Problems solved by technology

It can be seen that the transmission mechanism based on the Uu interface needs to distinguish whether to use the Uu interface unicast mechanism or the eMBMS or SC-PTM mechanism, and the scheme of how to select the transmission mechanism according to the distribution of receiving terminals and the structure of the cell has not been realized in the prior art

Embodiment 1

[0084] Embodiment 1: The base station realizes the scheme of selecting the propagation mechanism of vehicle communication data:

[0085] From the perspective of implementation, it is assumed that the base station equipment supporting V2V communication can obtain some topology-related information in advance. Specifically, the base station needs to be able to have certain self-coverage information (not required to be accurate to the meter level), topological relationship information of adjacent cells, and vehicle driving area information (such as in the figure 1 In the shown scenario, the vehicle travels along a predetermined route, and the base station needs to obtain the route information). Such information enables the base station to be more intelligent in choosing the propagation method.

[0086] The specific plan is as follows:

[0087] 1. When the terminal sends V2V data to the base station, the terminal needs to indicate to the base station whether the service associate...

Embodiment 2

[0095] Embodiment 2: The scheme of selecting the transmission mechanism of vehicle communication data by the network side equipment:

[0096] From the perspective of implementation, it is assumed that the network-side device supporting V2V communication can obtain some topology-related information in advance. The specific plan is as follows:

[0097] 1. When the terminal sends V2V data to the network-side device, the terminal needs to indicate to the network-side device whether the service associated with the data is a unicast service or a multicast service. It should be noted that the indication can be indicated in the user plane data, and the user plane data may need to arrive at the network side device first, and then the network side device sends it to the relevant base station according to the scope of the cell involved.

[0098] 2. After receiving the data sent by the terminal and identifying the type of unicast service or multicast service, the network side device dire...

Abstract

The invention provides a data transmission method and device for vehicle communication, a base station, and network side equipment. The method comprises the steps: receiving vehicle communication data transmitted by a transmitting terminal; judging which one of a unicast mode and a broadcast mode is used for transmitting vehicle communication data according to the number of receiving terminals for receiving vehicle communication data or prompt information transmitted by the transmitting terminal; directly transmitting the vehicle communication data to the receiving terminal in a unicast mode when the unicast mode is determined to be employed for transmitting the vehicle communication data; determining a needed broadcast range of the vehicle communication data when the broadcast mode is determined to be employed for transmitting the vehicle communication data, and carrying out the transmission of the vehicle communication data in a mode of single-cell broadcast or multi-cell broadcast according to the needed broadcast range of the vehicle communication data. According to the technical scheme of the invention, the method achieves the support for a V2V transmission mechanism based on a Uu interface, and can achieve high-efficiency V2V communication saving the transmission resources.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a data transmission method for vehicle communication, a data transmission device for vehicle communication, a base station and a network side device. Background technique [0002] V2X (Vehicle to X, vehicle to specific target communication) is a project approved by 3GPPRAN#68, which mainly studies the vehicle data transmission scheme based on the 3GPP communication protocol. V2X includes V2V (VehicletoVehicle, vehicle-to-vehicle communication), V2P (VehicletoIndividualPerson, vehicle-to-person communication), V2I (VehicletoInfrastructure, vehicle-to-road communication), etc. In principle, V2V communication can be carried out through the Uu interface (the interface between the user equipment and the base station) and the PC5 interface (the interface between the user equipment and the user equipment). 3GPP is currently studying and discussing two mechanisms. The exi...
