Claim 0:
1. A method for generating a sequence of a reference signal, comprising:
receiving the reference signal;
determining a sequence group number u of the reference signal according to
u=(fgh(x)+fss)mod C, wherein C is a total number of sequence groups, fss is a parameter included in a higher-layer signaling, fgh(x) is a function with respect to x, x comprises at least one of the following pieces of information:
a number N of time domain symbols included in a time unit in which the reference signal is located;
index information l 2 of time domain symbols in which the reference signal is located among the N time domain symbols included in the time unit; or
a time unit index ns obtained according to a subcarrier spacing of a bandwidth part (BWP) in which the reference signal is located; and

wherein fgh(x)=(ΣI=0D−1c(D*h( )+i)*2i)mod C, wherein:
h( )is a function with respect to l2, ns, and N,
0≤l2<N,
D is an integer equaling to 8,
c(z) is a z-th value in a sequence generated by a random sequence function c(·), and z is a non-negative integer; and

generating the sequence of the reference signal according to the determined sequence group number u, wherein the following is satisfied:, D
