Document Type and Number:
WIPO Patent Application WO/2021/052068
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a method and apparatus for data transmission in back reflection communication, and a system, which are used for improving the frequency spectrum utilization efficiency of data. Provided in an embodiment of the present application is a method for data transmission in back reflection communication, the method comprising: generating a first frame, the first frame carrying first data and second data, the first data and second data using different modulation means in the first frame, the first data being used for transmission to a first label, and the second data being used for transmission to a second label; and transmitting the first frame to the first label and the second label.
