Hello Experts,
I’m trying to understand the calculation of RACH where it can be transmitted in symbols.
My PRACH index is 75, so according to the table I have some relevant values abd have the formula for calculating the slits of where the rach can be transmitted.
It’s 5g NR SA.
l = {14,20} where RACH can be transmitted in symbols (slots) 14 and 20 for 60 kHz.
But my SCS is 120 kHz so how I can find out the slots of 120 SCS?
Here is the formula:
Try here:

Click on 75 link.
Yes I understand but once again how do I find the slots?
For instance here it’s 35, 39, 75, …,159.
I mean how did we calculate those slots?
By giving us the table of PRACH index of course. It given us information to formula as I showed above.
But it’s for 60 kHz and not for 120 kHz.
It is for 120 KHz:

I understand but it’s like already calculating and not shown how to calculate those slots .
So my query is like we dont need to calculate?
Just to refer to that table?
I mean we don’t need to concern on how to calculate the slots mathmatically, just to refer to that table? For all prach indexes the slots already calculated.
