Erkan Okay,
If you´re using a reuse pattern like the one you just mentioned, The MAIO distribuition is correct… This way you will avoid co-channel and adjacent frequencies between co-site cells.
The HSN should be planned in a way that neighbours cells don´t have same HSN (it means they’ll hopp in differents pseudo-random sequences).
Remember of the basics, your network should be the most homogeneous possible (which means equals azimuths, no huge cells coverage overlaps, etc)
