More Capacity and Less Power: How 5G NR Can Reduce Network Energy Consumption
2019 IEEE 89th Vehicular Technology Conference (VTC2019-Spring), 2019Co-Authors: Pal Frenger, Richard TanoAbstract:In this paper we compare the energy consumption of the 3GPP standards 5G New Radio (NR) and Long-Term Evolution (LTE). We show that the energy consumption in an idle network (without User Plane Traffic) can be up to 9 times lower for an NR stand-alone network compared to an LTE network. The network energy consumption in low or no Traffic scenarios is a significant part of the operator OPEX in low Traffic areas [1], such as in extreme rural scenarios, and here NR has a clear advantage compared to LTE. To evaluate the energy performance advantage of NR when we have very high Traffic, such as in Super-Dense Urban and Urban scenarios, we perform system evaluations. We show that if we increase capacity in an existing LTE network with additional NR micro cells compared to using additional LTE cells, the reduction in network energy consumption is close to 50 percent. If we also upgrade the LTE cells in the macro coverage layer to NR a total energy reduction of up to 70 percent is achievable.

Assessment of Alternatives for Reducing Energy Consumption in Multi-RAT Scenarios
2014 IEEE 79th Vehicular Technology Conference (VTC Spring), 2014Co-Authors: Pal Frenger, Marten EricsonAbstract:Modern radio base stations (RBSs) typically consist of components such as radio units (RUs) and digital units (DUs) that are capable of supporting multiple radio access technologies (RATs) at the same time. This enables several different possible configurations of a multi-RAT site and in this paper we assess the energy performance of some promising configurations. We start by evaluating an LTE-only network and conclude that with Traffic according to predictions for 2015 the average cell will be idle 95% of the time and the additional energy consumption due to the User Plane Traffic is only 1.4%. We also show that even a significant future Traffic increase will only have a minor impact on the energy consumption. We further show in this paper that a multi-RAT RBS where the RATs share the digital unit (PA) have the potential to reduce the site energy consumption with 40% compared to a multi-RAT RBS with separate PAs for each RAT. For operators with multiple RATs on the same site but using separate PAs per RAT, it is still possible to reduce energy consumption by utilizing load balancing between the RATs. This study shows that a potential energy reduction in the order of 30% is possible by utilizing load balancing between HS and LTE.

towards performance improvement of User Plane Traffic in wireless system security aspects
Consumer Communications and Networking Conference, 2020Co-Authors: Rajadurai Rajavelsamy, Hilam Patel, Siva Naga Kumar AAbstract:Security practices are one of the sources of power consumption and introduces latency. In this short paper, we present the identified overhead in terms of power consumption and latency, introduced by applying security at multiple layers in emerging wireless networks, particularly for the 5G User data communication. Novel security mechanism is proposed for 5G systems for power efficient and low latency User data communication. The proposed mechanism enables the battery charge to last around 5mins longer and reduces latency by 4%, for 10GB data transfer.

a service oriented approach on securing User Plane Traffic between ngn security domains
Wireless Communications and Networking Conference, 2010Co-Authors: Ronald MarxAbstract:In today's Next Generation Networks (NGN) many services are residing that all make different security demands on the inter-domain communication. In this paper a concept will be presented that is based on Network Domain Security (NDS) specification and extends it in such a way, that multiple tunnels - depending on the security needs of the involved endpoints - can be established. The concept hereby focuses on the inter-domain interface between two security gateways (SEG) of different domains, where potential external attackers are expected. The proposed concept efficiently secures, besides control Plane Traffic, also User data with the existing NDS approach. Finally, the concept has been implemented as proof of concept.
