Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A user equipment (UE) configured to transmit an uplink signal to a base station (BS) in a wireless communication system, the UE 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:
mapping data modulation symbols and reference (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.
