Measure SINR in LENA

[Regina Diaz]

Hi, 

I would like to add functionality to my LTE code to provide results for SINR and RSRP in the downlink and uplink. 

Could you please provide some help? 

Thanks a lot,

Regina

Hi Regina,

Do you mean that you just want to output the SINR and RSRP?  Currently LTE model in NS-3 uses CQI in eNB. You can find more information by this link: http://lena.cttc.es/manual/lte-design.html#cqi-feedback

Thanks a lot Dizhi, 

Yes, the CQI value is of interest. I would like to include this value into the MAC or RLC stats output files. Any idea how to do this?

Thanks, 

Regina

Hi Regina,

Usually I use NS_LOG_DEBUG within scheduler to get CQI values. I know this is not a standard way because it needs us to modify source codes.

I'm not sure whether we can configure the content of trace file. May be you can check the chapter seven in NS3-tutorial.

Hi Regina,

I double check the source code of MAC and RLC stats in /src/lte/helper/mac-stats-calculator.cc and /src/lte/helper/rlc-stats-calculator.cc. Then content of output file is fixed so that we cannot configure it by ourselves.

Thus, the easier way to get CQI is like what I said in last email: add NS_LOG_DEBUG in scheduler's DoSchedDlTriggerReq method. Otherwise, you need to change many codes then.
