A method for a mobile terminal comprising the steps of: receiving by the mobile terminal a semi-persistent scheduling configuration via RRC signaling from a base station; triggering and generating by the mobile terminal a buffer status report, BSR, taking into account a scheduling mode being one of a semi-persistent or dynamic scheduling mode of a first or second radio bearer and a scheduling mode status of the respective first or second radio bearer to decide whether data of the respective first or second radio bearer is to be considered in the BSR; whereby in the dynamic scheduling mode radio resource are dynamically allocated by dynamic grants, and in the semi-persistent scheduling mode radio resources are allocated on a semi-persistent basis by semi-persistently configured scheduling grants; and whereby taking into account the scheduling mode status comprises taking into account the activation status of a presently configured semi-persistent resource allocation, and taking into account whether or not a respective semi-persistently scheduled radio bearer is considered in the activated semi-persistent resource allocation; transmitting by the mobile terminal a scheduling request to the base station in case there are no uplink resources allocated to the mobile terminal for the current transmission time interval and a BSR was triggered for the second radio bearer being a semi-persistently scheduled radio bearer which is not considered in the activated semi-persistent resource allocation; transmitting by the mobile terminal the triggered and generated BSR with the data of the second radio bearer, if there is data of the second radio bearer to be considered in the BSR, using radio resources which are dynamically allocated to the mobile terminal by a dynamic grant which was received on a Physical Downlink Control Channel, PDCCH, in response to the scheduling request; and not transmitting by the mobile terminal another scheduling request to the base station in case no BSR was triggered for the first, second, or another radio bearer, on the arrival of new data for the first radio bearer being a semi-persistently scheduled radio bearer and which is already considered in the activated semi-persistent resource allocation. receiving by the mobile terminal a semi-persistent scheduling configuration via RRC signaling from a base station; triggering and generating by the mobile terminal a buffer status report, BSR, taking into account a scheduling mode being one of a semi-persistent or dynamic scheduling mode of a first or second radio bearer and a scheduling mode status of the respective first or second radio bearer to decide whether data of the respective first or second radio bearer is to be considered in the BSR; whereby in the dynamic scheduling mode radio resource are dynamically allocated by dynamic grants, and in the semi-persistent scheduling mode radio resources are allocated on a semi-persistent basis by semi-persistently configured scheduling grants; and whereby taking into account the scheduling mode status comprises taking into account the activation status of a presently configured semi-persistent resource allocation, and taking into account whether or not a respective semi-persistently scheduled radio bearer is considered in the activated semi-persistent resource allocation; transmitting by the mobile terminal a scheduling request to the base station in case there are no uplink resources allocated to the mobile terminal for the current transmission time interval and a BSR was triggered for the second radio bearer being a semi-persistently scheduled radio bearer which is not considered in the activated semi-persistent resource allocation; transmitting by the mobile terminal the triggered and generated BSR with the data of the second radio bearer, if there is data of the second radio bearer to be considered in the BSR, using radio resources which are dynamically allocated to the mobile terminal by a dynamic grant which was received on a Physical Downlink Control Channel, PDCCH, in response to the scheduling request; and not transmitting by the mobile terminal another scheduling request to the base station in case no BSR was triggered for the first, second, or another radio bearer, on the arrival of new data for the first radio bearer being a semi-persistently scheduled radio bearer and which is already considered in the activated semi-persistent resource allocation.
