Title
(EN) DATA TRANSMISSION METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL DE TRANSMISSION DE DONNÉES
(ZH) 一种数据传输方法及装置
Abstract
(EN) A data transmission method and apparatus. The method comprises: a first communication apparatus determining a first HARQ process according to preemptive mode information and/or preemptive principle information; and the first communication apparatus receiving first data by means of the first HARQ process, wherein the first HARQ process is a preempted HARQ process. In the technical solution, insofar as all the HARQ processes are preempted and the first data from a second communication apparatus needs to be received, the first communication apparatus is provided with a behavior of receiving the first data by means of the first HARQ process, thereby facilitating improvements in the reliability of the first communication apparatus when receiving data, and reducing the delay of the first communication apparatus when receiving data.
(FR) La présente invention concerne un procédé et un appareil de transmission de données. Le procédé comprend les étapes suivantes : un premier appareil de communication détermine un premier processus HARQ selon des informations de mode préemptif et/ou des informations de principe préemptif; et le premier appareil de communication reçoit des premières données au moyen du premier processus HARQ, le premier processus HARQ étant un processus HARQ préempté. Dans la solution technique, si tous les processus HARQ sont préemptés et que les premières données provenant d'un second appareil de communication doivent être reçues, le premier appareil de communication présente un comportement de réception des premières données au moyen du premier processus HARQ, ce qui facilite les améliorations de la fiabilité du premier appareil de communication lors de la réception de données et qui réduit le retard du premier appareil de communication lors de la réception de données.
(ZH) 一种数据传输方法及装置,所述方法包括:第一通信装置根据抢占模式信息和/或抢占原则信息,确定第一HARQ进程;所述第一通信装置通过所述第一HARQ进程接收第一数据;其中,所述第一HARQ进程是被占用的HARQ进程。该技术方案中,第一通信装置在HARQ进程均被占用且需要接收来自第二通信装置的第一数据的情况下,为第一通信装置提供一种行为,通过第一HARQ进程接收第一数据,有助于提升第一通信装置接收数据的可靠性、降低第一通信装置接收数据的时延。
