Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A data transmission method for direct communication, comprising:
when direct hybrid auto repeat request (HARQ) feedback information and uplink information sent by the first terminal are to be received within a target time unit, and the direct HARQ feedback information and the uplink information satisfy a predetermined timing relationship, receiving, by an access network device, the direct HARQ feedback information and the uplink information sent by the first terminal on the same physical layer uplink channel within the target time unit;
wherein, the direct HARQ feedback information is configured to indicate a receiving state corresponding to direct data, and the direct data is physical layer data sent by the first terminal to a second terminal through a direct link;
wherein the predetermined timing relationship comprises:
a first time point being prior to a second time point, and an absolute value of a difference between the first time point and the second time point being greater than a predetermined processing time length;
wherein, the first time point is an end transmission time point of the direct HARQ feedback information on a direct feedback channel, and the second time point is a start transmission time point of the uplink information on the physical layer uplink channel.
