hi lucka,
you should go either for odd MAIO planning OR even MAIO planning means that 4/4/4 then 1/3/5,7/9/11,13/15/17,19/21/23 like wise for sectors TRXs if ur frequencies are continous and u can use continous MAIO if ur frequencies are ALTERNATE like 31,33,35…….,like that.MAIO is basically a counter to ensure same frequency not to be emitted from any TRX at same time.
