==== 5.2.5.5 Reception of SIB1 ====

The Master Information Block (MIB) on Physical Broadcast Channel (PBCH) provides the UE with parameters (e.g. CORESET#0 configuration) for monitoring of PDCCH for scheduling PDSCH that carries the System Information Block 1 (SIB1). PBCH may also indicate that there is no associated SIB1, in which case the UE may be pointed to another frequency from where to search for an Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) block (SSB) that is associated with a SIB1 as well as a frequency range where the UE may assume no SSB associated with SIB1 is present. The indicated frequency range is confined within a contiguous spectrum allocation of the same operator in which SSB is detected.
