From 5G to 6G non-terrestrial networks (NTN)

During the last few years, the development of non-terrestrial networks (NTN) has consistently taken leaps forward. 5G NTN standards are becoming mature, and after that, the attention will move towards 6G NTN.
The work on NTN started with 3GPP Release 15 and Release 16 by studying the NTN channel model, deployment scenarios, and minimum required adaptations for the existing 5G system to support NTNs.
Release 17 was the first official 3GPP release that supports NTN for FR1 and handheld devices. Release 18, in turn, targeted to enhance the capabilities of NTN operation for above 10 GHz frequency bands (FR2) for VSAT terminals.
Magister has been working within 3GPP throughout this process. We are happy to be able to share our competence in system simulations and help build the future of the SatCom industry through standardization – and there is still a lot to come.
The next phase on this development path is Release 19 that will enhance the NTN performance and use cases. The objective is to provide improved coverage and optimized capacity, multicast and broadcast services (MBS), regenerative payload, and support for Reduced Capability (RedCap) terminals:
After Release 19, the focus starts to shift towards 6G, which is expected to be a bigger leap.
3GPP has committed to developing 6G specifications: the studies for 6G in 3GPP are expected to start from Release 20 in 2025, after which begins the normative work for 6G in 3GPP on Release 21 in 2027.
6G NTN is an SNS JU project that aims to design and validate NTN’s key technical, regulatory, and standardization enablers for the integration of TN and NTN components into 6G. The objective is to build a unified TN and NTN system, with the design created for both environments from the start.
The ETSI conference “Non-Terrestrial Networks, a Native Component of 6G” held in April 2024 brought forward important viewpoints towards 6G NTN. The conference provided attendees the unique opportunity to come together and exchange with experts, network with peers, and visit the dedicated project posters all focusing on the topic of Non-Terrestrial Networks beyond 5G.
Magister has been actively involved in 5G NTN standardization work through several ESA-funded projects. One of our focus areas has been to provide system simulation support for NTN standardization needs.
Through all the projects of recent years, we have gained in-depth knowledge of 5G NTN development and simulative evaluation. We can utilize this knowledge in further helping our customers.
