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: A method for performing handover in a wireless communication system and a device therefor are disclosed. Specifically, the method for performing handover by a user equipment (UE) without a wireless local area network (WLAN) termination (WT) change from a source eNodeB (eNB) to a target eNodeB (eNB) in a wireless communication system, the method includes transmitting an end-marker request for requesting retransmission of an end-marker packet to the target eNB when a loss of the end-marker packet is detected after the handover without the WT change is started, and retransmitting the end-marker request or performing a recovery procedure for the end-marker packet when the end-marker packet is not received from the target eNB after the transmitting the end-marker request.

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: According to the present invention, a user equipment (UE) receives semi-persistent scheduling (SPS) resource configuration information relating to SPS resources and receives an SPS command indicating activation or deactivation of the SPS resources. The UE flushes, in response to the SPS command, a buffer of an HARQ process associated with an SPS resource to transmit an SPS confirmation medium access control (MAC) control element (CE). The UE transmits a new MAC protocol data unit (PDU) including the SPS confirmation MAC CE on the SPS resource by using the HARQ process.

Abstract: The present invention constructs L RLC PDUs, where L is larger than 1; and submit the L RLC PDUs to a medium access control (MAC) layer for a transmission opportunity. The L RLC PDUs include a first RLC PDU having a poll to trigger status reporting at a receiving device and a second RLC PDU not having the poll and having a highest sequence number (SN) among SNs of the L RLC PDUs. The present invention sets a state variable to a highest SN among SNs of RLC PDUs having the poll submitted to the MAC layer, upon submitting the first RLC PDU to the MAC layer.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting data in a wireless communication system. According to an aspect of the present invention, the method comprising: receiving, from an enhanced Node B (eNB), a grant with an indication that indicates at least one logical channel group (LCG) of which data should be transmitted using the received grant, wherein each of radio bearers (RBs) configured to the UE is associated with a respective logical channel priority; generating a medium access control protocol data unit (MAC PDU) including data of RBs belonging to the indicated at least one LCG; and transmitting the MAC PDU using the grant.

Abstract: A user equipment (UE) may be configured with multiple logical channels (LoCHs). The multiple LoCHs may include at least one LoCH (U-LoCH) allowed to be transmitted via a unlicensed band. If the UE receives a uplink grant for a licensed band, the UE disables a priority bit rate of the U-LoCH for the uplink grant when applying a logical channel prioritization procedure.

Abstract: A method for a user equipment (UE) operating in a wireless communication system including a first base station (BS) and a second BS. The UE includes two medium access control (MAC) entities: one MAC entity for the first BS and one MAC entity for the second BS. The method includes mapping a first logical channel group (LCG) including one or more logical channels for transmitting first data to the first BS to the one MAC entity for the first BS and a second LCG including one or more logical channels for transmitting second data to the second BS to the one MAC entity for the second BS; based on the first data belonging to a logical channel in the first LCG having a higher priority than priorities of other logical channels in the first LCG for which data is already available for transmission, triggering, by the one MAC entity for the first BS, a first buffer status report to the first BS independently of logical channels of the second LCG; and based on the second data belonging to a logical channel in the second LCG having a higher priority than priorities of other logical channels in the second LCG for which data is already available for transmission, triggering, by the one MAC entity for the second BS, a second buffer status report to the second BS independently of logical channels of the first LCG.
