The method includes predicting traffic data amount of the at least two radio access technology (RAT) systems in a set first sharing period according to history traffic data of the at least two RAT systems and allocating spectrum resources in the first sharing period to the at least two RAT systems respectively according to the predicted traffic data amount. Based on the solutions provided by embodiments according to the present application, the utilization rate of spectrum resources can be effectively increased, and the user's traffic perception can be improved.

Abstract: A method for recognizing an identity and a gesture based on radar signals includes: reading a radar echo signal reflected by various gestures of a tester and received by a radar sensor; frequency-mixing the radar echo signal with a radar transmission signal; after filtering and centralizing a frequency-mixed signal, training and obtaining a neural network capable of identity verification and a neural network capable of gesture recognition; in a real-time detection process, verifying an identity of a user; and if the identity is verified, determining that a gesture of the user is valid; verifying the gesture of the user and executing a corresponding operation according to correspondence between the gesture of the user and an operation. It can be determined by the method whether the gesture belongs to the corresponding user and whether the operation corresponding to the gesture is performed according to the determined result.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may transmit, to a network entity, a first signal including a request to update a resolution of a phase shifting operation associated with beam-based communications. The UE may receive, from the network entity, a second signal approving the request. The UE may communicate using a beam according to an updated resolution of the phase shifting operation based on the second signal approving the request. Additionally, or alternatively, the UE may transmit a first signal including a request to suspend a beam refinement process based on the resolution of the phase shifting operation. The UE may receive a second signal approving the request to suspend the beam refinement process. The UE may communicate with the network entity using a beam based on suspending further beam refinement in response to the second signal.

Abstract: Technologies related to generating diverse electronic summary documents for a webpage are described herein. A sequence of tokens is extracted from the webpage, and the sequence of tokens is provided to several computer-implemented models. The computer-implemented models output respective sets of candidate assets based upon the sequence of tokens, where the candidate assets are potentially included in an electronic summary document for the webpage. Subsequently, a user query is received, and at least one candidate asset from the candidate assets are selected for inclusion in the electronic summary document based upon the query. Thus, different electronic summary documents can be generated for the webpage when different queries are received.

Abstract: An ultrasonic method and system for simultaneously measuring lubrication film thickness and liner wear of sliding bearings. The method includes: installing an ultrasonic sensor on a bearing bush; sending, by a processor, signals to an ultrasonic pulser-receiver to generate voltage pulses to excite the ultrasonic sensor to generate ultrasonic pulses; collecting an echo signal of an unworn liner-air interface as a reference signal Ba(f); collecting an echo signal of worn liner-lubrication film interface as to-be-measured signal Bow(f); obtaining an amplitude spectrum |Ba(f)| and a phase spectrum ?Baof Ba(f), an amplitude spectrum |Bow(f)| and a phase spectrum ?Bow(f) of Bow(f) by FFT; calculating an amplitude spectrum |Rw(f)|, and a phase spectrum ?Rw(f) of a reflection coefficient; based on |Rw(f)|, calculating lubrication film thickness d via a resonance model or a spring model; and based on ?Rw(f), calculating liner worn thickness via wear model under different film thicknesses.
