Abstract
A method, an apparatus, and a device are provided for information transmission. In the method, the apparatus determines an initial OFDM symbol in OFDM symbols used to transmit load information. The apparatus determines, starting from the initial OFDM symbol, a phase deviation difference between two adjacent OFDM symbols according to first information to be transmitted. The apparatus performs phase deviation on at least one of the OFDM symbols according to the phase deviation difference. The apparatus then sends the OFDM symbols obtained after the phase deviation to a receiving end.
