Optical X-haul for 5G /6G: Design and Deployment Standpoint

In this paper, we review the work we have carried out in the investigation of the transport network in a hybrid fiber-wireless system to cater for the next generation wireless networks. We have demonstrated advanced coordination functionality in the physical layer to enable coordination between remote radio heads. We have also devised an optimization framework to jointly optimize the wireless and optical network that minimizes the deployment cost. We conclude the paper by providing insights into a reconfigurable optical architecture that can be used to support wireless networks of 6G and beyond.
