Embodiment

[0047] A relay deployment method that supports two-phase transmission of vehicle data, with figure 1 The scenario under a single macro base station is shown as an example, including the following steps:

[0048] 1) Generate the network facility deployment diagram of the existing urban road network: the process of generating the network facility deployment diagram of the existing urban road network is:

[0049] (1-1) Obtain urban road network information, geographical location and function information of deployed RSUs, small base stations and macro base stations from the city management department;

[0050] (1-2) According to the coverage area of ​​the macro base station obtained in step (1-1), the road network map of the corresponding area is generated, such as figure 2 shown;

[0051] (1-3) on the road network map that step (1-2) obtains, mark the geographic location and the communication capability of deployed RSU, small base station and macro base station, constitute the...

Abstract

The invention discloses a relay deployment method supporting two-stage transmission of vehicle data, which is characterized in that it includes the following steps: 1) generating a network facility deployment diagram of an existing urban road network; 2) based on a multi-layer ring cooperation mechanism Layer 3 cooperative trunk planning and deployment. This method can reduce the complexity of cooperative relay selection, reduce the total system power consumption and base station power consumption during C-V2X local communication, and improve the reliability of cooperative communication.

Description

technical field [0001] The invention belongs to the technical field of communications, and in particular relates to a relay deployment method for supporting two-stage transmission of vehicle-mounted data in an urban environment. Background technique [0002] Although the V2X (Vehicle-to-Everything, referred to as V2X) technology based on DSRC technology has been produced for a long time, due to the limitations of this technology, the advancement of this technology has stagnated. In the R14 standard version released by 3GPP in 2016, the C-V2X technology based on 3G / 4G / 5G cellular network (Cellular, referred to as C) communication is defined. Due to the scale advantages of terminals and infrastructure in the cellular communication industry, this technology has been obtained support from the automotive industry. Because the integrability of C-V2X reduces the production cost of automobile developers, and the deployment of cellular network infrastructure and road infrastructure ...
