Document Type and Number:
WIPO Patent Application WO/2022/130821
Kind Code:
A1
Abstract:
The objective of the present disclosure is to provide a radio communication device, a method for a radio communication device, and a program with which it is possible to perform calibration of an antenna easily. A radio communication device (11) according to the present disclosure comprises: a calibration control unit (111) that performs DL control to transmit a calibration downlink (DL) signal from an antenna other than one of a plurality of antennas DA and to receive a calibration DL signal by the one antenna, and UL control to transmit a calibration uplink (UL) signal from the one antenna and to receive a calibration UL signal by the antenna other than the one antenna; a calibration coefficient calculating unit (112) that calculates a calibration coefficient on the basis of a DL channel coefficient of a transmitter and a UL channel coefficient of a receiver that have been calculated on the basis of the calibration DL signal transmitted and the calibration DL signal received in the DL control and the calibration UL signal transmitted and the calibration UL signal received in the UL control; and a calibration applying unit (113) that adjusts the phase and amplitude of a radio DL signal on the basis of the calibration coefficient.
