Hierarchical cooperation in heterogeneous cloud radio access networks

2016 IEEE International Conference on Communications (ICC), 2016
Heterogeneous cloud radio access networks (H-CRAN), which combines the benefits of cloud radio access radio networks (C-RAN) and heterogeneous networks (HetNets), is an emerging technology to achieve high data transmission rates in 5G cellular networks.

Power Model for Heterogeneous Cloud Radio Access Networks

2015 IEEE International Conference on Data Science and Data Intensive Systems, 2015
The cellular network performance is measured by its spectral and energy efficiency. Since the power consumption is an important key success for the upcoming heterogeneous (HetNet) communication system generations, component, linear, and parameterized power models are presented in this paper.

Resource sharing in heterogeneous and Cloud Radio Access Networks

2012 IV International Congress on Ultra Modern Telecommunications and Control Systems, 2012
This paper analyzes performance of cellular systems with shared resources, where the network with overlapping cells is modeled as a circuit switched network with direct routing. The influence of the degree of sharing, represented by cell overlap percentage, on the call blocking probability is investigated for three scenarios, including cells with ...

Balancing backhaul load in heterogeneous cloud radio access networks

IEEE Wireless Communications, 2015
Inspired by the explosive growth of mobile data traffic, the severe inter-tier interference, and the fierce competition between the total cost of ownership and revenues for mobile operators, the heterogeneous cloud radio access network (H-CRAN) has been proposed as one of the most prominent ways to handle these challenges. The key idea of the H-CRAN is

Cooperation-Based Interference Mitigation in Heterogeneous Cloud Radio Access Networks

ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019
In this paper, we propose a cooperation framework in heterogeneous cloud radio access networks (H-CRANs) to mitigate inter-tier interference. Specifically, small cell remote radio head (S-RRH) acts as the cognitive relay for multiple macrocell users (MUEs) which are primary users, and obtains a fraction of time slot from multiple MUEs as a reward ...

Wireless multicast for cloud radio access network with heterogeneous backhaul

2017 51st Asilomar Conference on Signals, Systems, and Computers, 2017
Cooperative communication in which multiple base-stations (BSs) jointly transmit to mobile users is a major advantage of the cloud radio-access network (C-RAN) architecture. This paper considers the use of wireless multicast for sharing user messages at multiple BSs in the C-RAN backhaul for cooperation purpose.

Energy Efficient Resource Allocation in Heterogeneous Cloud Radio Access Networks

2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017
Energy harvesting is becoming an attractive option of energy supply for wireless networks as it can effectively reduce capital expenditure (CAPEX) and operational expenditure (OPEX). In this paper, an energy efficient radio resource optimization algorithm is proposed for a two-tier heterogeneous cloud radio access network (H-CRAN) where macro cells are

CoMP Transmission in Downlink NOMA-Based Heterogeneous Cloud Radio Access Networks

IEEE Transactions on Communications, 2020
In this paper, we investigate the integration between the coordinated multipoint (CoMP) transmission and the non-orthogonal multiple access (NOMA) in downlink heterogeneous cloud radio access networks (H-CRANs). In H-CRAN, low-power high-density small remote radio heads (SRRHs) are underlaid by high-power low-density macro RRH (MRRH).
