An uplink scheduling information reporting apparatus supporting multi-connectivity at a UE, wherein the UE is connected to multiple eNBs (20, 30), the apparatus characterized by: a configuration receiving module configured to receive trigger configuration information about butter status report of a logical channel group that a corresponding radio bearer belongs to, and radio bearer configuration information and uplink resource configuration information respectively corresponding to each of the multiple eNBs, wherein the trigger configuration information is available for the UE to configure BSR trigger condition corresponding to each of the multiple eNBs; a BSR report module configured to, when the BSR trigger condition of at least one of the multiple eNBs is satisfied, transmit to a corresponding eNB the butter status report of the logical channel group that its corresponding radio bearer belongs to; wherein the radio bearer includes data radio bearer, which data radio bearer is transmitted through at least two of the multiple eNBs (20, 30), which at least two eNBs for transmitting become transmitting eNBs, in which one transmitting eNB is a macro eNB, and other transmitting eNB(s) is a small cell eNB, whose corresponding small cell is located within a macro cell provided by the macro eNB, the BSR reporting module is further configured to: - when the BSR trigger condition of the macro eNB is satisfied, transmit the buffer status report of the logical channel group to which the data radio bearer belongs to the macro eNB, such that the macro eNB determines respective amounts of data to be transmitted through itself and the other transmitting eNB(s), respectively, and further the buffer status report and decision information corresponding to the amounts of data is provided by the macro eNB to the corresponding other transmitting eNB(s), or - when the BSR trigger conditions of the transmitting eNB are satisfied, transmit the buffer status report of the logical channel group to which the data radio bearer belongs to each of the transmitting eNBs, such that the macro eNB determines respective amounts of data to be transmitted through itself and the other transmitting eNB(s), and further the macro eNB provides decision information corresponding to the amounts of data to corresponding other transmitting eNB(s). a configuration receiving module configured to receive trigger configuration information about butter status report of a logical channel group that a corresponding radio bearer belongs to, and radio bearer configuration information and uplink resource configuration information respectively corresponding to each of the multiple eNBs, wherein the trigger configuration information is available for the UE to configure BSR trigger condition corresponding to each of the multiple eNBs; a BSR report module configured to, when the BSR trigger condition of at least one of the multiple eNBs is satisfied, transmit to a corresponding eNB the butter status report of the logical channel group that its corresponding radio bearer belongs to;
