Abstract: According to an aspect, there is provided an apparatus for performing the following. The apparatus maintains, in at least one memory, information on a reference incidence direction and reference configuration information defining a plurality of configurations of a plurality of tunable load impedance circuits of a tunable reflective array of a reconfigurable intelligent surface or a subpanel thereof for the reference incidence direction. The apparatus measures an incidence direction from which electromagnetic waves are received by the reconfigurable intelligent surface. The apparatus calculates, based on the reference incidence direction, the measured incidence direction and the reference configuration information, corrected configuration information defining a plurality of corrected configurations for the measured incidence direction. Finally, the apparatus configures the plurality of tunable load impedance circuits according to a corrected configuration.

Abstract: Disclosed is a method including transmitting one or more reference signals to one or more user devices; performing preliminary sensing over a sensing area of interest based at least partly on the one or more reference signals; allocating, based at least partly on the preliminary sensing, radio resources for performing sensing with a higher resolution than a resolution of the preliminary sensing; and performing the sensing with the higher resolution over the sensing area of interest by using the allocated radio resources.
