5G era has arrived with huge reforms. Rational allocation and utilization of 5G spectrum resources, improvement of signalto-noise ratio, and reduction of interference caused by the frequency allocation are the premise and guarantee of the popularization of 5G communication. Therefore, based on 5G cellular networks and starting from the background application of 5G, new algorithms such as water-filling algorithms and simultaneous iterative water-filling algorithms are given compared with previous algorithms such as integer frequency reuse and fractional frequency reuse, 5G frequency allocation model is elaborated, the selection of the corresponding model under the actual environmental interference like the propagation loss is analyzed, and methods and techniques are constantly put forward to implement corresponding frequency allocation. Ultimately, the relationship between the signal-to-noise ratio and average capacity is obtained, and specific measures concerning how to optimally improve the average capacity to exploit limited spectrum resources with higher efficiency by 5% and lower interference by 3%.
