Question: What is the primary mechanism for conveying sidelink common control information in NR (New Radio) sidelink communication/discovery/positioning?
Option 1: SystemInformationBlockType1 (SIB1)
Option 2: MasterInformationBlock (MIB) for general system information
Option 3: MasterInformationBlockSidelink (as specified for sidelink operations)
Option 4: UE-specific Radio Resource Control (RRC) signaling
Explanation: In the context of NR sidelink communication, discovery, and positioning, the MasterInformationBlockSidelink is specifically designated to carry common control information pertinent to these sidelink operations. This block is tailored for the dynamic nature of sidelink communications, where information may change with each transmission without requiring a predefined modification period or explicit change notifications, underscoring its role in efficiently managing sidelink resources and operations among UEs (User Equipment).
