Question: For a UE performing measurements on a neighbor cell served by a different satellite in LEO, which of the following statements is true regarding its scheduling availability when `deriveSSB_IndexFromCell` is enabled?
Option 1: The UE can transmit PUCCH/PUSCH/SRS on all symbols within the SMTC window duration, except for SSB symbols to be measured.
Option 2: The UE cannot transmit or receive any signals (PUCCH/PUSCH/SRS/PDCCH/PDSCH/TRS/CSI-RS) for the entire duration of the SMTC window.
Option 3: The restriction on transmitting PUCCH/PUSCH/SRS or receiving PDCCH/PDSCH/TRS/CSI-RS applies only to SSB symbols, without any additional symbol restrictions.
Option 4: The UE is not expected to transmit PUCCH/PUSCH/SRS or receive PDCCH/PDSCH/TRS/CSI-RS on SSB symbols to be measured, plus an additional data symbol before and after each consecutive SSB symbol within the SMTC window duration.
Explanation: When `deriveSSB_IndexFromCell` is enabled for a UE measuring a neighbor cell served by a different LEO satellite, the UE's scheduling availability is restricted to prevent interference during measurements. Specifically, the restriction applies not just to the SSB symbols themselves but also to the data symbols immediately preceding and following each consecutive SSB symbol within the SMTC window duration, ensuring accurate measurements by minimizing potential signal contamination.
