Abstract
In order to support dramatically increased traffic from diverse network services, deployment of ultra dense networks to improve the overall capacity of the fifth generation (5G) wireless networks becomes inevitable. However, network densification with increased number of small cells brings significant challenges in terms of quality of service provisioning and deployment cost due to increased network complexity, signalling overhead and inter-cell interference. In this paper, virtual small cell (VSC), which is formed adaptively according to traffic condition and service requirements, is investigated as a solution for cost-effective and reliable service provisioning in 5G ultra dense networks. A K-means clustering based VSC formation scheme is proposed in this paper, and the corresponding protocol conversion for data transmission across unlicensed and licensed networks at cell head (CH) is developed. Based on the VSC architecture design, a new resource allocation algorithm is also proposed for VSC scenario in order to improve the system throughput with comparable fairness.
