Question: In the context of Sidelink PRS Channel Occupancy Ratio (SL PRS-CR) for NR Physical Layer Measurements, what condition must be met regarding the relationship between 'b' and the total number of slots (a+b+1) as determined by UE implementation?
Option 1: `b` must be equal to or greater than `(a+b+1)/2`
Option 2: `b` must be less than `(a+b+1)/2`
Option 3: `b` must be exactly half of `(a+b+1)`
Option 4: There is no specified relationship between `b` and `(a+b+1)/2`
Explanation: According to the specifications for SL PRS-CR, to ensure efficient resource allocation and grant management, `b` must be less than half of the total slots (`a+b+1`). This condition is crucial for balancing resource utilization and avoiding conflicts in sidelink transmissions.
