Abstract: A method of a terminal may comprise: receiving a first message including state information of a base station from the base station; identifying preliminary inactive state information included in the first message when the state information of the base station indicates a preliminary inactive state; and performing a cell selection based on the preliminary inactive state information.

Abstract: The present disclosure relates to a method of reducing a Peak to Average Power Ratio (PAPR) in a communication device, and more particularly, to a method of Crest Factor Reduction (CFR) processing of a signal in order to reduce a PAPR in a communication device such as a repeater. The communication device includes: a first CFR module configured generate a first processed signal by CFR processing an original signal; and a second CFR module configured generate a second processed signal by CFR processing the first processed signal, wherein the first processed signal is generated using a first sampling rate, and the second processed signal is generated using a second sampling rate. According to the disclosure, even a communication device with a low sampling rate may effectively remove a peak component of an input signal.

Abstract: A high temperature aging system includes a battery cell tray stack having a structure in which battery cell trays are stacked in multiple stages therein, one or more tray racks located inside a high temperature aging chamber and each including a grid-shaped storage space in which the battery cell tray stack is located, a stacker crane configured to transport the battery cell tray to the grid-shaped storage space, a thermal imaging camera installed on the stacker crane configured to acquire thermal image temperature data on the battery cell trays loaded in the grid-shaped storage space, and a controller configured to control a temperature inside the high temperature aging chamber on the basis of the thermal image temperature data.

Abstract: The present technology relates to a spatial address-based management system, and the management system includes a spatial address-related information reception part configured to receive spatial address-related data assigned to each of segments generated by dividing a workspace into a plurality of rows and columns, a controller configured to process the spatial address-related data received from the spatial address-related information reception part and transmit the processed data to a spatial address-related data storage part, and the spatial address-related data storage part configured to store the spatial address-related data transmitted from the controller as spatial address data, wherein the spatial address data includes information on a unique position of the spatial address, information on a workpiece that is placed at the spatial address, and information on attributes or properties of the spatial address.

Abstract: The present specification relates to an optical film including a transparent base; an anti-static primer layer provided on at least one surface of the transparent base, and including a binder resin including a sulfonic acid polyester acryl-based resin and an anti-static material; and a surface treatment coating layer provided on the anti-static primer layer, and a polarizing plate including the same.
