Question: What are the possible types of information that a Backhaul Adaptation Protocol (BAP) Control PDU can convey, in addition to its PDU header, in a 5G New Radio (NR) network?
Option 1: Only BH RLF (Radio Link Failure) related indications and flow control polling.
Option 2: Flow control feedback per BH RLC channel, flow control feedback per BAP routing ID, flow control polling, and BH RLF related indication.
Option 3: Exclusive BH RLC channel configurations and BAP routing ID updates.
Option 4: Solely network congestion notifications and QoS (Quality of Service) policy updates.
Explanation: In the context of 5G NR networks, BAP Control PDUs play a crucial role in managing backhaul efficiently. The correct answer reflects the versatility of BAP Control PDUs in handling various types of information crucial for effective network operation, including feedback mechanisms (flow control per BH RLC channel and per BAP routing ID), proactive measures (flow control polling), and failure notifications (BH RLF related indications). This comprehensive approach ensures robust backhaul adaptation.
