RESOURCE SCHEDULING METHOD AND DEVICE FOR VEHICLE INFRASTRUCTURE COOPERATIVE COMMUNICATION SYSTEM, AND NODE OF VEHICLE INFRASTRUCTURE COOPERATIVE COMMUNICATION SYSTEM
First Claim
1. A resource scheduling method for a vehicle infrastructure cooperative communication system, comprising:
- receiving node position information from nodes of the vehicle infrastructure cooperative communication system;
calculating a distance between the nodes in accordance with the node position information, and determining a movement trend between the nodes, the movement trend indicating that the distance decreases, remains unchanged or increases;
in the case that the movement trend indicates that the distance decreases or increases, determining whether or not spatial-multiplexed time-frequency resources are capable of being used for the nodes in accordance with the distance between the nodes and the movement trend, so as to acquire a determination result; and
allocating available time-frequency resources for the nodes in accordance with the determination result.

Abstract
The present disclosure provides in some embodiments a resource scheduling method and a resource scheduling device for a vehicle infrastructure cooperative communication system, and a node of the vehicle infrastructure cooperative communication system. According to the present disclosure, a movement trend between nodes is determined in accordance with node position information, so as to spatially multiplex time-frequency resources and prevent the frequent adjustment of time-frequency resources, thereby to reduce signaling overhead for allocating the time-frequency resources and improve utilization of the time-frequency resources.
