1. A data transmission method, applied to a sending terminal device and comprising:
determining hybrid automatic repeat request (HARQ) feedback type configuration information of the sending terminal device, wherein the HARQ feedback type configuration information is configured based on service information of a service, and the service information comprises a quality of service (QOS) parameter of the service and/or group information of the service; and
sending a data packet to a receiving terminal device based on the HARQ feedback type configuration information;
wherein the determining HARQ feedback type configuration information of the sending terminal device comprises:
in a case that the sending terminal device is in a non-connected state, determining, according to a mapping rule in system information sent by a network device, the HARQ feedback type configuration information corresponding to the service information;
wherein the determining, according to a mapping rule in system information sent by a network device, the HARQ feedback type configuration information corresponding to the service information comprises at least one of:
determining the HARQ feedback type configuration information based on the number of receiving terminal devices in the group information and the maximum number of feedback positions of the service;
determining the HARQ feedback type configuration information based on the number of receiving terminal devices in the group information and the number of feedback positions in a transmission resource pool; and
determining the HARQ feedback type configuration information based on the number of receiving terminal devices in the group information, the maximum number of feedback positions of the service, and the number of feedback positions in the transmission resource pool.
