OSI Stack Simulation Level #368

Open tayloreisman16 opened 3 years ago

tayloreisman16 commented 3 years ago

Hey guys,

I want to know what level of the OSI stack is simulated in UERANSIM. I realize that MAC addresses are not yet a part of UERANSIM; therefore, I assume that the MAC layer is not yet defined. If this is the case, how do you deal with HARQ? Does the UE communicate with the RAN via packets?

Thanks,

Taylor

Hi @tayloreisman16

Following layers are not implemented and they are simulated in UERANSIM:

how do you deal with HARQ? Does the UE communicate with the RAN via packets?

Yes, radio layer communication is simulated over UDP packets.

Best.

Hey @aligungr ,

Thanks for the reply.

I noticed that you say the RLC is not yet implemented, but the feature set says it's done? Could you clarify?

Thank you!

Yes RLC is done, but it's not currently used in the project. Because RLC protocol is somewhat meaningless without other radio layers.

Best.
