Featured Article, "Energy efficiency maximization for active RIS-aided integrated sensing and communication"
Research towards the 6th generation of mobile communications considers many new technologies. They include reconfigurable intelligent surfaces (RIS) as well as integrated sensing and communications (ISAC). The synergy of these two techniques can improve the reliability of data communications and simultaneously the accuracy of sensing. Energy efficiency is an important key performance indicator since the 5th generation of mobile communications. In the paper, the authors utilise the synergy of RIS and ISAC to improve the energy efficiency in multiple antenna downlink transmission. Active and passive RIS are compared and the gains compared to the state of the art are illustrated. View the full text here.
