1. An information indication method, comprising:
generating, by a transmit end, a Physical Layer Convergence Protocol Data Unit (PPDU) including radar indication information, wherein the radar indication information is configured to indicate that the PPDU is used for radar testing, the radar indication information is located at a MAC layer in the PPDU, and the radar indication information comprises a Type field with a value of 11 and a Subtype field with a value of any one of 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, or 1111; and
transmitting the PPDU to a receiving device, wherein the receiving device is configured with a monitoring function which monitors a channel for data communication from the transmit end, wherein the PPDU specifies to the receiving device to turn off the monitoring function for a period of time specified by the PPDU, to thereby reduce power consumption of the receiving device.
