In this paper we are focusing on the ultimate limit of frequency allocation in a 5G network.
To study this problem, we proposed a matrix graph model and constructed an analytical framework combining matrix graph coloring (MGC) and maximum weighted independent set (MWIS),
based on properties of large-scale small-cell networks.
Utilizing this model, we obtain an approximation algorithm that achieves a bounded gap to the optimal performance with a complexity growing linearly with the network size, despite the NP-completeness of the MGC problem.
Therefore, if we could build a proper matrix graph, we can find the nearly-optimal way to allocate resources like frequencies and time slots. Moreover, the proposed scheduling algorithm has lower computational complexity if cells are smaller and inter-cell interference are more complicated. Thus, we conclude that frequency allocation in high-interference smallcell networks can be carried out efficiently and the small-cell networks are indeed practical for the future 5G network
Simulation results support our theories.
