1. A method for transmitting a reference signal, the method performed by a wireless device comprising:
generating a pseudo-random sequence c(i) defined by
c(i)=(x(i+Nc))mod 2
x(i+31)=(x(i+3)+x(i))mod 2
y(i+31)=(y(i+3)+y(i+2)+y(i+1)+y(i))mod 2
where x(i) and y(i) are m-sequences and Nc is a constant;
generating a reference signal sequence based on the pseudo-random sequence; and
transmitting the reference signal sequence,
wherein the pseudo-random sequence c(i) is initialized with an initial value obtained by using (2 NIDcell+1), where NIDcell is a cell identifier of the cell.
