Question: In a Sidelink Logical Channel Prioritization procedure, what happens to the UE variable `SBj` (Sidelink Bucket) for a logical channel `j` when its value exceeds the sidelink bucket size?
Option 1:  `SBj` is reset to zero to allow accumulation from the start.
Option 2: `SBj` is incremented by an additional fixed value defined by RRC.
Option 3: The LCP procedure skips prioritization for logical channel `j` until `SBj` is updated.
Option 4: `SBj` is set to the sidelink bucket size (calculated as the product of sPBR and sBSD).
Explanation: According to the Logical Channel Prioritization procedure, if `SBj` exceeds the sidelink bucket size, the MAC entity sets `SBj` to the sidelink bucket size. This controls the prioritized bit rate for sidelink transmissions by preventing `SBj` from accumulating beyond the defined bucket size.
