A radio access network (RAN) control unit for determining a functional operation of a dynamic small cell, in particular an unplanned small cell, a nomadic node or a relay, in a radio communication network is disclosed. The radio communication network includes at least one network slice associated with at least one user equipment (UE) and at least one radio channel connecting the at least one UE to the radio communication network. The RAN control unit includes a processor configured to determine a functional operation of the dynamic small cell (DSC) based on information based on channel measurements of the at least one radio channel and/or requirement information of the at least network one slice, and/or estimated or measured performance of the RAN, and/or location information of the DSC.
