1. A method of operating a first communication node (CN) wherein the first CN is configured for controlling a first coverage enhancing device (CED) wherein the first CED is reconfigurable to provide multiple spatial filterings, each one of the multiple spatial filterings 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 comprising
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.
