Abstract: A data transmission method of a User Equipment, UE, in a Long Term Evolution, LTE, compliant mobile communications network, and a corresponding UE. The method comprises detecting reconfiguration of a bearer from a split bearer in which uplink Packet Data Convergence Protocol, PDCP, Protocol Data Units, PDUs, are transmitted to both a Master eNB, MeNB, and to a Secondary eNB, SeNB, to a non-split bearer in which uplink PDCP PDUs are transmitted only to the MeNB. If reconfiguration of a bearer from a split bearer to a non-split bearer in which uplink PDCP PDUs are transmitted to the MeNB is detected, the method further comprises initiating retransmission of PDCP PDUs from the first PDCP PDU for which transmission was attempted via the SeNB and for which there has been no confirmation of successful delivery by a protocol layer below the PDCP layer within the UE. The method further comprises retransmitting only PDCP PDUs for which transmission of the PDU was attempted via the SeNB.

Abstract: The present invention relates to a method and an apparatus for performing operations of an eNB and a UE to effectively use a minimization of drive test (MDT) technology in a mobile communication system. The present invention provides a method for transmitting/receiving MDT measurement information of an eNB in a mobile communication system, the method comprising the steps of: configuring an MDT in a UE; collecting MDT measurement information from the UE; determining whether enhanced inter-cell interference coordination (eICIC) is configured in the UE in which the MDT is configured, and, when the eICIC is configured in the UE, reporting indication information indicating that the MDT measurement information is affected by the eICIC together with the MDT measurement information.
