The invention provides a beam matching method and a communication device. The beam matching method includes the following steps that: a beam scanning parameter group is determined, wherein the scanning parameter group includes M, P, and Q, wherein M refers to the number of time-domain repetition signals in one OFDM symbol, P refers to the length of a 0 sequence between two adjacent time-domain repetition signals in the OFDM symbol, and Q refers to the length of the 0 sequence between a cyclic prefix and the first time-domain repetition signal in the OFDM symbol; the beam scanning parameter group is transmitted to a receiving end device; and pilots are transmitted based on the beam scanning parameter group, so that beam scanning can be transmitted or received. With the beam matching methodand the communication device provided by the technical schemes provided by the present invention adopted, some gaps, such as the 0 symbol sequence, can be interpolated to both sides or one side of thetime-domain repetition signals; in addition, due to the presence of the gaps, a traditional interleaved frequency division multiple access (IFDMA) scheme can be improved to support the transmitting or receiving of beam scanning in the time domain.
