Methods, systems, and devices for wireless communications are described. A transmitting device may filter data tones (e.g., in edge subbands of an allocated frequency band) to achieve time domain windowing or shaping. Data tones of edge subbands of a configured frequency band may be filtered to shape a waveform such that it does not extend beyond symbol boundaries (e.g., does not result in emission leakage). In some examples, the transmitter may provide an indication of subband frequency domain shaping filters used to the receiver, to support demodulation on the receiver side. In some examples, the transmitter may indicate a demodulation reference signal (DMRS) comb structure (e.g., of the edge subbands) to the receiver, and the receiver may determine or estimate the filters of the subband frequency domain shaping based on the comb structure or the indication of the filters.
