RRH and small cells — The implications for spectrum sharing
2015 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN), 2015This paper considers the implications of different infrastructure options on a spectrum sharing scenario in cellular networks, featuring a mixture of macro cells and low-power nodes (LPNs). Our aim is to provide a systematic approach to spectrum sharing.

Short Survey on Clustering Techniques for RRH in 5G networks
2018 Seventh International Conference on Communications and Networking (ComNet), 2018Cloud Radio Access Network (C-RAN) is a promising solution to meet the 5GGP requirements for 5G Networks. The C-RAN is based on the idea of splitting the conventional eNB into two parts: the Remote Radio Head (RRH) and the Base Band Unit (BBU). The RRH will be responsible for the RF transmission and it will be densified to enhance the capacity of the ...

QoS-aware Joint RRH activation and clustering in cloud-RANs
2016 IEEE Wireless Communications and Networking Conference, 2016Cloud Radio Access Networks (Cloud-RAN) promise to leverage cloud computing capabilities to enhance the quality and coverage of wireless networks. A dense network of remote radio heads (RRHs) ensures less attenuation at the receiver side. However, two drawbacks are associated with such dense network: the first is the high energy consumption associated ...

Centralized and distributed RRH clustering in Cloud Radio Access Networks
2017 IEEE Symposium on Computers and Communications (ISCC), 2017Cloud Radio Access Network (C-RAN) is a promising technology to improve user quality of service and reduce network capital and operating costs. The key concept behind C-RAN is to break down the conventional base station into a Base Band Unit (BBU) and a Remote Radio Head (RRH), and to pool BBUs from multiple sites into a single geographical point ...

Performance Study on the ECID Positioning Enhancement in LTE-A Het-Net with RRH
2015 IEEE 82nd Vehicular Technology Conference (VTC2015-Fall), 2015As the development of mobile networks, the positioning technologies meet some challenges. Some positioning technologies, such as enhanced cell identity (ECID) and observed time difference of arrival (OTDOA) in LTE, need enhancement for positioning in LTE-A heterogeneous network (het-net) scenarios to improve positioning accuracy.

ARIES-RRH: restricted repeating of history in the ARIES transaction recovery method
[1991] Proceedings. Seventh International Conference on Data Engineering, 2002A method called ARIES-RRH (algorithm for recovery and isolation exploiting semantics with restricted repeating of history) is presented which is a modified version of the ARIES transaction recovery and concurrency control method implemented to varying degrees in Starburst, QuickSilver, the OS/2 Extended Edition Database Manager, DB2 V2, Workstation ...

Joint RRH selection and beamforming in distributed antenna systems with energy harvesting
2017 International Conference on Computing, Networking and Communications (ICNC), 2017To reduce the transmission power while maintaining quality of service requirements of users, more remote radio heads (RRHs) should be active, and this in turn increases the circuit power in the distributed antenna systems with simultaneous wireless information and power transferring. Yet, the above procedures may lead to an unbalanced power consumption

Traffic Density-Based RRH Selection for Power Saving in C-RAN
IEEE Journal on Selected Areas in Communications, 2016Cloud radio access network (C-RAN) is deemed as a promising architecture to meet the exponentially increasing traffic demand in a mobile network. However, it needs a huge amount of transport capacity between the remote radio heads (RRHs) and the baseband unit pool.
