Description
Technical field
The present invention relates to the collaboration diversity application process in the car networking communication technology, more particularly to a kind of 3GPP V2X.
Background technology
With increasing rapidly for car ownership and density, and the frequent generation of road traffic accident, car networking has been increasingly becoming one of focus direction of the communications field.Car networking passes through being in communication with each other between vehicle and means of transportation, the technologies such as combined positioning system, sensor, intelligent vehicle control system, machine vision analysis, the sensing range and perception degree of automobile active safety system can significantly be lifted, traffic accident odds is reduced, and can indirectly be realized alleviating traffic congestion, be lifted road capacity and other effects.
V2X is the communication technology that car networking field is exclusively used in 3GPP, including the different types of vehicle-carrying communication technology such as V2V (Vehicle to Vehicle), V2I (Vehicle to Infrastructure), V2P (Vehicle to Pedestrian).V2X communications rely primarily on terminal direct connection to be carried out, and specific communication mechanism not yet determines, basic ideas are, based on the technical indicator such as low delay, high reliability, the intensive networking of support in car networking, on the basis of the existing 3GPP D2D communication technologys enhancing to be improved.
In D2D technologies, node exist need broadcasted service message when, need send service message itself with to should service message the class message packet of control message two.Node needs to obtain and sends the running time-frequency resource that two class messages are used, for the UE in network coverage, can be its specified transmission resource to eNodeB propositions transmission request and by eNodeB, it is also possible to the transmission resource for using independently is selected in the resource area (referred to as scheduling resource pond/data resource pond) for being exclusively used in sending D2D control messages and D2D service messages of network configuration.It is determined that sending after resource location, node states the associated control message of the service message firstly the need of the control message of the broadcast service message in scheduling resource pond, including service message sends position etc.；Service message is sent on the resource location for subsequently indicating in control message.
For the broadcast service message message for needing to carry out multi-hop forwarding, relaying UE receiving service message message, and will judge that the message needs after forwarding, to repeat above broadcast transmission process.For multi-hop broadcasting service, the process that service message message is sent between its different node is separate.The multi-hop forwarding behavior for supporting various types of messages is not yet determined whether in V2X.D2D communication mechanisms are transplanted to behind V2X fields, the characteristic such as the node high density of V2X systems itself, periodical communication take place frequently, high translational speed causes the performance of the mechanism to meet V2X system requirements, needs to strengthen it.
