Abstract:
1. A method of transmitting a reference signal in a wireless communication system, the method comprising: generating a length-12 base sequence for the reference signal; determining a cyclic shift index selected from a cyclic shift index based on at least one from a set {0, 3, 6, 8, 10}; generating a cyclically shifted sequence by cyclically shifting the base sequence on the basis of the cyclic shift index; and transmitting the reference signal based on the cyclically shifted sequence to a base station, wherein the reference signal is transmitted on a first orthogonal frequency division multiplexing (OFDM) symbol and a second OFDM symbol, wherein the first OFDM symbol is a second OFDM symbol among 7 OFDM symbols in one slot, and wherein the second OFDM symbol is a sixth OFDM symbol among the 7 OFDM symbols in the slot.
