摘要
There is provided mechanisms for determining an electrical phase relation between antenna elements in an antenna array. A method is performed by a radio transceiver device. The method comprises obtaining measurements of the radio signal as received in two receive beams covering a given angular sector. The receive beams have different complex beam patterns. The method comprises estimating the angle of arrival of the radio signal for at least one polarization port of each of the receive beams using the measurements in the two receive beams. The method comprises determining, from the angle of arrival estimated for each polarization port, an electrical phase relation between antenna elements in the antenna array that corresponds to the estimated angle of arrival.
