摘要： The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling pre-configured UL resources based on LBT procedure in wireless communication system, the method comprising: receiving information for UL resource configuration from a network, in a state that the UE is configured with at least one serving cell operating in an unlicensed spectrum; performing LBT operation for transmission of uplink data by using the UL resource, wherein the UE starts counting a number of failures of the LBT operation once the UE is not allowed to use the UL resource for transmission of uplink data during the LBT operation, and when the number of failures of the LBT operation reaches to the maximum number of LBT failure, stopping using the UL resource.

摘要： A method and apparatus for discarding data among associated transmission buffers in a wireless communication system is provided. A wireless device generates a first data packet and a second data packet, and performs a random access (RA) procedure based on the first data packet. When the RA procedure based on the first data packet fails, the wireless device discards the first data packet, and continues the RA procedure based on the second data packet. A media access control (MAC) layer indicates a radio resource control (RRC) layer that the RA procedure based on the second data packet is performed.

摘要： 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: upon transmitting the UL data based on a configured grant (CG) configuration related to a Hybrid-ARQ (HARQ) process, starting a first timer related to the HARQ process and a second timer related to the HARQ process; and performing retransmission of the UL data based on the HARQ process, wherein an UL resource on which the retransmission is performed is determined based on whether a UL resource of the CG configuration is configured or not between an expiration time point of the first timer and an expiration time point of the second timer.

摘要： In the present invention, the method, communication device or processing device determines an amount of uplink (UL) data available for a logical channel group (LCG); and transmit the buffer status report including information on the amount of UL data available for the LCG. In the present invention, the amount of UL data available for the LCG is selected based on all logical channels of the LCG except for a logical channel related to a suspended radio link control (RLC) entity among RLC entities configured for the communication or processing device.
