Abstract
A backscatter communication method and apparatus provides operation including: receiving a first excitation signal from a first device; determining a first resource based on a candidate resource; and sending a backscattered signal of the first excitation signal to a second device based on the first resource. This can reduce a probability of selecting a same resource as another device to some extent, so that a conflict is reduced, and an access success rate of a backscatter device can be improved.
