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.

Abstract: A method and apparatus for sidelink resource allocation and media access control (MAC) reset is provided. A wireless device, which is configured with network scheduled resource allocation for sidelink, sets new data indicators (NDIs) for all hybrid automatic repeat request (HARQ) process identifiers (IDs) specific to the sidelink to value 0, based on a media access control (MAC) reset being requested by an upper layer of the wireless device.

Abstract: A method for performing wireless communication by a first device and an apparatus for supporting same are provided. The method may comprise: receiving, from a base station, information related to a first sidelink (SL) resource and information related to a first physical uplink control channel (PUCCH) resource; transmitting, to a second device, a medium access control (MAC) packet data unit (PDU) by using the first SL resource, wherein the MAC PDU includes a packet related to a logical channel for which hybrid automatic repeat request (HARQ) feedback is disabled, and wherein the MAC PDU includes no packet related to a logical channel for which HARQ feedback is enabled; determining that retransmission of the MAC PDU is required; and transmitting, to the base station, NACK information by using the first PUCCH resource based on no SL grant available for retransmission of the MAC PDU.

Abstract: A terminal according to one embodiment of the present invention may: receive first DCI including a first HARQ process ID field and a first NDI field on the basis of a first RNTI for a terminal group; receive a first PDSCH scheduled by the first DCI; receive second DCI on the basis of a second RNTI dedicated to the terminal in a state in which a data block of the first PDSCH has not been successfully decoded; and receive a second PDSCH scheduled by the second DCI, wherein a second HARQ process ID field included in the second DCI indicates the same HARQ process as the first HARQ process ID field included in the first DCI; and, on the basis of the fact that a value of a second NDI field included in the second DCI is the same as the value of the first NDI field included in the first DCI, a data block of the second PDSCH may be decoded on the assumption that the second PDSCH includes retransmission for the data block of the first PDSCH that has not been successfully decoded, notwithstanding that the second RNTI is different from the first RNTI.

Abstract: A method and apparatus for clearing retransmission resources based on acknowledgement in a wireless communication system is provided. A first wireless device reserves multiple sets of resources for transmissions of multiple media access control (MAC) protocol data units (PDUs), transmits a first MAC PDU to a second wireless device using at least one resource from a first set of resources corresponding to the first MAC PDU among the multiple sets of resources, receives a positive acknowledgement for the first MAC PDU from the second wireless device, and clears remaining resources from the first set of resources corresponding to the first MAC PDU.

Abstract: The present invention is directed to a method and an apparatus for use in a wireless communication system. Specifically, the present invention is directed to a method comprising: receiving essential System Information (SI) from a first cell, the essential SI including information for acquiring an on-demand SI; requesting the on-demand SI to the first cell; if the on-demand SI is not received from the first cell in a first specific period of time after the requesting the on-demand SI to the first cell is successful, re-requesting the on-demand SI to the first cell; and if the on-demand SI is not received from the first cell in a second specific period of time after a total number of requesting the on-demand SI to the first cell reaches a maximum value, re-selecting a second cell under assumption that the first cell is a barred cell, and an apparatus therefore.

Abstract: According to at least one of embodiments of the present disclosure, a UE may receive paging early indication (PEI)-related information through higher-layer signaling, attempt to detect a PEI associated with ‘M’ paging occasions (POs) based on the PEI-related information, determine whether to perform or skip monitoring of a physical downlink control channel (PDCCH) in a specific PO related to the UE among the plurality of POs, based on the detected PEI, and receive at least one of paging downlink control information (DCI) carried by the PDCCH or a physical downlink shared channel (PDSCH) scheduled by the paging DCI, in a state in which the UE determines to perform monitoring of the PDCCH.
