Abstract: The present application discloses a method and a device for user grouping and resource allocation in a NOMA-MEC system. The hybrid deep reinforcement learning algorithm proposed in the present application solves the hybrid problem of deep reinforcement learning that is difficult to deal with both discrete and continuous action spaces by using DDPG to optimize continuous actions and DQN to optimize discrete actions. Specifically, the algorithm determines a bandwidth allocation, an offloading decision, and a sub-channel allocation (user grouping) of the user device based on the user's channel state, in order to maximize the ratio of the computation rate to the consumed power of the system. The algorithm is well adapted to the dynamic characteristics of the environment and effectively improves the energy efficiency and spectrum resource utilization of the system.

Abstract: This application provides an information feedback method and a related apparatus. In the method, a first apparatus sends, to a second apparatus, a first frame that carries a first field used to perform channel estimation, and the first apparatus receives a first feedback frame from the second apparatus. The first feedback frame includes channel state information CSI, the CSI is CSI from the first apparatus to the second apparatus, the CSI is obtained by the second apparatus by performing channel estimation based on the received first field and a second field, and the second field is not the first field.

Abstract: An inductor has a main magnet core, a coil mounted around the main magnet core, and a residual magnet encapsulating the main magnet core and partially encapsulating the coil. The main magnet core is made of a main magnet core powder containing amorphous iron base material and nickel base material powders. The residual magnet is made of a residual magnet powder containing a main magnet powder and a soft magnet powder including an iron-silicon-chromium alloy powder and a carbonyl iron powder. Thus, through a low-loss feature of the amorphous iron base material and nickel base material powders, a loss of the main magnet core is reduced. Furthermore, a magnetic permeability of the residual magnet matches a magnetic permeability of the main magnet core. A magnetic leakage is further avoided, and the alternating current resistance is reduced. A quality factor and a conversion efficiency are enhanced.

Abstract: A circuit design includes a flexible film, an electrode pattern, and a connecting circuit. The flexible film has a visible area and a bending area and includes an external conductive connection. The electrode pattern is disposed in the visible area of the flexible film. The connecting circuit is electrically connected to the electrode pattern and disposed in the bending area of the flexible film. The bending area has a first portion and a second portion. The first portion is located between the visible area and the second portion. A width of one end of the second portion connected to the first portion is smaller than a width of the first portion. The external conductive connection is electrically connected to the connecting circuit and located at another end of the second portion.

Abstract: A touch display module has plural sensors and includes an integrated frame, a backlight module, a thin film transistor substrate, a color filter, and a polarizer. The integrated frame has a bottom plate portion and a side plate portion, and the side plate portion stands on the bottom plate portion. The backlight module is disposed on the bottom plate portion. The thin film transistor substrate is disposed on the backlight module. The color filter is disposed on the thin film transistor substrate. The polarizer is disposed on the color filter. One surface of the polarizer is an outer surface of the touch display module. The thin film transistor substrate and/or the color filter is connected to the side plate portion of the integrated frame. Therefore, by using the integrated frame to integrate required components into one mechanical part, the touch display module has thinner thickness and lighter weight.
