V2V Resource Allocation for High-Priority User Equipment

The patent implements differentiated resource allocation where high-priority user equipment receives preferential treatment in resource allocation. The base station identifies high-priority user equipment and allocates V2V resources from the first resource pool specifically to these users, ensuring they obtain sufficient resources even when overall V2V resources are limited. This local quality differentiation resolves the contradiction by sacrificing overall fairness to ensure reliable service for critical users.

The patent dynamically adjusts resource allocation based on user equipment priority levels and real-time resource availability. When V2V resources are sufficient, normal allocation proceeds; when resources are insufficient, the system dynamically shifts allocation toward high-priority users by allocating from the first resource pool and preventing low-priority users from occupying resources needed by high-priority users. This dynamic adaptation resolves the contradiction between fairness and reliability.

The patent segments V2V resources into a first resource pool dedicated to high-priority user equipment and a second resource pool for other user equipment. By dividing the resource pool in this manner, the system ensures that high-priority users have guaranteed access to resources while low-priority users can utilize remaining resources, thus maintaining both high resource utilization and reliable service for critical users.

The patent reserves the first resource pool in advance for high-priority user equipment before allocating resources to low-priority users. This preliminary action ensures that when high-priority users need resources, they can immediately obtain them from the pre-reserved pool without competing with low-priority users, thereby maintaining both high resource utilization overall and reliable availability for high-priority users.
