AI Technical Summary

Problems solved by technology

[0003] The fifth generation of mobile communication technology (5G) provides reliable global services and large-scale connectivity to the world, but similar access point problems still exist, resulting in a lack of network coverage in nearly half of the world

However, the current 3GPP research on satellites is limited to the low-orbit satellite access technology similar to the ground mobile communication protocol, and has not carried out research and standard formulation work on high-throughput satellite access.
