Abstract
An adaptive extended keeping reservation threshold probability mechanism system with resource watching window and dynamic back-off for contention-based 5G/B5G sidelink and a method thereof are disclosed. An adaptive extended Sigmoid mechanism can be applied to reduce a contention collision probability for the different types of flows contending a usage resource; a watching window can be applied to guarantee certain probability and reserve resource for a high priority flow; using dynamic truncated binary exponential (TBE) back-off mechanism can stagger the flows occurring resource collision to avoid the same consecutive collision, so as to effectively reduce contention collision probability, and improve resource usage rate and the probability of successful flow transmission. Therefore, the effect of minimizing collision probability and access delay and maximizing successful probability and throughput can be achieved.
