Abstract

The invention discloses a direct communication data transmission method, device, equipment and system, and belongs to the technical field of communication. The method comprises: when an uplink HARQ feedback bit and a direct connection HARQ feedback bit need to be sent within a target time unit, the uplink HARQ feedback bit and the direct connection HARQ feedback bit are sent to a facility that isaccessed to the network by a first terminal in a same physical layer within the target time unit. The uplink HARQ feedback bit and the direct connection HARQ feedback bit are compounded and reported in a same physical layer within the target time unit to avoid the problem that in related technologies, transmission of direct connection HARQ feedback and transmission of uplink HARQ feedback are overlapped in time domain, and resource conflict happens. The provided method can fully ensure the information transceiving success rate in a direct connection communication scene and improves the transmission efficiency of HARQ feedback.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular to a data transmission method, device, device and system for direct communication. Background technique [0002] In the Vehicle to Everything (V2X) technology, a vehicle-mounted device can communicate directly with other devices (such as other vehicle-mounted devices, roadside infrastructure, etc.) through a side link (English: sidelink). Direct communication has the characteristics of short delay and low overhead. [0003] In related technologies, the direct connection communication method based on access network device scheduling includes: the access network device sends scheduling information to the direct connection communication sender user equipment (referred to as: first terminal), the first terminal sends the direct connection data to the user equipment at the receiving end of the direct connection communication through the sidelink according to the sched...
