The present disclosure relates to channel estimation, at a receiving device of a communication system employing a (re)configurable surface. The channel estimation includes beamforming search to obtain trained reflection coefficients of the configurable surface and an angle of arrival, AoA, of the signals at the receiving device. Then, based on the configurable surface and the obtained AoA at the receiving device, reflection coefficients of the configurable surface are derived for an ideal channel portion between the transmitting device and the configurable surface. According to a relation between the trained reflection coefficients and the estimated reflection coefficients, the estimation of the characteristics of a channel between the transmitting device and the configurable surface is performed. The channel estimation may be employed in user mobility tracking.
