Question: In UTRAN's Iub interface (NBAP signalling), what additional information elements (IEs) are mandated to accompany the Neighbouring TDD Cell Measurement Information IE for 3.84Mcps TDD cells, assuming their availability?
Option 1: Time Slot IE and Midamble Shift And Burst Type IE
Option 2: Scrambling Code IE and Cell Identity IE
Option 3: UTRA Carrier IE and RNC ID IE
Option 4: Measurement Quantity IE and Reporting Trigger IE
Explanation: For accurate measurements on neighbouring 3.84Mcps TDD cells in a UTRAN environment, specifying the exact time slot (via Time Slot IE) and details about midamble configuration (via Midamble Shift And Burst Type IE) are crucial, as TDD systems rely heavily on precise timing and burst configurations for distinguishing between uplink and downlink transmissions and managing interference. Including these IEs ensures that measurements can be contextualized to specific transmission opportunities, enhancing their usefulness for network optimization and handover decisions.
