Special Issue Information

Dear Colleagues,

In order to meet the continuously expanding application requirements of next-generation mobile communication in global-wide coverage, large-scale flexible access, and emergency communication, the satellite terrestrial integrated network, as one of the key technologies in future 6G, integrates satellite communication network and ground mobile network, towards deep integration in systems, technologies, and applications.

Due to significant differences in performance such as latency, reliability, throughput, and security in different communication systems, there are still many problems and challenges involved in the research of satellite terrestrial integrated networks in terms of architecture, key technologies, experimental platforms, technical standards, security, and future applications.

This Special Issue focuses on the technology, security, and applications of key satellite terrestrial networks in the next-generation communication system. We hope that the launch of this topic can introduce the latest research results of satellite terrestrial networks from different perspectives, to provide technical approaches and standard development references, inspiration, and reference for related fields of research and application, and jointly promote the 6G research and development process.

In this Special Issue, original research articles and reviews are welcome. Research areas may include, but are not limited to, the following:

  • Network Architecture of Satellite Terrestrial Networks;
  • Beam Hopping Management and Interference Coordination Technology in Satellite Terrestrial Networks;
  • Resource perception and intelligent scheduling technology in Satellite Terrestrial Networks;

Satellite communication is proposed to fulfill the ubiquitous coverage for next-generation wireless networks. Considering the propagation delay and path loss, low-earth orbit (LEO) satellites are widely adopted. However, since the beam boresight directions become close in quasi-earth-fixed cells (QEFC) scenarios at low elevation angles, the interference increases and causes low communication quality. This paper introduces the optimal beamwidth maximizing uplink coverage probability scheme for quasi-earth-fixed cells in LEO satellite communication systems. The proposed scheme dynamically adjusts the beamwidth to achieve max uplink coverage probability at different elevation angles. The simulation results show that the proposed scheme matches the exhaustive search method in different scenarios and target signal-to-interference-plus-noise ratios. Furthermore, the proposed scheme significantly mitigates interference and improves the uplink coverage probability. Compared with the 3GPP setting, the proposed scheme improves the uplink coverage probability by 0.93 at time 100 s, and compared with the three-color frequency reuse, the proposed scheme improves the uplink coverage probability by 0.195 at time 100 s. The dynamic beamwidth and boresight direction adjustments enable the satellite to maintain seamless and reliable communication services across a wide range of operating conditions, ultimately realizing the goal of ubiquitous communications in the QEFC LEO satellite system.

In this paper, we study the enhancement of channel transmission information by expanding the transmission channel in the frequency-hopping rate dimension in a communication system. This is achieved using the frequency-hopping spread spectrum (FHSS) without increasing communication resources, such as power and bandwidth. The anti-jamming capability of the original information is maintained during this process. The spectral characteristics of the extended signal for frequency-hopping (FH) transmission are investigated, a demodulation method based on carrier reconstruction is proposed, the bit error rate performance is simulated, and the capacity enhancement and anti-jamming ability of the extended signal for FH transmission are analyzed.

Leveraging technological advancements such as containers, microservices, and service mesh, cloud-native edge computing (CNEC) has become extensively discussed and applied in both academia and industry. The integration of mobile edge computing and communication is crucial for the future communication architecture in order to fully utilize distributed and fragmented communication resources and computing power. The potential for cloud-native integration can help merge mobile edge computing and communication, enhancing network flexibility and resource utilization. This paper investigates the implementation plan for extending cloud-native capabilities to integrated computing and communication (INCCOM) in the satellite–terrestrial network. We construct an experimental verification platform called ComEdge in a real-world setting. Subsequently, we analyze the architecture, functional characteristics, and deployment of the platform in a real-world environment. Furthermore, we explore the solution of deep reinforcement learning in the deployment of cloud-native core network and conduct a preliminary verification of the platform’s potential to enable artificial intelligence in a real production environment, which will provide guidance to both academic and industry sectors. Finally, we conduct an analysis on the challenges and opportunities encountered by the cloud-native INCCOM network system. Full article
