- the information contained in the SIParaContainer is sorted and encoded according to the size of the SIB identifier, and/or the size of the internal IE sequence of the SIB. For example, IE1, IE2, and IE3 in SIParaContainer correspond to IE5, IE7, and IE10 of actual SIB1.
- the correspondence between the internal IE of the SIParaContainer and the IE in the actual SIB can be illustrated by the following table.
- the correspondence between the internal IE and SIB identifiers of the SIParaContainer and the internal IE identifier of the SIB is as follows:

- the IEs 1, 2, and 3 in the SI1container given by the CU correspond to the internal 2, 4, and 6 of the SI1 in the final version of the actual DU compilation.
- the IEs 1, 2, and 3 in the SI2container given by the CU correspond to the numbers 1, 8, and 10 of the SI2 in the final version of the actual DU compilation.
- the correspondence between the internal IE of the SIB and the IE of the final version of the actual DU compiled by the CU may be specified by the protocol, or may be provided by the CU.

- the CU may find the SIB included in the corresponding SI according to the mapping relationship between the SIB and the SI, and send the same to the UE through the RRC message.
- the message sent by the DU to the CU has the following format:
- the SI type and the SIB type may be mappings between the SIB and the SI.

- the CU finds the corresponding SI/SIB according to the SI/SIB type indication, and replaces the SI/SIB sent by the DU with the saved SI/SIB. In this way, the CU keeps the latest system message.
- the CU can reply by the RRC message at the first time. Another possible way is that the CU receives the RRC message requesting the other SI, but is not sure whether it is the latest version.
- the CU sends a other SI request to the DU, including the SI type/SIB type indication.
- the DU then sends the requested SI/SIB to the CU, and the CU may include the SI/SIB in the RRC message to reply to the UE.
- Optional specific example 3 The CU notifies the DU to broadcast the other SI, and specifically includes an SI type or an SIB type indication.

If the CU decides to reply by broadcast, or the protocol stipulates that the other SI can be sent by broadcast when the UE requests other SI through msg3. Then the CU needs to tell the DU which SI or SIB to broadcast.
- One possible way is to specifically indicate the system message related message sent by the CU to the DU, for example, by using a DL SI transfer (downlink system messaging message) or a broadcast SI indication (broadcast system indication) message.
