Title:Elastic Service Scaling in Cloud Radio Access Network
Abstract:Cloud radio access network (C-RAN) is emerging as a potential alternative for the next generation RAN by merging RAN and cloud computing. Differing from the intensive study on C-RAN from the aspect of wireless transmission, in this talk, we describe two recent works on C-RAN from the aspect of cloud computing. Specifically, cloud computing brings the feature of elastic service scaling into the RAN, which means the amount of computation resources in C-RAN baseband unit (BBU) pool can be dynamically adjusted. Therefore, effectively managing and dispatching those computation resources in C-RAN becomes a critical problem.
In this talk, we consider the joint computation resource allocation and sparse beamforming problems, under two different C-RAN scenarios, i.e., idealized scenario and practical scenario, respectively. We also discuss some potential future research topics in the end of this talk.
