I did not set anything explicitly, although I did not set in my xxx block the set relative rate (maybe that is used by the scheduler to set up the buffer sizes appropriately). Basically I want to take 100 packets of size 160 and push them through an S/P converter for an 128 point IFFT (think of OFDM where every subcarrier would carry its own packets independently).
