Question: How is the Destination Layer-2 ID handled differently in Sidelink Communication versus V2X Sidelink Communication at the MAC layer?
Option 1: In both cases, it is split into two bit strings for handling at different layers.
Option 2: For Sidelink Communication, it's carried whole within the MAC header, while for V2X, it's split.
Option 3: For Sidelink Communication, the Destination Layer-2 ID is split into two parts (MSB and LSB), but for V2X Sidelink Communication, it is not split and is carried whole within the MAC header.
Option 4: The handling of Destination Layer-2 ID is dependent on the type of UE in both Sidelink and V2X Communications.
Explanation: This distinction highlights that for general sidelink communication, the Destination Layer-2 ID is divided into two parts for filtering at both physical and MAC layers, whereas in V2X sidelink communication, it remains intact and is carried within the MAC header without splitting, crucial for efficient packet filtering and delivery in these different scenarios.
