CORESET#0 configuration with index 14. For a color version of this figure, see www.iste.co.uk/launay/5g.zip The position of CORESET#0 in the time domain is obtained by the values of TS 38.213 Table 13-11 whose row is calculated from the four least significant bits. CORESET#0 carries the sequencing information of the SIB1 system information. Once the MIB information has been decoded, the mobile will be able to recover the information transmitted by the broadcast message SIB1. The SIB1 broadcast message contains the Remaining Minimum System Information (RMSI): - the cell selection criteria; - the identity of the PLMN (Public Land Mobile Network); - the code of the TAC (Tracking Area Code); - the identity of the cell; - the unified access control of the UAC (Unified Access Control) cell; - the RAN (Radio Access Network) notification information; NG-RAN and 5G-NR - the resource allocation information for OSIs (Other System Information); - the common information of the service cell (ServingCellConfigCommon).
