Question: For a UE (User Equipment) in RRC_IDLE state, utilizing an SCS (Subcarrier Spacing) of 370.37 Hz numerology, how is the MBSFN (Multicast-Broadcast Single Frequency Network) RSRQ (Reference Signal Received Quality) measurement period defined?
Option 1: Fixed at 640 ms for all UEs in RRC_IDLE.
Option 2: As the time to decode 3 subframes containing PMCH (Physical Multicast Channel) transmissions, with a minimum of 320 ms.
Option 3: Based on the UE's DRX (Discontinuous Reception) cycle length, plus an additional 100 ms buffer.
Option 4: As the maximum of 640 ms or the period to decode 5 symbols containing PMCH transmissions.
Explanation: This answer reflects the exception defined for a 370.37 Hz SCS numerology, where the MBSFN RSRQ measurement period is based on decoding symbols rather than subframes, ensuring adherence to the standard's requirements for measurement accuracy and reporting.
