Abstract

The invention provides a method for scheduling resources based on beam hopping. The method comprises the following steps that: a satellite coverage area is divided into a plurality of cells; each cellis divided into a plurality of rectangular units with equal sizes; a first three-dimensional matrix is used for representing actual channel capacities of each rectangular unit at different times; a second three-dimensional matrix is used for determining whether to serve each rectangular unit at different times, wherein an element 1 of the second three-dimensional matrix indicates that the corresponding rectangular unit is served by beam hopping at a certain time and an element 0 indicates that the corresponding rectangular unit is not served at a certain time; a product of the first three-dimensional matrix and the second three-dimensional matrix expresses a target matrix; the second three-dimensional matrix is adjusted to maximize the sum of all elements of the target matrix; and the corresponding matrix unit is served according to the adjusted second three-dimensional matrix. With the method provided by the invention, beam hopping resource allocation of all satellite coverage areasis optimized for the occasion of rapid movement of a low-earth orbit satellite, so that the precious spatial resources are scheduled well.

Description

technical field [0001] The present invention generally relates to the field of satellite communication, and in particular relates to a method for scheduling resources based on beam hopping. Background technique [0002] In recent years, with the development of low-earth orbit satellite (LEO, low-earth orbit satellite) mobile communication technology, the low-earth orbit satellite communication service has attracted widespread attention due to its own advantages. With the continuous expansion of the country's strategic needs, people are no longer satisfied with the existing communication technologies on the ground, but focus on realizing the integration of space and ground, global coverage, multimedia satellite communication systems for personal mobile communication networks, low-orbit broadband Satellite networking communication technology is an important means to realize communication globalization and commercialization. However, due to the low orbit altitude and changing ...
