Abstract
A signal sending method, a signal detection method, and an apparatus are disclosed. In the signal sending, a sequence of a reference signal is generated first, where the cyclic shift value of the sequence is determined based on a first parameter and a second parameter, the first parameter is a value from 0 to Q−1, the second parameter is a value from 0 to Z−1, Z and Q are positive integers, and Z is not equal to Q. The reference signal is then sent based on the sequence. According to the method, a difference between the cyclic shift values used by any two terminal devices to determine the sequences of reference signals can be randomized. Further, interference between reference signals generated by using the cyclic shift values obtained by terminal devices according to the method disclosed here can be reduced, the interference can be randomized, and the channel time-domain filtering performance can be improved.
