Abstract
A method and an apparatus for assigning data to split bearers in dual connectivity is provided. The apparatus includes a master evolved Node B (MeNB) of a user equipment (UE) configured to receive information of available buffer decided and transmitted by a secondary eNB (SeNB) through an X2 interface between the MeNB and the SeNB, determine whether the information is about available buffer for a UE or for an evolved radio access bearer (E-RAB) established on the SeNB based on an indicator in the information or a bearer that transported the information, and adjust the amount of data assigned to the SeNB according to the information of the available buffer. The apparatus can accommodate eNBs implemented in various manners, make full use of the bandwidth of data bearers, and reduce delay in data transmission.
