BSIC is to differantiate bcch’s, so dont give bcch-bsic combination if possible(or give to cells far)
if u have a common MA list(1×1 or 1×3 sfh case) dont give same hsn to close sites and to cells of a site give same hsn’s
MAIO depends on ur trx number and hopping model(u will find lots of topics about this in the forum)
