AI Technical Summary
Technical Problem
The question of how terminal devices can access the network through non-terrestrial networks in narrowband IoT systems, especially the issue of coexistence with low Earth orbit satellite services in the same frequency band.
Method used
The random access procedure is performed using a first frame structure, which includes periodically configured first resources and/or second resources. The first resources include multiple consecutive uplink time domain units, and the second resources include multiple consecutive downlink time domain units.
Benefits of technology
This enables terminal equipment and low Earth orbit satellite services to coexist in the same frequency band, improving the frequency band utilization efficiency and access efficiency of the communication system.
