    This SAT5G demonstration investigates the use of 5G New Radio (NR) over satellite links: harmonisation of user and control planes. In terms of 5G functionalities, SaT5G focuses on: PHY layer (downlink and uplink detection with Doppler), RACH design, timing advance, HARQ. Location: Oulu (Finland) Date: Q4-2019
  2. SaT5G will foster the implementation of solutions enabling the "plug and play" integration of satcom components into 5G networks. • To this aim, SaT5G will research and validate the key technology enablers through validation and demonstration in live 5G testbeds. • SaT5G impact is for the satellite industry to join the European initiative

    The aim of the paper is to consider feasibility of 5G new radio (NR) over satellite links also known as nonterrestrial networks (NTNs). Large propagation delay and Doppler frequency shift are challenges like is high peak-to-average power ratio (PAPR) of 5G NR signal because satellite systems would like to operate at very low-power amplifier back-off values.

    A pool of control plane nodes is also run, which manage the user sessions, consisting of SMF and policy control function (PCF). The user data traffic is serviced at user plane node slices, consisting of a UPF. Auxiliary core network functions are also deployed as VNFs, which are network exposure function (NEF) and network repository function (NRF).

    One of the SaT5G use cases corresponds to the delivery of 5G connectivity services to moving platforms such as aircraft via GEO/MEO satellite backhauling. With focus on this use case, this paper elaborates on the practical implementation and measurement results obtained within the 5G Aero testbed developed as part of the SaT5G project.

    Dec 1, 20235G user plane functions. In 5G networks, UPFs are the main network function of the user plane [1], [25]. They are the evolution of serving and packet gateways (SGW and PGW) in Evolved Packet Core (EPC) networks under the concept of CUPS. Their primary function is processing data plane packets between access and data networks (AN and DN).
  9. SaT5G Consortium 5G Demo THE SaT5G CONSORTIUM The SaT5G consortium is funded by the European Commission and brings together industry leaders across the ecosystem to promote the cost-effective "plug and play" integration of satellite technology into 5G networks. Satellite will be crucial to 5G networks to ensure security,
