Question: What happens when the actual transport BCH blocks required for a System Information Block (SIB) are less than the scheduled SEG_COUNT in a 3GPP-conformant User Equipment (UE) scenario?
Option 1: The SIB repetition period (SIB_REP) is adjusted to accommodate the reduced number of transport BCH blocks.
Option 2: Error correction mechanisms are triggered to fill the unused transport BCH blocks.
Option 3: No_segment blocks are placed in the remaining scheduled transport BCH blocks, and the SEG_COUNT IE value is updated accordingly.
Option 4: The excess scheduled transport BCH blocks are reallocated for other SIB transmissions.
Explanation: This is because, as per the 3GPP conformance testing specifications, when the actual transport BCH blocks needed for a SIB are fewer than scheduled (SEG_COUNT), the unused slots must be filled with no_segment blocks to maintain the SIB repetition period (SIB_REP) constant across different test scenarios. Additionally, the SEG_COUNT Information Element (IE) value in the Master Information Block (MIB) or System Broadcast 1 (SB1) is updated to reflect the actual number of transport BCH blocks used, ensuring efficient resource utilization and accurate system configuration.
