OAI RAN
danger
This page shows how to modify the configuration file to adapt the parameters to each network. The OAI configuration file is constantly evolving and some parameters can change name, be replaced or deleted.
tip
For all the examples, follow the inline comments for explanations.
Configuration Sources
Usually OAI CI/CD team share the current configuration files in openairinterface5g/ci-scripts/conf_files/
On the other hand the folder openairinterface5g/targets/PROJECTS/GENERIC-NR-5GC/CONF/ is maintained by a
responsible for testing the high throughput, so it is another reliable source of useful configuration files.
Given an up-to-date configuration file the following sections explain how to adapt it to your specific case.
Network Parameters
Cell configuration
tracking_area_code = 1; # make sure it matches the TAC specified in the CN
plmn_list = (
{
mcc = 505; # make sure it matches the MCC specified in the CN
mnc = 01; # make sure it matches the MNC specified in the CN
mnc_length = 2; # MNC digit length
snssaiList = (
{
# This section allows to specify the available network slices
sst = 1; # Value specific to Quectel in Row Commercial mode
sd = 0x000000; # Value specific to Quectel in Row Commercial mode
}
);
}
);
danger
There is no guarantee that other SST values would work.
Interfaces
AMF parameters:
amf_ip_address = (
{
ipv4 = "127.5.2.2"; # AMF interface IP address used for the NGAP. Syntax: do not specify the network mask (e.g. /24)

active = "yes";
preference = "ipv4";
}
);
NETWORK_INTERFACES :
{
# In this section it is required to specify the interface name and IP address use by the gNB to communicate with the AMF.
# In this specific case the AMF is located in the same machine as the gNB this is why the addresses are in local host.
# In case the AMF resides in a different host of your LAN use the appropriate network interface
GNB_INTERFACE_NAME_FOR_NG_AMF = "lo"; # interface name
GNB_IPV4_ADDRESS_FOR_NG_AMF = "127.5.2.130/24"; # syntax specify the Network mask (e.g. /24)

};
caution
For the case CU-DU the networking parameters are specific. Check the dedicated section
Radio Parameters
OAI does not yet support a different number of antennas in DL/UL. For example, MIMO 2x2 OK MIMO 2x1 not. List of parameters to be modified to vary the MIMO capabilities

Specific Parameters per RU/split
For each specific use case there are some parameters that need to present in the configuration file.
B210
RUs = (
{
local_rf = "yes" # indicates the monolithic connection to the SDR
nb_tx = 1 # SISO #2;MIMO
nb_rx = 1 # SISO #2;MIMO
att_tx = 6; # ranges 6-10 if the UE is close to the B210 antennas. Leave 0 otherwise
att_rx = 6; # ranges 6-10 if the UE is close to the B210 antennas. Leave 0 otherwise
bands = [78];
max_pdschReferenceSignalPower = -27; # recommended value
max_rxgain = 114; # recommended value
eNB_instances = [0];
sdr_addrs = "type=b200"; # if both B210 and N300 connected to the same server allows to pick up the good board
#beamforming 1x4 matrix:
bf_weights = [0x00007fff, 0x0000, 0x0000, 0x0000];
clock_src = "internal"; # recommended value if any sync source attached to the B210
}
);
N300
RUs = (
{
local_rf = "yes" # indicates the monolithic connection to the SDR
nb_tx = 1; # SISO #2;MIMO
nb_rx = 1; # SISO #2;MIMO
att_tx = 10; # ranges 6-10 if the UE is close to the B210 antennas. Leave 0
att_rx = 10; # ranges 6-10 if the UE is close to the B210 antennas. Leave 0
bands = [78];
max_pdschReferenceSignalPower = -27; # recommended value
max_rxgain = 85; # recommended value
eNB_instances = [0];
##beamforming 1x2 matrix: 1 layer x 2 antennas
bf_weights = [0x00007fff, 0x0000];
# N300 specific parameters. use in a terminal uhd_find_devices to discover yours
sdr_addrs = "type=n3xx,mgmt_addr=192.168.20.2,addr=192.168.10.2,second_addr=192.168.20.2,clock_source=internal,time_source=internal"
}
);
AW2S
RUs = (
{
local_if_name = "ens1f1"; # eth interface name to dialog with the AW2S
remote_address = "192.168.100.50"; # ip address of the AW2S RRH
local_address = "192.168.100.1"; # ip address of your server eth interface
local_portc = 50000;
remote_portc = 55444;
local_portd = 52001;
remote_portd = 52183;
local_rf = "no" # not monolithic. No local rf but we have split to connect to the RRH
tr_preference = "udp_ecpri_if5" # use transport preference eCPRI for the split
num_tp_cores = 4; #see below
rxfh_core_id = 3; #see below
txfh_core_id = 2; #see below
tp_cores = [8,9,10,7]; #see below
nb_tx = 2 # 1 SISO; 2 or 4 MIMO
nb_rx = 2 # 1 SISO; 2 or 4 MIMO
att_tx = 16 # for indoor measurments. Put 0 only in outdoor
att_rx = 0; # for indoor measurments
eNB_instances = [0];
bands = [78];
nr_flag = 1;
sl_ahead = 5; # is the good value for 2.5ms TDD to avoid tx/rx overlapping
##beamforming 1x2 matrix: 1 layer x 2 antennas
bf_weights = [0x00007fff, 0x0000];
}
);
rxfh_core_idandtxfh_core_idshould be different and on the same NUMA node as the network card that is being used. In this example the NUMA node has all odd cores. Ideally, they should be isolated from the OS because they are used close to 100%, and we don't want the OS to put anything on them.- when running check the allocations of the 2 cores with
mpstat -P ALL 1. You should see that coresrxfh_core_idandtxfh_core_idhave%syswhich is high (this is thekthreadsassociated with the two fronthaul threads). You should also see the%softirqhigh, and it should be on a different core than the 2 FH cores.irqbalancerservice should be on (with O-RAN it is off and IRQs are specified also). - There is a thread-pool for the RU entity.
num_tp_coresis the number of cores for RU andru_tp_coresare the indices, if you want to specify them. If you don't specify the indices it lets the OS choose. If you reserve cores for OAI withisolcpusthen you should put these on those reserved cores.
RF Simulator
rfsimulator :
{
serveraddr = "server"; # server = gNB side
serverport = "4043";
options = (); #("saviq"); or/and "chanmod"
modelname = "AWGN";
IQfile = "/tmp/rfsimulator.iqs"; # location in which the IQ samples are saved
};
CU-DU split
For the CU:
- Maintain the section relate to the AMF GTP connection:
amf_ip_address = (
{
ipv4 = "127.5.2.2"; # AMF interface IP address used for the NGAP. Syntax: do not specify the network mask (e.g. /24)
ipv6 = "192:168:30::17"; # Not relevant
active = "yes";
preference = "ipv4";
}
);
NETWORK_INTERFACES :
{
# In this section it is required to specify the interface name and IP address use by the gNB to communicate with the AMF.
# In this specific case the AMF is located in the same machine as the gNB this is why the addresses are in local host.
# In case the AMF resides in a different host of your LAN use the appropriate network interface
GNB_INTERFACE_NAME_FOR_NG_AMF = "lo"; # interface name
GNB_IPV4_ADDRESS_FOR_NG_AMF = "127.5.2.130/24"; # syntax specify the Network mask (e.g. /24)
GNB_INTERFACE_NAME_FOR_NGU = "lo"; # interface name
GNB_IPV4_ADDRESS_FOR_NGU = "127.5.2.130/24"; # syntax specify the Network mask (e.g. /24)
GNB_PORT_FOR_S1U = 2152; # Spec 2152 do not modify
};
- add in the gNBs section the following parameters
force_256qam_off = 1; # Important. For now the 256 QAM is not enabled with OAI CU-DU split
tr_s_preference = "f1"; # indicated the split option
local_s_if_name = "lo"; # Indicates the CU interface name to dialog with DU. In this case they are both located in the same machine so the interface is in localhost
local_s_address = "127.0.0.4"; # CU address
remote_s_address = "127.0.0.3"; # DU address
local_s_portc = 501; # used local CU port tc
local_s_portd = 2152; # used local CU port td
remote_s_portc = 500; # used remote DU port tc
remote_s_portd = 2152; # used remote DU port td
For the DU:
- The section related to the AMF/GTP connection disappears because it's not anymore necessary since the CU is the one connecting to the CN
- In the gNBs section remember that for now
force_256qam_off = 1;(256 QAM is not active for CU-DU split) - In MACRLCs section
MACRLCs = (
{
num_cc = 1;
tr_s_preference = "local_L1"; # not local_RRC
tr_n_preference = "f1"; # specify the F1 split
local_n_if_name = "lo"; # Indicates the DU interface name to dialog with CU. In this case they are both located in the same machine so the interface is in localhost
local_n_address = "127.0.0.3"; # DU address
remote_n_address = "127.0.0.4"; # CU address
local_n_portc = 500; # used local DU port tc
local_n_portd = 2152; # used local DU port td
remote_n_portc = 501; # used remote CU port tc
remote_n_portd = 2152; # used remote CU port td
pusch_TargetSNRx10 = 200;
pucch_TargetSNRx10 = 200;
}
