Abstract: Provided are a method for a terminal transmitting an uplink on the basis of an uplink feedback indicator in a wireless communication system, and a device supporting same. The method may comprise the steps of: receiving, from a base station, an uplink feedback indicator indicating whether uplink feedback for a paging indicator is enabled; receiving, from the base station, a paging indicator corresponding to the ID of the terminal; and transmitting an uplink as a response to the paging indicator if the uplink feedback indicator indicates that uplink feedback for the paging indicator is enabled.

Abstract: An in-vehicle terminal engaged in vehicle-to-everything (V2X) communication, especially vehicle-to-vehicle (V2V) communication, establishes a reporting cycle on the basis of the speed of the in-vehicle terminal, and transmits geographic information of the in-vehicle terminal to a network cyclically on the basis of the reporting cycle. That is, the reporting cycle may be shortened as the in-vehicle terminal speed increases, or may be lengthened as the in-vehicle terminal speed decreases.

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: 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: A method and apparatus for flushing a hybrid automatic repeat request (HARQ) buffer in a wireless communication system is provided. A user equipment (UE) receives information on multiple resource pools from a network, selects a first resource pool among the multiple resource pools, and stores a media access control (MAC) protocol data unit (PDU) in the HARQ buffer for transmission via the first resource pool. When the UE reselects a second resource pool among the multiple resource pools, the UE flushes the HARQ buffer.

Abstract: A method for processing signals by a user equipment (UE) in a Wireless communication system is disclosed. The method includes steps of transmitting, to a network, a request message for configuring a time resource in which a transmission of a message via a sidelink is prioritized over a transmission of an uplink message and a reception of a downlink message; receiving, from the network, a configuration message as a response of the request message; and transmitting the V2X message in the time resource via the sidelink.
