Question: In a 5G network, what does the 'Average value of scheduled MIMO layers per PRB on the DL' measurement primarily indicate about a cell's downlink (DL) performance within a given measurement period?
Option 1: The total number of PRBs allocated for transmission in the cell.
Option 2: The average throughput achieved per user equipment (UE) in the cell.
Option 3: The average multiplexing efficiency of MIMO layers across used PRBs in the cell, reflecting its capacity utilization for packet switched traffic.
Option 4: The percentage of spare PRBs available for potential new transmissions within the cell.
Explanation: This measurement provides insights into how efficiently a cell utilizes its resources (PRBs) for MIMO scenarios on the downlink by averaging the number of MIMO layers scheduled per PRB, relating to the cell's capacity utilization for packet switched traffic.
