Abstract: An example method includes generating, by a transmit end of a transceiver, NT beam training sequences, where each beam training sequence includes a cyclic prefix and a Golay sequence with a length of 2×N×L, and where the NT Golay sequences are orthogonal to each other. The transmit end can then send the NT beam training sequences to a receive end by using the NT transmit antennas at the transmit end, where each transmit antenna sends one corresponding beam training sequence.

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.

Abstract: In a data processing method, a transmit end may send, to a receive end, coding information of N layers of first bit sequences and second information that does not include some or all bits in the N layers of first bit sequences, and the receive end may process the coding information and the second information, to obtain the N layers of first bit sequences. Because the transmit end sends the coding information to the receive end, information sent by the transmit end may not include some or all bits in the N layers of first bit sequences.
