Abstract
A method of operating a transmitter node () configured to communicate with one or more receiver nodes (-) using a re-configurable reflective device. RRD (), is provided. The RRD () is 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 includes repeatedly transmitting reference signals () towards the RRD () at one or more transmit periods (-). The method also includes 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 ().
