Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 4:
5. A receiving device comprising:
communication circuitry configured to:
transmit, to a communication apparatus, first control information indicating whether a Discrete Fourier Transform-spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) transmission scheme or an OFDM transmission scheme is to be performed; and
receive modulated symbols from the communication apparatus, the modulated symbols having been precoded with a precoding matrix selected from among precoding matrices if the first control information indicates that the DFT-s-OFDM is to be performed, the precoding matrices including a first matrix according to which phase shift is performed on at least one symbol of the modulated symbols; and

a processor configured to:
perform signal processing on the modulated symbols according to the first control information;
select a demodulation scheme from among demodulation schemes, the demodulation schemes including π/2-shift Binary Phase-Shift Keying (BPSK) scheme; and
demodulate the modulated symbols to generate encoded information according to the demodulation scheme selected.
