Claim 7:
8. An apparatus, comprising:
a storage medium including executable instructions; and
at least one processor;
wherein the executable instructions, when executed by the at least one processor, cause the apparatus to:
determine a second sequence based on an index v of a sequence group, wherein the sequence group comprises a sequence {xn} and a sequence {ym}, and wherein the second sequence is at least one of a second sequence {fn} or a second sequence {gm}; and
receive uplink control information or a reference signal based on the second sequence, wherein:
the sequence {xn} corresponds to a second sequence {fn}, and the second sequence {ym} corresponds to the second sequence {gm}, wherein fn is an element in the second sequence {fn}, gm is an element in the second sequence {gm}, a length of the second sequence {fn} is N, a length of the second sequence {gm} is M, n and m are integers, 0≤n≤N−1, and 0≤m≤M−1;
the element fn satisfies fn=xn·ej·α·n;
the element gn satisfies gm=ym·ej·α·m; 
A is a non-zero complex number, a is a real number, and j=√{square root over (−1)};
an element xn in the sequence {xn} satisfies xn=u·eπ·j·sn/4, u is a non-zero complex number, and sn is an element in a sequence {sn};
an element ym in the sequence {ym} satisfies ym=kq(m mod Mprime),, k
