One objective of the present invention is to provide uplink scheduling information reporting apparatus and System supporting multi-connectivity. Herein, a UE connected to multiple eNBs, the UE receives trigger configuration information about buffer 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, when the BSR trigger condition of at least one of the multiple eNBs is satisfied, transmit to a corresponding eNB the buffer status report of the logical channel group that its corresponding radio bearer belongs to, so as to support uplink scheduling report in multi-connectivity. The reporting mechanism provides the serving eNB with information about data amount that can be transmitted in UL buffer of a UE, so as to support multi-connectivity, and enables macro cell to provide a better coverage of the control plane data and enables small cell to provide larger capacity. |
