System Coverage and Capacity Analysis on Millimeter-Wave Band for 5G Mobile Communication Systems with Massive Antenna Structure

Abstract

The use of a millimeter-wave band defined as a 30–300 GHz range is significant element for improving performance of 5th generation (5G) mobile communication systems. However, since the millimeter-wave signal has peculiar propagation characteristics especially toward non-line-of-sight regions, the system architecture and antenna structure for 5G mobile communications should be designed to overcome these propagation limitations. For realization of the 5G mobile communications, electronics and telecommunications research institute (ETRI) is developing central network applying various massive antenna structures with beamforming. In this paper, we have introduced the central network and evaluated the system coverage and capacity through C++ language-based simulations with real geospatial information.

An Enhanced Handover Scheme to Provide the Robust and Efficient Inter-Beam Mobility

“…In addition, the gain of the transmitting antenna according to the polar angle (θ) as depicted in Fig. 2 is defined as G(θ) ≈ G(0)−10·log(e)·(θ/ω) 2 [dBi] where ω is a constant [7]. Here, HP BW indicates the polar angle θ HBP W where G(0) − G(θ HP BW ) = 3dB.…”

“…This means that the network capacity can be additionally increased as the number of beams increases if the BS controls a single beam as a single cell. For this reason, in order to maximize the network capacity, it can be considered that multiple beams transmitted in fixed directions by a BS are continuously arranged in the mmWave mobile communication system [2]. This letter calls the system described in [2] as the continuously arranged beam (CAB) system.…”

Performance analysis with dynamic beam control using millimeter-wave band on 5G mobile communications

“…Since the very short wavelength of the millimeter-wave band enables the miniaturization of the antenna size, multiple antennas are easily integrated to a BS structure. As a result, the BS can form multiple beams simultaneously with multiple antennas, and it can help the SDMA to be easily implemented in the BS [5,11].…”
