Satellite and Terrestrial Network Convergence

MediaTek believes that integrating satellite and terrestrial mobile networks to offer pervasive connectivity across the world will not only enable a new era of innovative digital services, but also significantly contribute to the United Nations Sustainable Development Goals. Compared with proprietary satellite communication technologies, 6G non-terrestrial network (NTN) technology based on a 3GPP open standard can leverage the economies of scale from the existing global mobile cellular ecosystem to bring satellite communication from a niche market to mainstream consumer and business markets leveraging common devices that switch between satellite and cellular networks for an always connected user experience.

MediaTek’s research has identified four major new technology areas for 6G that can further enhance NTN: efficient waveform design, enhanced mobility, massive satellite beamforming and cellular/satellite spectrum sharing. High level concepts and initial research results are provided in this white paper. More detailed system design and evaluation results will follow in future white papers.
