Claim:
Method in a base station for allocating scheduling request resources to a user equipment served by the base station, the base station and the user equipment are comprised within a wireless communication system, the method comprising the steps of: receiving a bearer setup message from the user equipment, sending, to the user equipment, a first instruction identifying a first scheduling request interval, to be used by the user equipment, wherein the scheduling request interval defines a period of time between adjacent scheduling request resources, and the scheduling request resource identifies moments in time allocated to the user equipment for sending a scheduling request to the base station; receiving a scheduling request from the user equipment, based on the first scheduling request interval; estimating the moment of time when data was generated at the user equipment, based on the received scheduling request, estimating a periodicity of data generation at the user equipment, determining a second scheduling request interval to be used by the user equipment, based on the estimated periodicity of data generation at the user equipment, determining a scheduling request resource to be allocated to the user equipment, based on the estimated moment of time when data was generated at the user equipment, and sending, to the user equipment, a second instruction comprising the determined second scheduling request interval and scheduling request resource, in order to adjust the scheduling request resources of the user equipment.
