Question: In FR1, when a UE measures CSI-RS for Beam Failure Detection (BFD) with a different Sub-Carrier Spacing (SCS) than an SSB for RLM/BFD/CBD/L1-RSRP within the active BWP, what is the UE's measurement capability if it does not support simultaneousRxDataSSB-DiffNumerology?
Option 1: The UE can perform CSI-RS measurement without any restrictions.
Option 2: The UE measures both CSI-RS for BFD and SSB simultaneously with reduced accuracy.
Option 3: The UE is required to measure one of, but not both, CSI-RS for BFD measurement and SSB, expecting a longer measurement period.
Option 4: The UE skips CSI-RS measurement for BFD when SSB is detected in the same BWP.
Explanation: According to specifications for FR1 scenarios, if the UE does not support simultaneous reception of data and SSB with different numerologies, it cannot measure both CSI-RS for Beam Failure Detection and an SSB with a different SCS within the active BWP simultaneously. Therefore, the UE has to choose between measuring one or the other, resulting in a longer measurement period for CSI-RS based BFD measurement.
