    I understand 3D channel.

    Is 3D channel with UPA implemented?

    but I want to know if KPC(Kronecker Product codebook) is applicable.
    In order to apply KPC, 2D structure channel is required.

    Links to related papers are as follows.

    However, if a vertical channel is mapped to one antenna port
    Is there a way to know the vertical channel?

    Dear Kim,

    The structure of suported planar antenna arrays is very flexible, you can change the vertical mapping into some other structure of antenna element mapping and apply different 2D precoders. In +channel_gain_wrappers\TR36873_Fading_3D_Channel.m, in the function calculate_channel_coefficient_xxxx you can adapt the loop of generating the channel coefficients (i.e., ‘for mm = 1:LTE_config.nr_of_antenna_elements_in_each_column’) according to the mapping you want to use.

    Best regards,
    Fjolla
