1. A method of transmitting an uplink signal by a user equipment (UE) in a wireless communication system, the method comprising:
mapping data modulation symbols and reference signal (RS) samples to a plurality of positions corresponding to a single orthogonal frequency-division multiplexing (OFDM) symbol prior to transform precoding;
applying the transform precoding based on the data modulation symbols and the RS samples, which are mapped to the plurality of positions; and
transmitting the uplink signal obtained based on a result of the transform precoding,
wherein mapping the data modulation symbols and the RS samples to the plurality of positions comprises:
mapping the data modulation symbols and the RS samples to the plurality of positions such that the plurality of positions include (i) a first plurality of RS samples, (ii) a second plurality of RS samples, and (iii) the data modulation symbols between the first plurality of RS samples and the second plurality of RS samples.
