64 QAM

[dadoba]

Does anybody have complete procedure to activate 64 QAM in the network? I mean what we have to do in Node-B, in RNC and the counters to check the performance of 64 QAM? Hardware required, etc?

Thanks

Dear Dadoba,

I hope below info helps:

Verify that the feature is included in the RBS license key:
– licenseState64Qam
Verify that the RBS 64 QAM Feature licenses is loaded in RNC:
– FAJ 121 1331, Support for 64 QAM
The following features are prerequisites in order to support64 QAM:
– Support for 16 QAM - FAJ 121 903
– Support of Enhanced layer 2 - FAJ 121 1328

For Feature Activation:The feature is activated/deactivated per RBS by the Parameter NodeBFunction:featureState64Qam

On RNC:
Hsdsch qam64Support 1

HW Requirements:
- To support peak RLC data rates over 18-19Mbps, Special Processing Boards (SPB3) are needed in RNC.

UE Requirments:
Cat 13-14 and 17-20 support both EL2 and 64QAM

Good Luck :)

Thanks!!! It will be very useful, do you know if there are some specific pm counters for this feature?

[shamim23]

You are welcome. Sorry forgot to ans this part. You may use below PM counters for 64QAM:

Number of used transport block sizes (TBS) with 64QAM (pmUsedTbs64Qam)
Number of received ACKs for a specified TBS with 64QAM (pmAck64Qam)
Number of samples with a specified CQI value (channel quality indicator) for 64QAM enabled HS-DSCHs (pmReportedCqi64Qam)

Thanks again. Lets try 64 QAM...

Tranmission should be support!

dadoba, can you please share your test result?

I have tested 64QAM in our network, it worked fine, but I have never seen speeds more than 14Mbps for a single user.

I have UE cat. 18, 64QAM rate = 100%, DTX = 0%, CQI = 30 for most of the session, no transmission or application layer limitation but...

I will appreciate if anyone can share their experience in higher speeds HSDPA.

I've tested and got around 19Mbps.somethings i want to share,
-make sure 64qam work, trnasmission support, 15 codes, UE support 21m
- SIM profile support 21M
-core network license ready for 21M
-codes available, not any other use in the test (voice or other hs)
-good rf (cqi >=28 and stable)
-use ftp, better to use ftp server in your network to avoid internet limit
