Radio access technology classification for cognitive radio networks

2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2013
In 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 ...

Optimizing Access Radio in Multi-Radio Mesh Network

2009 IEEE International Conference on Communications, 2009
This 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 ...

Comparison of signaling performance in the UMTS radio access network and a merged radio access network architecture

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), 2018
Bandwidth 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 ...

Lost Capacity of the UMTS Radio Access Network

Wireless Personal Communications, 2006
The theoretical capacity models for the downlink and the uplink of the UMTS radio access network have been researched ever since the UMTS started to be considered. However, they were often based on idealistic assumptions and addressed a static situation. Because of that results were too optimistic.
