For LTE system messages, which of the following statements are correct?

Except for SIB1, SIB2-SIB13 are all carried by SI (System Information), and SIB2 must be mapped in the first SI message.

The Scheduling InfoList in SIB2 carries the scheduling information of all SIs. After receiving SIB2, other SI messages can be received.

SIB1 and all SI messages are transmitted on BCCH → DL-SCH → PDSCH.

The transmission of SIB1 is completed through PDCCH scheduling carrying SI-RNTI (SI-RNTI is the same for each cell).
