Abstract: D2D ( Device-to-device) improves communication quality by reusing cellular users’ spectrumresources, becoming one of the key technology for super-large data processing and massive devices ac-cessing in 5G. Due to load imbalance and co-frequency interference caused by distance change or in-crease in the number of users, this paper introduces an interference management strategy in 5C whereD2D communication and cellular communication coexist. By establishing a up and down link resourcemodel of D2D user reuse cellular communication to measure user throughput, we try to control transmit-ting power and the distance between user and base station to reduce the influence of interference on thesystem. Simulation results show that compared with other traditional algorithms, the network performanceof D2D communication based on interference management is significantly improved.

Key words: D2D communication: resource reuse: 5C: interference management, throughput
