An apparatus for use in a radio aggregation unit (RAU) of a cloud radio access network (Cloud-RAN or C-RAN), the cloud-RAN including a radio cloud center (RCC) and a plurality of radio remote systems (RRS) coupled to the RCC, wherein each RRS comprises an RAU coupled to a plurality of Remote Radio Units (RRUs) is disclosed. The apparatus comprises an input circuit configured to receive a first scheduling result from the RCC and a scheduling circuit configured to generate a second scheduling result for scheduling the one or more UEs in the coverage area of the RAU. Further, the apparatus comprises a processing circuit configured to selectively schedule a select UE from one or more UEs in the coverage area of the RAU, based on the first scheduling result from the RCC or the second scheduling result or an integration of the first scheduling result and the second scheduling result, based on a predetermined threshold associated with a receipt time of the first scheduling result from the RCC at the RAU.
