PRACH Planning in LTE

[forumuser-2008]

Dear Friends,

I am looking for book which describes PRACH Planning in LTE. But no any normal information about that in the internet.
If some of you have experience in this work, could you describe please? How is it possible to start plan RSI (Root Sequence Index) for new network? If you wish you can check the following questions:

1. Is it possible to use 839 ZC sequence for all the sites? I mean should I leave any step (exp.: 10, 20, 30 or can I use 10, 11, 12) for one site
2. If preamble format is "0", so maximum cell range is 15km if I am not wrong. Should I define only one RSI for one cell or need more?
3. If you have experience in Huawei, then could you share your experience?

etc...

Thanks in advance

Hi ,
I've prepared a few slides dedicated on PRACH planning in LTE.
Based on the examples you'd get clearer view of the PRACH planning concept, I hope

Thanks Incoincov,

I have a following questions:

1. How did you calculate Root Sequence Index for the following example? Is it possible to use RSI like 0,1,2 or 25,26,27 not to leave step between indexes?
2. In our network I see that (Huawei) PRACH Configuration Index is NULL (not configured). How is it possible?

Hi,

Pls go more carefully through the material i've attached. The answers to your questions are inside. Pls refer to the tables in order to realize how the parameter values are defined. The examples will also help you.
Pls note that there are logical and physical RSIs.
