Problems solved by technology

[0005] However, compared with the data transmitted by the existing direct communication, the V2X data is urgent and important. If the V2X data transmission is lost, it may cause serious problems, such as the loss of V2X data in the application scenario of automatic driving, which will lead to traffic accidents.
However, the resource allocation method of direct communication in the existing technology cannot well meet the business requirements of V2X, resulting in a decrease in data transmission efficiency.

Embodiment Construction

[0037] As mentioned in the background technology, compared with the data transmitted by the existing direct communication, V2X data is time-critical and important. If the loss of V2X data transmission may cause serious problems, such as the loss of V2X data in the application scenario of automatic driving, it will Can cause traffic accidents. However, the resource allocation method of direct communication in the prior art cannot well meet the service requirements of V2X, resulting in a decrease in data transmission efficiency.

[0038] The inventor of the present application has analyzed the prior art. In the direct communication in the prior art, once the base station configures a resource pool for automatic resource selection for the UE, the UE uses the transmission resources in the resource pool for data transmission. The UE does not need to detect whether the resource can be used, so there is no problem that the UE cannot obtain the transmission resource. However, in the ...

Abstract

A data transmission method and apparatus for V2X, a storage medium, and a user equipment. The data transmission method comprising: detecting transmission resources for V2X, and determining a resourcesubset; when the subset of resources is insufficient for transmission of V2X data, determinng to forward the V2X data through a base station. According to the technical scheme of the invention, the efficiency of resource allocation and data transmission in a V2X scene is improved.

Description

technical field [0001] This application is a divisional application of a patent application with an application date of August 12, 2016, an application number of 201610665571.6, and an invention titled "Resource configuration and data transmission method and device, base station, and terminal for V2X". [0002] The present invention relates to the communication field, and in particular to a data transmission method and device, storage medium, and user equipment for V2X. Background technique [0003] Currently, direct communication is introduced into a long term evolution (Long Term Evolution, LTE) system, and multiple user terminals (User Equipment, UE) can perform direct communication. In direct communication, there are two resource allocation methods, one is scheduled resource allocation (scheduled resource allocation), which is configured by the base station through dedicated signaling; the other is automatic resource selection (autonomous resource selection), the base st...
