The role of NTN in 6G

As its name implies, a Non Terrestrial Network comprises network infrastructure overhead in the form of either HAPS (High Altitude Platform Stations) or Drones and Unmanned Aerial Vehicle. Such technology brings about a number of advantages including: • Extending coverage to locations without any terrestrial coverage - in addition to providing connectivity to those rural communities with currently no or little access to the Internet, industries operating in remote areas such as mining, oil and gas exploration. • Situation Awareness supporting Mission critical services - natural disasters such as earthquakes or tsunamis often render traditional network infrastructure inoperable at the most critical time. NTN can be used to support: 1) Medical aid to search, 2) Rescue operations, 3) intelligence gathering and data mining. • Providing reliability and resilience - one of the three pillars of the 5G system is Enhanced Mobile Broadband and this called upon networks to not only provide super-fast connections but for these connections to be available whenever and wherever we go. The following talk/technical will present to cover the above challenges of NTN towards 6G. Energy efficiency: The network performance and power consumption in the mobile networks are unimaginably complicated, involving intra/inter networks deployment and operation modes, the efficiency of media accessing mechanisms, processing of baseband signal and quality of analogue signal and RF devices and antenna efficiency. Future wireless system are expected to achieve low energy consumption for different network components, optimize network resource utilization, and provide quality network services with intelligent and energy-efficient solutions. Data Analytics: The effective utilization of the network resources improves the system performance and also saves the energy used for mobile service. The utilization efficiency depends on the accuracy of the geo-temporal user behavior and services models and predictions derived from the location, mobility, historic network deployment, and traffic record. Privacy and Security: Strengthening people's trustfulness and enhancing secure performance is especially the key point for situation awareness and reliability/resilience communication. Efficient security barriers become of paramount importance in the expanding cellular (or 6G) network. Meanwhile, as the extending coverage in future communication, the confidence mechanism of energy-sparse, resource-constrained communication networks will be the most important aspect of security and privacy considerations.
