Abstract: A method and apparatus for handling signaling delay for handover is provided. A wireless device transmits a measurement report based on a first event for a first cell, receives a handover command which commands a handover to the first cell, and checks validity of the handover command based on the first event for the first cell and/or a second event for a second cell other than the first cell.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for receiving handover assistance information including a list of one or more candidate target cells; initiating a first random access procedure to a first candidate target cell of the one or more candidate target cells and a first timer for the first candidate target cell, when the first candidate target cell satisfies a handover condition; and stopping trying to connect to the first candidate target cell when any one of at least the following events occurs: (i) the first timer expires for the first candidate target cell, and (ii) a number of random access trials to the first candidate target cell reaches a maximum number.

Abstract: Provided are a method of selecting BWP and a device supporting the method. According to one embodiment of the present invention, the method includes: configuring multiple bandwidth parts (BWPs) for a cell; activating a first BWP among the multiple BWPs; acquiring information on congestion of at least one of the multiple BWPs; and switching to a second BWP among the multiple BWPs from the first BWPs, based on the acquired information on congestion.

Abstract: A method and apparatus for triggering a transmission carrier reselection procedure for deactivated duplication in a wireless communication is provided. A wireless device selects a first carrier carrying a data unit, and selects a second carrier carrying a duplication of the data unit based on activation of the duplication of the data unit. The wireless device triggers a carrier reselection procedure based on deactivation of the duplication of the data unit.

Abstract: A method and apparatus for delayed Cell Group (CG) change procedure in a wireless communication system is provided. A wireless device triggers a measurement reporting based on a first event for a first cell, receives a cell group (CG) change command which commands CG change related to the first cell, and determines whether the CG change command is valid or not based on the first event for the first cell and/or a second event for a second cell other than the first cell.

Abstract: Provided are a method of access control and a device supporting the method. According to an embodiment of the present disclosure, the method includes: selecting access information for an access to a cell; determining channel access priority class (CAPC) mapped to the selected access information; performing a listen-before-talk (LBT) procedure based on the CAPC; and transmitting an access request to the cell, when a result of the LBT is successful. According to another embodiment of the present disclosure, the method includes: determining channel access priority class (CAPC) mapped to a control message; performing a listen-before-talk (LBT) procedure based on the CAPC; and transmitting the control message, when a result of the LBT is successful.

Abstract: A method and apparatus for random access procedure with an acknowledgement in wireless communication system is provided. A wireless device, in the wireless communication system, performs a first Random Access (RA) transmission to a network. The wireless device receives, from the network, a first Random Access Response (RAR) message in response to the first RA transmission. The wireless device attempts to decode the first RAR message. The wireless device transmits an acknowledgment (ACK) to the network based on that the first RAR message is successfully decoded. The wireless device performs a second RA transmission to the network based on that the first RAR message is not successfully decoded.

Abstract: A user equipment (UE) receives a grant on a semi-persistent scheduling (SPS) resource from an eNodeB (eNB). The UE determines that the SPS resource cannot accommodate an amount of data available for transmission for a specific logical channel. The UE transmits the SPS scheduling information for the specific logical channel to the eNB. The SPS scheduling information for the specific logical channel may be a scheduling request for the specific logical channel, and may be transmitted on an additional L1 control resource.

Abstract: Provided are a method for a user equipment (UE) to transmit a medium access control protocol data unit (MAC PDU) in a wireless communication system, and an apparatus supporting the same. The method may include: allocating resource grants on multiple carriers; selecting a first carrier among the multiple carriers, based on allocated time of the resource grants; allocating a resource of the selected first carrier to a logical channel with the highest priority; and transmitting the MAC PDU, by using the resource of the selected first carrier.
