Abstract:
Indoor deployment with low cost and high capacity has shown to be a cost-effective solution in 5G wireless networks. In indoor 5G networks, Radio Dot (RD) units handle the wireless interfacing between UE devices and the core network. Strategic placement of indoor 5G RD units to ensure higher coverage of the space with optimal performance is challenging, since various factors could affect signal penetration, including floor plan, building materials, wall construction, frequency band, interference, dynamic factors like user density, etc. Most static parameters are well considered during the deployment stage, with deployment tools and network planning strategy. However, the dynamic impact of user density and distribution on channel quality and performance is still an open research area. With the user equipment (UE) positioning and channel quality indicator (CQI), the areas with poor channel quality data could be detected and further analyzed to dynamically determine RD locations and adjust accordingly for better network performance, without extra radio hardware costs introduced. This paper adopted the K-means clustering algorithm to evaluate the scenario where all the RD unit locations can be adjusted. Further, a Node Adjustment algorithm for RD units was proposed to improve indoor 5G network performance for a cost-efficient solution. The number of UEs and their distribution were simulated, and a comparative evaluation was conducted for different algorithms and various scenarios. The experimental results showed that considering dynamic information to adjust RD unit placements in a building could provide a cost-efficient solution to optimize indoor 5G network performance.
