Abstract
A method includes: modulating, by using a binary phase shift keying BPSK manner of rotation by a first angle, at least partial signaling information carried in at least one signaling symbol in a signaling field of a data packet, to obtain modulated signaling information, where the first angle is not equal to 0 degrees or 90 degrees; and sending, to a receive end, the data packet that carries the modulated signaling information.
