🌐5G Throughput Troubleshooting

Great start to the Throughput Troubleshooting trilogy !!!

[fghedit]

Thank you so much for this video and wait for more

[the.georgest]

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.

[adebayo]

Thank you for these contents Ali, amazing!

[HK_CryptoEnthusiast]

Brilliant explanation! Thanks for sharing your knowledge 👌🏻

[ckeckponitofknowlegde]

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

[hamidrezasaberkari]

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?

[pramodsnarayan]

Is the kpi analysis and wireshark log analysis videos pending? Thanks a lot for breaking down things and making it simple. Really helps.

[jalloulbouchkara]

Hello, can you pls make Video LTE Analysis to improve Buffering time, and resolution Rate using UE log and pcap file. Thanks

[ibrahimkamhieh]

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

[awais]

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

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?

[goexpert]

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

[shantanu]

hello when is the the wireshark and KPI video coming. Waiting for a very long time.

[coolmunzir]

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

[fatimayahyaoui]

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

[m.karthikeyan]

Please, Can you give clear explanation about spectrum?
