A MASTER AND SECOND EVOLVED NODE B AND METHOD PERFORMED THEREBY FOR MODIFYING A RADIO RESOURCE OF THE SENB WITH RESPECT TO A UE CURRENTLY BEING CONNECTED TO THE MENB

摘要

A MeNB and a SeNB and respective methods performed thereby for modifying a radio resource of the SeNB with respect to a UE currently being connected to the MeNB are provided.The MeNB and SeNB 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 the UE and the SeNB. By modifying means changing an existing radio resource configuration or adding a RAB between the SeNB and the UE. The method comprisestransmitting (2310), to the SeNB, a request for radio resource modification with regards to an SeNB radio resource configuration between the SeNB and the UE, the request comprising a target MeNB radio resource configuration; and receiving (2320), from the SeNB, the SeNB radio resource configuration with regards to the radio resource between the SeNB and the UE.
