    摘要: A scheduler capable of operating in an Orthogonal Frequency Division Multiplexing communication system schedules a control channel for a user equipment by determining a channel quality metric associated with the user equipment, calculating a target control channel element quality metric, determining a control channel element utilization rate, wherein the control channel element utilization rate a past rate of utilization of control channel elements, and selecting a control channel element aggregation level for the control channel based on the channel quality metric, the target control channel element quality metric, and the control channel element utilization rate. The scheduler then allocates control channel elements to the control channel based on the selected control channel element aggregation level. The scheduler further may steal power from one or more unused control channel elements and assign the stolen power to control channel elements assigned to the control channel.
