• RF simulator

gNB and UE can be run on the same machine (?) (FK/GP)

~/openairinterface5g/cmake_targets$ ./build_oai --gNB --nrUE -w SIMU

~/openairinterface5g/cmake_targets/ran_build/build$ ln –s librfsimulator.so liboai_device.so

On one tab:

sudo RFSIMULATOR=eNB ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band78.tm1.106PRB.usrpn300.conf --parallel-config PARALLEL_SINGLE_THREAD --noS1 --nokrnmod 1

On another tab:

sudo RFSIMULATOR=127.0.0.1 ./nr-uesoftmodem --numerology 1 -r 106 -C 3510000000 -d --noS1 --nokrnmod 1

in ifconfig you should now see two new network interfaces. Try to send traffic from the gNB to the UE (using for example ping -I oaitun_enb1 10.0.0.2). Keep in mind that only downlink traffic is working.

• Phy simulator: this is mainly a run of L1 unitary tests; DL (dlsim) and UL (ulsim) are tested separately

• L1 simulator

• L2 simulator
