Title
(EN) Direct communication data transmission method, device, equipment and system
(ZH) 直连通信的数据传输方法、装置、设备及系统
Abstract
(EN)
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.

本公开是关于一种直连通信的数据传输方法、装置、设备及系统,属于通信技术领域。所述方法包括:当需要在目标时间单元内发送上行HARQ反馈比特和直连HARQ反馈比特时,第一终端在目标时间单元内的同一个物理层上行信道上向接入网设备发送上行HARQ反馈比特和直连HARQ反馈比特。本公开通过上述方式将上行HARQ反馈比特和直连HARQ反馈比特复用起来,使用目标时间单元内的同一个物理层上行信道进行上报,避免了相关技术中直连HARQ反馈和上行HARQ反馈的传输在时间域上重合导致资源冲突的问题,充分确保了在直连通信场景中信息收发的成功率,且有助于提高HARQ反馈的传输效率。
