14. Part 2 How to get the advanced information from MMT trace

15. 2.1 Enable/display the advanced information Set “Capture Filter Switch” and “Display Filter Switch” to OFF as below for enabling/displaying the advanced information. The above setting should be applied after staring scenario, because of the setting will be neglected, if set it before starting scenario. confidential MCB-1QST11067

16. 2.2 Use the Trace log conversion program to create the CSV file format. The Trace log conversion program converts the measurement result for the physical channel in the Trace log file saved in binary format to CSV files format as below. Drag and drop the saved trace log file onto the shortcut Trace Converter in C:\MX843010\Trace.. confidential MCB-1QST11067

17. 2.3 Get the advanced information from the created CSV files The following CSV files will be created by conversion program. The almost advanced information are included in the Downlink/ Uplink Report information file. Refer to the “Control Software Operation Guide” to get the detailed explanation.Control Software Operation Guide “ MD8430A Easy-to-understand Signalling Tester (Control Software Operation Guide)” - Offline Measurement Using Trace Log section confidential MCB-1QST11067

19. Part 3 Practice

20. 3.Practice UE eNB DCI & DL Message SR UL grant HARQ-ACK UL Message HARQ-ACK How to get DCI ? How to get UL HARQ Feedback ? How to get SR? How to get UL grant ? How to get DL HARQ Feedback (HI)? Generally, We only can catch some limited information from MMT trace. However, that is not enough for us to debug or further confirm eNB/UE behavior, So, We should get more information like DCI, UCI and so on. That is not enough ! confidential MCB-1QST11067

21. 3.1 How to get DCI Open the “ ” file and find DCI according [SFN, Subframe] and [Progress Time] as below. Get [SFN, Subframe] and [Progress Time] of target from trace. -Apply the excel filtering at the 1st row of data. -Set the “System Frame Number” column to “363”, “Sub Frame Number” column to “1”. -Determine the row by “24.1”, if multiple rows have been filtered. -Find the DCI information at “DCI ” column. UEeNB DCI & DL Message confidential MCB-1QST11067

22. 3.2 How to get UL HARQ Feedback Get [SFN, Subframe] and [Progress Time] of target from trace. Calculate Timing of the UL HARQ Feedback by [SFN, Subframe] as below. -FDD [SFN, Subframe] + 4 subframe -TDD [SFN, Subframe] + x subframe, x is depend on TDD UL-DL configuration (Refer to TS.36.213 -7.3) -Apply the excel filtering at the 1st row of data. -Set the “System Frame Number of UCI ” column to “363” the “Sub Frame Number of UCI ” column to “1+4 = 5 ”. -Determine the row by “24.1”, if multiple rows have been filtered. -Find UL HARQ Feedback at the “HARQ-AN of Received value of DCI ” column. UEeNB DCI & DL Message ACK confidential MCB-1QST11067 Open the “ ” file and find DCI according calculated values and [Progress Time] as below.

23. Open the “ ” file and find DCI according [SFN] and [Progress Time] as below. 3.3 How to get SR Get [SFN] and [Progress Time] of target from trace. -Apply the excel filtering at the 1st row of data. - Set the “System Frame Number of UCI ” column to the value less than or equal to “366” -Determine the row by “24.1”, if multiple rows have been filtered. -Set “1” at “SR of Received value of DCI ” column.
