Throughput drop at higher EnB transmit power #89

Hi developers,

I am curious about the throughput result from my simulation. I just tested the network with different transmit power and as I increases the tx value > 20dbm, the UE throughput started to drop as below.

At first, I thought that the distance of the UE from EnB causes this problem and I tried to fix the UE positions as below but the throughput of the UE still drop as EnB tx value increased.

I appreciate it if anyone can help with an explanation for this problem. The .ini file is as follows:

Hello,

I am not able to reproduce the chart you attached... what statistics are you observing? In any case, your network is probably saturated (because you are using only 6 RBs, and UEs are receiving heavy traffic). I am not sure the behavior of the network can be easily predicted in such situation.
