Huawie HSDPA CQI values higher than 30

[white_Noise]

Hi gents,

As per my knowledge, the CQI value should range between 0 and 30, but in Huawei, the values are up to 35 !! Knowing that I have values in the counters for CQI values 31, 33, and 35 and zero in the 32 and 34 counters , and the max configuration we have is 3 carriers per cell..

Please support..

I hope this will usefull from Hed-ex :
The preceding counters indicate the overall distribution of the channel quality. For each Channel Quality Indicators (CQI) value, the NodeB counts the number of CQIs received in a cell during a measurement period. The CQI values range from 0 to 35. For DC-HSDPA users, the counter will be counted in anchor and supplementary carrier separately. For non-64QAM users, the values of VS.CQI.0 to VS.CQI.30 correspond to the values of CQI0 to CQI30 reported by a UE. For 64QAM users, the values of VS.CQI.0 to VS.CQI.25 correspond to the values of reported CQI0 to CQI25; the value of VS.CQI.27 corresponds to the value of reported CQI26; the value of VS.CQI.29 corresponds to the value of reported CQI27; the value of VS.CQI.31 corresponds to the value of reported CQI28; the value of VS.CQI.33 corresponds to the value of reported CQI29; the value of VS.CQI.35 corresponds to the value of reported CQI30.

Can you please let me know under which subjet in Hedex did you find this? I already searched in Hedex with no luck..

these are NodeB level counters so check corresponding lib version of the nodeb type you have, for example "BTS3900 WCDMA_V200R013..hdx"
