Abstract
Energy efficiency has emerged as one of the crucial pillars for communication networks, driven by increasing operational costs, environmental impacts, and stringent sustainability objectives. As data traffic continues to increase, and with it network expansion, the reduction of energy consumption in the radio access network (RAN) is of crucial importance in order to save significant costs for network operators in addition to responsible use of resources. Cell Discontinuous Transmission and Reception (cell DTX/DRX) is a proven efficient method for energy saving introduced in 3GPP NR Release 18. With cell DTX/DRX the energy consumption in 5G-Advanced networks is significantly reduced by allowing base stations to switch to sleep mode efficiently during inactive periods. Focusing on cell DTX, this paper proposes adaptive algorithms to dynamically optimize the activation and deactivation mechanism based on traffic load. In addition, this paper proposes algorithms to adapt the on-duration of cell DTX cycles depending on traffic load. The simulation results indicate that our proposed adaptive algorithms significantly reduce latency and signaling overhead while achieving substantial energy savings of up to 31%.
