Abstract: Methods and apparatuses are provided in a wireless communication system supporting dual connectivity of a first base station and a second base station. A predetermined number of consecutive out-of-syncs for a special cell are received. A timer for the special cell is started. A radio link failure (RLF) is detected upon an expiration of the timer. A failure message including failure type is transmitted to the first base station in case that the RLF for the special cell is associated with the second base station.

Abstract: Methods and apparatuses are provided for performing multi-eNB connectivity communication. An eNB receives a Radio Link Failure (RLF) expected message related to a first link, from a UE. A target cell is sought for a handover of the UE according to the RLF expected message. The target cell is selected, when the target cell is found. The eNB receives, from the UE, an RLF message related to the first link, through a second link. An instruction for the handover to the selected target cell is transmitted to the UE.
