in the following file : https://gitlab.com/cttc-lena/nr/-/blob/master/examples/cttc-nr-multi-flow-qos-sched.cc?ref_type=heads

I found this part of code where they use EPS Bearer:

"nrHelper->ActivateDedicatedEpsBearer(ueDevice, ue2flowsDcGbrBearer, ue2FlowsDcGbrRule);"

"// The bearer that will carry UE with 1 flow Non GBR traffic NrEpsBearer ue1flowBearer(NrEpsBearer::NGBR_LOW_LAT_EMBB);"

"// The bearer that will carry UE with 2 Flows Non GBR traffic NrEpsBearer ue2flowsNgbrBearer(NrEpsBearer::NGBR_LOW_LAT_EMBB); // qosInfoInterServ2);"

"// Activate a dedicated bearer for the traffic type nrHelper->ActivateDedicatedEpsBearer(ueDevice, ue1flowBearer, ue1flowRule);"


"// Activate a dedicated bearer for the traffic type nrHelper->ActivateDedicatedEpsBearer(ueDevice, ue2flowsDcGbrBearer, ue2FlowsDcGbrRule);"
And I fear that the code is only suitable for 4G networks.

Thank you in advance

I am working on revisions to better align the transport channel and QoS architecture with 5G.  People interested in this can review and comment on this here:  https://gitlab.com/cttc-lena/nr/-/merge_requests/320

The 5G LENA framework still uses a 4G core model and terminology, but this part should be gradually upgraded.
