If the preamble format determines the cell radius, than how is it possible to use ncs 12+ with preamble format = 0 (i.e. prach config index 9,10,11).? If I use ncs=13+ do I have to use other preamble format? A lot is explained on the internet but I cannot find any clear correlation between ncs and preamble format. Does the CS length has to be smaller od equel than CP lenght which is determined by the preamble format? Can a CS length be larger than CP length?
It seems to me that this post could be helpful.
