Abstract
According to a first aspect, examples provide a method of operating a first communication node (CN), wherein the first CN is configured for controlling a first CED, wherein the first CED is reconfigurable to provide multiple spatial filterings, each one of the multiple spatial filtering being associated with a respective input spatial direction from which incident signals on a radio channel are accepted and with a respective output spatial direction into which the incident signals are transmitted by the first CED. The method comprises receiving, from a second CN on the radio channel, a first reference signal via a first propagation path and a second propagation path, wherein receiving the first reference signal via the first propagation path involves receiving a component of the reference signal via the first CED, measuring a first reception property of the first reference signal, and providing, to the first CED, a message for configuring the first CED to induce a first phase shift in the first propagation path. Further examples provide a further method of operating a first CN methods of operating a CED as well as respective first CNs, second CNs and CEDs.
