Abstract
Mechanisms for adjusting atoms of an Intelligent Reflective Surface (IRS) are provided. A method is performed by a controller configured to control an IRS comprising an array of atoms, each having an individually adjustable phase shift and gain. At least some of the atoms are provided with a measurement sensor. The method comprises obtaining, from the measurement sensors, measurements of received power of a signal transmitted from a user equipment and received by the atoms and determining, by a gradient in received power between two of the measurement sensors is larger than a threshold value, that the user equipment is in near-field of the IRS. The method comprises, as a result thereof, adjusting the phase shift of a first subset of the atoms for reflection at the IRS of subsequent communication between a network node and the user equipment when the user equipment is in the near-field of the IRS.
