报告摘要：Radio access network (RAN) slicing can construct multiple logically-isolated slices on a common roadside network infrastructure, enabling diverse Internet of vehicles (IoV) services with different quality of service (QoS) requirements. In this talk, we present a dynamic RAN slicing framework, in which radio spectrum and computing resource allocation, and computation workload allocation decisions are dynamically made for different IoV services. To obtain an optimal RAN slicing policy for accommodating spatial-temporal dynamics of vehicle traffic density, we first formulate a constrained RAN slicing problem with the objective to minimize long-term system cost. This problem cannot be directly solved by traditional reinforcement learning (RL) algorithms due to complicated coupled constraints among decisions. Therefore, we decouple the problem into a resource allocation subproblem and a workload allocation subproblem, and propose a two-layer constrained RL algorithm to solve them. Specifically, an outer layer first updates the resource allocation policy via an RL algorithm, and then an inner layer updates the workload allocation policy via an optimization subroutine. Extensive trace-driven simulations show that the proposed scheme effectively reduces the system cost while satisfying QoS constraints with a high probability, as compared with benchmarks.
