Abstract

The invention relates to a passive Internet of Things communication method and device, communication equipment and a computer readable storage medium. The method comprises the following steps: encoding a first signal to obtain a second signal, the first signal being any one of downlink signals; performing on-off keying (OOK) modulation on the second signal to obtain a third signal; performing discrete Fourier transform spread spectrum orthogonal frequency division multiplexing (DFT-s-OFDM) modulation on the third signal to obtain a fourth signal; and sending the fourth signal to the passive Internet of Things equipment. By adopting the method, the reliable transmission of the downlink signal of the communication physical layer of the passive Internet of Things can be realized.
