Section: 5.2.2.3.1 Acquisition of MIB and SIB1
Content: The UE shall: 1> apply the specified BCCH configuration defined in 9.1.1.1; 1> if the UE is in RRC_IDLE or in RRC_INACTIVE; or 1> if the UE is in RRC_CONNECTED while T311 is running: 2> acquire the MIB, which is scheduled as specified in TS 38.213[ NR; Physical layer procedures for control ]  [13]; 2> if the UE is unable to acquire the MIB; 3> perform the actions as specified in clause 5.2.2.5; 2> else: 3> perform the actions specified in clause 5.2.2.4.1. 1> if the UE is in RRC_CONNECTED with an active BWP with common search space configured by searchSpaceSIB1 and pagingSearchSpace and has received an indication about change of system information; or 1> if the UE is in RRC_CONNECTED with an active BWP with common search space configured by searchSpaceSIB1 and the UE has not stored a valid version of a SIB or posSIB, in accordance with clause 5.2.2.2.1, of one or several required SIB(s) or posSIB(s) in accordance with clause 5.2.2.1, and, UE has not acquired SIB1 in current modification period; or 1> if the UE is in RRC_CONNECTED with an active BWP with common search space configured by searchSpaceSIB1, and, the UE has not stored a valid version of a SIB or posSIB, in accordance with clause 5.2.2.2.1, of one or several required SIB(s) or posSIB(s) in accordance with clause 5.2.2.1, and, si-BroadcastStatus for the required SIB(s) or posSI-BroadcastStatus for the required posSIB(s) is set to notBroadcasting in acquired SIB1 in current modification period; or 1> if the UE is in RRC_IDLE or in RRC_INACTIVE; or 1> if the UE is in RRC_CONNECTED while T311 is running: 2> if ssb-SubcarrierOffset indicates SIB1 is transmitted in the cell (TS 38.213[ NR; Physical layer procedures for control ]  [13]) and if SIB1 acquisition is required for the UE: 3> acquire the SIB1, which is scheduled as specified in TS 38.213[ NR; Physical layer procedures for control ]  [13]; 3> if the UE is unable to acquire the SIB1: 4> perform the actions as specified in clause 5.2.2.5; 3> else: 4> upon acquiring SIB1, perform the actions specified in clause 5.2.2.4.2. 2> else if SIB1 acquisition is required for the UE and ssb-SubcarrierOffset indicates that SIB1 is not scheduled in the cell: 3> perform the actions as specified in clause 5.2.2.5. NOTE 1: The UE in RRC_CONNECTED is only required to acquire broadcasted SIB1 and MBS broadcast if the UE can acquire it without disrupting unicast or MBS multicast data reception, i.e., the broadcast and unicast/MBS multicast beams are quasi co-located. The UE in RRC_INACTIVE state while SDT procedure is ongoing, is only required to acquire broadcasted SIB1 and MIB if the UE can acquire them without disrupting unicast data reception, i.e. the broadcast and unicast beams are quasi co-located. NOTE 2: UE in RRC_INACTIVE that does not support inactiveStateNTN-r17 enters RRC_IDLE upon cell reselection between TN cell and NTN cell, and initiates the NAS signalling connection recovery (see TS 24.501[ Non-Access-Stratum (NAS) protocol for 5G System (5GS); Stage 3 ]  [23]).
