RA-RNTI in RACH of 5G SA is based on what?

Hi Experts,
RA-RNTI in RACH of 5G SA based on what?
In 4G the calculation of ra-rnti based on time slot in which preamble was sent.
But in 5G SA I doubt if it’s the same as LTE calculation.

RA-RNTI= 1 + s_id + 14 × t_id + 14 × 80 × f_id + 14 × 80 × 8 × ul_carrier_id
Different from LTE that’s why I asked.
Because I didnt understand the implicitly meaning of those calculation over 5G.
