Abstract: A method and apparatus for hybrid automatic repeat request (HARQ) feedback based on a communication range and location of devices is provided. A first device (e.g., receiving user equipment in sidelink) receives, from a second device (e.g., transmitting user equipment in sidelink, control information including 1) a communication range, and 2) a location of the second device. The first device determines whether to perform a hybrid automatic repeat request (HARQ) feedback based on whether a distance between a location of the first device for the control information and the location of the second device is smaller or equal to the communication range.

Abstract: A method and appratus 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 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.
