1. A method for receiving a downlink signal by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station (BS), a physical downlink control channel (PDCCH) based on a DFT-s-OFDM (Discrete Fourier Transform-spread-Orthogonal Frequency Division Multiplexing) symbol; and
obtaining downlink control information (DCI) from the received PDCCH,
wherein the DFT-s-OFDM symbol for the PDCCH is generated by i) applying one or more DFT operations to modulation symbols for the PDCCH and ii) applying one inverse fast Fourier transform (IFFT) operation to an output of the one or more DFT operations, and
wherein a plurality of modulation symbols being input for at least one of the one or more DFT operations, among the modulation symbols for the PDCCH, constitutes one resource group.
