Abstract
A data transmission method, apparatus, device and system for direct communication are provided. The method includes that a first terminal sends, according to information sent by an access network device, sidelink data to a second terminal through a sidelink. The first terminal receives sidelink hybrid auto repeat request (HARQ) feedback information fed back by the second terminal, where the sidelink HARQ feedback information is configured to indicate a receiving state corresponding to the sidelink data. The first terminal reports the sidelink HARQ feedback information to the access network device.
