Classification: CPC H | IPC H

Claim 15:
16. A communication apparatus, comprising at least one processor and a transceiver, wherein the at least one processor is coupled to the transceiver;
the transceiver is configured to receive a first signal carried on N subcarrier groups, and obtaining a sequence that is carried by the first signal and that is in an ith subcarrier group in the N subcarrier groups, wherein N is a positive integer greater than or equal to 1, the sequence is a first segment of a sequence {zq(m)}; a length of the sequence {zq(m)} is M; the sequence meets zq(m)=yq(m mod Mzc), wherein m=0, 1, 2, . . . , M−1, M is an integer greater than 1, Mzc is a maximum prime number that is less than M or a minimum prime number that is larger than M; and Ki<Mzc/2, yq(t)=A·exp(jαt)exp, K

  ,, wherein A is a non-zero complex constant, t=0, 1, 2, . . . , Mzc−1, j=√{square root over (−1)}, α is a real number, q is determined based on an identifier of the first signal or a cell identifier, and q=└q+½┘, wherein q=Mzc·(nid+1)/p, nid∈{0, 1, 2, . . . , p−2}, p is a prime number greater than 2, and nid is determined based on the identifier of the first signal or the cell identifier; and
the at least one processor is configured to process the first signal.
