Abstract
There is provided mechanisms for OTA based estimation of phase accuracy of a first radio transceiver device. A method is performed by a controller. The method comprises obtaining, per each position in a sequence of positions of a second radio transceiver device relative the first radio transceiver device, a phase relation estimate between transceiver branches of the first radio transceiver device. Each phase relation estimate is obtained from measurements on a signal wirelessly transmitted between the first radio transceiver device and the second radio transceiver device. The method comprises estimating an average phase relation for at least one pair of the transceiver branches of the first radio transceiver device by averaging the obtained phase relation estimates over all the positions in the sequence of positions. The phase accuracy of the first radio transceiver device is represented by the average phase relation for the at least one pair of the transceiver branches.
