Abstract
A method of operating a transmitter node (101) configured to communicate with one or more receiver nodes (102-104) using a re-configurable reflective device. RRD (109), is provided. The RRD (109) is re-configurable to provide multiple spatial filters, each one of the multiple spatial filters being associated with a respective spatial direction (351-353) into which incident signals are selectively reflected by the RRD (109). The method includes repeatedly transmitting reference signals (198) towards the RRD (109) at one or more transmit periods (551-554). The method also includes setting the one or more transmit periods (551-554) based on a re-configuration timing (510) of the RRD (109), the re-configuration timing (510) defining a dwell time (511-513) of the RRD (109) for providing each one of the multiple spatial filters, to thereby counteract a change of one or more receive periods (531) of the reference signals (198) at at least one receiver node (102) of the one or more receiver nodes (102-104) caused by the re-configuration timing (510).
