Claim 5:
6. The method according to claim 4, wherein:
each of the K first symbols are different from each other, the K first symbols are generated based on ZC sequences in K third sets, each of the K third sets comprises M ZC sequences generated by performing cyclic shifting based on a u1th ZC sequence in a first set, and each of the Q second symbols is generated based on a u2th ZC sequence in a second set, wherein the first set comprises NU1 ZC sequences with different roots, the second set comprises NU2 ZC sequences with different roots, an intersection of the first set and the second set is an empty set, 1≤u1≤NU1, 1≤u2≤NU2, and M is an integer greater than or equal to 1;
the K third sets satisfy the following condition: CSi={i×NCS,1, i×NCS,2, . . . , i×NCS,M}, wherein i=1, . . . , or K, CSi represents a set of M cyclic shift offsets corresponding to M ZC sequences comprised in an ith third set, and 1≤i≤K; and
the K first symbols have a one-to-one correspondence with the K third sets, wherein an ith first symbol is generated using a ZC sequence whose cyclic shift offset is i×Ncs,m and that is in the ith third set, and 1≤m≤M.
