Key technologies and evolution of 5G non-terrestrial network
Published 2022-03-01“…Non-terrestrial network (NTN) in 5G system is expected to provide communication services via near-earth space access and satellite access, which means 5G network has expanded its service area from land to space.Standardization status and key technolgies of 5G 3GPP Release 17 NTN were presented, including key differences compared 5G TN, especially in network architecture, time and frequency synchronization, HARQ, and mobility management etc.Moreover, the main candidate techniques in 3GPP Release 18 NTN and beyond were explored, aiming to outline a vision for NTN evolution.Based on the analysis of 5G NTN and its evolution, it was observed that the integration of TN and NTN would be an obvious technique trend, which paved a way to a unified system applied for space, land and sea.…”

Endogenous Security for the Space-Integrated-Ground Information Network in 6G
Published 2023-06-01“…The space-integrated-ground information network in 6G is facing security challenges due to its characteristics, such as the high exposure of the network, high-speed movement of nodes, limited computing resources.Moreover, new security issues are certainly introduced in the development of new architectures, new applications, new technologies and so on.It is urgent to propose new universal security theories to overcome safety and security threats by the integrated solutions.For this purpose, this paper first expounded the cyberspace endogenous security and proposed its endogenous security architecture.Then, under the guidance of the cyberspace endogenous security theory, the relevant security theory and practice norms were respectively discussed for onboard systems, 6G ground mobile networks, and satellite-ground links.Finally, the authentication and encryption mechanism of the communication and security integration from the aspects of security authentication and high security communication encryption, and the integration of traditional security technology and endogenous security were analyzed.…”
