[0118] Such as figure 1 As shown, the first embodiment of the present invention provides a processing method for sending time intervals of synchronization information, which is applied to the node side, and the processing method includes:

[0119] Step 11, determining the first time interval at which the first node currently sends synchronization information;

[0120] Step 12, when there is a second node whose synchronization priority is lower than that of the first node among the surrounding nodes of the first node, and the second node exists continuously within the first preset time period, decrement small for the first time interval.

[0121] The situation corresponding to this step shows that there are nodes with a lower synchronization priority than the first node in the surrounding nodes, and the first node may be used as the synchronization source reference node of the second node with a lower priority. At this time, the first node needs to Increase the sending freque...

Abstract

The invention provides a method and device for processing transmission time intervals of synchronization information. The node-side processing method comprises the steps of determining a first time interval of a first node for transmitting synchronization information at present; when there is a second node with the synchronization priority being lower than the synchronization priority of the first node in nodes around the first node and the second node continuously exists within a first preset time period, reducing the first time interval, thereby reducing the transmission frequency, improving the resource utilization rate of the system and reducing synchronization signal interference; and when the synchronization priorities of nodes around the first node are all greater than or equal to the synchronization priority of the first node and the nodes around the first node continuously exist within a second preset time period, increasing the first time interval, thereby improving the transmission frequency, providing synchronization information with higher precision for low-priority nodes, improving the synchronization precision of the system, accelerating the synchronization convergence and improving the reliability of communication.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for processing the sending time interval of synchronization information. Background technique [0002] The vehicle-road collaborative communication system is based on wireless communication and other technologies for vehicle-vehicle and vehicle-road information interaction and sharing, and realizes intelligent coordination and cooperation between vehicles and infrastructure, so as to optimize the use of system resources, improve road traffic safety, and alleviate traffic congestion. First. [0003] Currently in the 3GPP standard research, the LTE (Long Term Evolution) D2D (device-to-device) communication standard defines the following scenarios for sending synchronization information, as shown in Table 1: [0004] [0005] Table 1 Scenarios where terminals send synchronization information in LTE D2D [0006] It can be seen from Table 1 that...
