    Dears,

    Could you please answer the following questions:
    1) What is the difference between the Fixed and the RR scheduling Algorithms? and which one is fairer?
    2) What is the change in the code if I want to use ‘fixed MU MIMO’ with Mode 4 (multi. antennas)?

    Regards

    Hi,

    1) The fixed scheduler assignes a pre-defined schedule while the RR scheduler assignes the same amount of resources in a cyclic fashion to the users. Therefore, the RR is the fairest in the sense that all the users get the same amount of resources over time.

    2) I am not quite sure if I understand this question entirely. Multi-user MIMO is a MIMO mode on its own and therefore has nothing to do with mode 4, which is a single-user MIMO mode.

    best
    Stefan
