Title:
DATA TRANSMISSION METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/029162
Kind Code:
A1
Abstract:
A data transmission method, device and system, which can implement the compatibility of an NB-IoT system with TDD technology in an LTE system, and improve the utilization rate of a spectrum resource for data transmission between a base station and a UE. The specific solution comprises: a base station sends an NPSS to a UE by using first sub-frames in a first radio frame and a second radio frame, the first radio frame and the second radio frame being continuous, and the first radio frame and the second radio frame using TDD uplink and downlink sub-frame configurations; the base station sends an NPBCH to the UE by using second sub-frames in the first radio frame and the second radio frame; the base station sends an NSSS to the UE by using a third sub-frame in the first radio frame; the base station sends a SIB1-NB to the UE by using a third sub-frame in the second radio frame.
