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)?
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.
