Question: What is the primary purpose of measuring 'UL PRB Usage per SSB' in a 5G NR cell, and how is this measurement optionally further categorized?
Option 1: To evaluate downlink signal strength, split by QoS resource type for voice services only.
Option 2: To assess uplink physical resource block usage as a percentage per SSB beam, optionally divided into subcounters based on Non-GBR, GBR, and Delay-critical GBR QoS resource types.
Option 3: To monitor the total number of PRBs available in the cell, without any optional subdivisions by QoS type.
Option 4: To gauge the impact of beamforming on uplink data speeds for a single QoS resource type.
Explanation: The correct answer accurately reflects the primary purpose of measuring 'UL PRB Usage per SSB' as evaluating uplink physical resource block usage percentage per SSB beam, with optional subdivision into Non-GBR, GBR, and Delay-critical GBR QoS resource types, crucial for effective radio resource management in 5G networks.
