On the capacity of cloud radio access networks

2017 IEEE International Symposium on Information Theory (ISIT), 2017
Uplink 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 ...

Improving restorability in radio access network

GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004
In 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,

The Slice Is Served: Enforcing Radio Access Network Slicing in Virtualized 5G Systems

IEEE Conference on Computer Communications, 2019
The notions of softwarization and virtualization of the radio access network (RAN) of next-generation (5G) wireless systems are ushering in a vision where applications and services are physically decoupled from devices and network infrastructure.

Radio Access Network Slicing in 5G

2017
Network 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.

Virtualization and Orchestration of Radio Access Network

2018 IEEE International Conference on Communication Systems (ICCS), 2018
This 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.
