Passive, lightweight thermal solutions for Remote Radio Head (RRH) electronics

2008 11th Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems, 2008
The ever-increasing size of wireless networks has led to the development of new base station architectures. Traditional telecommunication base stations have baseband and radio-frequency (RF) components mounted inside an air-conditioned hut with co-axial cables transmitting signals to remote antennas.

Optical RRH working in an all-optical fronthaul network

Photonics, Devices, and Systems VII, 2017
The paper presents an example of an optical RRH (Remote Radio Head) design, which is equipped with photonic components for direct connection to an all-optical network. The features that can be fulfilled by an all-optical network are indicated to support future 5G mobile networks.

Energy-Efficient RRH Sleep Mode for Virtual Radio Access Networks

GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017
Network functions virtualization (NFV) has become a strategic tool that facilitates mobile network resource sharing and management by mobile network operators (MNOs). Cloud radio access network (C- RAN) virtualization allows agglomeration of multiple radio access networks (RANs) functions in a single resource pool.

Robotic-Assisted Radical Hysterectomy (RRH) as Nerve-Sparing Procedure

2017
Nerve-sparing radical hysterectomy (NSRH) is procedure to preserve pelvic autonomic nerves and provides ealier return of bladder function, better vaginal blood flow, and fewer symptoms related to anorectal function. Pelvic autonomic nerves compose of superior hypogastric plexus, pelvic splanchnic nerves, sacral splanchnic nerves, inferior hypogastric ...

Short Survey on Clustering Techniques for RRH in 5G networks

2018 Seventh International Conference on Communications and Networking (ComNet), 2018
Cloud 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 ...

RRH clustering in cloud radio access networks with re-association consideration

2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018
Cloud Radio Access Network (C-RAN) is an evolution in the base station architecture, mainly composed of two elements: The Base Band Unit (BBU) and the Remote Radio Head (RRH). This new architecture separates the two elements (the BBUs from RRHs), to group all the BBUs into one cloud, while RRHs are distributed across many sites.

Joint RRH Selection and Power Allocation forEnergy-Efficient C-RAN Systems

2018 Al-Mansour International Conference on New Trends in Computing, Communication, and Information Technology (NTCCIT), 2018
This paper addresses the energy efficiency (EE) based Remote Radio Heads (RRHs) selection problem in cloud radio-access network. In specific, a low-complexity 2-stage iterative algorithm is developed for this purpose by jointly employing the coordinated multi-point (CoMP) and user-clustering techniques. The first stage of the algorithm comprises of two

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.

Multi-Objective Optimization for RRH Clustering in Cloud Radio Access Networks

2018 International Conference on Computer and Applications (ICCA), 2018
Cloud Radio Access Network (C-RAN) has been proposed as a potential solution to reduce network power consumption, while providing acceptable quality of service (QoS). In this context, the conventional base station is separated into a Base Band Unit (BBU) and a Remote Radio Head (RRH).
