Cell-free massive multiple-input multiple-output (CF mMIMO) systems areexpected to provide faster and more robust connections to user equipments (UEs)by cooperation of a massive number of distributed access points, and to be oneof the key technologies for beyond 5G (B5G). In B5G, energy efficiency (EE) isone of the most important key indicators because various kinds of devicesconnect to the network and communicate with each other. While previouslyproposed transmit power control methods in CF mMIMO systems have aimed tomaximize spectral efficiency or total EE, we evaluate in this paper a differentapproach for maximizing the minimum EE among all UEs. We show that thisalgorithm can provide the optimum solution in polynomial time, and demonstratewith simulations the improved minimum EE compared to conventional methods.
