Abstract: Method and apparatus for a user equipment (UE) performing random access are disclosed. For this end, the UE transmits first multiple random access preambles for a random access procedure to the network, and monitors random access responses respectively corresponding to each of the first multiple random access preambles during each of multiple random access response reception windows. The UE transmits second multiple random access preambles for the random access procedure to the network, if a random access response reception of the first multiple random access preambles is determined as not successful. Here, the random access response reception is determined as not successful, when none of the random access responses is successfully received until a last random access response reception window among the multiple random access response reception windows ends.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting a power headroom reporting in wireless communication system, the method comprising: calculating multiple Power Headroom (PH) values per an active cell; selecting one PH value among the multiple PH values for setting a value of a PH field of a corresponding cell to the selected PH value; generating a Power Headroom Reporting (PHR) Medium Access Control (MAC) Control Element (CE) including the PH field set to the selected PH value; and transmitting a MAC Protocol Data Unit (PDU) including the generated PHR MAC CE to a network.

Abstract: A method for performing an uplink (UL) transmission by user equipment (UE) in a wireless communication system is disclosed. The method comprises steps of receiving an UL grant from a gNB; selecting a Hybrid Automatic Repeat Request (HARQ) process among available HARQ processes; generating a data unit to be transmitted on the UL grant; and transmitting the data unit using the selected HARQ process with information related to the selected HARQ process.

Abstract: The present invention relates to a method for transmitting a signal by a user equipment in a wireless communication system. In particular, the method includes the steps of: receiving a discard indication for a data unit from an upper layer; discarding the data unit in a buffer; if the buffer becomes empty upon discarding the data unit, selecting a specific data unit among data units received from the upper layer before a reception of the discard indication; including a status report request indicator into the specific data unit; and transmitting the specific data unit to a network.

Abstract: A method for tr transmitting data by a node in a wireless communication system is disclosed. The method comprises transmitting the data related to the first set of bearers to a first node and transmitting the data related to the second set of bearers to a second node; based on a radio link problem related to the first node occurring, selecting at least one bearer among the first set of bearers based on a preconfigured criterion; and transmitting the data related to the selected at least one bearer to the second node.

Abstract: The present invention relates to a method of transmitting uplink (UL) data by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: based on the UE transmitting the UL data on a UL resource of a configured grant (CG) configuration based on a Hybrid-ARQ (HARQ) process, starting a CG timer for the HARQ process; based on retransmission of the UL data based on the HARQ process not being performed until expiration of the CG timer, determining that a transmission of the UL data is not successful; and performing retransmission of the UL data based on the HARQ process after the expiration of the CG timer.

Abstract: A method for monitoring a physical downlink control channel (PDCCH) with a discontinuous reception (DRX) related timer by a user equipment (UE) configured not to transmit a Hybrid Automatic Repeat and request (HARQ) feedback for the DL HARQ process in a wireless communication system is disclosed. Especially, when the UE processes the data block, a timer for monitoring subsequent PDCCHs related to retransmission of the DL HARQ process is started without transmitting the HARQ feedback upon a first Physical downlink Control Channel (PDCCH) for the DL HARQ process is detected. Then, while the timer is running, the UE monitors subsequent PDCCHs related to retransmission of the DL HARQ process. Further, when decoding of DL data related to the second PDCCH successes, the timer is stopped and monitoring subsequent PDCCHs for the DL HARQ process is skipped.

Abstract: A user equipment (UE) can perform dual registration with different radio access technology (RAT) system. The UE registers with a core network of a second system independent of a first system while maintaining registration with a core network of the first system. The UE transmits, to the second system, first information indicating that the UE has the registration with the first system when connecting to the second system. One of the first and second systems may be a LTE system using a first radio access technology (RAT), and the other one may be new RAT system using a second RAT different from the first RAT.
