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.

A first wireless device transmits a first sidelink transmission via a first resource, where the first sidelink transmission includes a field indicating resource reservation of a second resource for a second sidelink transmission by the first wireless device. Based on an absence of an acknowledgement (ACK) corresponding to the first sidelink transmission, the first wireless device determines to use the second resource to receive inter user equipment (inter-UE) coordination information from a second wireless device. The first wireless device receives, from the second wireless device and based on the determining, the inter-UE coordination information indicating a set of third resources for one or more third sidelink transmissions by the first wireless device.

A method for a first device to perform wireless communication and a device supporting same. The method may include: receiving, from the base station through a second PDCCH, a second DCI including information related to a second SL resource and information related to a second PUCCH resource; transmitting a first physical sidelink shared channel (PSSCH) based on the first SL resource; and transmitting, to the base station through the second PUCCH resource, first hybrid automatic repeat request (HARQ) feedback information related to the first PSSCH and second HARQ feedback information related to the second PSSCH, based on a slot including the first PUCCH resource being same as a slot including the second PUCCH resource, wherein the second DCI is a last DCI among a plurality of DCIs including information related to the slot for PUCCH transmission.
