The method comprises at least one of a first group and a second group of steps. The first group of steps comprises collecting a first group of amplitude and phase differences between a first calibration signal and each of a first and a fourth reception signals and between a second calibration signal and each of a second and a third reception signals. The first group of steps further comprises estimating, based on the first group of amplitude and phase differences, a signal response characteristic difference between a calibration reception chain of the first transceiver and a calibration reception chain of the second transceiver for reference antenna reception calibration of the first transceiver with respect to the second transceiver."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for antenna calibration","description":"The present disclosure provides a method in a base station of a radio network for antenna calibration of a first transceiver of the base station with respect to a second transceiver.
