Abstract
The invention relates to a method for requesting uplink resources by a user equipment in a communication system, wherein a DRX, Discontinued Reception, function is running at the user equipment. The transmission of a scheduling request for requesting uplink resources to a radio base station is triggered upon triggering of a buffer status report in the user equipment. However, the triggering of the scheduling request is delayed such that the scheduling request is triggered in one of the subframes—preferably the first subframe—of an On-Duration period of a DRX cycle according to the DRX function. Correspondingly, the triggered scheduling request is transmitted to the radio base station in the next possible scheduling request transmission occasion after the triggering of the scheduling request is delayed.
