Sidelink Resource Scheduling in Unlicensed V2X Networks

The patent applies preliminary action by predicting future occupancy of sidelink resources based on historical occupancy information and average movement speed. The network infrastructure-side network unit determines a validity period for cell-related occupancy information and predicts which resources will be occupied by non-sidelink communication before scheduling sidelink resources. This allows the system to proactively avoid allocating resources that will soon be occupied, thereby reducing collision probability while maintaining high spectrum utilization.

The patent applies self-service by enabling the network infrastructure-side network unit to automatically predict occupancy patterns and make scheduling decisions based on historical data and movement speed calculations. The system uses pre-determined validity periods for occupancy information and automatically updates predictions as vehicles move through the cell. This automated approach reduces the need for complex manual configuration and intervention, thereby managing infrastructure complexity while maintaining effective collision avoidance through centralized scheduling.

The patent applies dynamics by making the validity period of occupancy information adaptive rather than fixed. The network infrastructure-side network unit determines the validity period as a function of the cell size and average movement speed of roadside network units. When vehicles move faster or the cell is larger, the validity period is shortened to maintain prediction accuracy. When movement is slower or the cell is smaller, the validity period can be extended to improve scheduling efficiency. This dynamic adjustment optimizes the balance between scheduling efficiency and prediction accuracy based on actual traffic conditions.
