Resource-Optimal Licensed-Assisted Access in Heterogeneous Cloud Radio Access Networks With Heterogeneous Carrier Communications

IEEE Transactions on Vehicular Technology, 2016
To support a tremendous amount of traffic demands via wireless access in 2020 and beyond, limited bandwidth of the licensed bands has been a major obstacle to boosting further the capacity of wireless services. To fundamentally break through this predicament, an emerging technology known as heterogeneous carrier communications has been launched into ...

Ergodic Rate Analysis for User Access in Downlink Heterogeneous Cloud Radio Access Networks

2015 IEEE Global Communications Conference (GLOBECOM), 2014
Characterizing user access methods in heterogeneous cloud radio access networks (H-CRANs)is critical for performance optimization. Different from the user access in cloud radio access networks, the inter-tier interference from macro base station has a great impact on user access in H-CRANs.

Software-defined handover decision engine for heterogeneous cloud radio access networks

Computer Communications, 2018
Abstract The current telecommunication infrastructure is reaching its limits, no longer able to cope with the ever-growing number of connected devices and data traffic summed to the future QoS demand of 5G. To overcome such limitations, the Heterogeneous Cloud Radio Access Network (H-CRAN) has been considered as a promising architecture that includes

Resource Allocation in Heterogeneous Cloud Radio Access Networks: A Workload Balancing Perspective

2015 IEEE Global Communications Conference (GLOBECOM), 2014
Heterogeneous cloud radio access networks (H-CRANs) have been proposed as a promising architecture for providing high energy efficiency, high spectral efficiency and high data rate at low cost. In this paper, we develop a novel resource allocation scheme among macro base stations (BSs) and remote radio heads (RRHs) for the H-CRANs.

Coordinated multi-point joint transmission evaluation in heterogenous cloud radio access networks

2017 Iranian Conference on Electrical Engineering (ICEE), 2017
In this paper, the effect of applying coordinated multi-point joint transmission (CoMP-JT) in system performance of 5G heterogeneous cloud radio access networks (H-CRANs) is investigated. For this purpose, two simple user-centric and network-centric clustering methods are presented and the amount of obtained CoMP gain in each of these dynamic-formed ...

Dynamic resource optimization with congestion control in heterogeneous cloud radio access networks

2014 IEEE Globecom Workshops (GC Wkshps), 2014
The heterogeneous cloud radio access networks (H-CRANs) are presented in this paper as a promising new paradigm for future heterogeneous converged networks. To maintain low traffic queue congestion and make the sum utility of average throughput arbitrarily close to the optimum, the dynamic optimization problem of traffic admission control ...

Joint Power Allocation and Beamforming in Heterogeneous Cloud Radio Access Networks

2019 IEEE 4th International Conference on Computer and Communication Systems (ICCCS), 2019
In this paper, resource allocation for heterogeneous cloud radio access network (HC-RAN) network is investigated. By maximizing the sum rate of all the users in HC-RAN under the power constraints of macro base station (MBS) and remote radio heads (RRHs), the MBS beamforming vectors and RRHs transmit power are jointly optimized.
