Embodiment 1

[0111] image 3 It is a flow chart of a V2V communication method provided by an embodiment of the present invention, and the method can be performed by figure 1 In the shown system architecture, the base station and the first vehicle terminal perform interactively, and the first vehicle terminal can be figure 1 Any vehicle terminal under the system architecture shown, such as image 3 As shown, the method may include the following steps:

[0112] S101: The base station sends a first SPS configuration parameter to a first vehicle terminal; the first SPS configuration parameter includes: a first SPS period.

[0113] Wherein, the first SPS cycle can be set according to the time law of the first vehicle terminal sending messages to other vehicle terminals, that is, it can be set according to the V2V business model contract sending rule; the first SPS cycle can include at least one scheduling control (Scheduling Control , SC) period, usually, the semi-persist scheduling period s...

Embodiment 2

[0184] Figure 6 A structural diagram of a vehicle terminal 30 provided for an embodiment of the present invention, used to execute the actions performed by the first vehicle terminal in Embodiment 1, such as Figure 6 As shown, the vehicle terminal 30 may include:

[0185] The receiving unit 301 is configured to receive a first semi-persistent scheduling SPS configuration parameter sent by a base station; the first SPS configuration parameter includes: a first SPS period.

[0186] Wherein, the first SPS cycle can be set according to the time law of the vehicle terminal sending messages to other vehicle terminals, that is, it can be set according to the V2V business model contract sending rule; the first SPS cycle can include at least one scheduling control (Scheduling Control, SC ) period, in general, the semi-persistent scheduling period semiPersistSchedInterval_Vue=min((V2V service period / SC period)*SC period, N*SC period).

[0187] The receiving unit 301 is further confi...

Abstract

The present invention provides a V2V communication method, a device and a system, which relate to the field of communication technologies and solve the problem that the scheduling cost of PDCCH information in the existing V2V communication is large. The method includes that after receiving a first SPS configuration parameter that is sent by a base station and includes a first SPS period, a first vehicle terminal receives first scheduling control information that is sent by the base station and used for instructing the first vehicle terminal to perform SPS activation, and sends a V2V data packet to a second vehicle terminal according to the first SPS period.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a vehicle-to-vehicle (Vehicle to Vehicle, V2V) communication method, device and system. Background technique [0002] With the continuous development of society, the popularity of automobiles is getting higher and higher. While driving travel brings convenience to people, it also brings certain negative effects to human society, such as: the rapid increase in the number of vehicles has caused traffic congestion and traffic accidents. Frequent and other issues. In order to avoid these problems, vehicles can obtain road condition information or receive information services in a timely manner through V2V communication. For example, vehicles can broadcast V2V information such as their own speed, driving direction, specific location, and whether they have stepped on the emergency brake to the surroundings. Vehicles, so that the drivers of surrounding vehicles can...
