Abstract: In the present invention, the transmitting device attaches a sequence number (SN) for each of service data unit (SDU) elements to generate a protocol data unit (PDU) containing the SDU elements. Each of the SDU elements is a SDU or SDU segment. The PDU includes the SDU elements and respective SNs for the SDU elements. The PDU includes an indicator for each of the SDU elements, and the indicator indicating whether a corresponding SDU element is a SDU or SDU segment.

Abstract: In the present invention, if a transmitting device receives an activation command for a packet duplication function of a PDCP entity for a radio bearer (RB), the PDCP entity submits a PDCP protocol data unit (PDU) to each of multiple lower layer entities associated with the PDCP entity, and each of the multiple lower layer entities transmits the PDCP PDU. If the transmitting device receives a deactivation command for the packet duplication function, the PDCP entity submits the PDCP PDU to a single one of the multiple lower layer entities, and the single one of the multiple lower layer entities transmits the PDCP PDU.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing an ACK/NACK indication based on the uplink grants over multiple subframes in a wireless communication system, the method comprising: starting a timer when an uplink grant is received from an eNB, wherein the uplink grant is valid while the timer is running; transmitting data using the uplink grant if the data is generated while the timer is running; monitoring an ACK indication or an or a NACK indication for the transmitted data on a subframe; checking whether the timer is running or not if the ACK indication for the transmitted data is not received on the subframe; and retransmitting the data using the uplink grant if the timer is running.
