Abstract
A device and method in which a plurality of Zadoff-Chu sequences is allocated to a frame, a value of a parameter in the Zadoff-Chu sequence is different among the plurality of Zadoff-Chu sequences, and the Zadoff-Chu sequence allocated to the frame is different among a plurality of cells.
Claims8
A mobile station comprising:
- a processor configured to:
- generate a first signal based on a first Zadoff-Chu sequence;
- generate a second signal 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;
- and
- a transmitter configured to transmit the first signal in a first portion of a subframe, and transmit the second signal in a second portion of the subframe.
