Claim of US Patent No. 10,602,524

1. A resource scheduling method for a vehicle infrastructure cooperative communication system, applied to a scheduling platform in the vehicle infrastructure cooperative communication system, comprising:receiving node position information from nodes of the vehicle infrastructure cooperative communication system;
calculating a distance between any two nodes among the nodes of the vehicle infrastructure cooperative communication system in accordance with the node position information, and determining a movement trend between the any two 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 any two nodes in accordance with the distance between the any two nodes and the movement trend, so as to acquire a determination result;
in the case that the movement trend indicates that the distance increases and a current distance between the first node and the second node is greater than a predetermined spatial multiplexing distance threshold, determining that the spatial-multiplexed time-frequency resources are capable of being used for the first node and the second node, otherwise determining that the spatial-multiplexed time-frequency resources are incapable of being used for the first node and the second node; and
in the case that the movement trend indicates that the distance decreases and the current distance between the first node and the second node is greater than a first sum, determining that the spatial-multiplexed time-frequency resources are capable of being used for the first node and the second node, otherwise determining that the spatial-multiplexed time-frequency resources are incapable of being used for the first node and the second node, the first sum being a sum of the spatial multiplexing distance threshold and a predetermined buffer distance; and
allocating available time-frequency resources for the nodes of the vehicle infrastructure cooperative communication system in accordance with the determination result.
