Intelligent Resource Scheduling for 5G Radio Access Network Slicing

Radio Access Network Resource Slicing for Flexible Service Execution

Network slicing is a key enabler for the serviceoriented 5G vision, that aims to satisfy various per-service requirements. Unlike core network slicing, radio access network (RAN) slicing is still at its infancy, with several works just starting to investigate the challenges and potentials to enable a mutli-tenant, multi-service RAN. One of the major challenges in RAN slicing is to provide diffe...

An adaptive 5G multiservice and multitenant radio access network architecture

This article provides an overview on objectives and first results of the Horizon 2020 project 5G NOvel Radio Multiservice adaptive network Architecture (5GNORMA). With 5G NORMA, leading players in the mobile ecosystem aim to underpin Europe’s leadership position in 5G. The key objective of 5G NORMA is to develop a conceptually novel, adaptive and future-proof 5G mobile network architecture. Thi...

Towards 5G Network Slicing over Multiple-Domains

Cross-layer design for radio resource allocation based on priority scheduling in OFDMA wireless access network

The orthogonal frequency-division multiple access (OFDMA) system has the advantages of flexible subcarrier allocation and adaptive modulation with respect to channel conditions. However, transmission overhead is required in each frame to broadcast the arrangement of radio resources to all mobile stations within the coverage of the same base station. This overhead greatly affects the utilization...

End-to-end Network Slicing for 5G Mobile Networks

The research and development (R&D) and the standardization of the 5th Generation (5G) mobile networking technologies are proceeding at a rapid pace all around the world. In this paper, we introduce the emerging concept of network slicing that is considered one of the most significant technology challenges for 5G mobile networking infrastructure, summarize our preliminary research efforts to ena...
