Small cell deployments and particularly femtocells provide an attractive, cheap and flexible solution for the increased traffic demand. However, the resulting dense networks are characterized by challenges, too, such as increased interference and resource allocation. In this paper, we propose ways to address these difficulties by combining hybrid access, sleep mode and a power control mechanism. Simulations show that the above mechanism leads to improved capacity and throughput for subscribers, along with improved energy efficiency, without compromising the non-subscribers performance.1 aBouras, Christos1 aDiles, Georgios1 aNtoutsos, Dimitrios  uhttp://telematics.upatras.gr/telematics/publications/sleep-mode-strategies-dense-small-cell-5g-networks
