1. A method for establishing a direct communication using an unmanned aerial vehicle (UAV) with a reconfiguration intelligent surface (RIS), the method comprising:
configuring RIS parameters using an optimization algorithm based on compensating for undesired oscillations of a position and an orientation associated with the UAV, the undesired oscillations of the position and the orientation associated with the UAV representing an unknown position and an unknown orientation of the UAV during an optimization time; and
steering, based on the RIS parameters and by the RIS of the UAV, a signal reflection associated with a signal beam to a target area, wherein the signal beam is from a transmitter.
