    Abstract: Improving communication efficiency in handover re-establishing an ARQ entity in a mobile communication system is disclosed. The method includes transmitting first Packet Data Convergence Protocol (PDCP) Packet Data Units (PDUs) correctly received from the source cell, together with a special indication requiring reordering of the first PDCP PDUs, from a Radio Link Control (RLC) receiving buffer to a PDCP receiving entity when a handover command message from a source cell to a target cell is received; buffering the first PDCP PDUs in a PDCP PDU reordering buffer by the PDCP receiving entity in response to the special indication; and when a second PDCP PDU is received from the target cell through a new RLC receiving entity for the target cell, outputting third PDCP PDUs up to a PDCP PDU before a first missing PDCP PDU having a sequence number higher than that of the second PDCP PDU from the PDCP reordering buffer. In the method, a PDCP entity performs reordering, thereby improving efficiency of communication.

    Abstract: A method and apparatus for connecting to a secondary enhanced NodeB. A transceiver configured to receive a Radio Resource Control (RRC) message from a Master enhanced NodeB (MeNB). The RRC message comprises a dedicated random access resources configuration for the UE to perform random access to a cell associated with a Secondary enhanced NodeB (SeNB) for a purpose of an addition of the SeNB, and an identification of the cell to which the random access is to be performed. Responsive to receiving the RRC message, command the Media Access Control (MAC) to trigger the random access for the addition of the SeNB to the cell with the identification indicated in the RRC message with the random access resources indicated in the RRC message. The MeNB is an eNB which the UE connects to initially and which acts as mobility anchor.
