Embodiment Construction

[0022] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0023] The basic idea of ​​the present application is to perform priority indication between the PC5 port and the Uu port corresponding to each subframe, so as to perform data transmission when the PC5 port and the Uu port coexist as required.

[0024] figure 1 It is a schematic flow chart of the data transmission method in this application. figure 1 The applicable situation of the process is: the PC5 port and Uu port data are carried on the same carrier or the vehicle terminal does not support sending information on different carriers at the same time, such as figure 1 As shown, the method includes:

[0025] Step 101 , the vehicle terminal receives the RRC layer configuration period T and the priority indication information configured in the current configura...

Abstract

The invention discloses a data transmission method in a vehicle direct connection system. When PC5 port data and Uu port data are carried on the same carrier wave or a vehicle terminal does not support information transmission on different carrier waves at the same time, the method includes that the vehicle terminal receives an RRC layer configuration period T and priority indication information configured in a current configuration period, wherein the priority indication information includes priority indication of each sub frame in the current configuration period and is used for indicating the priority relation between a PC5 port and a Uu port; as for each sub frame having the PC5 port data and Uu port data at the same time, according to the priority indication corresponding to the sub frame in the priority indication information, the priority relation between the PC5 port and the Uu port on the sub frame is determined and transmission of the PC5 port data or the Uu port data is performed according to the determined priority relation.

Description

technical field [0001] The present application relates to communication technology, and in particular to a data transmission method in a vehicle through system. Background technique [0002] With the improvement of people's living standards, the number of car ownership has increased rapidly, and the increasing number of vehicles on roads such as urban areas and expressways has led to an increase in traffic accidents. Therefore, road traffic-related safety issues have become one of the basic issues affecting people's livelihood. The Internet of Vehicles technology organically combines people, vehicles, roads and networks through direct communication between vehicles, which can greatly reduce the probability of traffic accidents. [0003] In direct vehicle communication, the LTE protocol plans to use uplink resources for inter-vehicle communication, that is, information on the PC5 port of the vehicle is transmitted using uplink time-frequency resources. In this case, when the...
