Question: In UTRAN's Iub interface Node B Application Part (NBAP) signalling, what is a requirement for the Neighbouring TDD Cell Measurement Information Element (IE) when measurements can be performed on every time slot and midamble shift?
Option 1: Including only the Time Slot LCR IE if midamble shift data is unavailable.
Option 2: Including both Time Slot LCR IE and Midamble Shift LCR IE if available.
Option 3: Excluding both Time Slot LCR IE and Midamble Shift LCR IE for TDD cells.
Option 4: Replacing Time Slot LCR IE with a Cell ID for neighbouring cells.
Explanation: This is because the Neighbouring TDD Cell Measurement Information Element (IE) aims to provide comprehensive measurement data. Since measurements can be performed on every time slot and midamble shift, including both relevant IEs (Time Slot LCR IE and Midamble Shift LCR IE) when available ensures that the measurement information is as detailed and useful as possible for neighbouring 1.28Mcps TDD cells in UTRAN's NBAP signalling context.
