Abstract

The present application relates to methods for calibrating an array antenna (301) of a terminal (300) in a MIMO communication system (100). The method comprises: communicating, to a base station (200) of the MIMO communication system (100), a calibration capability indication from the terminal (300) indicative of a capability of the terminal (300) of calibrating receivers and transmitters for beam correspondence; communicating, from the base station (200) of the MIMO communication system (100) to the terminal (300), a control message indicative of radio resources; using the radio resources: calibrating receivers and transmitters of the terminal (300) for beam correspondence by performing over-the-air measurements of mutual coupling between antennas (310-312) of the array antenna (301).
