Abstract
A method and apparatus for uplink scheduling in the presence of narrowband interference on, for instance, a long term evolution (LTE) network. The uplink scheduling is carried out by a scheduler at a base station (e.g., an eNodeB) that receives allocation requests from user equipment (UEs) and assigns resource blocks in the shared channel to the UEs. The scheduler identifies high-interference resource blocks (RBs) in the shared communications channel. The scheduler assigns UEs to portions of the shared channel having high-interference RBs if the error rate expected to result from the assignment falls at or below an error rate threshold. If the expected error rate is greater than the error rate threshold, the scheduler assigns the UE to another portion of the shared channel.
