Controlling a reconfigurable intelligent surface device

A base station, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the base station to:
• determine a control signal for a reconfigurable intelligent surface device to control a parameter of at least one element of a plurality of elements of the reconfigurable intelligent surface device, wherein the parameter comprises information indicating a phase angle;
• and
• transmit the control signal to the reconfigurable intelligent surface device to control the parameter of the at least one element of the reconfigurable intelligent surface device.

An apparatus for performing a network function, the apparatus comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the apparatus to:
• receive a control signal from a base station to control a parameter of at least one element of a plurality of elements of a reconfigurable intelligent surface device, wherein the parameter comprises information indicating a phase angle;
• and
• control the parameter of the at least one element of the reconfigurable intelligent surface device based on the control signal.
