- Removed ntn_koffset, ntn_ta_common, ntn_ta_commondrift arguments in order to be used directly from SIB19
- Removed global NTN_UE_Koffset variable and it's use
- Introduced getter functions for ntn related parameters
Using ITTI calls for user plane implies (1) a memory allocation, (2)
mutexes, and (3) queueing messages for each user plane packet, which is
heavy. Use a direct API call instead to reduce overhead.
- Added new structure to hold timing advance parameters
- Made SIB19 related calculation to save to this struct
- Modified in ra to get ta struct values
Move handling of sync request from MAC from UE_dl_preprocessing(). This
will process the sync request before receiving the samples of current
slot from radio so we don't 'lose' the slot.

Fronthaul xran library update to F release (2. and final step towards M-plane integration)
- xran library support -> both E and F releases
- RU delay profile removed -> not used in neither of the releases
- DU delay profile updated
- one-way delay measurements support is improved/fixed in the F release.
However, not implemented here as it depends on the RU capabilities
The "mgmt_addr" parameter is not required for USRP N310 initialization. The
critical parameter for successful operation is the "addr", which specifies
the IP address of the SFP port used for data transfer.
Including both "mgmt_addr" and "addr" can lead to initialization failures if
one of the specified addresses is unavailable. Since the "mgmt_addr" is
unnecessary for this context, it has been removed to avoid potential conflicts
and simplify the configuration.
Fix incorrect array type of determ_fin which was set to int32_t while the
array holds the results of simde_mm_abs_epi32 which produces unsigned
values.
Remove assert on right-shifting negative integers as it is impossible for
determ_fin to hold negative values.
Change type of sum_det to uint32_t to prevent possible overflow.
Fix the type cast (int -> uint32_t) to prevent casting before shift in
nr_ulsch_comp_muli_sum which might have resulted in right shifting negative
integers.
Updates to match more fapi-compliant tx_data.request
The packing of PDUs as required in aerial for the Tx_data.Request wasn't
complaint with FAPI. That was fixed in Aerial 24-2. This change makes L2
pack the payloads in the way that Aerial now requires.
remove un-necessary global variables
Remove global variables that can be removed by a trivial way:
- simply dead globals
- or reference is a single source, so can be static
setting them static reduces the scope, that is a progress, but of course as
for all static variables, the code is still not re-entrant
Major improvements:
1) bbu_offload - enable packet handling on BBU cores
2) dlCpProcBurst - DL CP processing on one or more symbols
3) SRS CP processing - depends on the RU capabilities that can be
retreived via M-plane (if RU is CAT B)
4) nSecDesc - the number of section descriptors per symbol; it was hardcoded to 0 in E release;
depends on the RU capabilities that can be retreived via M-plane
5) RunSlotPrbMapBySymbolEnable - enable PRB mapping by symbol with multisection;
depends on the RU capabilities that can be retreived via M-plane
6) DSS (Dynamic Spectrum Sharing) support - depends on the RU capabilities that can be retreived via M-plane
Minor fixes in F that exist in E:
1) prach_config->nPrachFilterIdx - explained in commit ID f3045396
2) T1a_min_cp_dl - explained in the commit under title "Clarification on DU delay profile"
3) fh_config->nULRBs - explained in commit under title "Further clarification on xran E release parameters"
Removed const for prb_conf argument in oran_allocate_cplane_buffers()
function, as F release requires the not const struct for
xran_init_PrbMap_by_symbol_from_cfg() and xran_init_PrbMap_from_cfg()
even though the struct is not modified inside of these functions.
- remove xran parameter io_cfg->port logging => this parameter
is filled within xran library in both E and F releases
- PRACH offset explanation; not limited to >= max(Ntx, Nrx);
workaround done in xran to support PRACH eAxC IDs same as PUSCH eAxC IDs
- DL PRB not used in xran; UL PRB used in xran F release, therefore
removed from the patch
- these fixes should have been done in the commit ID f3045396
Align YAML config getlist with libconfig implementation
This aligns the behavior of params_yaml with params_config library:
- when a mapping is read using getlist it returns the number of elements in
the mapping instead of 0
- when a mapping is read using get it returns the number of parameters used
for input
CI: Allow restart of the container if deployment fails
In CI we sometimes encounter fail of the gNB/UE deployment (and fail of the test
scenario) caused by unsuccessful initialization of the USRP N310.
This MR enables to optionally restart the gNB or UE container, if the deployment
fails on the health check during start up. By default, restarts of the container
are not allowed, but we can enable them by setting num_attemps > 1 for a given
deployment in the XML file.
Logs from failed deployment attempts are collected.
This MR aims to avoid known CI failure caused by "USRP N310 Initialization Failure"
mentioned in #871.
Documentation: add multi-UE deployment with RFsimulator
Extended doc/NR_SA_Tutorial_OAI_nrUE.md with section about how to run multiple UEs
- multiple UEs with namespaces (provided new script)
- multiple UEs with Docker UEs
- updated rfsimulator and channel simulation tutorials
- updated README.md
This change makes it so the fapi_nr_p7_message_pack is used to pack TX_DATA.request for Aerial, reducing the amount of repeated code.
Add the capability to pack TLVs with TAG=2 (offset from first address)
Packs the TLV.length differently according to whether or not Aerial is in use ( for Aerial TLV.length is 16-bit, for OAI is 32-bit )
In CI we sometimes encouter fail of the gNB/UE deployment (and fail of
the pipeline) caused by unsuccsessful initialization of the USRP N310.
Restart the container if the health check fails during initialization.
Introduce a configurable parameter (from XML) to set max number of
attempts for the container deployment.
Store logs from failed deployment attempts.
Rework GetContainerHealth() to work with docker compose and services,
instead of using docker and containers. Return health and message about
deployment status (used for console and HTML logging) for a given service.
T tracer: add macpdu traces for the NR UE
MIB, SIB1, random access and regular scheduling are traced.
At the beginning of a connection (rrc setup request and rrc setup), the
RNTI is reported as 0. Might be fixed, somehow, if absolutely needed (not
sure).
