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: Methods and apparatus are provided in which a configuration message to configure at least one uplink carrier is received. A power headroom report (PHR) is triggered for a first uplink carrier if a predetermined event occurs. An allocation of an uplink transmission resource is detected for the PHR. It is identified whether the first uplink carrier for which a power headroom (PH) is to be determined is different from a second carrier to which the uplink transmission resource is allocated. The PH is determined based on a first pathloss associated with the first uplink carrier, if the first uplink carrier is different from the second carrier. The PHR generated based the determined PH is transmitted.

Abstract: A method and apparatus for controlling measuring the frequency of a new cell within a forbidden registration area when a User Equipment (UE) enters into the new cell in a mobile communication system are provided. If the UE recognizes the new registration area as forbidden, the UE does not measure the frequency of the current cell for a predetermined reference time, and searches for a suitable cell for a normal service by measuring other frequencies. If no suitable cell in the other frequencies is found, the UE removes a measuring limitation and searches for an acceptable cell for a limited service by measuring frequencies including frequency of the current cell.

Abstract: A method and apparatus for initiating communications on a shared channel in a mobile communication system are provided. A user equipment transmits an uplink signal for requesting communications on the shared channel to a Node B, and waits for a delay duration without monitoring a downlink after transmitting the uplink signal. When the delay duration has elapsed, the user equipment monitors the downlink during a valid period and determines whether a downlink signal responding to the uplink signal is received in a transmission time interval within the valid period. When the downlink signal is received in the valid period, the user equipment transmits and receives data on the shared channel.
