Methods for allocating spectrum resources among a plurality of devices in a wireless communication network are disclosed. In one aspect, an estimated number of resource blocks required by a first device and an estimated number of resource blocks required by a second device are determined. The required number of resource blocks may be determined by considering the number of resource blocks that would be necessary to empty the buffer of a first device and/or determining the number of resource blocks that would be sufficient to cause the first device to become power limited. These estimates may then be used to calculate first and second utilization weights, which can in turn be used to calculate scheduling entity weights for a plurality of scheduling entities, such as UEs in the communication network. Allocation may be based on the scheduling entity weights, utilization weights, and/or the required number of resource blocks.
