what the difference between RXQUAL measured by drive test and RXQUAL measured by KPI?17th January 2012 at 16:50 #56427pixGuest
it is the same…
the one from drive test is related only to one call, and only to the DL direction.
the KPI is an average for all calls in the cell, and is available for UL and for DL (independantly)

i have doubt in RxQual measuring in GPRS case, Actually In Packet Downlink Ack/Nack MS sends RXQUAL to BTS. i mean to say this RXQual is related to downlink only. how to calculate thr Uplink RxQual and What is the maximum threshold level for cell selection in case of RxQual.
Please give me a response.

the ul rxqual is measured by the BTS, and sent to the BSC/MFS only if NC2 is activated.
as far as i know, the RXQUAL collected statistically by the BSS are only coming from voice calls, not from packet transfers.
during drive test, you can NEVER know about the UL link (rxlev ul, rxqual ul, etc) unless you set up your OMCR so that it collect UL information for the drivetest IMSI.
this way, after the trace, you can aggregate DL measurements from the DT tool and UL measurements from the OMCR trace.

I am trying to calculate BER ,, and i have read from the internet i can get it by RXQUL as below
Number of samples with UL RQ = 1 24,558.00
Number of samples with UL RQ = 2 28,826.00
Number of samples with UL RQ = 3 32,763.00
Number of samples with UL RQ = 0 590,100.00
Number of samples with UL RQ = 4 27,853.00
Number of samples with UL RQ = 5 23,033.00
Number of samples with UL RQ = 6 7,481.00
Number of samples with UL RQ = 7 808
Number of samples with DL RQ = 0 526,009.00
Number of samples with DL RQ = 1 39,465.00
Number of samples with DL RQ = 2 44,838.00
Number of samples with DL RQ = 3 45,060.00
Number of samples with DL RQ = 4 33,749.00
Number of samples with DL RQ = 5 22,477.00
Number of samples with DL RQ = 6 16,417.00
Number of samples with DL RQ = 7 7,407.00
these data for one cell one day
how I can calculate it , and be infrom this data for TCH and SDCCH . could you explain how i get it from these daya ??25th November 2012 at 15:49 #56431pixGuest
