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: The method includes mapping a first logical channel group (LCG) including one or more logical channels for transmitting first data to the first base station (BS) to the one medium access control entity (MAC) 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; 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 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.

Abstract: A method for transmitting sidelink data by a User Equipment (UE) in a wireless communication system includes determining whether resource pool information for selecting a sidelink grant is configured by a base station; determining whether more sidelink data is available in a Sidelink Traffic Channel (STCH) than can be transmitted in a current Sidelink Control (SC) period; selecting resources for the sidelink grant from the resource pool information based on the resource pool information for selecting the sidelink grant being configured by the base station, and more sidelink data being available in the STCH than can be transmitted in the current SC period; selecting resources for the sidelink data based on the resources for the sidelink grant; and transmitting the sidelink data to another UE through the resources for the sidelink data. Further, the sidelink grant is for a next SC period after the current SC period.

Abstract: In a wireless communication system, a user equipment (UE) may reselect a sidelink resource to be used for vehicle-to-everything (V2X) communication. The reselection of sidelink resource may be triggered by various conditions. In particular, the reselection of the sidelink resources may be triggered when a value of sidelink resource reselection counter is zero. More specifically, the UE determines that data for the V2X communication is available in a sidelink traffic channel (STCH), determines that a value of the sidelink resource reselection counter is zero, and reselects the sidelink resources.

Abstract: A method for performing beam failure recovery (BFR) in a user equipment in a wireless communication system is disclosed. The method comprises performing a contention free random access procedure for BFR using a first beam during a BFR timer is running; and if the contention free random access procedure does not succeed until the BFR timer expires, performing a contention based random access procedure for BFR using a second beam selected from a beam set, wherein the first beam is excluded from the beam set.
