Hi everyone,
I have LTE 2100 MHz in rural area.
Daily OSS KPIs are next
Very low traffic utilization (~5% PRB)
All kind of handovers >98% SR.
RRC and ERAB est. SR > 99%.
DL and UL BLER is about 19%.
DL packet loss = 0.7%
UL packet loss = 293% (it means just 1 out of 3 packets received by eNB)
DL HARQ nack/ack ratio = 9%
UL HARQ nack/ack ratio = 76%
RRC connection reest. SR = 48%
DL mean MSC = 16
UL mean MSC = 4
Mac TA distance = <2500 meters
Our customer complains about UL performance in terms of coverage.
UL is totally dead when DL is only -110-115 dBm. Very short coverage.
There is no any features. Just 2T/2R RRU with 20W per channel and MIMO.
1st question:
Please tell based on your experience, are those KPIs are good for rural BS?
2nd question:
How can I increase UL performance:
-changing power control settings, which?
-install TMA to enhance UL?
-turn on/off DRx?
