Classification: CPC H | IPC H

Claim 4:
5. An apparatus for transmitting a reference signal, comprising:
a processor and a memory including processor executable code, wherein the processor executable code upon execution by the processor cause the processor to:
obtain a sequence group number u of a 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 l2 of time domain symbols in which the reference signal is located among N time domain symbols included in one 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-the value in a sequence generated by a random sequence function c(·), and z is a non-negative integer;

determine the reference signal according to the sequence group number u; and
transmit the reference signal, wherein the following is satisfied:
D≥┌log2(C)┐+┌log2 (x1c┐−1;
x1=2┌log2(c)┐−C.
