Analysis of reconfigurable intelligent surface assisted networking

Abstract

Network assisted with reconfigurable intelligent surface is a kind of low-cost and low-power solution which can provide stable, continuous and ubiquitous connection to satisfy deep coverage requirements in 5G-Advanced (5G-A) and 6G era. A kind of reconfigurable intelligent surface assisted high and low frequency collaborative network architecture based on the positioning analysis of reconfigurable intelligent surface technology was proposed. The proportion of base station and reconfigurable intelligent surface collaborative deployment was analyzed. Furthermore, a interference reduction based on bandwidth design scheme was proposed to reduce adjacent frequency interference. System level performance simulation of network assisted with reconfigurable intelligent surface was verified to analyze the impact of reconfigurable intelligent surface deployment location and number of array elements under different UE distribution conditions. The simulation results show that the RIS-assisted network can significantly improve the edge and weak coverage area, so as to improve the network performance of the whole communication system.
