User equipments (UEs) may be scheduled by, in a cell, determining relative priorities of data radio bearers (DRBs), each DRB associated with an active UE. A limit is established dividing radio resources available for allocation in the cell during a scheduling period into at least a first limited portion and a second remaining portion. According to the determined relative priorities: a) up to the first limited portion of the radio resources are allocated to only the DRBs that have a guaranteed bit rate (GBR), and thereafter b) the second remaining portion of the radio resources are allocated to only the DRBs which have not been fully allocated from the first limited portion. In carrier aggregation the radio resources are allocated in turn in each different cell per step a) and thereafter in turn in each different cell per step b).
