Question: In UTRAN's Iub interface (NBAP signalling), what is a requirement for the 'Neighbouring TDD Cell Measurement Information' IE when reporting measurements for 7.68 Mcps TDD neighbouring cells?
Option 1: Including only the Cell ID of neighbouring cells
Option 2: Including the Time Slot IE and Midamble Shift And Burst Type 3G IE if available
Option 3: Specifying the measurement duration for each reported cell
Option 4: Including the Time Slot IE and Midamble Shift And Burst Type 7.68Mcps IE if available
Explanation: This is because, when reporting on neighbouring 7.68 Mcps TDD cells for measurement purposes, providing detailed information to pinpoint the exact time and configuration used is necessary. Including the Time Slot IE and Midamble Shift And Burst Type 7.68Mcps IE (if available) ensures this specificity, as measurements can vary by time slot and midamble shift in TDD systems, crucial for accurate neighbour cell measurement analysis.
