Disclosed are a method for transceiving a reference signal in a wireless connection system and a terminal therefor. More particularly, the method comprises the steps of: generating a plurality of uplink reference signal sequences; mapping the generated plurality of uplink reference signal sequences to each of three symbols in one frame; and transmitting the mapped uplink reference signals to a base station. The plurality of uplink reference signal sequences is generated by applying an orthogonal cover code having a length of 3.
