1. A method of operating an access node of a communications network, the access node communicating with a wireless communication device via a reconfigurable repeater 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 carrier are accepted and with a respective output spatial direction into which incident signals are reflected or amplified by the RRD, the method comprising:
in response to a need to facilitate an angle-of-arrival measurement at the RRD based on reference signals transmitted by the wireless communication device, providing, to the wireless communication device, a configuration of a reference-signal transmission comprising the reference signals, the reference-signal transmission being on an auxiliary carrier different from the data carrier.
