    Hi,
    For UFMC, in the following code

    % Parameters for UFMC
    scStr.modulation.nSubcarriersPerSubband = [12]; % number of subcarriers per subband

    This allow us to have 12 sub carrier per sub band. With combining the following line,

    % Numerology setup
    scStr.modulation.numerOfSubcarriers = [72]; % per BS; number of used subcarriers

    Hence we have 6 sub band each 12 sub carrier? I.e the sub band size always the same.

    Is there any possibility by allowing different sub carrier per sub band? So that the

    Thanks

    Hi,

    In the current implementation it is not possible to dynamically allocate different size of subbands within one user.
    If you want to change the number of subcarriers per subband, you can manually predefined obj.Nr.Subbands and the scStr.modulation.nSubcarriersPerSubband within each subband. In that situation you have to be aware of the subband filtering, and check whether it is enough accurate or not (for further information about this see Nokia’s proposal about UFMC).

    If you have two or more users, you can use different size of subcarriers per subband, simply adding the desired number in scStr.modulation.nSubcarriersPerSubband = [12, 6];, meaning that for the first user you have 12 subcarriers per subband, while for the second 6 subcarriers per subband.

    Best regards,

    Ljiljana
