sending a first data frame to a relay device, the first data frame comprising a first preamble and a first information set, and the first preamble being used to wake up the relay device;
sending a second data frame to the relay device, the second data frame comprising a second preamble and a second information set, the second data frame being sent after the terminal has sent the first data frame and a first time interval has elapsed, and a length of the second preamble being less than that of the first preamble; and
receiving a third data frame sent by the relay device, the third data frame being sent to the terminal after being received from a base station by the relay device.
