摘要：
The present invention relates to a method and apparatus for transmitting a reference signal in a wireless communication system. A terminal generates a base sequence having a length of 12, for a reference signal, and determines a cyclic shift index from among a set of a cyclic shift indices {0, 3, 6, 8, 10}. The terminal cyclically shifts the base sequence on the basis of the determined cyclic shift index to generate a cyclically shifted sequence, and transmits the cyclically shifted sequence to a base station.
