Abstract: Provided are a charging/discharging apparatus, an operation method of the charging/discharging apparatus, and a display apparatus including the charging/discharging apparatus. The charging/discharging apparatus includes a charging unit comprising circuitry configured to charge a battery pack, and a direct current (DC)-DC converter configured to convert a battery voltage of the battery pack into a voltage for operating the display apparatus, wherein, in a first mode based on an alternating current (AC) power source being applied to the display apparatus, the charging/discharging apparatus charges the battery pack with a battery voltage less than a secondary voltage generated by the display apparatus from the AC power source through the charging unit, and in a second mode based on the AC power source not being applied to the display apparatus, the charging/discharging apparatus delivers the battery voltage of the battery pack to the display apparatus.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. According to an embodiment of the present invention, a method for controlling a base station supporting a multi-antenna system may comprise the steps of: generating a plurality of test signals for a plurality of antennas in a modem; controlling the plurality of generated test signals to be fed back to the modem through a plurality of feedback paths which are formed for the plurality of antennas, respectively, and do not affect each other; and identifying the plurality of test signals fed back to the modem, on the basis of the plurality of generated test signals.
