A resource allocation method and related equipment

Abstract

Provided are a resource allocation method and a related equipment. The resource allocation method comprises: upon creation of a first CAM data packet by a vehicle user terminal equipment (V-UE), if a target resource capable of transmitting the first CAM data packet has been allocated by a base station, transmitting, by the V-UE, the first CAM data packet directly on the target resource so as to effectively guarantee a data volume for communication between the base station and the V-UE; and if the target resource is not allocated by the base station, creating, by the V-UE, a BSR-V to enable the base station to allocate the target resource according to a creation interval of the first CAM data packet, thereby allowing the base station to allocate the target resource according to the creation interval of the first CAM data packet even when a resource previously allocated by the base station is not applicable due to changes in a driving state of a vehicle and a size of the CAM data packet.

Description

technical field [0001] The present invention relates to the field of V2V communication, in particular to a resource configuration method and related equipment. Background technique [0002] In the prior art, in order to improve traffic safety, concepts such as Intelligent Transportation System (Intelligent Transportation System, ITS) and Internet of Vehicles and related researches have become global hotspots. V2V (Vehicle to Vehicle, Vehicle to Vehicle) communication is an important content in the research of ITS and Internet of Vehicles. It can provide and support applications and business transmission related to road traffic safety, and is widely considered to be the key to improving vehicle driving safety. , Key technology to reduce traffic accidents. V2V communication can exchange information through wireless communication between vehicles, so that vehicles can obtain road condition information in a timely manner or receive information related to vehicle driving safety ...

AI Technical Summary

Problems solved by technology

As a distributed resource allocation method, although this resource allocation technology based on user free competition has the advantage of simple implementation, due to its lack of effective coordination among multiple users, different users may seize the same channel at the same time Resources send their own data, causing the data sent by multiple users to collide with each other, resulting in communication interference between multiple users, seriously affecting communication performance, and causing users' data to be unable to send and receive normally

Especially for services such as CAM that carry vehicle safety messages, this resource allocation method based on free competition will to a large extent lead to the failure of effective safety information interaction between vehicles, thereby increasing the probability of vehicle dangerous situations
