Abstract: Provided is a method for performing a random access procedure by a terminal in a wireless communication system. The method comprises the steps of: selecting a first beam having a quality equal to or higher than a preconfigured threshold value; transmitting a random access preamble to a base station via the first beam; adjusting the threshold value when it is determined that the random access procedure has failed; and reselecting a second beam having a quality equal to or higher than the adjusted threshold value.

Abstract: Method and apparatus for a user equipment (UE) transmitting uplink signals in a wireless communication system are disclosed. For this end, the UE, receiving first uplink grant information and logical channel priority information associated with the first uplink grant, constructs a first data unit including data from one or more radio bearers with first logical channel priority corresponding to the logical channel priority information. And, the UE transmits the first data unit to a network.

Abstract: 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.

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: In the present invention, a user equipment (UE) receives resource configuration information including information on a first radio resource not dedicated to the UE. The UE performs transmission of uplink data using the first radio resource. The UE transmits a request for radio resource dedicated to the UE for retransmission of the uplink data if the transmission of the uplink data using the first radio resource is not successful for a certain number of transmissions of the uplink data or for a certain period of time.
