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 ...

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).

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.

Modelling the energy efficiency of Heterogeneous Cloud Radio Access Networks

2015 International Conference on Emerging Technologies (ICET), 2015
Cellular network performance is measured by its spectral and energy efficiency, with power consumption an important key to success for the upcoming heterogeneous (HetNet) communication system generations. The proposed models presented in this paper, component, linear, and parameterized power models, analyse and evaluate the power consumption ...

Delay Guaranteed Network Association for Mobile Machines in Heterogeneous Cloud Radio Access Network

IEEE Transactions on Mobile Computing, 2018
In the heterogeneous cloud radio access network (H-CRAN), which consists of multiple access points (APs) providing smaller coverage and a high power node (HPN) providing ubiquitous coverage, the mobile machines can connect to multiple APs and HPN by coordinated multi-point transmission (CoMP) concurrently to achieve ultra-reliable and low-latency ...
