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.

RRH selection and load balancing through Dynamic BBU-RRH Mapping in C-RAN
2019 IEEE Canadian Conference of Electrical and Computer Engineering (CCECE), 2019Cloud radio access network (C-RAN) is a novel architecture that supports the massive growth in traffic of the mobile network. Still, the connection blocking in the C-RAN network may occur due to two main reasons. The first one is not an optimal selection of the radio resource heads (RRHs) to serve the user demands. The second one is not optimal mapping

BBU-RRH switching schemes for centralized RAN
7th International Conference on Communications and Networking in China, 2012Mobile data traffic has been increasing at a rapid pace over the past few years due to the rise of both smartphones and tablets. Small cell deployments are one of the most effective ways to increase system capacity by improving the spatial reuse of radio resources for the explosive increase in traffic loads.

RRH clustering in cloud radio access networks
2015 International Conference on Applied Research in Computer Science and Engineering (ICAR), 2015Cloud Radio Access Network (C-RAN) offers an evolution in base stations architecture. The base station is broken down into a Base Band Unit (BBU) and a Remote Radio Head (RRH). While BBUs are pooled in a single geographical point, RRHs are distributed across multiple sites. In conventional architectures, a one-to-one logical mapping exists between BBUs

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.

Secondary Serving Cell Selection for Heterogeneous Network with RRH Deployment
2011 IEEE International Conference on Communications Workshops (ICC), 2011Carrier Aggregation (CA) is one of the important technologies to further improve the capacity of Long Term Evolution Advanced (LTE-A). When CA is conducted, a User Equipment (UE) will firstly select a Primary Serving Cell (PCell) for mobility support and then add Secondary Serving Cells (SCell) for higher experienced data rate.

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 ...
