Method Between Two eNBs to Agree on Radio Resource Configuration for a UE Which Supports Dual Connectivity Between the eNBs

摘要

A UE, a SeNB and a MeNB are provided as well as respective method performed thereby for modifying a radio resource configuration of the SeNB with respect to the UE, currently being connected to the MeNB, wherein the UE, the SeNB and the MeNB are operable in a wireless communication system, the wireless communication system being adapted to provide for dual connectivity between the UE and the MeNB, and between the UE and the SeNB. The method performed by the UE comprises receiving (2310), from the MeNB, a SeNB configuration for the radio resource of the SeNB with respects to the UE; and sending (2320) a confirmation to the SeNB, confirming the received SeNB configuration. The method further comprises applying (2340) the received SeNB configuration for the radio resource configuration of the SeNB.
