AI Technical Summary

Technical Problem

In non-terrestrial networks, satellite uplink scheduling latency is relatively high, which cannot meet the service packet latency budget of user equipment, resulting in problems such as voice stuttering, video screen tearing, and control command response delays, thus affecting the service experience.

Method used

By obtaining the uplink service latency requirements of the target user equipment, its scheduling cycle is shortened, and cycle configuration information is generated based on the cycle offset, enabling the target user equipment to transmit signals with the satellite. By utilizing the overlap of cycle offsets in the same waveband and the reuse of frequency domain resources, uplink scheduling is optimized.

Benefits of technology

It reduced uplink scheduling latency, met uplink service latency requirements, improved service experience, and increased beam utilization.

Abstract

The application provides a non-ground network-based uplink scheduling method, an electronic device and a storage medium. The method comprises the following steps: obtaining an uplink service time delay requirement of a target user equipment; performing reduction processing on a scheduling period of the target user equipment according to the uplink service time delay requirement, to obtain target period information; if there is a first user equipment in a target satellite wave position, obtaining a target period offset according to the target period information and a period offset of the first user equipment; generating period configuration information of the target user equipment according to the target period information and the target period offset; and sending the period configuration information to the target user equipment. The application reduces the scheduling period based on the uplink service time delay requirement, reduces the uplink scheduling time delay, meets the uplink service time delay requirement, improves the service experience, and realizes the multiplexing of the satellite uplink beam through the period offset overlap of the same wave position, thereby improving the beam utilization rate.
