FOXCONN, Taiwan and 5Gmobile research laboratory (http://5Gmobile.fel.cvut.cz), department of Telecommunication Engineering, CTU in Prague work together on development of solutions for splitting of MAC functions between virtualized control function in radio access network (base-band unit) and remote radio heads. The delivered algorithm should enable dynamic communication control with all benefits commonly expected from cloud controlled-RAN (C-RAN) in future mobile networks, i.e., low cost of RAN, low delay and high capacity. The project targets both to design theoretical solutions for functional splitting and its testing and validation in a mobile network.
