Abstract
Apparatuses, methods, and systems are disclosed for applying pre-filtered DFT-s-OFDM. One method includes receiving, at a device, an indicator indicating to apply pre-filtered discrete Fourier transform (DFT) spreading orthogonal frequency division multiplexing (OFDM) (DFT-s-OFDM) for transmission of at least one signal, reception of the at least one signal, or a combination thereof. The method includes, in response to the indicator indicating to apply the pre-filtered DFT-s-OFDM for transmission of the at least one signal, applying a filtering operation in a transmission chain before a DFT operation. The method includes, in response to the indicator indicating to apply the pre-filtered DFT-s-OFDM for reception of the at least one signal, applying the filtering operation in a reception chain after an inverse DFT (IDFT) operation.
