1. A method for transmitting a reference signal, by a user equipment, in a wireless communication system, the method comprising:
generating a plurality of reference signal sequence by cyclically shifting a base sequence xu(n); mapping each of the plurality of reference signal sequence to a corresponding single carrier frequency division multiple access (SC-FDMA) symbol among a plurality of SC-FDMA symbols in a subframe to form the reference signal, the subframe including the plurality of SC-FDMA symbols in a time domain and two resource blocks in a frequency domain, the each resource block including 12 subcarriers; and transmitting the reference signal, wherein the base sequence xu(n) is expressed by
xu(n)=ejp(n)π/4, and at least one of the sets of values provided in the below table is used as a set of values for the phase parameter p(n):p(0), . . . , p(23)−1−33−1−1−1−111−331331−11−31−311−3−1−1−33−3−3−3−1−1−3−1−3313−3−13−11−13−31−1−1−11−313−31−1−3−13131−1−3−3−1−1−3−3−3−1−1−3113−311−3−1−113131−1311−3−1−3−1−1−3−1−11−3−1−11−1−311−31−3−3311−13−1−1 |
