Remote radio heads and the evolution towards 4G networks [PDF]

, 2009
Distributed base stations with remote radio head (RRH) capability greatly help mobile operators to resolve cost, performance, and efficiency challenges when deploying new base stations on the road to fully developed 4G networks. Multi-mode radios capable

Spectrally Efficient Fronthaul Architectures For A Cost-effective 5g C-ran

, 2017
In 5G wireless systems, centralized RAN (C-RAN) is an architectural choice where the signal waveforms received by Remote Radio Heads (RRH) are transparently forwarded to base band units (BBU), in many cases using an optical fronthaul.

Power-and rate-adaptation improves the effective capacity of C-RAN for Nakagami-m fading channels

We propose a quality-of-service (QoS) driven power-and rate-adaptation scheme for wireless cloud radio access networks (C-RAN), where each radio remote head (RRH) is connected to the baseband unit (BBU) pool through high-speed optical links.

RRH selection and load balancing through Dynamic BBU-RRH Mapping in C-RAN

2019 IEEE Canadian Conference of Electrical and Computer Engineering (CCECE), 2019
Cloud 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

Joint User Association and RRH Clustering in Cloud Radio Access Networks

2018 Tenth International Conference on Ubiquitous and Future Networks (ICUFN), 2018
Cloud Radio Access Network (C-RAN) has emerged as a promising network architecture for 5G cellular networks. The conventional base station is broken down into a Remote Radio Head (RRH) and a Base Band Unit (BBU). The RRHs are geographically scattered across multiple sites, whereas the BBUs are sheltered in a data center.

RRH clustering in cloud radio access networks

2015 International Conference on Applied Research in Computer Science and Engineering (ICAR), 2015
Cloud 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
