Abstract: The invention provides a resource allocation method based on interference avoidance in a satellite-ground integrated network and relates to the technical field of information and communication. According to the method, the fairness is taken into consideration, and the energy is efficient. The method comprises the following steps of S1, obtaining satellite beam isolation degree of different bands corresponding to CGC (Complementary Ground Component) base stations or users according to positions of the CGC base stations or the users in cells and arranging satellite beams of different bands according to the isolation degree; and S2, preferentially allocating the satellite beams with high isolation degree when resource allocation is carried out on edge users of the cells. According to the method, for a scene in which satellites are interfered by ground network terminal uplinks, through classification and arrangement of the isolation degree and through adoption of the resource allocation method of preferentially allocating the resources with relatively high isolation degree frequencies to the users, the same frequency interference is reduced fundamentally. The satellite-ground integrated network is guaranteed to be relatively high in throughput, energy efficiency and anti-interference performance, and the fairness among cell clusters is ensured.
