Abstract
A method is proposed for operating a re-configurable reflective device, RRD, the RRD being re-configurable to provide multiple spatial filters, each one of the multiple spatial filters being associated with a respective input spatial direction from which incident signals on a data radio channel are accepted and with a respective output spatial direction into which the incident signals are reflected by the RRD. The method comprises: receiving, by the RRD from a first communication node, CN1, on a positioning radio channel different from the data radio channel, a CN1 reference signal, determining, by the RRD, an estimated CN1 angle of arrival of the CN1 reference signal, and reconfiguring the RRD based on the estimated CN1 angle of arrival.
