Abstract: A method for performing a Discontinuous Reception (DRX) operation by a connected mode User Equipment (UE) in a mobile communication system. The method includes waking up at a wake-up timing, and determining whether an incoming data indication is received from a Node B; reestablishing uplink synchronization upon receipt of the incoming data indication; and waking up after sleeping for a time from the incoming data indication reception timing, receiving a transmission resource allocation message from the Node B, and receiving downlink data over allocated transmission resources.

Abstract: A method and apparatus are provided for transmitting power headroom information by a terminal in a mobile communication system. The method includes obtaining, by the terminal, an uplink transmission resource; obtaining, by the terminal, a path loss; and if the path loss is changed more than a threshold since a last transmission of a power headroom, obtaining power headroom information using a maximum transmission output of the terminal and a transmission power of the terminal, and transmitting the power headroom information using the uplink transmission resource.

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.
