Question: What is the scope of uniqueness for a Priority Queue ID in relation to MAC-d flows as per RNSAP signalling?
Option 1: Unique only within a specific MAC-d flow for a UE Context
Option 2: Unique across all MAC-d flows for multiple UE Contexts within a cell
Option 3: Unique across all Common MAC flows but not necessarily across all MAC-d flows for one UE Context
Option 4: Unique across all MAC-d flows that are currently allocated for one UE Context or across all Common MAC flows within a cell
Explanation: The correct answer reflects the precise scope of uniqueness as defined by RNSAP signalling standards, ensuring efficient management and differentiation of Priority Queues both at the individual UE Context level (across its allocated MAC-d flows) and collectively within a cell's Common MAC flows. Options 1 through 3 either narrow or broaden this scope incorrectly, potentially leading to misunderstandings in queue management uniqueness.
