Abstract

The invention provides a satellite mobile communication method fused with a 5G network, and the method is characterized by comprising the following steps: carrying out the modeling of a satellite mobile communication scene, and carrying out the quantitative description of the system composition, a network structure, a communication link, a transmission system, and a working process; establishing high and low frequency networking; establishing satellite-ground cooperative cognitive wireless communication in a dynamic spectrum environment; performing high-dynamic compensation on Doppler frequency shift in mobile satellite communication; and realizing multi-user non-orthogonal multiple access in a mobile satellite communication environment. The method has the beneficial effects that the system effectively utilizes various spectrum resources to improve the data transmission rate and the system capacity; idle unlicensed spectrum is utilized by the system, and the problem of spectrum shortage is solved; the 5G air interface waveform is optimized to enable the 5G air interface waveform to adapt to high dynamic characteristics in a satellite communication scene; the spectrum utilization rate and the system capacity are effectively improved; the problems that a satellite mobile communication system is special in topology, difficult in routing and large in user service end-to-end time delay are effectively solved.

Description

technical field [0001] The present invention relates to the field of network and mobile communication technologies, in particular to a satellite mobile communication method integrated with a 5G network. Background technique [0002] Satellite mobile communication refers to referring to the transmission technical standards of terrestrial mobile communication, fully integrating with land cellular mobile communication, providing "backhaul" data transmission or direct user access, so as to achieve global coverage of mobile communication. Nowadays, the advantages of satellite mobile communication have attracted widespread attention in the industry. Since ground mobile communication systems cannot be deployed in remote areas, and satellite communication itself has a large coverage area, 5G key technologies are applied to satellite communication to realize satellite mobile integrated with 5G. Communication can provide high-speed communication services for remote areas. [0003] At...
