Resource allocation method and system for air-space-ground integrated network

Abstract

Embodiments of the present invention provide a resource allocation method and system for an air-space-ground integrated network. The method includes: dividing each time period to be allocated into a plurality of time slots; for each time slot, according to the The transmission signal-to-noise ratio of each relay, and the transmission signal-to-noise ratio of each relay to the satellite, obtain the transmission rate of each device passing through each relay and reaching the satellite; The allocation scheme for communication through each relay, combined with the transmission rate, obtains the average throughput of the system in all time slots in the time period; when the average throughput of the system is maximized, for each time slot, the equipment is connected through the relay, Relay movement trajectory and transmit power allocation scheme, and allocate. The relay can dynamically move to the smart device, reduce the transmit power consumption of the smart device, prolong the battery life, realize the flexible deployment of the relay and the dynamic coverage of the smart device, and effectively improve the maximum throughput of the system.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a resource allocation method and system for an air-space-ground integrated network. Background technique [0002] With the rapid development of terrestrial communication systems in recent years, users can experience higher data rates, wider range of connections, and lower latency network access. However, this does not mean that all users on the ground can enjoy this high-quality network service at any time. As we all know, due to the lack of network resources and effective coverage, the development of traditional terrestrial communication technology is difficult to provide fair and high-quality services for terrestrial user equipment, especially for equipment nodes deployed in remote areas such as deserts, oceans, and forests. The deployment cost of the terrestrial high-speed broadband infrastructure is lacking, so that these device nodes will still suffer from the problems...
