Cooperative Resource Sharing Strategy With eMBB Cellular and C-V2X Slices

The emerging fifth generation (5G) wireless technologies support services with huge heterogeneous requirements. Network slicing technology can compose multiple logical networks and allocate wireless resources according to the needs of each user, which can reduce the cost of hardware and network resources. Nevertheless, considering how systems containing different types of users reduce the cost of resources remains challenging. In this paper, we study the system cost of two types of user groups requesting resource blocks (RBs) at the radio access network (RAN), which are the enhanced mobile broadband (eMBB) cellular user group and the cellular vehicle to everything (C-V2X) user group. In order to improve the rational utilization, we make dynamic resource pricing according to the needs of users. Then, we propose a Cooperative Resource Sharing (CRS) Algorithm, which makes two user groups jointly purchase and share resources. The simulation results show that the strategy used in this algorithm can effectively reduce the unit price of RB and minimize the total cost of the system.
