- identification of each parameter in fh_init and fh_config structs
- identification of unused parameters in xran library
- identification of parameters used for CAT A O-RU
=> CAT B not supported in this release
- pass parameter directly instead of indirectly via class
- harmonize to svr_id to harmonize parameter with parameters in the next
commit (and towards a future harmonization of directly taking node
names instead of "IDs")
The queue for finished jobs of PUSCH channel estimation is only used inside
nr_pusch_channel_estimation(). Since initialization is fast, it can be
declared on the stack in the function where it is used.
This commit enables the optional use of Tracy for profiling NR UE & gNB.
See https://github.com/wolfpld/tracy/releases/tag/v0.11.1 for details.
How to compile:
use -DTRACY_ENABLE=ON to enable instrumentation and sampling
For gNB currently only sampling is implemented.
How to collect data:
- Windows hosts: tracy-profiler.exe in link above
- Linux hosts: Compile tracy-profiler from source
Enabling collection from docker:
- open port 8086
- to collect cpu data
--privileged
--mount "type=bind,source=/sys/kernel/debug,target=/sys/kernel/debug,readonly"
--user 0:0
--pid=host
How to add instrumentation:
- See examples in this commit or manual in the link above.
Fix error reported by the T2 card when running nr_dlsim with 4 DL layers.
Error can be reproduced by running:
./nr_dlsim -n100 -s30 -e25 -b273 -R273 -x4 -z4 -y4 -P --ldpc_offload.dpdk_dev 41:00.0 -c
So far we set NR_LDPC_MAX_NUM_CB to 72, which is sufficient for max 2 DL layers.
Set max possible number of LDPC segments based on the max number of layers
and max number of DLSCH segments (currently it is 144).

Added NTN FDD FR1 bands defined in 3GPP TS 38.101-5
Added support for NTN FDD FR1 bands 254, 255, 256 as specified in 3GPP
TS 38.101-5. Example Conf files added for band254 for 15Khz, 5Mhz and
30Khz, 10Mhz configurations. Tested NTN GEO configuration on band 254
using these conf files.
There seem to be randomly occurring deadlocks when running the UE in the
CI. MR !3091 should fix this. While waiting for this, apply a workaround
by increasing the number of worker pools in the UE to 12.
Since tag 2024.w45/commit f54ca5714e,
standalone mode/--sa is the default and does not exist. Correspondingly,
it has been removed from the documentation.
For users reading recent documentation, but running an older version of
OAI, there might be a mismatch in that --sa is necessary to run OAI, but
not given in the documentation. Provide explanatory text to make users
aware of this.
Test for init_RA
A testcase for init_RA function.
The testcase redefines the following functions as stubs:
- nr_mac_rrc_ra_ind
- nr_write_ce_ulsch_pdu
- mac_rlc_data_req
- lockGet_ul_config
- release_ul_config
- remove_ul_config_last_item
- nr_ue_configure_pucch
These stubs can be used to check init_RA behavior
NR UE trigger for re-establishment
The implementation in this MR triggers RRC re-establishment at the UE in case
of radio link failure either for out of sync messages from lower layers or in
case maximum number of RLC retransmissions is reached.
