Embodiment Construction

[0079] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0080] At present, in LTE-based V2V (vehicle-vehicle) technology, it is determined to adopt a method based on LTE D2D (Device to Device, LTE Direct) for improvement, in which control information (SA) and data information (Data) are transmitted through different channels , The receiving end first detects the SA information carried in the control information, so as to receive the data information according to the received control information.

[0081] In LTE-based V2V technology, there are two modes of resource selection:

[0082] One is the way that the UE spontaneously selects resources. The other is a base station-assisted resource selection method. When the vehicle is within the network coverage, the base statio...

Abstract

The present invention provides a resource reservation method and device, and belongs to the field of car networking technology. The objective of the invention is to solve the problems of false alarm and misjudgment of reservation resource occupation between vehicles and to improve efficiency of resource distribution. The method comprises the steps that: receiving dispatching distribution information sent by a first user device, wherein the dispatching distribution information comprises information of a time-frequency resource requiring reservation by the first user device; determining the number of times of reservation of the time-frequency resource by the first user device according to the dispatching distribution information; if receiving new dispatching distribution information sent bythe first user device about the time-frequency resource prior to failure of the number of times of reservation, renewedly determining reservation information of the time-frequency resource according to the new dispatching distribution information; or else, taking the time-frequency resource as an idle resource. The resource reservation method and device are mainly used in the car networking technology.

Description

Technical field [0001] The present invention relates to the technical field of Internet of Vehicles, in particular to a resource reservation method and device. Background technique [0002] In the LTE (Long Term Evolution) system, the method of direct communication between vehicles usually adopts a semi-continuous resource occupation method. The sending UE (User Equipment) obtains the resource occupation indication for data transmission according to the previously monitored scheduling assignment information (Scheduling assignment, SA), and determines the subsequent resource occupation state according to the principle of semi-continuous resource occupation, so as to select the resource. In this manner, it is usually necessary to carry related parameters such as the duration and period of subsequent resource occupation in the SA. [0003] However, in car networking communication, on the one hand, because the vehicle is in constant motion, the topology changes relatively quickly, and...
