Abstract
A communication method and apparatus are provided. The method includes: A terminal device determines a first sequence whose length is ΣK, and sends the first sequence on M subcarrier groups, where an isubcarrier group in the M subcarrier groups includes Ksubcarriers on a same symbol, i=0, 1, . . . , M−1, and frequency domain positions of subcarriers included in any two of the M subcarrier groups are different and belong to different symbols; and a sequence carried in each of the M subcarrier groups is a fragment of the first sequence, and fragments carried in any two subcarrier groups are different. According to the method, the terminal device sends the first sequence on the M subcarrier groups, so that interference between different terminal devices is small when channel estimation is performed by combining M symbols. This can effectively improve accuracy of channel estimation.
