Abstract
A communication method and apparatus. A second device determines a first sequence, the first sequence being associated with a first parameter, a second parameter and a third parameter, the first parameter indicating a root index of the first sequence, the second parameter indicating an index of an element included in the first sequence, the second parameter being an integer less than or equal to N-1 and greater than or equal to 0, N being a number of frequency domain units occupied by a first frequency domain resource, the first frequency domain resource being used to transmit a signal determined according to the first signal sequence, the third parameter having a value being an integer greater than or equal to 0 and less than a length of the first sequence, N not being equal to the length of the first sequence. A first device generates a first signal sequence according to the first sequence. By adding the third parameter, the change of the sequence is more diverse, thereby expanding the number of sequences.
