In LTE RACH preamble is transmitted in entire 6RB's and 14 OFDMA symbol.
But in NR RA-RNTI calculation specification shows RA-RNTI= 1 + s_id + 14 × t_id + 14 × 80 × f_id + 14 × 80 × 8 × ul_carrier_id
Where s_id is OFDMA symbol position. 0=<s_id<=14. Does this means preamble can be transmitted any of the 14 OFDMA symbol.
