SNR in Lte

[Zdeněk Tinka]

Hi all,

I'm wondering how to calculate and display SNR values in Lte network. I have one UE and one eNB in my topology. I know how to do that in WiFi but have no idea how to do that in Lte.  Have you ever solved this issue?

I will appreciate any help. Thank you very much!

There are files generated with that information 

http://www.nsnam.org/docs/models/html/lte-user.html#simulation-output

In the RSRP/SINR file, the following content is available:

1. Simulation time in seconds at which the allocation is indicated by the scheduler
2. Cell ID
3. unique UE ID (IMSI)
4. RSRP
5. Linear average over all RBs of the downlink SINR in linear units

The contents in the UE SINR file are:

1. Simulation time in seconds at which the allocation is indicated by the scheduler
2. Cell ID
3. unique UE ID (IMSI)
4. uplink SINR in linear units for the UE

Dear Konstantinos,
first of all, thank you for  your reply.

 I can see that values now. By the way, Is there any way to display that values in console when I receive packet (I'm looking for similar way of capturing packets as SnrTag in WiFi)? In future I will offload data between WiFi and LTE in dependence on SNR or SINR, so I will need to compare that values.
