Increased network wide energy consumption is a paramount challenge that hinders wide scale ultra-dense networks (UDNs) deployments. While several energy saving (ES) enhancement schemes have been proposed recently, these schemes have one common tenancy. They operate in reactive mode, i.e., to increase ES, cells are switched ON/OFF reactively in response to changing cell loads. Though, significant ES gains have been reported for such ON/OFF schemes, the inherent reactiveness of these ES schemes limits their ability to meet the extremely low latency and high QoS expected from future cellular networks vis-a-vis 5G and beyond. To address this challenge, in this paper we propose a novel user mobility prediction based autonomous proactive energy saving (AURORA) framework for future UDN. Instead of observing changes in cell loads passively and then reacting to them, AURORA uses past hand …
