Abstract: Provided is a method performed by a user equipment (UE) in a wireless communication system. The method includes performing communication with a base station based on a full-duplex mode, transmitting, to the base station, a first message for requesting a duration for calibration of a circuit for analog self-interference cancellation (SIC), receiving, from the base station, a second message for allocating the duration, and performing the calibration of the circuit during the duration. Herein, during the duration, the UE is controlled to operate based on a half-duplex mode.

Abstract: A deflection yoke capable of damping the leaking magnetic fields leaking to the front of the screen is disclosed. The characteristic feature of the deflection yoke includes: two pairs of ferrite cores opposingly facingly disposed on the flange portion of the beam outgoing side of the deflection yoke; and coils extended from the horizontal deflection coil and wound on the ferrite cores in such a manner as to offset all the magnetic fields other than the main horizontal deflection magnetic field.
