Resumé: Although it is simple to isolate and slice compu2ng and network resources for the core network (CN) elements, the Radio Access Network (RAN) presents a significant challenge. Besides, it is essen2al to introduce flexibility and greater u2liza2on of network resources by providing only the necessary network resources to meet the ac2vated slices requirements and guarantee op2mal radio resource usage. Several works have addressed the challenges of enforcing network slicing at the RAN in the context of 4G, but a few discussed the case of 5G. Indeed, 5G New Radio (NR) introduces several new mechanisms to improve the physical efficiency to meet the requirement of high data rate and low-latency communica2on, such as bandwidth part and physical numerology, which can be combined to further separate the network slices at the RAN. This thesis aims to study and propose new mechanisms and solu2ons to enforce network slicing in 5G and beyond networks.
