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 group including a configured number (M) of beams; transmitting a random access preamble to a base station via the first beam group; adjusting a value of M when it is determined that the random access procedure has failed; and reselecting a second beam group including the adjusted number of M beams.

Abstract: A method and apparatus for supporting a random access channel (RACH)-less mobility with pre-allocated beams in a wireless communication system is provided. A user equipment (UE) receives a mobility command message which includes information on a pre-allocated UL resource for UL transmission with pre-allocated beams, synchronizes to a target cell, and performs the UL transmission to the target cell via the pre-allocated beams based on the pre-allocated UL resource for UL transmission to transmit a mobility complete message via a UL grant. If the UL transmission fails, the UE may perform RACH procedure.

Abstract: A method and apparatus monitoring preconfigured downlink resource (PDR) based on the uplink transmission in a wireless communication system is provided. A wireless device receives, from a network, uplink (UL) resource and configuration of preconfigured downlink (DL) resource related to the UL resource and. A wireless device determines whether to monitor the PDR based on usage of the UL resource and/or success of UL transmission via the UL resource.

Abstract: 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.

Abstract: Provided are a method for a user equipment (UE) to request system information in a wireless communication system and a device supporting the same. The method may include: transmitting a random access preamble for requesting system information to a base station (BS); receiving, from the BS, a random access response including only a random access preamble identifier (RAPID) corresponding to the transmitted random access preamble; and considering that a random access procedure is completed.

Abstract: Provided are a measurement reporting method of a terminal in which a primary cell is set and a terminal apparatus using the measurement reporting method. The method comprises: a step for adding a secondary cell; a step for determining whether the secondary cell is applicable to related measurement; and a step for determining whether the secondary cell is included in a cellsTriggeredList, wherein when the secondary cell is not applicable to the related measurement and the secondary cell is included in the cellsTriggeredList, the secondary cell is removed from the cellsTriggeredList.

Abstract: According to an embodiment of the present the UE can be scheduled to simultaneously receive one or more PDSCHs and one or more UE-group common PDSCHs at a same slot. When the simultaneously reception exceeds the UE's simultaneous reception capability, the UE may prioritizes a PDSCH for random access procedure over remaining PDSCHs, determine priorities of the remaining PDSCHs based on priority information in each DCI, and receive ‘M’ PDSCHs including the PDSCH for random access and ‘M−1’ PDSCHs selected from the remaining PDSCHs, where ‘M’ related to the UE's simultaneous reception capability.

Abstract: The present disclosure discloses a method of receiving a signal by a user equipment (UE) in a wireless communication system, including configuring a first transmission and reception point (TRP) using resources of a first cell, configuring a second TRP using resources of a second cell, receiving first downlink control information (DCI) scheduling a first physical uplink shared channel (PUSCH), receiving second DCI scheduling a second PUSCH, transmitting the first PUSCH to the first TRP, and transmitting the second PUSCH to the second TRP. The first DCI and the second DCI include information about a hybrid automatic repeat request (HARQ) process identifier (ID) and a transmission configuration indicator (TCI) state. The first cell is a cooperating cell, and the second cell is a serving cell.

Abstract: A user equipment (UE) receives a SPS resource configuration from an eNodeB (eNB), and transmits information related to a semi-persistent scheduling (SPS) activation for a specific logical channel to the eNB. The information may include timing information for the specific logical channel which indicates when a SPS resource for the specific logical channel should be activated. The specific logical channel may correspond to a vehicle-to-everything (V2X) communication.
