Section: – DLInformationTransfer
Content: The DLInformationTransfer message is used for the downlink transfer of NAS dedicated information, timing information for the 5G internal system clock, or IAB-DU specific F1-C related information. Signalling radio bearer: SRB2 or SRB1 (only if SRB2 not established yet). If SRB2 is suspended, the network does not send this message until SRB2 is resumed. If only dedicatedInfoF1c is included, SRB2 is used.
