Abstract: A method and apparatus for selecting a sidelink resource for a sidelink CSI reporting in a wireless communication system is provided. A first wireless device triggers the SL CSI reporting for the PC5-RRC connection. A first wireless device determines to create a sidelink grant corresponding to transmission of a single MAC PDU based on the triggered SL CSI reporting or a SL data available for transmission. A first wireless device triggers a resource selection procedure based on the determination. A first wireless device selects a sidelink resource in the resource selection procedure.

Abstract: An embodiment relates to a method for transmitting and receiving a sidelink signal for a first terminal in a wireless communication system, the method comprising the steps of: receiving, from a base station, a signal for allocating one or more first resources; transmitting the sidelink signal to a second terminal by using the one or more first resources; receiving, from the second terminal, a hybrid automatic repeat request (HARQ) non-acknowledgement (NACK) signal, in response to the sidelink signal; and retransmitting the sidelink signal to the second terminal by using a second resource, wherein the second resource is selected from a preset source pool on the basis of the absence of a resource for the retransmission of the sidelink signal.

Abstract: In a wireless communication system, a third party different from both terminals or a base station, which are parties to vehicle-to-everything (V2X) communication, may be involved in resource allocation for the V2X communication. For example, a first terminal performing V2X communication with a second terminal receives recommendation information recommending a resource available for the V2X communication from a third terminal and performs the V2X communication with the second terminal by using a recommended resource determined based on the recommendation information or a resource selected by the first terminal based on the recommendation information.

Abstract: A method and apparatus for data transmission considering feedback and sidelink resource allocation in a wireless communication system is provided. A wireless device enables a hybrid automatic repeat request (HARQ) feedback for a logical channel, selects to create a sidelink grant corresponding to transmissions of a single media access control (MAC) protocol data unit (PDU) or multiple MAC PDUs, and performs transmission resource reselection check. When there is no sidelink grant for which the HARQ feedback is enabled on a carrier, the wireless device triggers TX resource selection on the carrier.

Abstract: Provided are a method for performing sidelink transmission by a first device (100) in a wireless communication system, and a device for supporting same. The method comprises the steps of: determining a transport block size (TBS) on the basis of whether at least one of an automatic gain control (AGC) symbol and a guard period (GP) symbol is used for sidelink transmission; and performing the sidelink transmission with respect to a second device (200) on the basis of the determined TBS, wherein the AGC symbol may be a symbol which a first device (100) uses for AGC, and the GP symbol may be a symbol which the first device (100) uses for TX/RX switching.

Abstract: Provided is a method of operating a transmitting user equipment (UE) in a wireless communication system. The method includes receiving a first radio resource control (RRC) configuration-related message by the transmitting UE (Tx UE), and transmitting a message to a receiving UE by the Tx UE. The first RRC configuration-related message includes sidelink hybrid automatic repeat request (HARQ) enable or HARQ disable configuration information.
