Abstract: One or more embodiments of the present description provide a method and device for risk prediction of thermal runaway in LIB. The method includes: acquiring knowledge of a mechanism for thermal runaway in LIB; describing an evolution process of thermal runaway in LIB by adopting a fault tree; mapping a fault tree structure to a dynamic Bayesian network model for thermal runaway in LIB to obtain quantitative results of a risk of thermal runaway in LIB; and taking the quantitative results of a dynamic Bayesian network as inputs of a machine learning model to obtain prediction results of the risk of thermal runaway. By using the method in the present embodiment, an evolution trend of battery thermal runaway can be predicted by fusing multiple thermal runaway causes and multi-source data, and thus, the prediction results are relatively accurate.

Abstract: There is provided mechanisms for controlling transmission from an antenna panel. The method is performed by a network apparatus. A method comprises performing time-domain beamformed communication with terminal devices served by the network apparatus using the antenna panel split into N>1 subpanels. Each subpanel has two input ports and is fed, via the input ports, by signals and configured to generate beams by application of antenna element weights to its antenna elements. The subpanels are at least phase-wise synchronized with each other. When one and the same signal is fed into the input ports of all the subpanels, signals as transmitted from the subpanels add up coherently to represent a 1-layer transmission by a time reference being shared between the subpanels.

Abstract: The present disclosure relates to an AC/DC closed-loop current sensor, including a magnetism gathering iron core, a TMR chip, a signal processing circuit, a signal generator, and a feedback coil. The TMR chip is arranged at an air gap of the magnetism gathering iron core and connected to the signal processing circuit. The signal processing circuit is connected to the signal generator. The feedback coil is wound around the magnetism gathering iron core and connected to the signal generator. The signal processing circuit is configured to select from the induced signal of the TMR chip and make an amplification to obtain a current signal component and send the current signal component to the signal generator. The signal generator is configured to adjust a current output to the feedback coil based on the current signal component, and output a measurement result of the selected current signal component.

Abstract: A method for time-domain allocation of radio resources in a communication system using beamforming comprises obtaining of a list of wireless devices to be served. Subcarriers and beam directions of a multi-directional beamform are allocated to wireless devices of the list. The beam direction for each wireless device covers a position of that wireless device. The number of allocable subcarriers is limited to fulfil a beam-forming power constraint. This beam-forming power constraint is that the total power of allocated subcarriers, when each allocated subcarrier provides a same effective isotropic radiated power density for a wireless device as would be provided by a single-directional beamform, is within a predetermined power budget.
