Question: What is the purpose of the "UL Total PRB Usage" measurement in E-UTRAN?
Option 1: To measure the total usage of physical resource blocks (PRBs) on the uplink for all traffic, including transmissions to/from RNs and UEs directly connected to the eNodeB.
Option 2: To measure the total usage of PRBs on the downlink for packet switched traffic in EPS.
Option 3: To measure the signal strength of the uplink transmission from RNs to the eNodeB.
Option 4: To measure the throughput of the uplink transmission from UEs to the eNodeB.
Explanation: The "UL Total PRB Usage" measurement is used to determine the total usage of physical resource blocks (PRBs) on the uplink for any purpose, including transmissions to/from RNs and UEs directly connected to the eNodeB. This measurement provides valuable insights into the utilization of uplink resources in E-UTRAN networks.
