Optimal load balancing in cloud radio access networks
2015 IEEE Wireless Communications and Networking Conference (WCNC), 2015Cloud radio access network (CRAN) has been seen as an effective means to address the challenges faced by cellular radio networks, such as high capital expenditure and operating expense, high energy consumption and low spectral efficiency. Especially, CRAN has the potential to equip a cellular network with the load-balancing capability to cope with the ...

Multi-resource allocation in cloud radio access networks
2017 IEEE International Conference on Communications (ICC), 2017Computational resource allocation is a critical issue for the baseband unit (BBU) pool in a cloud radio access network (C-RAN). There are multiple resources in a BBU, including CPU, memory, disk, etc. The virtual machines (VMs) have diverse requirements along these resources to handle the baseband signal processing of corresponding remote radio units ...

Collaborative hierarchical caching in cloud radio access networks
2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2017To deal with the severe challenge from explosively increasing mobile users' multimedia service requests in mobile networks, introducing cloud-based computing platform and content caching into radio access networks (RANs) has become an effective emerging technique. In this paper, we propose a collaborative hierarchical caching framework in cloud RANs (C-

Resource sharing in heterogeneous cloud radio access networks
IEEE Wireless Communications, 2015Heterogeneous cloud radio access networks incorporate the heterogeneous network and cloud radio access network concepts for next generation cellular networks. H-CRANs exploit the heterogeneity of macro and small cells from HetNets, enabling cellular networks to achieve higher spectral efficiency. Meanwhile, concepts from C-RANs involving baseband units

Robust distributed compression for cloud radio access networks
2012 IEEE Information Theory Workshop, 2012This work studies distributed compression for the uplink of a cloud radio access network, where multiple multi-antenna base stations (BSs) communicate with a central unit, also referred to as cloud decoder, via capacity-constrained back-haul links. Distributed source coding strategies are potentially beneficial since the signals received at different ...
