A network infrastructure for a wireless communication system is disclosed. The infrastructure comprises a fronthaul network, an RRH pool, a radio service chain (RSC). The RSC is coupled to the fronthaul network and the RRH pool for allocating the RRH resources. The RSC comprises an orchestrator and a remote radio head (RRH) controller. The orchestrator is used for receiving a radio resource request from the at least one C-RAN and converting the radio resource request into a RRH specific command. The RRH controller is used for slicing the RRH resources to create virtual RRHs according to the radio resource request.
