get UserControlInfo at the application layer

[gehirndienst]

Hello,

I model a learning environment for UDP data transmission between dynamic UEs and a static server. I would like to be able to know the channel information at the application layer, i.e., inside my UDP app. As far as I could get, the only broadcasted statistics so far are CQI and SINR signals from LtePhyand LteNicmodules. However, to compute e.g., SINR in LteRealisticChannelModel, one needs to pass an LteAirFrame and UserControlInfo as parameters, which are obtained in handleAirFrame methods from LtePhy* modules via getting the LteAirFrame tag.

Unfortunately, as one can see, this UserControlInfo object exists only within the scope of ::handleAirFrame and is published only in a form of CQI signal. I wonder if there is a way to get this object or at least its fields somehow without extending LtePhyUe module? Thanks!

Best Nikita

Hello,

if I understand your problem, I think one option could be able to emit the whole object as a signal, like you do with statistics. For example, you could declare a new signal in the NED file, and emit the object (with the emit() function) in the handleAirFrame() function using that signal. In the application, you could listen to the signal and catch it when it is emitted. Please refer to the OMNeT++ manual for more information: https://doc.omnetpp.org/omnetpp/manual/#sec:simple-modules:signals
