1      Test ITEMS

1.1    Throughput

1.1.1      DL Cell Throughput (Max.)

Name:  DL Cell Throughput (Max.)
Purpose:  To verify that a cell is supported maximum download throughput
Measurement method	FTP is used, peak sector DL data rate shall be more than 0.95 x acceptable range
Acceptable range	More than 90Mbps.

1.1.1.1      Test conditions and requirements

Ÿ Two laptop computers to monitor the two UEs and two DM tools.

Ÿ A location for test condition (Cell Near link condition) shall be predetermined in the single Cell environment.

Ÿ There is no throughput limit on the FTP server and backhaul.

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

Ÿ UEs and PCs are supported maximum throughput. (no limit)

Ÿ If FTP is used, peak sector DL data rate shall be higher than 0.95 x acceptable ranges.

1.1.1.2      Test procedure

1.      Locate the test UEs at a predefined place with near link condition in the single Cell environment.

2.      The test point should be over the cell RF conditions. (RSRP: higher than -70dBm, SNR: higher than 30).

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

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

5.      Each UEs, start to download traffic with 5 FTP sessions.

6.      Measure the average data rate for 1 minute by DM or other tool and report the results.

1.1.1.3      Pass/Fail criteria

Ÿ The DL maximum cell throughput shall be higher than acceptable range.

1.1.2      UL Cell Throughput (Max.)

Name: UL Cell Throughput (Max.)
Purpose: To verify that a cell is supported maximum upload throughput
Measurement method	FTP is used, peak sector DL data rate shall be more than 0.95 x acceptable range
Acceptable range	More than 6.1Mbps.

1.1.2.1      Test conditions and requirements

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

Ÿ A location for test condition (Cell Near link condition) shall be predetermined in the single Cell environment.

Ÿ There is no throughput limit on the FTP server and backhaul.

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)

Ÿ If FTP is used, peak sector DL data rate shall be higher than 0.95 x acceptable ranges.

1.1.2.2      Test procedure

1.     Locate the test UE at a predefined place with near link condition in the single Cell environment.

2.      The test point should be over the cell RF conditions. (RSRP: higher than -70dBm, SNR: higher than 30).

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

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

5.      Start to upload traffic with 1 FTP session.

6.      Measure the average data rate for 1 minute by DM or other tool and report the results.

1.1.2.3      Pass/Fail criteria

Ÿ The UL maximum cell throughput shall be higher than acceptable range.
