Internet of things communication method, network side device, and internet of things terminal

An Internet of Things (IoT) apparatus, comprising a processor and a computer readable storage medium storing instructions, which when executed by the processor, instruct the apparatus to:

• receive a downlink signal sent by a network side device;
• and
• acquire a downlink data frame from the received downlink signal, wherein the downlink data frame comprises a preamble and a data field, and wherein subcarrier resources corresponding to the data field in a frequency domain comprise at least one resource unit (RU) including a downlink IoT frame in the data field, the downlink IoT frame comprising an IoT preamble and an IoT data field, wherein the IoT preamble carries physical layer control information of the downlink IoT frame and the IoT data field carries downlink data between the network side device and a IoT terminal, and
• process the downlink IoT frame in the data field to obtain the downlink data between the network side device and the apparatus, wherein the physical layer control information includes one or any combination of the following sequences:
• a synchronization sequence used by the IoT terminal to obtain timing synchronization and frequency synchronization of the downlink IoT frame;
• or
• a training sequence used by the IoT terminal to obtain channel estimation required for demodulating the downlink IoT frame.
