Embodiment Construction

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

[0080] At present, in the LTE-based V2V (vehicle-vehicle) technology, it is determined to adopt the LTE D2D (Device to Device, LTE Direct) method for improvement, in which the 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 resource selection modes:

[0082] One is a manner in which the UE selects resources spontaneously. The other is the resource selection method assisted by the base station. When the vehicle is wit...

Abstract

The present invention provides a resource reservation method and device in the technical field of Internet of Vehicles, which is used to solve the problem of false alarm and misjudgment of reserved resource occupation between vehicles, and improve the efficiency of resource allocation. The resource reservation method of the present invention includes: receiving scheduling allocation information sent by the first user equipment, including information on time-frequency resources to be reserved by the first user equipment in the scheduling allocation information; determining the scheduled allocation information according to the scheduling allocation information The number of times the first user equipment reserves the time-frequency resource; if the new scheduling allocation information about the time-frequency resource sent by the first user equipment is received before the number of reservations expires, then according to the The new scheduling allocation information re-determines the reservation information for the time-frequency resource; otherwise, the time-frequency resource is regarded as an idle resource. The invention is mainly used in the Internet of Vehicles 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 an LTE (Long Term Evolution, Long Term Evolution) system, the way of direct communication between vehicles usually adopts a semi-persistent resource occupation way. The sending UE (User Equipment, user equipment) obtains the data transmission occupation resource indication according to the previously monitored scheduling assignment information (Scheduling assignment, SA), and determines the subsequent resource occupation status according to the principle of semi-persistent resource occupation, so as to select resources. In this manner, it is usually necessary to carry relevant parameters such as the duration and period of subsequent resource occupation in the SA. [0003] However, in the IoV communication, on the one hand, because the vehicle is in constant motion and the topology cha...
