Abstract

本申请公开一种数据传输方法及通信装置，用于减少系统开销，提高重传效率。该方法包括：从网络设备接收下行控制信息DCI，其中，所述DCI包括第一比特和第二比特，所述第一比特和所述第二比特分别用于指示与所述DCI调度的两个传输块TB关联的两个新数据指示NDI；根据所述DCI中的所述第一比特和所述第二比特，在所述两个TB对应的HARQ进程上进行上行数据传输或下行数据传输。通过一个DCI承载该DCI调度的两个TB关联的两个NDI，尽可能地不增加DCI开销。同时，由于是通过DCI中的第一比特和第二比特分别指示两个两个TB关联的NDI，也就是通过不同的比特指示位对不同的NDI进行独立指示，这样能够准确区分哪个TB需要重传，提高重传效率。本申请实施例提供的方法和设备提高了网络的覆盖能力，可以应用于物联网，例如MTC、IoT、LTE‑M、M2M等。
