least one segment. Each segment comprises a sequence of complex symbols corresponding to information bits and parity check bits. The method also includes jointly detecting the sequences from each segment of the received non-coherent signal by using the parity check bits.

Abstract: A method of wireless communication by a user equipment (UE) may include receiving a message requesting estimated channel characteristics of a secondary band based on measuring characteristics of a channel in the primary band. The method also includes measuring characteristics of the channel in the primary band. The method estimates channel characteristics of the secondary band based on the primary band characteristics measurements. The estimating may occur without measuring signals in the secondary band. Further, the method may report the estimated channel characteristics of the secondary band and receive an indication of a secondary cell group, based on the estimated channel characteristics of the secondary band.

Abstract: A method for processing an image is presented. The method locates a subject and an object of a subject-object interaction in the image. The method determines relative weights of the subject, the object, and a context region for classification. The method further classifies the subject-object interaction based on a classification of a weighted representation of the subject, a weighted representation of the object, and a weighted representation of the context region.

Abstract: A method of constraining data represented in a deep neural network is described. The method includes determining an initial shifting specified to convert a fixed-point input value to a floating-point output value. The method also includes determining an additional shifting specified to constrain a dynamic range during converting of the fixed-point input value to the floating-point output value. The method further includes performing both the initial shifting and the additional shifting together to form a dynamic, range constrained, normalized floating-point output value.

Abstract: A radio frequency (RF) integrated circuit (RFIC) switch multi-finger transistor includes a first dual gate transistor having a first gate with a first gate length on a first side of a substrate, and a second gate with a second gate length on a second side of the substrate. The RFIC also includes a second dual gate transistor having a third gate with a third gate length on the first side of the substrate, and a fourth gate with a fourth gate length on the second side of the substrate. The second gate length is different than the fourth gate length, and the second dual gate transistor is coupled in series with the first dual gate transistor in the RFIC switch multi-finger transistor.
