A flexible scheduling system and scheduling method for beam-hopping oriented wave position resources

Abstract

A beam-hopping beam-hopping flexible scheduling system and scheduling method for resources. A beam refers to the coverage area of ​​a beam-hopping beam on the surface of the earth in a specific direction, and its availability is subject to the allocation of time slots. The flexible wave position resource scheduling system includes: resource manager, processor, beam controller, transmitting antenna and receiving antenna. The resource manager completes the flexible wave position resource scheduling process according to the service access application signaling, and sends instructions to the receiving antenna And the beam controller inside the transmitting antenna controls the hopping timing of the beam hopping; sends scheduling information to the processor to ensure the synchronization of the transmitted data and the wave position. The flexible scheduling method of wave position resources, that is, the processing and control operation process of the resource manager, mainly includes three steps: determination of elastic wave positions, optimal allocation of resources, and jump control. Based on the high dynamics of user demand distribution and the shape variability of beam hopping, the present invention can effectively improve the utilization rate of beam hopping resources and the flexible anti-interference ability.
