name: SIB20
full_form: System Information Block Type 20
context: An MBS capable UE interested to receive or receiving an MBS broadcast service shall: 1> if the procedure is triggered by an MCCH information change notification: 2> start acquiring the MBSBroadcastConfiguration message on MCCH in the concerned cell from the slot in which the change notification was received; 1> if the UE enters a cell providing SIB20; or 1> if the UE receives sCellSIB20: 2> acquire the MBSBroadcastConfiguration message on MCCH in the concerned cell at the next repetition period.
description: System Information Block Type 20 (SIB20) is a specific type of system information block that contains essential details about the Multicast Broadcast Single Frequency Network (MBSFN) configuration. It is used by the UE to acquire MBS broadcast service information when entering a cell providing SIB20 or upon receiving sCellSIB20.
explanation: SIB20 is classified as a Message because it refers to a specific type of system information block that carries critical details about MBSFN configuration, which is used by the UE for acquiring MBS broadcast service information. This classification aligns with the context provided in 3GPP TS 38.331, where SIB20 is mentioned as a key component in the process of MCCH information acquisition by the UE.
