Embodiment Construction

[0085] In the embodiment of the present invention, a first device located in the vehicle fleet receives a discovery request message sent by a second device located in the vehicle fleet; the first device determines the resource pool used by the second device and all resources according to the discovery request message. Whether the resource pool used by the first device is the same; if the resource pool used by the second device is partly or completely the same as the resource pool used by the first device, the first device performs a resource collision avoidance operation. Because in the embodiment of the present invention, communication devices on different vehicles in the vehicle fleet need to be discovered before communication between the first device and the second device in the vehicle fleet, and the second device sends a discovery request message to the first device. , The first device will determine whether the resource pool of the first device and the resource pool of the...

Abstract

Embodiments of the present invention relate to the technical field of wireless communication, and in particular to a method and device for avoiding resource collisions in fleets, which are used to solve the problem in the prior art that there is no method for avoiding resource collisions in fleets in eV2X application scenarios. In the embodiment of the present invention, the first device in the fleet receives the discovery request message sent by the second device in the fleet; the first device judges the resource pool used by the second device and the resource pool used by the first device according to the discovery request message Whether they are the same; if the resource pool used by the second device is partially or completely identical to the resource pool used by the first device, the first device performs a resource collision avoidance operation. Since the first device in the embodiment of the present invention judges that the resource pool of the first device is partially or completely identical to the resource pool of the second device, it performs a resource collision avoidance operation, thereby effectively avoiding the use of the same resource pool between the first device and the second device A resource collision occurred.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a method and equipment for avoiding resource collision in a fleet. Background technique [0002] eV2X (enhancement of Vehicle to Everything) communication is an evolution of V2X (Vehicle to Everything) communication. The application scenarios of eV2X include the scene of a fleet (platooning), and the fleet is composed of several vehicles. Fleet. The leading car is driving in front, and the following car automatically keeps a small distance to travel, forming a train-like driving mode. There is a small distance between cars (1 meter or 2 meters) to move forward together. This distance between cars is long. It is much smaller than the distance between cars normally maintained by a person driving a motor vehicle, so that the motor vehicle can reduce wind resistance, reduce fuel consumption, and save driving manpower, which plays a role in increasing driving safet...
