“…In the next generation of mobile networks, the full virtualization of CU and DU, and the partial/full virtualization of RU, can lead to a number of advantages, such as increased performance of the RAN architecture, deployment of RAN slice subnets, decreased network expenditure, simplified operations and management of the network, etc. [112]. We, thus, firmly believe that further studies are needed to address the virtualization of RU functionalities towards a virtualized and slicing-aware RAN of the 6G mobile networks [113].…”

“…Each type of RAN slice subnet fulfills the service requirements of a singe type of use case of a single tenant. Nevertheless, there is a large number of vertical industries -such as automobile, manufacturing, power grid, and others -which are consisting of multiple use cases [112]. Providing RAN slice subnets for multiple use cases consisting of vertical industries is a crucial research problem that is needed to be addressed in the next generation of mobile networks.…”

As of today, the fifth generation (5G) mobile communication system has been rolled out in many countries and the number of 5G subscribers already reaches a very large scale. It is time for academia and industry to shift their attention towards the next generation. At this crossroad, an overview of the current state of the art and a vision of future communications are definitely of interest. This article thus aims to provide a comprehensive survey to draw a picture of the sixth generation (6G) system in terms of drivers, use cases, usage scenarios, requirements, key performance indicators (KPIs), architecture, and enabling technologies. First, we attempt to answer the question of "Is there any need for 6G?" by shedding light on its key driving factors, in which we predict the explosive growth of mobile traffic until 2030, and envision potential use cases and usage scenarios. Second, the technical requirements of 6G are discussed and compared with those of 5G with respect to a set of KPIs in a quantitative manner. Third, the state-of-the-art 6G research efforts and activities from representative institutions and countries are summarized, and a tentative roadmap of definition, specification, standardization, and regulation is projected. Then, we identify a dozen of potential technologies and introduce their principles, advantages, challenges, and open research issues. Finally, the conclusions are drawn to paint a picture of "What 6G may look like?". This survey is intended to serve as an enlightening guideline to spur interests and further investigations for subsequent research and development of 6G communications systems.

“…Similarly, the work in [27] elaborates on how the proposals described in [26] address the challenges of provisioning network slice instances that support multiple use cases at the vertical level. Both works focus on providing network slices, but in [27], the authors integrate the 3GPP network slicing management system into the orchestration architecture.…”

Network slicing is a key element in 5G networks. It allows a mobile network operator (MNO) to offer multiple logical networks tailored to the requirements of different industry verticals over a shared infrastructure. From the point of view of an MNO, a mobile virtual network operator (MVNO) is a particular type of vertical network requiring not only the provision of logical networks with specific infrastructure resources but also customized management capabilities to allow the MVNO to offer network slice-based services to its clients over the infrastructure of multiple MNOs. However, the lack of flexibility to provide a customized and efficient network slice management system per tenant under the current proposals of the 3rd Generation Partnership Project (3GPP) and European Telecommunications Standards Institute (ETSI) limits the possibilities of MVNOs. This paper addresses this requirement by proposing a novel virtualized multidomain and multiclient orchestration system aligned with the functionalities of the network slicing management framework proposed by the 3GPP and ETSI. In particular, there are three contributions of this paper: (i) an extended service-based architecture is designed to provide an isolated management system to different MVNOs; (ii) a novel high-level slice instance template is defined to specify management and isolation requirements supporting network slicing as a service model; and (iii) finally, a teleoperated driving use case is described to showcase how our proposal provides an MVNO with an independent management system to orchestrate several network slices in cross-domain environments.
