Question: What is the scope of the Average number of active UEs on the DL per QCI measurement in an eNodeB serving one or more RNs?
Option 1: It refers to the number of active UEs connected directly to the eNodeB, including RNs.
Option 2: It refers to the number of active UEs connected directly to the eNodeB, excluding RNs.
Option 3: It refers to the total number of active UEs in the network, including those connected to other eNodeBs.
Option 4: It refers to the average number of active UEs on the uplink per QCI.
Explanation: According to the text, for an eNodeB serving one or more RNs, the measurement refers to the number of active UEs connected directly to the eNodeB, excluding RNs. This is because the measurement only considers UEs that have DTCH data queued on the downlink and are directly connected to the eNodeB.
