Embodiment Construction
[0041] In the embodiment of the present invention, the first device performs signal detection in a non-persistent manner on the occupied time slot resource for sending signals. The non-persistent method means that the first device does not During the non-continuous signal detection process, if the signal sent by other devices is detected, other time slot resources for sending signals are reselected. In this way, the first device can still detect the resource collision of its own when no adjacent vehicle provides the first device with time slot collision information, and since the collision detection is performed in a discontinuous manner, relatively Compared with the continuous detection mode in which signal detection is performed in each signal transmission cycle, time slot resources can be saved and resource waste can be reduced.
[0042] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Disclosed are a resource detection method and apparatus, which are used for solving the problem that a vehicle for which there is no adjacent vehicle providing collision information fails to timely detect its own resource collision conditions. The resource detection method provided in the embodiments of the present invention comprises: a first device performing signal detection in a non-continuous mode on an occupied time slot resource for sending a signal, wherein the non-continuous mode refers to that the first device does not perform the signal detection in each signal sending cycle; and when the first device detects a signal sent by another device, reselecting another time slot resource for sending the signal. By means of the embodiments of the present invention, in the case where there is no adjacent vehicle providing collision information for a first device, the first device can still detect its own resource collision conditions. Moreover, since a non-continuous mode is used for collision detection, time slot resources can be saved, and resource waste conditions can be reduced.
Description
technical field [0001] The present invention relates to the field of communication technologies, in particular to a resource detection method and device. Background technique [0002] The Internet of Vehicles refers to the use of sensors on vehicles and roads to collect information on vehicles, roads and the environment, and to realize information sharing through mutual communication between vehicles, vehicles and people, and vehicles and roadside equipment, and to share information on the information network platform. Carry out extraction, sharing and effective utilization, effectively supervise vehicles and provide comprehensive services according to different functional requirements. [0003] In the IoV resource allocation mechanism based on Time Division Multiple Access (TDMA), the time slot is used as the unit for resource allocation. The basic idea is: when a node joins the network, it listens to the idle time slot in the frame The resource obtains a Basic Channel (BC...
