Severe Congestion causes Packet Drops and Packet Delay. Light Congestion causes a decrease in throughput. Generally Congestion is handled in the end to end by protocols like TCP which has a mechanism to handle congestion when it detects congestion en-route.,

User experience will not be same as before in case of congestion. This is wholesome of several KPIs affected at different NEs depending on point and nature of congestion in network. For example user plane congestion should be visible on eNB/S/PGW. For every type of service provisioned through established bearer, congestion will impact differently. Slow browsing, low download speeds are most reported issues in such cases. While any realtime (delay sensitive apps e.g. voice, video) shall face lags/drops and similar behavior.

I don't know the complete use of CQI at eNodeB. Does it impact only downlink scheduling parameters or also considered while granting uplink resources ?

In an effort to improve User End Throughput, we decided to increase the available power within LTE 800Mhz cells from 20W to 40W.

The power increase on the L800 cells involved removing the existing 3dB attenuation and also modifying the power of the reference signal per resource grid, such that we simply maintained the same cell radius whilst increasing the available power inside it from 20W to 40W.

The results from the trial haven't been as favourable as we hoped it would be, the increase in the User End Throughput was between 5-10%, while small improvements were also seen with CQI and PDSCH but overall the improvements have been disappointing.

Has anyone carried out similar changes in the past and if so what type of increase in the User End Throughput was observed. Also if anyone has any helpful documentation that compares User Throughput against Power Increase that would also be very helpful. We have arrived at a bit of dead end with this one so any feedback would be gratefully appreciated.
