Question: What is the condition for MAC to consider logical channels when multiplexing and assembling PDU(s) associated with one SCI?
Option 1: Logical channels with the same Destination Layer-2 ID
Option 2: Logical channels with the same Source Layer-2 ID
Option 3: Logical channels with different Source Layer-2 ID-Destination Layer-2 ID pairs
Option 4: Logical channels with the same Source Layer-2 ID-Destination Layer-2 ID pair
Explanation: According to the MAC protocol specification, when multiplexing and assembling PDU(s) associated with one SCI, the MAC considers only logical channels with the same Source Layer-2 ID-Destination Layer-2 ID pair. This ensures that packets are transmitted correctly and efficiently in V2X sidelink communication scenarios.
