Abstract: With the continuous development of 5G technology and the continuous growth of user needs, traditional computing methods can no longer meet the needs of the times. Ultra-Dense Heterogeneous Networks(UDHNs) can meet the requirements of 5G networks for high data rates and large system capacity, improve network coverage and flexibility, and reduce network deployment and maintenance costs. Therefore, UDHNs have become a key technology in 5G, but their application development has also brought thorny interference problems. In this paper, the interference problem in Ultra-Dense Heterogeneous Networksis discussed, the downlink interference scenarios are analyzed, and an optimization method based on interference randomization and inter-cell interference coordination is proposed, effectively improving the network performance. 

Keywords: UDHNs, Cell interference, Interference optimization
