Problems solved by technology

In the coverage area of ​​the cell, when the train is in different positions, the base station uses beams of different widths to serve the train; and a beam boundary determination scheme based on the bisection algorithm is proposed; this method can reduce the fluctuation of data transmission and improve the efficiency of train communication Stability; however, in some locations, the data transfer rate still fluctuates widely

Embodiment Construction

[0074]Further detailed description of the technical solutions of the present invention will be described below with reference to the drawings:

[0075]Such asfigure 1 As shown, the positional fair millimeter wave high-speed vehicle is a communication stabilized beamforming method, including the following steps:

[0076]Step 1: Build an intersection redundancy overlay network architecture: overwritten the train track area with two separate cellular networks, the two networks as backups, together constitute a staggered redundant overlay network model;

[0077]Among them, the interleaving redundant coverage network architecture uses two independent honeycomb cell networks in network i and network II to override the train track area, and the signals in each network are independently transmitted, and there is no need to cooperate with each other; at the same location at the top of the train Installing two mobile relays, they are all connected to the information processing center on the train; the...

Abstract

The invention discloses a method for stabilizing the beamforming of millimeter-wave high-speed rail vehicle-to-ground communication based on location fairness, which includes the following steps: Step 1: constructing an interleaved redundant coverage network architecture; Step 2: establishing a transmission beam width optimization problem; Step 3: determining beam allocation Solution: According to the problem of transmitting beam width optimization, calculate the required transmitting beam width and the corresponding beam boundary point position of the vehicle-mounted mobile relay node at each point within the coverage of the base station; Step 4: Switch the best service beam: through the train The positioning system obtains the position information of the train at the current moment, and switches the best service beam for the on-board mobile relay node according to the transmitted beam width and beam boundary point position obtained in the beam allocation scheme and the position information of the train; Step 5: Calculate the train Fluctuation factor and outage probability of communication systems. The invention has the advantages of improving the stability of data transmission in the high-speed rail wireless communication system and ensuring a lower probability of communication interruption.
