Abstract: The present invention relates to a resource allocation method of a vehicle-to-everything (V2X) transmission terminal in a wireless communication system and an apparatus therefor. More specifically, the method comprises the steps of: transmitting, to a V2X receiving terminal, a first V2X signal for a V2X service; receiving, from the V2X receiving terminal, an acknowledgment/negative-acknowledgment (ACK/NACK) for a V2X signal; and, if the NACK is received from the V2X receiving terminal, allocating, for a second V2X signal, a second time-frequency resource reserved in association with a first time-frequency resource for the first V2X signal.

Abstract: Provided are an operation method in accordance with uplink semi-persistent scheduling (SPS) of a terminal in a wireless communication system and a terminal using the method. The method is characterized by: receiving, from a base station, downlink control information (DCI) for indicating activation or release of uplink SPS; and decoding the DCI on the basis of a first radio network temporary identifier (RNTI) or a second RNTI. If the DCI is a first DCI for SPS for transmitting a signal to the base station, the DCI is decoded on the basis of the first RNTI, and, if the DCI is a second DCI for SPS for transmitting a vehicle-to-everything (V2X) signal, the DCI is decoded on the basis of the second RNTI. And the first RNTI and second RNTI are RNTIs that are different from each other.

Abstract: One embodiment of a modification of a semi-persistent scheduling (SPS) operation triggered by a terminal in a wireless communication system may be a single hybrid automatic repeat request (HARQ) process according to a plurality of SPS configurations. In other words, an eNodeB (eNB) can provide, to a UE, the plurality of SPS configurations covering a variety of message sizes. Another embodiment of a modification of an SPS operation triggered by a terminal may be a negative acknowledgement (NACK) with respect to a single HARQ process according to a plurality of SPS configurations and an SPS resource grant. In other words, an eNB provides, to a UE, the plurality of SPS configurations covering a dynamic reconfiguration of a message generation period, and whenever a specific SPS resource grant is not used for transmission, the terminal can transmit the NACK with respect to the SPS resource grant.

Abstract: A method for allowing a wireless resource to be allocated in a wireless communication system, and a device therefor are disclosed. Particularly, a method by which a terminal allows a wireless resource to be allocated in a wireless communication system can comprise the steps of: receiving, from a base station, one or more pieces of semi-persistent scheduling (SPS) configuration information comprising semi-persistent resource allocation information; receiving, from the base station, an SPS activation on specific SPS configuration information among the one or more pieces of SPS configuration information; allowing a specific SPS resource to be allocated on the basis of the specific SPS configuration information; and reporting, to the base station, information indicating a transmission state of the one or more pieces of SPS configuration information when a transmission of an SPS message using the specific SPS resource is stopped.
