Networking method and device for co-band base stations

Abstract

Embodiments of the present invention provide a method and device for networking base stations in a common frequency band, which relate to the field of communication technologies and can improve the positioning accuracy of a ground base station network. The solution of the embodiment of the present invention includes: according to the communication power of the communication base station to transmit the communication signal and the spreading gain of the spreading code, determine the positioning power of the positioning base station to transmit the positioning signal; then according to the positioning power and the first transmission loss value, determine the cellular network The maximum side length of each honeycomb hexagon in . And according to the positioning power and the second transmission loss value, determine the minimum value of the side length of each cellular hexagon in the cellular network; the positioning base station in each module in the cellular network multiplexes a set of spreading code groups, each module is different The base stations correspond to different spreading codes, and the spreading codes corresponding to the base stations at the corresponding positions of each module are the same; then, from the range between the minimum side length and the maximum side length, a value is selected as the hexagonal value of each cell in the cellular network. The side length of the shape.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for networking a common frequency band base station. Background technique [0002] The ground base station network has strong indoor and outdoor signal coverage due to its good reliability, anti-interference and networking flexibility. The ground base station network can be realized by time-division orthogonal frequency division multiplexing (TC-OFDM, TimeCodeDivision-Orthogonal Frequency Division Multiplexing) technology. The TC-OFDM system is a system that can realize the integration of communication and navigation, and can realize high-precision indoor and outdoor Seamless positioning. [0003] However, when determining the ground base station network in the related art, only the coverage of the base station, the number of base stations, and the influence of the location height of the base station on the positioning accuracy are considered...

Problems solved by technology

[0003] However, when determining the ground base station network in the related art, only the coverage of the base station, the number of base stations, and the influence of the location height of the base station on the positioning accuracy are considered, and the interference of the communication signal to the positioning signal in the case of a large-scale network is not considered. The problem of mutual interference between the positioning signals sent by the base station makes the positioning accuracy of the ground base station network constructed by the existing base station networking method low
