LTE KPI test procedure : DL User Throughput

1.1.1      DL User Throughput (Ave.)

Name:  DL User Throughput (Ave.)
Purpose:  To verify that a UE is supported average download throughput
Measurement method	During driving the Cell coverage, Measure Download Traffic rate using FTP
Acceptable range	More than 15Mbps.

1.1.1.1      Test conditions and requirements

Ÿ A laptop computer to monitor the UE and DM tool for UE.

Ÿ Test route shall be predetermined in the test network.

Ÿ Network shall be designed to support minimum data rates of 1 Mbps DL and 256 kbps UL.

Ÿ There is no throughput limit on the FTP server.

Ÿ System configuration is set to #2 UL - DL Configuration and #7 Special_subframe_configuration.

Ÿ UE and PC are supported maximum throughput. (no limit)

1.1.1.2      Test procedure

1.     Locate the UE at a predefined place.

2.     The test point should be over the cell edge RF conditions. (RSRP: higher than -100dBm)

3.     Connect the UE to eNB. (Initial attachment)

4.     Run FTP client at the laptop and Connect to the FTP server.

5.     Start to download traffic.

6.     Drive the vehicle to the predefined route within the cell.

7.     Measure the average data rate during the test by DM or other tool.

8.     Report the results.

1.1.1.3      Pass/Fail criteria

Ÿ The DL average UE throughput shall be higher than acceptable range.

1.1.2      UL User Throughput (Ave.)

Name: UL User Throughput (Ave.)
Purpose: To verify that a UE is supported average upload throughput
Measurement method	During driving the Cell coverage, Measure upload Traffic rate using FTP
