Abstract

The invention discloses a wireless transmission method and a wireless transmission device based on 3D MIMO. The method comprises the steps of building a communication connection between a base station preconfigured with an active antenna array and user equipment, and building a 3D MIMO channel model; when a part of active antenna units in an active antenna array are failed, automatically re-configuring the active antenna array to achieve redundancy; generating a 3D pre-coding matrix via the 3D MIMO channel model, and forming beam forming vectors with high resolution in two dimensional directions, thus acquiring multi-user multiplexing gain. According to the method and the device provided by the invention, services and control provided by cellular network infrastructures such as base stations are used for achieving multi-user MIMO, multi-cell and multi-dimension cooperative transmission, so that network deployment flexibility is further improved, a coverage range is enlarged, network capacity and transmission efficiency are enhanced, robustness of the system is increased, and power consumption of the base station and a terminal are reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication equipment, in particular to a method and device for wireless transmission based on 3D MIMO. Background technique [0002] With the rapid development of the mobile Internet, business data traffic has increased sharply, which has brought great adjustment pressure to the existing wireless network. For the current mainstream communication systems (LTE, LTE-A), increasing system capacity and reducing interference are still is the most important development goal. With AAS (Active Antenna System) in 3GPP (Third Generation Partnership Project, the goal of 3GPP is to achieve a smooth transition from 2G network to 3G network, to ensure backward compatibility of future technologies, to support easy network construction and inter-system Roaming and compatibility), 3D MIMO, one of the focuses of new wireless technologies, has received more and more attention. MIMO (Multiple-Input Multiple-Output...
