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: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for selecting prose destinations or SL grants in a D2D communication system, the method comprising: receiving or selecting N numbers of SL grants used for a next SC period; selecting ProSe destinations in decreasing order of priority of ProSe destination so that selected numbers of ProSe destinations are equal to N, wherein a priority of ProSe destination is set to priority of a SL logical channel with a highest priority among all SL logical channels associated with the ProSe destination; and transmitting SL data of the selected ProSe destinations using the N numbers of SL grants in the next SC period, wherein SL data of each of the selected ProSe destinations is transmitted using a corresponding SL grant among the N numbers of SL grants.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing reflective Quality of Service (QoS) in wireless communication system, the method comprising: receiving a DL PDU with a QoS flow ID via a DL DRB identified by a first DRB ID from a network; determining whether or not to update UL QoS flow to DRB mapping rule according to a value of the QoS flow ID; and transmitting UL data via a UL DRB mapped to QoS flow ID of the UL data based on the UL QoS flow to DRB mapping rule, wherein if the QoS flow ID is not a specific value but a first QoS flow ID, the UL QoS flow to DRB mapping rule is updated such that a UL DRB mapped to the first QoS flow ID is changed to a UL DRB identified by the first DRB ID, and wherein if the QoS flow ID is the specific value, the UE doesn't update the UL QoS flow to DRB mapping rule.

Abstract: A method and apparatus for configuring a cell in a wireless communication system is provided. A user equipment (UE) receives a radio resource control (RRC) message which includes a configuration for a secondary cell (SCell) and an indication of an initial state of the SCell. The initial state of the SCell is set to either one of an activated state and deactivated state. The UE configures the SCell based on the configuration and the initial state of the SCell.

Abstract: A method and a device for contention resolution in a random access procedure in a D2D communication system are discussed. The method includes transmitting a message containing a buffer status information for data transmission over PC5 interface in a random access procedure; receiving a Physical Downlink Control Channel (PDCCH) in response to the message; and considering contention resolution successful if the received PDCCH is addressed to sidelink-RNTI (SL-RNTI).

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for operating fast random access procedure in a wireless communication system, the method comprising: starting a Random Access Response (RAR) reception procedure by transmitting a Random Access Preamble (RAP) to an e-NodeB (eNB); receiving, from the eNB, an indicator indicating that the UE check a condition for whether the UE stops the RAR reception procedure or not, checking whether the condition is met or not; and stopping RAR reception procedure if the condition is met.

Abstract: A user equipment (UE) starts a downlink (DL) discontinuous reception (DRX) retransmission timer for a DL hybrid automatic repeat and request (HARQ) process of the UE. The UE monitors a physical downlink control channel (PDCCH) while the DL DRX retransmission timer for the DL HARQ process is running. The UE stops the DL DRX retransmission timer for the DL HARQ process when the UE receives a PDCCH indicating a uplink (UL) transmission.
