On mm Wave Radio Network Planning based on a Centralized Access Control

Abstract

In the recent years, we are witnessing an increasing demand of higher throughput, lower latency, higher reliability, and more efficient energy consumption. In order to meet these requirements in the future 5G cellular network, we adopt Device-to-Device communications, 60 GHz unlicensed band transmissions and adaptive beamforming techniques. The symbiosis of these technologies provides multi-Gigabit data rates, improved system capacity, strong interference reduction, while reducing eNodeB data traffic, end-to-end latency and power consumption. On the other hand, a major issue is the limited communication range due to the high path loss. At the aim of extending these benefits to a wide indoor scenario, we consider a Millimeterwave Mobile Broadband (MMB) system, consisting of multiple mmWave Access Points (APs) interconnected among themselves through a wireless backhaul network at 60 GHz. In this scenario, APs need to be properly deployed to ensure the system functioning, i.e., a radio network planning is needed. Since planning a cellular system depends on a large number of aspects, we need to carry out a proper analysis which takes into account not only the specific characteristics of MMB systems, but also the adopted Access Control scheme. In this paper, on basis of our previously proposed Access Control scheme, we provide some hints for planning a MMB system, organized in two phases. First, we derive coverage planning constraints. Second, the capacity planning and parameter configuration are derived in a network topology fulfilling the coverage constraints.
