What would cause a high level of downlink BLER vs uplink BLER? Obviously uplink BLER would be something pointing at the tower, but what would cause the BLER towards the stations? Would another LTE site operating on the same frequency show up as downlink BLER?
I’m looking at some of my subscriber units on a specifically loaded eNB and some of them have 14-15% BLER on the downlink.
Where do you measure the BLER Matt?
It’s a measurement unit in the most recent eNB beta.
Thanks for that info Matt. BLER measurements are progress!
It is standard with Tier one suppliers… In my experience with Alcatel -Lucent LTE (now Nokia) DL BLER was mostly due to interference and also where coverage was weak at cell edges for example… (low MCS values and higher BLER)
Would another LTE site operating on the same frequency show up as downlink BLER?
if they are not GPS synchronized and if your X2 communication between the eNbs is not working, then yes for sure I say…
