I think it came from interference case that make UL bad with high level value:
Service affect:
- Data drop rate
- Call drop rate
- E-RAB Setup success rate
- Increase voice DL&UL silent

If talking about transmission part it made ping delay from source to destination

Thanks!

The main reasons for the degradation of a data channel and the corresponding bit error rate, BER is noise and changes to the propagation path (where radio signal paths are used). Both effects have a random element to them, the noise following a Gaussian probability function while the propagation model follows a Rayleigh model. This means that analysis of the channel characteristics are normally undertaken using statistical analysis techniques.

For fibre optic systems, bit errors mainly result from imperfections in the components used to make the link. These include the optical driver, receiver, connectors and the fibre itself. Bit errors may also be introduced as a result of optical dispersion and attenuation that may be present. Also noise may be introduced in the optical receiver itself. Typically these may be photodiodes and amplifiers which need to respond to very small changes and as a result there may be high noise levels present.

Another contributory factor for bit errors is any phase jitter that may be present in the system as this can alter the sampling of the data.
