Title:
DATA TRANSMISSION METHOD, APPARATUS, AND SYSTEM FOR DIRECT COMMUNICATION, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/133505
Kind Code:
A1
Abstract:
The present invention relates to the field of communications, and relates to a data transmission method, apparatus, and system for a direct communication of a direct communication, and a device. The method comprises: when direct Hybrid Automatic Repeat Request (HARQ) feedback information and uplink information need to be sent in a target time unit, and the direct HARQ feedback information and the uplink information satisfy a predetermined timing relationship, a first terminal sends the direct HARQ feedback information and the uplink information to an access network device on a same physical layer uplink channel in the target time unit. According to the present invention, in the manner described above, when the direct HARQ feedback information and the uplink information need to be sent in the target time unit, the direct HARQ feedback information and the uplink information satisfy at least the predetermined timing relationship to ensure that the first terminal can process the uplink multiplexing transmission in time. The success rate of information transmission and reception in a direct communication scenario is fully guaranteed.
