On the capacity of cloud radio access networks
2017 IEEE International Symposium on Information Theory (ISIT), 2017Uplink and downlink cloud radio access networks are modeled as two-hop K-user L-relay networks, whereby small base-stations act as relays and are connected to a central processor via orthogonal links of finite capacity. Simplified versions of noisy network coding and distributed decode-forward are used to establish inner bounds on the capacity region ...

Virtualization and Orchestration of Radio Access Network
2018 IEEE International Conference on Communication Systems (ICCS), 2018This paper discusses orchestration of RAN systems implemented with virtualization. The 5G mobile communication system should have one flexible network structure that can accommodate a wide variety of services in multiple industries. This paper presents the design and implementation results of a flexible RAN system with NFV reference model.

Radio Access Network Emulator for LTE
2009 IEEE International Conference on Wireless and Mobile Computing, Networking and Communications, 2009In this paper we present an LTE RAN (Radio Access Network) Emulator based on a new method for mobile channels modeling. The new method is then used to model the OFDMA Downlink of LTE (Long Term Evolution) link level performance under 16-QAM hierarchical modulation.

Improving restorability in radio access network
GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004In the past, wireless network reliability issues have received limited attention. Previously proposed solutions have focused on protection against base station failures, which may require significantly more base stations than necessary. Actual data from wireless carriers suggest that problems in the backhaul are the uttermost reliability problems faced,

Radio access technology classification for cognitive radio networks
2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2013In spectrum bands where spectrum sharing is allowed by national regulators, radio access technology recognition is an important technique for reducing interference and facilitating cooperation among cognitive radios. Unlicensed users (secondaries) need to be able to differentiate between transmissions of licensed users (primaries) and other unlicensed ...

Radio Access Network Slicing in 5G
2017Network slicing is one of the key technologies for 5th-Generation (5G). It enables operators to construct network slices with similar qualities as dedicated stand-alone networks, but to realize them on a common physical platform. Meanwhile, the isolation among logical network slices can keep them from the negative impacts of other network slices.

Optimizing Access Radio in Multi-Radio Mesh Network
2009 IEEE International Conference on Communications, 2009This paper discusses a hierarchical multi-radio mesh network, where the normal clients associate with the mesh AP through the access radio and then the mesh APs communicate with each other via the mesh radio. While most of the existing studies focus on the performance issue for the mesh nodes communication with the mesh radio, in this paper, we argue ...

5G and Radio Access Network architecture
2017 14th International Conference on Telecommunications (ConTEL), 2017Radio access technologies for mobile broadband have evolved effectively to provide connectivity to billions of subscribers and things. Current Radio Access Network architecture is undergoing a transformation to increase deployment flexibility and network dynamicity, so that networks will be able to meet the performance requirements demanded by ...

IEEE Wireless Communications and Networking Conference, 2005, 2005
The paper describes a case study in which the current UMTS radio access network (UTRAN, Release 3) is compared to a modified architecture where radio network controller (RNC) functionality is completely moved to the node B. The new architecture better suits IP principles.

Radio resource calendaring in cloud-based radio access networks
2018 Wireless Days (WD), 2018Bandwidth calendaring refers to the possibility of shifting some bulk data transfers, typically of large size with less stringent real-time constraint, to the moments when the network is less congested. In this paper, we exploit calendering in radio resource allocation in Cloud-based Radio Access Networks (C-RANs), where calendaring naturally fits the ...
