The deployment of 5G urban networks is often described as a disruptive phenomenon since it enables new emerging Internet of Things (IoT) applications such as connected vehicles. Such applications demand new spectrum regulations to decrease network investment requirements by incentivizing operator cooperation. However, currently, no clear consensus exists on the appropriate regulatory regime for such an urban deployment. This work explores two main alternative regulatory scenarios for a connected vehicle use case. Both alternatives lower implementation costs while promoting competition. The first alternative is to maintain the current scheme of spectrum assignment while facilitating additional flexibility for infrastructure sharing (ex-post competition). The second alternative is to define local areas for monopoly 5G provisioning and define the conditions for competition ex-ante. Through agent-based simulations, this work shows that a local licensing of spectrum scenario may achieve better performance than alternative scenarios with traditional spectrum assignment. Additional sensitivity checks also help detail the practical trade-offs.

5G 城市网络的部署通常被描述为一种破坏性现象，因为它支持新兴的物联网 (IoT) 应用，例如联网车辆。此类应用需要新的频谱法规，通过激励运营商合作来降低网络投资需求。然而，目前对于此类城市部署的适当监管制度尚无明确共识。这项工作探讨了联网车辆用例的两种主要替代监管方案。这两种选择都降低了实施成本，同时促进了竞争。第一个选择是维持当前的频谱分配方案，同时促进基础设施共享的额外灵活性（事后竞争）。第二种选择是为垄断 5G 供应定义局部区域，并在事前定义竞争条件。通过基于代理的模拟，这项工作表明，频谱场景的本地许可可能比具有传统频谱分配的替代场景获得更好的性能。额外的敏感性检查也有助于详细说明实际的权衡。
