Embodiment 1

[0032] The embodiment of the present invention proposes a future-oriented mobile communication method for disseminating mixed scenes inside and outside the city and land and sea, and the steps are as follows:

[0033] 101: Read the topography of the scene;

[0034] 102: Determine the upper and lower boundary conditions;

[0035] 103: Use the three-dimensional parabolic equation algorithm to calculate the distribution of mixed scenes inside and outside the city and land and sea;

[0036] 104: According to the actual parameters of the modeling scene (number of sampling points, operating frequency, step interval, wave number, etc.), the path loss and field distribution characteristics of the scene are obtained through simulation;

[0037] 105: Properly deploy base station antennas.

Embodiment 2

[0039] The main steps in the present invention are briefly described below.

[0040] Step A: Modeling the mixed scenes inside and outside the city and land and sea;

[0041] Among them, the modeling objects include: terrain, landform, ocean and other elements.

[0042] Step B: Determine the upper and lower boundary conditions;

[0043] Wherein, the step B includes:

[0044] Step B1: The upper boundary is generally determined by the refractive index of the atmosphere. This study was carried out on the propagation characteristics of radio propagation, therefore, complex factors in the atmospheric environment must be taken into account. The main influence of atmospheric environment on radio wave propagation depends on the refractive index n. If the surface of the earth is assumed to be a plane, and the electric wave ray is equivalent to a curved ray, then a modified refractive index M about the atmosphere can be defined. In this case, confirm it as image 3 .

Abstract

The invention discloses a city inside and outside and land and sea mixed propagation method for future mobile communication. The method comprises the following steps: reading scene topography and landform; determining boundary conditions; according to a three-dimensional parabolic equation algorithm; simulating urban internal and external and mixed scene path loss and field distribution under a 5Gor 6G frequency band; reasonably deploying a base station; wherein the boundary condition determination is specifically as follows: determining an upper boundary condition of radio wave propagation determined by an atmospheric refractive index; determining a lower boundary condition determined by the surface; wherein the three-dimensional parabolic equation algorithm can specifically comprise thefollowing steps: determining a current source; determining an initial magnetic field according to the excitation source; determining a stepping magnetic field according to the initial magnetic field;employing window functions. In combination with a three-dimensional parabolic equation algorithm, the path loss and the field distribution situation in a city internal and external and land and sea mixed scene in a future 5G or 6G scene are obtained, so that reasonable base station deployment is carried out on the scene, and the communication quality is improved.

Description

technical field [0001] The invention relates to the field of radio wave propagation, in particular to a future-oriented mobile communication propagation method in and out of cities and in land and sea mixed scenarios. Background technique [0002] Radio wave propagation has become a hot topic in the field of mobile communication technology. Accurate prediction of radio wave propagation characteristics can effectively guide the allocation of mobile communication network resources and avoid waste of network resources, so that it can maximize its effectiveness. Therefore, in order to promote the development of radio wave propagation research, many domestic and foreign experts and scholars continue to explore new methods and new technologies for accurately predicting radio wave propagation characteristics in different frequency bands. Among them, for the developing fifth generation mobile communication (The 5 th Generation Mobile Communication, 6G) and the future sixth genera...
