摘要： According to an example aspect of the present invention, there is provided a method, comprising: determining to perform frequency domain spectral shaping with spectrum extension to prepare a wireless transmission comprising an inband and an excess band comprising a first excess band portion and a second excess band portion, determining an excess band size, performing remapping of frequency domain resource elements of the inband on the basis of the excess band size, to fill the first excess band portion, and adding, in accordance with the excess band size, a cyclic extension to the second excess band portion based on at least one frequency domain resource element in the inband after said remapping.
