Resource Optimization in Heterogeneous Cloud Radio Access Networks
IEEE Communications Letters, 2018This letter tackles the problem of sum-rate maximization via joint user association and power allocation in heterogeneous cloud radio access networks, while guaranteeing the quality-of-service requirements of all users. A generalized Stackelberg game is applied to this problem with the coupled strategy set of power allocation, and a centralized ...

Resource Allocation in Heterogeneous Cloud Radio Access Networks: Advances and Challenges
IEEE Wireless Communications, 2015Base station densification is increasingly used by network operators to provide better throughput and coverage performance to mobile subscribers in dense data traffic areas. Such densification is progressively diffusing the move from traditional macrocell base stations toward heterogeneous networks with diverse cell sizes (e.g., microcell, picocell ...

Balancing Backhaul Load in Heterogeneous Cloud Radio Access Networks
IEEE Wireless Communications, 2015Inspired 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

Collaborative radio access of heterogeneous cloud radio access networks and edge computing networks
2016 IEEE International Conference on Communications Workshops (ICC), 2016Although the technical merits of the heterogeneous cloud radio access networks (H-CRAN) architecture have been well demonstrated in terms of data rate enhancement and ubiquitous wireless service provisioning, solely relying on the H-CRAN may not be sufficient to further support full automation and everything-to-everything (X2X) connection for the next ...

Resource sharing in heterogeneous and Cloud Radio Access Networks
2012 IV International Congress on Ultra Modern Telecommunications and Control Systems, 2012This 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 ...

Hierarchical cooperation in heterogeneous cloud radio access networks
2016 IEEE International Conference on Communications (ICC), 2016Heterogeneous 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, 2015The 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.

Wireless multicast for cloud radio access network with heterogeneous backhaul
2017 51st Asilomar Conference on Signals, Systems, and Computers, 2017Cooperative 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.
