The present invention relates to a method for detecting loss in DRX synchronization in a telecommunications system. The present invention further relates to a base station configured to perform the method for detecting the loss in DRX synchronization. The method comprises the steps of assigning radio resources to a UE for enabling the UE to send uplink information to the base station. The method further comprises the step of detecting loss in DRX synchronization when information that is expected by the base station is absent on the assigned resource(s).
