Question

What is PRACH Resource Index?

Answer 1

Hi sivakumar,

There is no resource index. It is either PRACH frequency offset or PRACH MASK index.

PRACH frequency offset : This will tel which frequency to use to send preamble (exactly starting RB out of 94 in 20mhz).

PRACH MASK index: This is dedicated configuration which is used for contention free rach. This will tel which PRACH resource SF to use in available PRACH resource.

Happy Learning :)
