11. A method comprising:
receiving, by a user equipment from a network node, a configuration message for frequency domain spectral shaping, wherein the configuration message is indicative of at least one or more filter parameters, wherein the one or more filter parameters comprise at least error vector magnitude equalizer spectral flatness requirements;
determining a frequency domain window function according to the one or more filter parameters; and
transmitting an uplink transmission applying the determined frequency domain window function.
