Research on 5G-R Handover Algorithm with Improved Fuzzy Logic

A 5G-R handover algorithm with improved fuzzy logic is proposed to address the issues of fixed traditional algorithm parameters for high-speed railway in future 5G-R communication scenarios. Firstly, a wireless signal propagation model for 5G-R was established in open scenes such as suburban areas; Secondly, parameters such as railway speed, Received Signal Reference Power, and Signal to Interference plus Noise Ratio were selected, and fuzzy processing was performed on them using trapezoidal and triangular membership functions as input values for the fuzzy inference system; Once again, a hierarchical fuzzy reasoning system was designed, which reduces the number of fuzzy rules through hierarchical reasoning and outputs the adjusted hysteresis threshold value after deblurring; Finally, the simulation results show that compared with similar algorithms, the proposed algorithm has lower handover delay and effectively improves the stability of high-speed railway handover.
