Patent ID: 10616026

Abstract:
The present disclosure discloses an Internet of Things communication method. In the present disclosure, a downlink data frame sent by the network side device includes a legacy preamble, a HEW preamble, and a data field; a subcarrier resource that is corresponding to the data field in a frequency domain includes at least one resource unit RU; and the RU is used to send a downlink IoT frame to the IoT terminal, where the downlink IoT frame includes an IoT preamble and an IoT data field, the IoT preamble is used to transmit physical layer control information of the downlink IoT frame, and the IoT data field is used to transmit downlink data between the network side device and the IoT terminal. According to the present disclosure, a network side device in a WLAN can schedule an IoT terminal, thereby reducing a conflict risk in an IoT communication process.
