A Novel Method to Manage Inter-Cell Interference for Ultra-Dense Heterogeneous Networks in 5

The Ultra-dense Heterogeneous Network (HetNet), which consists of macro-cells and pico-cells, has been recognized as a key way of doing things to improve network performance. However, the increasing number of pico-cells also causes extreme interference including inter-cell interference and intra-cell interference. Therefore, interference management has become an important issue in ultra-dense HetNets, and the usual improved inter-cell interference coordination (eICIC) big plan/layout/dishonest plan is no longer fit for the high density of small cells. In this paper, a combination of two things/gas-electric vehicle interference management method based on energetic/changing eICIC and coordinated multi-point transmission (CoMP) is proposed. Firstly, a virtual cell is established based on the (features/ qualities/ traits) of ultra dense HetNets. Then, a novel joint energetic/changing eICIC big plan/layout/dishonest plan combined with multiuser beamforming is (sent out and used) to eliminate the inter-cell interference, and improve the throughput of virtual cell significantly without sharp decrease of throughput of macro-cell. What's more, a virtual cell based joint transmission big plan/layout/dishonest plan is (sent out and used) with a power control set of computer instructions, which can obviously increase the spectrum (wasting very little while working or producing something) of virtual cell edge. Test run (that appears or feels close to the real thing) results (check for truth/prove true) that the proposed big plan/layout/dishonest plan can (accomplish or gain with effort) better spectrum (wasting very little while working or producing something) both at macro-cell and virtual cell edges, and the network throughput is also improved. INTRODUCTION With the rapid development and innovations of mobile networking technologies, an entirely new era of mobile communications, i.e., the fifth generation (5G) of mobile communication systems, is coming. There is a consensus that 5G systems can be rolled out around 2020. 5G systems are expected to provide the society with full connection, which can break through the limitations of time and space to create all-dimensional, user-centered or service-centric interconnections between people and things [1]. 5G networks aim to meet various user quality-of-service (QoS) requirements in different application scenarios, e.g., in terms of data transmission rate and latency [2]. In scenarios where seamless wide-area coverage is needed, 5G systems should provide users with seamless highdata-rate services anytime and anywhere, even at cell edges or with high-speed (up to 500 km/h) mobility. In metropolitan areas where the density and volume of wireless traffic demand are both very high, 5G networks should provide dense hot-spot coverage with high capacity. In scenarios where reliable connections of a large number of widespread low-power nodes, e.g., wireless sensors, are needed, 5G networks should be able to connect millions of devices under the constraints of low power consumption and low cost per device. Extremely low latency and high reliability of 5G networks are required to meet the performance requirements of real-time, reliable and secure Cite this article as: A.V.
