Abstract

The invention discloses a wireless virtual mapping method in consideration of inter-cell interference under an ultra-dense environment. The method comprises modeling a ultra-dense network by using a random geometric Poisson point process, determining a channel and interference model through a network model, then virtualizing a wireless frequency resources, and dividing the frequency of a spectrum resource by using a wireless network mapping method so that the receiving signal-to-interference ratio of a user is guaranteed, interference is reduced, the throughput of the entire system is improved. On one hand, the spectrum allocation method in the present invention has a good theoretical performance guarantee; on the other hand, the wireless virtual mapping method is beneficial to implementation and has good application prospect.

Description
