One of the core visions for 6G (IMT-2030) is "Ubiquitous Connectivity," aiming to overcome the coverage limitations of current Terrestrial Networks in remote, maritime, and aerial environments. Non-Terrestrial Networks (NTN), particularly Low Earth Orbit (LEO) satellite communications, are considered a key technology to achieve this vision.
However, directly applying 5G protocols to satellites presents significant technical challenges, such as long propagation delays due to "high" orbits and frequent handovers caused by "fast" satellite speeds.
This presentation will use the 3GPP's (the global mobile communication standards body) process of integrating NTN into 5G-Advanced and future 6G standards as a case study. It will explore, in an accessible way, how the standards organization "identifies problems" (e.g., Timing Advance (TA) mechanism failure, handover storms) and "solves them" through protocol modifications and evolution (e.g., Open-loop TA, RACH-less Handover).
This talk will provide the audience with a glimpse into the 6G standardization process and the pivotal role NTN will play in the future of global communications.
