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: The present invention relates to a method of performing a random access (RA) procedure by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: triggering the RA procedure, wherein, when there is an ongoing scheduling request (SR) procedure on a first uplink (UL) bandwidth part (BWP), a second UL BWP is selected, wherein both an SR resource and PRACH resources are configured in the second ULBWP; and transmitting a RA preamble and a SR of the ongoing SR procedure on the second ULBWP.

Abstract: A method for a base station (BS) operating in a wireless communication system, the method includes transmitting, to a user equipment (UE), first information indicating a threshold value for an uplink data split operation; and receiving a buffer status report (BSR) from the UE, wherein a value of a buffer size in the BSR is determined based on second information that indicates an amount of data available for transmission for a packet data convergence protocol (PDCP) entity of the UE when the amount of the data available for transmission is larger than the threshold value.

Abstract: The present disclosure relates to a method for transmitting signals by a user equipment (UE) in a wireless communication system. In particular, the method includes configuring multiple logical channel groups; receiving an uplink grant with information about at least one of the multiple logical channel groups; and performing a buffer status report (BSR) triggering procedure for the at least one of the multiple logical channel groups based on the uplink grant.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling deactivation for a cell in which packet duplication is performed in wireless communication system, the method comprising: receiving a duplication activation command for a radio bearer; starting to perform a data duplication for the radio bearer according to the duplication activation command; and disabling a deactivation timer for a cell associated with the radio bearer when the duplication activation command is received.

Abstract: A user equipment (UE) starts a downlink (DL) discontinuous reception (DRX) retransmission timer for a DL hybrid automatic repeat and request (HARQ) process of the UE. The UE monitors a physical downlink control channel (PDCCH) while the DL DRX retransmission timer for the DL HARQ process is running. The UE stops the DL DRX retransmission timer for the DL HARQ process when the UE receives a PDCCH indicating a uplink (UL) transmission.

Abstract: In the present invention, a UE configured with a SPS resource which occurs periodically for a predetermined time duration transmits indication information using the last SPS resource which occurs last in the predetermined time duration, if the last SPS resource is not sufficient to accommodate uplink data available for transmission. The indication information informs a network that there is uplink data remaining after the UE performs uplink data transmission on the last SPS resource.

Abstract: The present invention relates to MAC layer communication for parallel random access procedures of dual connectivity. In this scheme, a first MAC entity of a user equipment informs the initiation of the first random access procedure to a second MAC entity of the UE; and informs the completion of the first random access procedure to the second MAC entity, when the first random access procedure is finished.

Abstract: A radio link control (RLC) entity can be used for multiple radio bearers (RBs). In other words, one RLC entity can be associated with multiple packet data convergence protocol (PDCP) entities, where the multiple PDCP entities are associated with the multiple RBs, respectively. An identifier of a PDCP or RB can be provided with a PDCP PDU in order to inform the RLC entity or a receiving device which RB or which PDCP entity the PDCP PDU is associated with. The RLC entity shared by more than one RB can be configured according to configuration information for RB(s).
