Section: 5.2.2 System information acquisition 5.2.2.1 General UE requirements
Content: Figure 5.2.2.1-1: System information acquisition The UE applies the SI acquisition procedure to acquire the AS, NAS- and positioning assistance data information. The procedure applies to UEs in RRC_IDLE, in RRC_INACTIVE and in RRC_CONNECTED. The UE in RRC_IDLE and RRC_INACTIVE shall ensure having a valid version of (at least) the MIB, SIB1 through SIB4, SIB5 (if the UE supports E-UTRA), SIB11 (if the UE is configured for idle/inactive measurements), SIB12 (if UE is capable of NR sidelink communication/discovery and is configured by upper layers to receive or transmit NR sidelink communication/discovery), and SIB13, SIB14 (if UE is capable of V2X sidelink communication and is configured by upper layers to receive or transmit V2X sidelink communication), SIB15 (if UE is configured by upper layers to report disaster roaming related information), SIB16 (if the UE is capable of slice-based cell reselection and the UE receives NSAG information for cell reselection from upper layer), SIB17 (if the UE is using TRS resources for power saving in RRC_IDLE and RRC_INACTIVE), SIB19 (if UE is accessing NR via NTN access) and SIB22 (for ATG access). The UE capable of MBS broadcast which is receiving or interested to receive MBS broadcast service(s) via a broadcast MRB shall ensure having a valid version of SIB20, regardless of the RRC state the UE is in. The UE shall ensure having a valid version of the posSIB requested by upper layers.
