Abstract: A method for transmitting data, performed by a transmitting apparatus in a wireless communication system, includes: transmitting a last acknowledged mode data (AMD) packet data unit (PDU) segment to a receiving apparatus, and activating a retransmission timer; identifying whether status report transmitted by the receiving apparatus is received until expiration of the retransmission timer; and when the status report is not received until the expiration of the retransmission timer, and a new AMD PDU and a retransmission-pending AMD PDU are not present in a data buffer, retransmitting the last AMD PDU segment to the receiving apparatus.

Abstract: There are provided a method for processing an exceptional case of establishing a default bearer and a device therefor in order to solve a problem in that a user equipment cannot actually receive an IP service by accessing a packet network while failing in establishing the default bearer in a mobile communication system. A method for processing an exceptional ease of establishing a default hearer in a mobility management entity includes: receiving a network attachment request from a user equipment; transmitting a network attachment acceptance including an activation request of the default bearer to the user equipment in response to the network attachment request; and cancelling a network attachment procedure when a completion response to the activation request of the default bearer is not received from the user equipment within a predetermined time.

Abstract: A discovery method is provided by a terminal in a terminal-to-terminal direct communication terminal-to-terminal direct communication. The terminal broadcasts a sequence, and receives an echo sequence on the sequence from other terminal. The terminal scrambles discovery information with the sequence, and transmits the scrambled discovery information.
