“…In [103], the cell was partitioned into smaller sectors according to the traffic load and an optimal 3D beam pattern design for each sector utilizing a 2D AAS, with downtilt weights applied to the elements in each port, was achieved using convex optimization. A recent work [53] made use of an FD-MIMO transceiver architecture proposed in the 3GPP TR36.897 and a simplified 3D channel model inspired from TR36.873 to propose algorithms for weight vector optimization in a single cell multi-user MISO setup, that were shown to outperform existing elevation beamforming methods.…”

Full dimension (FD) multiple-input multiple-output (MIMO) technology has attracted substantial research attention from both wireless industry and academia in the last few years as a promising technique for next-generation wireless communication networks. FD-MIMO scenarios utilize a planar two-dimensional (2D) active antenna system (AAS) that not only allows a large number of antenna elements to be placed within feasible base station (BS) form factors, but also provides the ability of adaptive electronic beam control over both the elevation and the traditional azimuth dimensions. This paper presents a tutorial on elevation beamforming analysis for cellular networks utilizing FD Massive MIMO antenna arrays. In contrast to existing works that focus on the standardization of FD-MIMO in the 3rd Generation Partnership Project (3GPP), this tutorial is distinguished by its depth with respect to the theoretical aspects of antenna array and 3D channel modeling. In an attempt to bridge the gap between industry and academia, this preliminary tutorial introduces the relevant array and transceiver architecture designs proposed in the 3GPP Release 13 that enable elevation beamforming. Then it presents and compares two different 3D channel modeling approaches that can be utilized for the performance analysis of elevation beamforming techniques. The spatial correlation in FD-MIMO arrays is characterized and compared based on both channel modeling approaches and some insights into the impact of different channel and array parameters on the correlation are drawn. All these aspects are put together to provide a mathematical framework for the design of elevation beamforming schemes in single-cell and multi-cell scenarios. Simulation examples associated with comparisons and discussions are also presented. To this end, this paper highlights the state-of-the-art research and points out future research directions.

“…Cell splitting (Andrews et al, ; Bhushan et al, ), realized using directional radiation patterns of sector antennas, which makes the frequency reuse possible and further enhances spectrum efficiency, appears to be the most appealing. Based on the scenario of splitting large cells into smaller cells, cell sectorization (Athley et al, ; Lee et al, ), which adopts broader frequency bandwidth, dual‐polarization channels (Cui et al, ; Luo et al, ), spatial diversity‐based multi‐input‐multioutput (Larsson et al, ; Ngo et al, ), and multibeam coverage technologies (Ericson et al, ; Swales et al, ), has been developed to fulfill communication requirements. The development trend tends to realize these functionalities on a single set of antennas for base transceiver system miniaturization owing to the increasing difficulty of identifying proper locations and the space to install them.…”

This paper examines the radiation characteristics of a shaped reflector antenna applied as an outdoor base station antenna for mobile communications. A simpler architecture in a reflector antenna can reduce the implementation cost and complexity of a base station antenna. The aim of this reflector antenna design is to resemble the required radiation characteristics of conventional base station antennas, which employ a single‐column phased array of antennas to radiate directional beam patterns for radio coverage in cell planning, while improving the existing drawback of overly large beam overlapping in adjacent sectors. It also discards the beam forming circuits of conventional base station antennas to reduce the level of passive intermodulation. This reflector antenna is fed by the elemental antenna of conventional base station antennas and is thus equipped with the functionalities of beam tilting and dual‐polarization radiation to fulfill the requirements of adaptive sectorized cell adjustment. Both numerical simulation and measurement results are presented to demonstrate the feasibility.

“…Two main research directions related to the vision as well as the topic of this paper can be summarized as follows. The first is to use a new frequency (A6: Above 6GHz), not the existing cellular frequency (B6: Below 6GHz) as broadband [4], and the second is to separate the service area into small areas in a horizontal/vertical direction and cover each area by one or more beams [3]. In this regard, this paper seeks to design and evaluate the mmWave-based multi-spot beam cellular system (hereafter, MWMSB cellular system or MWMSB), into which these two research directions are fused, in terms of the system capacity, thereby reviewing its possibility as 5G mobile communication.…”
