Introduction to Recent Advances in 3D-MIMO Techniques and Standardizations
並列摘要
3-Dimensional Multiple-Input Multiple-Output (3D-MIMO) is an advanced multi-antenna technology that has recently been extensively considered for adoption in 5G cellular communications standard. As compared to the conventional downlink MIMO transmission, the base stations equipped with two-dimensional rectangular antenna array is capable of steering the signal in both horizontal and vertical domain, making the beam direction more precise. This not only increases the received signal strength effectively at the targeted receiver, but also reduces the interference to the other receiving nodes in vicinity. This article aims to introduce the basic concept and recent developments of 3D-MIMO, as well as the challenges of adopting this new technology in 3GPP standard.
