5G-LENA is distributed separately from upstream ns-3.

You can find it here: https://gitlab.com/cttc-lena/nr/

For a beamforming scenario example, see examples/cttc-realistic-beamforming.cc or examples/rem-beam-example.cc

Thank you for previous response, actually i said that i want to simulate beamforming so i have installed that nr module in contrib directory of ns3 i am currently using and tried to run 2 examples, i am getting error shown below , actually i am working in ns-o-ran so i have configured ns3 in that way given in this https://openrangym.com/tutorials/ns-o-ran and the repository i am currently using is https://github.com/wineslab/ns-o-ran-ns3-mmwave.

Is there anything more needed to configure??

You're doing a lot of weird stuff.
First is using Waf.
Second is mixing nr and mmwave, which are different things.
Third is copying examples to the scratch directory and hoping that it will work without the rest of the module.

actually ns-o-ran is using ns3 v3.6 , at that time waf was the primary command used to build and configure , that's why i am using waf instead of ns3 , and since 5g supports mmwave that's why i cloned mmwave module as documented in OpenRAN GYM https://openrangym.com/tutorials/ns-o-ran and please tell me whether i have to add other module in ns3 src directory to work with it , actually i have downloaded nr version 2.1 which is compatible with ns3 version 3.6 as documented in gitlab nr repository , how i should proceed further , can you help me out?

Hi, @Gabriel , Can you please tell me how can i use NR module along with ns-o-ran , it will be helpful for me.

You don't. ns-o-ran requires a specific version of mmwave which implements the E2 termination at the gNB. NR currently doesn't have those.

Thank you for your response , Is it feasible to impliment beamforming in ns3 with the help of mmwave module.
