Abstract
A reference signal sending method includes obtaining a frequency-domain cyclic shift factor and a time-domain cyclic shift factor, wherein the frequency-domain cyclic shift factor and the time-domain cyclic shift factor are useable to perform phase rotation on a reference signal sequence. A reference signal sending method further includes generating a second reference signal sequence based on a first reference signal sequence, the frequency-domain cyclic shift factor, and the time-domain cyclic shift factor. A reference signal sending method further includes sending the second reference signal sequence on an antenna port p, wherein p is an element in a set {0, 1, . . . , P−1}, and P is an integer greater than or equal to 1.
