The embodiment of the invention provides an indoor mirror virtual relay arraignment method and device. The spatial coordinate information of a virtual reflecting surface preset to be corresponding toeach side wall, the spatial coordinate information of a transmitter and the spatial coordinate information of the preset receiver arranged in the indoor communication area are acquired; the communication area is divided into the communication subarea of each belonging virtual reflecting surface according to the spatial coordinate information of the virtual reflecting surface, the spatial coordinate information of the transmitter and the spatial coordinate information of the communication area; polygonal approximation is performed on each communication subarea so as to acquire the polygonal area in each communication subarea and acquire the spatial coordinate information of the polygonal area; and the arrangement area on the virtual reflecting surface is acquired according to the spatial coordinate information of the virtual reflecting surface, the spatial coordinate information of the transmitter and the spatial coordinate information of the polygonal area so as to determine the position and the size of the indoor virtual relay, accurate indoor arrangement can be facilitated and the communication interruption probability can be greatly reduced.
Description
technical field [0001] The present invention relates to the field of relay technology, in particular to a method and device for laying out an indoor mirror virtual relay. Background technique [0002] With the widespread application of the fourth-generation mobile communication system (4G), more and more researchers, operators, and equipment manufacturers are actively paying attention to and promoting the development of the fifth-generation mobile communication (5G). The purpose of 5G communication is to achieve a transmission rate of Gbps, and the basic requirement is to achieve low latency and high reliability. The main technologies involved in 5G include millimeter wave, massive MIMO, beamforming, etc. The effective use of large unlicensed frequency bands (such as 60GHz) in millimeter waves is the fundamental means to achieve high-speed transmission of 5G, and because the antenna size is proportional to the wavelength of electromagnetic waves, the short wavelength charac...
