Claim 17:
18. The base station of claim 17, wherein, in case that the message includes the second PRACH configuration index for the 2-step random access:
in case that the number of SSBs per PRACH occasion for the 2-step random access is smaller than 1, the contention based preambles with consecutive indexes associated with the SSB per valid PRACH occasion start from a preamble index 0, and
in case that the number of SSBs per PRACH occasion for the 2-step random access is larger than or equal to 1, the contention based preambles with consecutive indexes associated with the nth SSB per valid PRACH occasion start from a preamble index n*Npreambletotal′/N, the n being an SSB index and the Npreambletotal′ being a total number of preambles for the 2-step random access.
