The power estimation of the UE has to be debugged (calibrated?). In the meantime, using "--ue-rxgain 140" lets the UE and eNB talk to each other in the basic simulator.

The driver tcp_bridge_oai.c is to be used with the basic simulator.
|
|
|
|
To build the basic simulator:
|
|
cd [openair top directory]
|
|
. oaienv
|
|
cd cmake_targets
|
|
./build_oai -I -w USRP
|
|
./build_oai --basic-simulator
|
|
cd ../common/utils/T/tracer
|
|
make
|
|
|
|
To use it, you need to run the eNB and the UE.
|
|
|
|
The eNB requires the T tracer.
|
|
Open two terminals.
|
|
In one terminal, run:
|
|
cd [openair top directory]
|
|
cd common/utils/T/tracer
|
|
./enb -d ../T_messages.txt
|
|
In the other terminal, run:
|
|
cd [openair top directory]
|
|
cd cmake_targets/basic_simulator/enb
|
|
export ENODEB=1
|
|
sudo -E ./lte-softmodem -O [configuration file] --T_stdout 0
|
|
[configuration file] is just a regular configuration file.
|
|
The eNB needs an EPC.
|
|
|
|
To run the UE, open a terminal and run:
|
|
cd [openair top directory]
|
|
cd cmake_targets/basic_simulator/ue
|
|
sudo ./lte-uesoftmodem -C 2680000000 -r 25 --ue-rxgain 140
|
|
Adapt the value of -r, it has to match the value N_RB_DL in the configuration
|
|
file of the eNB. (Same for -C which should match the value downlink_frequency
|
|
in the configuration file.)
|
|
|
|
The UE configuration (security keys) is generated from the file
|
|
openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf. You need to configure
|
|
your EPC to know about the UE. If you change the file
|
|
openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf then you need to
|
|
regenerate the configuration files using the program targets/bin/conf2uedata.
|
|
You run it as:
|
|
$OPENAIR_DIR/targets/bin/conf2uedata -c $OPENAIR_DIR/openair3/NAS/TOOLS/ue_eurecom_test_sfr.conf -o $OPENAIR_DIR/cmake_targets/basic_simulator/ue
