Throughput Troubleshooting: Drive Test Analysis
In this session, we will discuss about practical throughput troubleshooting using Drive Test logs to root-cause various issues including Coverage or Interference problems, congestion or capacity bottlenecks and transport or backhaul anomalies.

More to come! Thanks!

@the.georgest 2 года назад

Good stuff. I would say that one scenario is missed for the E2E issues, when there is a correlation of low TTI utilization and low PRB utilization. This is maybe even more observed scenario when transport/core issue occurs, as it is rather expected that e/gNB will not have enough data in buffer to fully utilize both frequency and time dimensions.

@OurTechPlanet 2 года назад

Yes that can be a scenario as well. But it should still be triggered in the Scenario-4 explained in the video :)

Hi, Thanks for the great video. Just out of curiosity would you please let me know when you will release the second and third videos for throughput analysis via KPI and Wireshark?

@OurTechPlanet Год назад

Yes, we are working on them but might take a month or so :)

@ckeckponitofknowlegde1543 Год назад

Great explanation. Thanks a lot. Could you please help with 5G not showing during data testing ?

@OurTechPlanet Год назад

Usually, it would mean that 5G coverage is not there but detailed investigation of the issue would need drive test and signaling traces

There is one of the concern of IBS site 20 Mhz bandwidth L18 sector having low thp at one sector having RB usage around 80-90 fluctuating and DL grant 100 around Is it related to Transmission issue or RRU issue , for low scheduling cause low THP? However other sector having same bandwidth and having good Dl grants around 800 , with good THP

@OurTechPlanet 2 года назад

If there are two sectors with the same backhaul and one is working fine then it should not be a backhaul issue. It should be something sector specific like RRU as you mentioned

Hi, What is the difference between SSV drive test and SST drive test? SST drive test stands for what?

@OurTechPlanet Год назад

I think SSV is Single Site Verification and SST is Single Site Testing. Might be same things

@berkinsevim5539 2 года назад

LTE_UE_RB_Num_DL This attribute gives the average number of resource blocks the UE was allocated in the downlink over the sampling period. The attribute is calculated only considering the downlink transmission time intervals for which the UE received PDSCH data (TBs with RNTI-Type as C-RNTI) . This is Actix Definition ...High RB Num_DL means that the cell is congested ? or the cell can assign lots of RB due to less traffic? How can we see this?

@OurTechPlanet 2 года назад

If the UE is getting high number of RBs then it means there is no congestion. But if the UE is getting fluctuating RB assignments then that can indicate congestion.

@coolmunzir 2 года назад

I use Actix usually... can you provide exact name of the Frame Usage parameter in Actix

@OurTechPlanet 2 года назад

As far as I remember, it was frame usage. You can search for "frame" and see if that gives you any hits.

@go4expert888 2 года назад

Great explanation! I have scenario related to what you explained. I have scenario with TDD pattern DDDSU , 100mhz bandwidth(ul/dl bwp 273rbs configured on du) , mcs 27 , sinr 30+ , rsrp is -65 , rbs given to uE is 48 rbs , grants given to uE 1100-1200. I see DL throughput on uE 30mbps and thats very very very low! On CU pdcp log I see it recieves 500mbps from the core (the amount that I pumped from the core is 500mbps) and CU gives DU only 30mbps and thats weird!!! What could be the bottleneck in my case? like du is fine and rf condition is fine and core also gives the CU the required pumped data..but CU gives DU only 30mbps!! A pleasure for your feedback/suggestion

@OurTechPlanet 2 года назад

If you have high grant count and low RBs, then it can be congestion. But if you are consistently getting very low RB count and there is no congestion then it can be related to some bwp configuration

@go4expert888 2 года назад

@@OurTechPlanet Im getting constantly rbs given to uE 48rbs and grants 1100-1200 grant constantly ; on du configuration bwp in ul/dl configured 273rbs (rf condition is very good sinr 45). But noticed that CU only gives du 30mbps although CU recieved from core 500mbps but gives to du only 30mbps. So any suggestion please about what could be the issue?

@go4expert888 2 года назад

@@OurTechPlanet what Im confused at is why CU only gives DU 30mbps although CU got 500mbps in its pdcp data

@fatimayahyaoui2355 Год назад

Hi , plz I Have a qst if we have very low frame usage in DL so issue in backhaul or transport , but in my case I don't have problm in DL Packet loss ( OSS) , so how can we investiguat ? and there is another Kpi to check by OSS or in DT to confirm this problem (transport issue)? thxs a lot

@OurTechPlanet Год назад

If you have low frame usage in DL Drive Test and no packet loss, it should still indicate a higher layer issue in most of the cases.
