Claim 12:
13. A base station (BS) configured to receive an uplink signal from a user equipment (UE) in a wireless communication system, the BS comprising:
a transmitter;
at least one processor; and
at least one computer-readable memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, control the UE to perform operations comprising:
receiving the uplink signal of a single orthogonal frequency-division multiplexing (OFDM) symbol transmitted using transform precoding; and
obtaining data modulation symbols and reference signal (RS) samples based on the uplink signal,
wherein the data modulation symbols and RS samples are mapped to a plurality of positions corresponding to the single OFDM symbol prior to the transform precoding 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.
