Abstract: In one embodiment, a method for performing an operation for a first terminal in a wireless communication system comprises the steps of: determining that a physical layer problem has occurred during communication with a base station; switching from resource allocation mode 1 to resource allocation mode 2 on the basis of the physical layer problem; and transmitting, in resource allocation mode 2, sidelink data to a second terminal by using a sidelink resource, wherein the sidelink resource is determined as a sensing-based resource and/or a random selection-based resource in consideration of the latency budget and sensing validity period of the sidelink data.

Abstract: The present disclosure relates to channel state reporting in wireless communications. According to an embodiment of the present disclosure, a method performed by a first wireless device in a wireless communication system comprises: establishing a PC5 radio resource control (RRC) connection between the first wireless device and a second wireless device; receiving sidelink control information (SCI) from the second wireless device, wherein the SCI instructs the first wireless device to perform sidelink (SL)-channel state information (CSI) reporting for the PC5 RRC connection; triggering the SL-CSI reporting; and based on that a sidelink resource for the SL-CSI reporting is unavailable and the first wireless device is configured with a mode in which sidelink resources are scheduled by a network, transmitting a signal related to the SL CSI reporting for requesting the sidelink resource to the network.

Abstract: A method and apparatus for trigger and/or cancellation of sidelink scheduling request (SR) in a wireless communication system is provided. A wireless device determines that a physical uplink control channel (PUCCH) resource for transmission of a scheduling request (SR) overlaps with a sidelink (SL) resource for transmission of a SL media access control (MAC) protocol data unit (PDU). The wireless device transmits, to a network, the SR by using the PUCCH resource when a priority of the SR is higher than a priority of the SL MAC PDU.

Abstract: One embodiment of the present disclosure provides a method for a first device to transmit SL HARQ feedback information. The method comprises the steps of: receiving a PSSCH from a second device; determining a resource related to a PSFCH on the basis of a resource related to the PSSCH; determining an SL HARQ feedback option on the basis of link quality between the first device and the second device; and transmitting SL HARQ feedback information on the PSSCH to the second device through the resource related to the PSFCH, on the basis of whether or not decoding for a transmission block received through the PSSCH is successful and the SL HARQ feedback option, wherein the SL HARQ feedback option is determined as any one from among a first SL HARQ feedback option and a second SL HARQ feedback option.
