JOINT ACTIVE RIS CONFIGURATION AND USER POWER CONTROL FOR LOCALIZATION: A NEUROEVOLUTION-BASED APPROACH

This paper studies user localization aided by a Reconfigurable Intelligent Surface (RIS). A feedback link from the Base Station (BS) to the user is adopted to enable dynamic power control of the user pilot transmissions in the uplink. A novel multi-agent algorithm for the joint control of the RIS ph…
