Abstract: A method and apparatus for hybrid automatic repeat request (HARQ) transmissions for configured grants (CGs) in a wireless communication system is provided. A first wireless device receives a retransmission resource for a HARQ process identifier (ID) for a CG. When a number of transmissions of a media access control (MAC) protocol data unit (PDU) does not reach to a maximum number of transmissions, the first wireless device performs retransmission of the MAC PDU to a second wireless device by using the retransmission resource. When the number of transmissions of the MAC PDU reaches to the maximum number of transmissions, the first wireless device flushes a HARQ buffer in a sidelink process.

Abstract: A first device performs wireless communication by performing operations that include: attaching cyclic redundancy check (CRC) bits to first bits related to second sidelink control information (SCI), thereby acquiring second bits; acquiring third bits based on channel coding regarding the second bits; acquiring the number of first modulation symbols related to the second SCI acquiring the number of second modulation symbols related to the second SCI by adding a gamma value to the number of the first modulation symbols based on the number of at least one resource element (RE), to which the first modulation symbols are not mapped, among multiple REs on a symbol, to which the last modulation symbol among the first modulation symbols is mapped, within a resource block (RB) to which the last modulation symbol belongs; and performing rate matching regarding the third bits based on the second modulation symbols.

Abstract: According to an embodiment of the present disclosure, a method for performing sidelink communication is provided. The method may include: receiving sidelink control information (SCI) from a second apparatus and transmitting hybrid automatic repeat request negative acknowledgement (HARQ NACK) to the second apparatus through physical sidelink feedback channel (PSFCH) based on information on a location of the first apparatus being not available and HARQ NACK-only feedback option being applied by the SCI, wherein a transport block (TB) related to the SCI is not decoded by the first apparatus.

Abstract: A method and apparatus for triggering of transmission carrier or resource reselection in a wireless communication system is provided. A first wireless device reserves a set of resources comprising at least a first resource and a second resource for sidelink transmission. When (i) the sidelink transmission using the first resource overlaps with an uplink transmission, and (ii) a priority of the uplink transmission is higher than a threshold, the first wireless device clears the first resource from the set of resources, and adds a third resource to the set of resources.

Abstract: A method for performing wireless communication by a first device and a device for supporting same are provided. The method comprises the steps of: mapping first sidelink control information (SCI) onto a resource related to a physical sidelink control channel (PSCCH); mapping a phase tracking-reference signal (PT-RS) onto a resource related to a physical sidelink shared channel (PSSCH), on the basis of a cyclic redundancy check (CRC) on the PSCCH; mapping second SCI onto a resource onto which the PT-RS is not mapped, among resources related to the PSSCH; and transmitting the first SCI, the second SCI, and the PT-RS to a second device, wherein the second SCI is not mapped onto a resource onto which the PT-RS is mapped.

Abstract: Proposed is a method for performing wireless communication by a first device. The method may comprise the steps of: transmitting sidelink control information (SCI) to a second device through a physical sidelink control channel (PSCCH) or a physical sidelink shared channel (PSSCH) related to the PSCCH, and transmitting data to the second device through the PSSCH related to the PSCCH. For example, the SCI may include position information of M number of resources related to previous transmission of a current time point, position information of a resource related to transmission of the current time point, and position information of P number of resources related to post-transmission of the current time point. For example, the value of the M may be 0 or a positive integer, and the value of the P may be 0 or a positive integer.
