Spectrum sensing and resource allocation for 5G heterogeneous cloud radio access networks [PDF]
IET Communications, 2022 Abstract In this paper, the problem of opportunistic spectrum sharing for the next generation of wireless systems empowered by the cloud radio access network (C‐RAN) is studied. More precisely, low‐priority users employ cooperative spectrum sensing to detect a vacant portion of the spectrum that is not currently used by high‐priority ...

Contract-Based Interference Coordination in Heterogeneous Cloud Radio Access Networks [PDF]
IEEE Journal on Selected Areas in Communications, 2015 Heterogeneous cloud radio access networks (HCRANs) are potential solutions to improve both spectral and energy efficiencies by embedding cloud computing into heterogeneous networks (HetNets). The interference among remote radio heads (RRHs) can be suppressed with centralized cooperative processing in the base band unit (BBU) pool, while the intertier ...

Robust Beamforming with Pilot Reuse Scheduling in a Heterogeneous Cloud Radio Access Network [PDF]
IEEE Transactions on Vehicular Technology, 2018 This paper considers a downlink ultra-dense heterogeneous cloud radio access network (H-CRAN) which guarantees seamless coverage and can provide high date rates. In order to reduce channel state information (CSI) feedback overhead, incomplete inter-cluster CSI is considered, i.e., each remote radio head (RRH) or macro base station (MBS) only measures ...

Green Heterogeneous Cloud Radio Access Networks: Potential Techniques, Performance Trade-offs, and Challenges [PDF]
IEEE Communications Magazine, 2017 As a flexible and scalable architecture, heterogeneous cloud radio access networks (H-CRANs) inject strong vigor into the green evolution of current wireless networks. But the brutal truth is that energy efficiency (EE) improves at the cost of other indexes such as spectral efficiency (SE), fairness, and delay.

System architecture and key technologies for 5G heterogeneous cloud radio access networks [PDF]
IEEE Network, 2015 Compared with the fourth generation (4G) cellular systems, the fifth generation wireless communication systems (5G) are anticipated to provide spectral and energy efficiency growth by a factor of at least 10, and the area throughput growth by a factor of at least 25.
