Comp Transmission in Cloud Radio Access Networks
2015 IEEE Globecom Workshops (GC Wkshps), 2015Coordinated multi-point (CoMP) is an efficient technique to increase cell-edge coverage probability and throughput in cloud radio access network (C- RAN). In this paper, we develop a tractable framework to analytically evaluate the performance of two typical CoMP schemes, namely, zero-forcing beamforming(ZFBF) and non-coherent joint transmission (NC-JT)

On Fairness Optimization for Cloud Radio Access Networks
2019 IEEE 24th International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD), 2019Cloud Radio Access Network (C-RAN) has been proposed as an emerging technology to meet the ever-increasing data traffic demands in wireless networks with flexibility in resource management and network operation. Due to the physical limitation for network providers, resource allocation is an important topic in C-RAN.

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 ...

A network slicing prototype for a flexible cloud radio access network
2018 15th IEEE Annual Consumer Communications & Networking Conference (CCNC), 2018The next 5G infrastructure is expected to serve a multitude of services with heterogeneous requirements, which might be potentially managed by multiple Mobile Virtual Network Operators (MVNOs) that share the same network infrastructure. The new emerging technologies, such as i) Software Defined Networking (SDN), ii) Network Function Virtualization (NFV)

Rate Aware Network Codes for Cloud Radio Access Networks
IEEE Transactions on Mobile Computing, 2019Cloud radio access networks (C-RAN) gained much attention thanks to their abilities in mitigating interference and providing high data rates by coordinating multiple Remote Radio Heads (RRHs). This paper considers the use of rate aware instantly decodable network coding (RA-IDNC) as a mean to accelerate the broadcast of a set of messages to a set of ...

Performance Evaluations of Cloud Radio Access Networks
2017With the skyrocketing amount of data communications, traditional Radio Access Networks (RANs) infrastructure suffers from high capital and operating expenditures. Many countries and mobile network operators, therefore, propose software-defined radio access networks for centralized management, and further apply cloud computing technologies into cellular

Location-aware network operation for cloud radio access network
2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017One of the major challenges in effectively operating a cloud radio access network (C-RAN) is the excessive overhead signaling and computation load that scale rapidly with the size of the network. In this paper, the exploitation of location information of the mobile devices is proposed to address this challenge. We consider an approach in which location-
