1. A method of operating a transmitter node configured to communicate with one or more receiver nodes using 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 spatial direction into which incident signals are selectively reflected by the RRD, the method comprising:
repeatedly transmitting reference signals towards the RRD at one or more transmit periods, and
setting the one or more transmit periods based on a re-configuration timing of the RRD, the re-configuration timing defining a dwell time of the RRD for providing each one of the multiple spatial filters, to thereby counteract a change of one or more receive periods of the reference signals at at least one receiver node of the one or more receiver nodes caused by the re-configuration timing.
