Abstract
The present disclosure relates to beam training sequence design methods and apparatus. One example method includes generating NT beam training sequences, where each beam training sequence includes a cyclic prefix and (2×N) Golay sequences, each Golay sequence is with a length of L, and the NT beam training sequences are orthogonal to each other, and sending the NT beam training sequences using NT transmit antennas, where each transmit antenna of the NT transmit antennas sends one beam training sequence of the NT beam training sequences.
