High Packet loss in DL & UL QCI-1_Huawei

Hi Experts,

I am getting High Packet loss Rate in QCI-1 for both UL & DL in Volte KPI.
What can be the reasons & how it can be rectified.

  • Link Congestion
  • Bad Coverage / Quality
  • Transmission
  • Hardware
    • Cpri cable
    • VSWR, RSSI
      • Ethernet Cable connection

PDB timer value?

High overlapping or threshold set wrong for qci1 dl/ul bler leading to packet discard at high rate.
Can check tdiscard timer.

Sinr in DL/UL main culprit for high packet loss, considering TX end no issue for packet loss.
