Abstract | A communication method and apparatus are disclosed. The method includes: determining, by a terminal device, a preamble, where the preamble includes M symbol groups, where M is a positive integer greater than 1; and sending, by the terminal device, the M symbol groups in K uplink subframe sets, where any uplink subframe set in the K uplink subframe sets includes one uplink subframe or more than one consecutive uplink subframes, any two uplink subframe sets in the K uplink subframe sets are spaced by at least one downlink subframe, and in each of the K uplink subframe sets at least one symbol group can be sent, where K is a positive integer greater than 1, and K is less than or equal to M; and N times of frequency hopping exist in the M symbol groups, each of the N times of frequency hopping is frequency hopping between adjacent symbol groups in the M symbol groups, and frequency hopping directions of at least two of the N times of frequency hopping are opposite, where N is less than M. |
