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).

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.

Reducing power consumption by dynamic BBUs-RRHs allocation in C-RAN

2017 25th Telecommunication Forum (TELFOR), 2017
In this paper, a new power consumption model for Cloud Radio Access Network (C-RAN) architecture based on virtualization of Base Band Unit (BBU) has been introduced. Moreover, it is proposed a Host Server (HS) in the BBU pool that hosts a Modified Best Fit Decreasing (MBFD) algorithm to optimize reconfiguration of BBUs to proper Remote Radio Heads ...

Secondary Serving Cell Selection for Heterogeneous Network with RRH Deployment

2011 IEEE International Conference on Communications Workshops (ICC), 2011
Carrier 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.

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 ...

C-RAN αλγόριθμος υλοποίησης RRH σε BBU

2018
In recent years there has been a rapid increase in the load served by mobile telephony due to the widespread use of smartphones and tablets. One of the most effective methods in cellular systems, to serve the ever increasing volume of data, is to reduce the radius of each cell. In this way, spatial reuse of wireless resources is achieved.
