The application relates to a ZigBee-to-Lora cross-technology communication method based on a physical layer, wherein first, a ZigBee terminal encodes target data to be sent to obtain encoded data composed of one of binary numbers 0 or 1, and the encoded data is mapped to form a wireless data transmission signal for sending; then a Lora receiver identifies valid ZigBee data from the received wireless data transmission signal, further obtains corresponding encoded data through identification of a corresponding Fourier spectrum diagram; finally, the Lora receiver decodes and identifies the obtained encoded data according to the encoding rule of the ZigBee terminal, and obtains target data from the ZigBee terminal; the design method completes long-distance communication from the ZigBee terminal to the Lora receiver without the aid of an additional gateway, realizes efficient cross-technology communication, saves the hardware cost in an Internet of Things system, and improves the deployment speed of an Internet of Things data acquisition system.

The application provides a communication method and device to reduce the redundancy of cross-technology communication, and relates to the technical field of wireless communication. In the method, a first device acquires a first frame, and the first frame includes at least two first sequences. The first frame corresponds to a first communication protocol, and the first sequence corresponds to a second communication protocol. The first device scrambles the at least two first sequences to obtain a second frame. The second frame includes at least two second sequences, and the at least two second sequences are obtained by scrambling the at least two first sequences. The first device transmits the second frame. The second frame corresponds to a first channel, the at least two second sequences correspond to one or more second channels, and the first channel corresponds to the one or more second channels. Based on the above scheme, at least two first sequences corresponding to the second communication protocol can be carried in one frame, the proportion of redundancy in the frame can be reduced compared with the CTC method in the related art, the air interface occupation is reduced, and the packet sending efficiency is improved.
