IEEE/ICACT20230137 Slide.10        [Big Slide]       [YouTube] Oral Presentation
This slide shows the initial access process based on 5G NR. Unlike in LTE, if MIB and SIB1 messages are received after starting cell search, RRC connection is established by immediately attempting RANDOM ACCESS in the CAMPED NORMALLY state. The reason why RANDOM ACCESS can be performed without receiving SIB2 in 5G NR is that RACH information is included in SIB1 as confirmed in the table on the previous slide.
