Abstract: A node in a wireless communication system and a method performed by the same are provided. The method includes obtaining information related to a channel between a user equipment (UE) and a base station, and extracting first feature information based on the information related to the channel between the UE and the base station, the first feature information being used to determine information of a location of the UE using an artificial intelligence (AI) model and/or to monitor whether the AI model needs to be updated.

Particularly, an uplink signal transmission method is provided, comprising: reporting parameters of signal transmission quality in a specific modulation mode; acquiring configuration parameters of an uplink physical channel and/or a physical signal; and transmitting an uplink signal according to the configuration parameters of the uplink physical channel and/or the physical signal.

Abstract: A method for preparing high-purity nickel-based superalloy includes the steps of: performing electron beam smelting on small cylinders in a first water-cooled copper crucible after preheating an electron gun, and converging the beam to the edge of one side of the ingot; turning on the electron gun again after completely solidifying the ingot, the electron beam spot uniformly and slowly scanning a surface of the ingot from a side opposite to a final beam converging area of the ingot to the final beam converging area of the ingot to ensure that the alloy at a position scanned by the electron beam spot is completely melted, and stopping scanning once scanning to the final converging area of the ingot; casting the molten alloy in the first water-cooled copper crucible to the second water-cooled copper crucible; taking out the refined nickel-base superalloy after cooling down the electron beam melting furnace.
