    Abstract: The present invention relates to a method for transmitting an uplink (UL) data by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: transmitting the UL data to a first node based on a first Quality of Service (QoS) flow to data radio bearer (DRB) mapping rule; receiving, from the first node, a handover command including information related to a second QoS flow to DRB mapping rule; transmitting the UL data to the first node based on the first QoS flow to DRB mapping rule, until an UL data path is switched from the first node to the second node; and transmitting the UL data to the second node based on the second QoS flow to DRB mapping rule, after the UL data path is switched from the first node to the second node.

    Abstract: A method for a wireless device operating in a wireless communication system includes receiving configuration information for configuring a non-Physical Uplink Control Channel (PUCCH) cell; and transmitting a Hybrid Automatic Repeat request (HARQ) feedback of the non-PUCCH cell on a special cell (SpCell) or a PUCCH cell other than SpCell, according to indication information. Further, when the indication information is not received with the configuration information, the HARQ feedback is transmitted on the SpCell, and when the indication information is received with the configuration information, the HARQ feedback is transmitted on the PUCCH cell.

    Abstract: A method for a user equipment (UE) performing a random access to a network supporting NB-IoT (Narrow Band Internet of Things) is disclosed. The UE, operating on a first carrier, can move to a second carrier from the first carrier, and perform a random access procedure on the second carrier. The UE is configured to return to the first carrier, when the random access procedure on the second carrier is not successful, and when the random access procedure is a contention based random access procedure. Here, the first carrier is an anchor carrier if the UE is in RRC_IDLE state, and the first carrier is a configured carrier if the UE is in RRC_CONNECTED state.

    Abstract: The present invention relates to a method for processing signals by a node in a wireless communication system. In particular, the method includes receiving a radio bearer (RB) configuration message from a network; and configuring a radio bearer between a radio link control (RLC) entity of the node and a peer RLC entity using the RB configuration message, wherein the RB configuration message includes information about that the peer RLC entity operates with a different RLC mode from a RLC entity of the node.

    Abstract: A method and apparatus for combining UL data with a feedback of DL data in a wireless communication system is provided. A wireless device receives, from a network, information informing whether an application level uplink (UL) data, subsequent to a downlink (DL) data, is expected or not. A wireless device initiates random access procedure. A wireless device receives, from the network, the DL data in the random access procedure. A wireless device transmits a UL signaling including both the application level UL data and a feedback of the DL data based on the information informing that the application level UL data subsequent the DL data is expected.
