Dear friends,
I have question regarding to PCI:
As I know PCI is like Scrambling Code in WCDMA to distinguish cells, if I am not wrong.
And it the combinations of SSS & PSS (PCI = 3*SSS+PSS).
My question: in some document I saw that we should not use PSS (exp "0") in the cell of the same site and in the neighbors due to MOD3 rule. I don't understand that how is it possible not to use, it is just three values in PSS (0,1,2).
Yesterday I saw in one book, the author mentioned that it is not advisable to use PCI 22 & PCI 28 in the neighbour cell, because their PSS is 1.
So in this case how can we make PCI planning between cells??? Same explanations also were mentioned in Harish Vadada PCI Planning Document.
If some of you have experience and detail (in simple way :)) explanation for PCI planning and the meaning of MOD3/MOD6/MOD30 rules, then can you share with us your skills?
Thanks in advance
