Embodiment Construction
[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0038] First introduce two basic concepts about 5G:
[0039] 1. 5G base station positioning technology: Based on the 5G communication network, the base station sends a signal, and the receiving terminal obtains the location of the terminal itself in the 5G cellular network by obtaining information in the signal header and information from differen...

The invention provides a 5G positioning networking design method and a system for rail transit. The method comprises the steps that 5G base station networking point locations in a preset rail space are acquired; based on the 5G base station networking point locations, a communication signal coverage rate and a positioning signal average coverage number are respectively obtained; and if it is judged that the communication signal coverage rate and the average positioning signal coverage number meet preset conditions, a target networking scheme is output. According to the embodiment of the invention, the coverage rate of the rail transit communication signals and the average coverage number of the positioning signals are considered; and whether to output the target networking scheme or not isdetermined by further judging the communication networking requirement and the positioning networking requirement, so that the communication networking requirement and the positioning networking requirement are comprehensively considered, and the defects that the positioning performance of the networking scheme is difficult to guarantee, the communication quality is easily influenced and the likein the prior art are avoided.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for designing a 5G positioning network for rail transit. Background technique [0002] With the development of 5G communication, its application fields are becoming more and more extensive. Among them, there are more and more applications using 5G signals for positioning. [0003] In 5G positioning technology, additional spectrum resources are needed to carry positioning information, but in general application scenarios, such as the lack of spectrum resources in orbital space, which affects signal transmission, and the coverage of positioning information is limited to the signal coverage of communication information; Due to the different forms of positioning signals in the same-frequency co-carrier positioning technology based on 5G, the coverage distance of positioning signals is larger than that of communication signals, but its positioning accuracy i...
