1. A base station comprising:
a processor; and
a receiver configured to:
receive a first signal in a first portion of a subframe, and
receive a second signal in a second portion of the subframe,
wherein the first signal is based on a first Zadoff-Chu sequence and the second signal is based on a second Zadoff-Chu sequence,
wherein the first Zadoff-Chu sequence and the second Zadoff-Chu sequence are defined by a formula which comprises: Ck(n)=exp[−(j2πk/N)(n(n+1)/2+qn)], k in the formula is a parameter, and q in the formula is an arbitrary integer,
wherein a first value of the parameter for the first Zadoff-Chu sequence is different than a second value of the parameter for the second Zadoff-Chu sequence, and
wherein a value of the parameter is based on a cell identity.
