Hello,
In an Ericsson LTE system, when you use the PMR command to print the UL and DL throughput, the counters Int_DlThroughput_kbps and Int_UlThroughput_kbps do reflect the throughput experienced from the User Equipment (UE) perspective?
And i have noticed in some cells the Mac_throughput is higher in some cells in comparaison to Throughput, is this normal? The Mac_throughput should be higher or lower than throughput in normal situation?
Typically, when the counter indicates that it measures at the MAC layer, it almost certainly refers to the BBU or cell’s THP. This value basically refers to the average constant THP that the cell or BBU is requesting during the measurement period.
On the other hand, when the counter indicates that it measures at the RLC level, it is almost certain that it is measuring the UE’s THP. However, for this scenario, there is always a counter for the total amount of data used (usually in Kbits) and another counter for the activation/transmission time (usually in ms), since the cell or user is not consuming/transferring data all the time.
For this reason, it is common to occasionally find that the BBU/Cell’s THP may be higher than the UE’s THP. In a scenario where the cell/BBU has very low utilization, it is normal to find that the UE THP is higher, and this happens because there are many more resources available and little data transmission time, the resulting THP (of UE) is higher than that of BBU/Cell.
