Question: In UTRAN Iur interface RNSAP signalling, what is a requirement for the 'Neighbouring TDD Cell Measurement Information' IE when measurements can be performed on every time slot and midamble shift?
Option 1: Including only the Cell ID of neighbouring cells
Option 2: Including just the Time slot LCR IE or Midamble shift LCR IE, whichever is available first
Option 3: Including both Time slot LCR IE and Midamble shift LCR IE if available
Option 4: Excluding all LCR IEs for TDD neighbouring cells to reduce signalling overhead
Explanation: This option is correct because the question specifies that measurements can be performed on every time slot and midamble shift. Including both Time slot LCR IE and Midamble shift LCR IE (if available) ensures comprehensive reporting for effective measurement and potential handover or network optimization decisions in UTRAN networks, aligning with efficient use of signalling for neighbour cell measurements in TDD mode.
