Abstract: A communication arrangement, a method for the operation thereof and a computer program including instructions causing a computer to perform the method for the operation of the communication arrangement are disclosed. The communication arrangement includes one or more digitally controllable scatterers, DCSs, an assignment circuitry and a DCS control circuitry. The assignment circuitry is configured to assign a respective base phase shift pattern to each of the one or more DCSs. The DCS control circuitry is configured to operate, during a sequence of time intervals, each DCS of the one or more DCSs to provide a respective sequence of phase shift patterns that is obtained by applying, during each time interval of the sequence of time intervals, a respective additional phase shift from a sequence of additional phase shifts for the respective DCS to the base phase shift pattern assigned to the respective DCS.

Abstract: A radio channel may comprise a first component between two devices, and second and third components via the controllable scatterer. First reference signal(s) may be transmitted with the controllable scatterer configured to alter a propagation of signals such that influence of the second and third components of the radio channel is mitigated. Second reference signal(s) may be transmitted with the controllable scatterer configured to alter a propagation of signals such that influence of the second and third components of the radio channel is increased. An estimate of the first component may be determined based on the first reference signal(s) and an estimate of the third component may be determined based on the second reference signal(s) and a pre-computed estimate of the second component.

Abstract: A receiving network node includes a first antenna array, one or more radio frequency components, one or more configurable loads, a switch, and a first control circuit. The first control circuit obtains instruction data for configuring the first antenna array from a transmit-receive mode to a scattering mode. The first control circuit configures the one or more configurable loads based on the instruction data to scatter a first beam of a radio frequency signal sent by a transmitting network node located in a first cell to a first user device located in a second cell. The first beam is scattered by the configured first antenna array. The first control circuit controls the switch to change a coupling of one or more antennas from the radio frequency components to the configured one or more configurable loads, and sets the radio frequency components to an idle mode for power-efficient cooperative communication.
