The changes done in this commit are to contribute the supporting changes
for the existing "Initial support for RedCap" feature in gNB.
In this patch, handle and store the RedCap related IE's present in "NR
UE Capability Information" msg which are
- 'supportOfRedCap-r17'
- 'supportOf16DRB-RedCap-r17'
- 'longSN-RedCap-r17'
- 'am-WithLongSN-RedCap-r17'
use 'longSN-RedCap-r17' and 'am-WithLongSN-RedCap-r17' IEs to set the SN
length to either 12 Bit or 18 Bit accordingly.
Improvements to the FHI for enabling further use cases
These changes to the FHI were primarily thought to enable the integration of
the intel ACC ( !3344 ) in parallel of the FHI.
I preferred to make a separate MR because I believe this topic is orthogonal
enough to be handled separately and because I wanted to bring even further
improvements.
The improvements that it actually brings are:
- Enable compiling and running xran F release with DPDK 21+
- Enable including a BBDEV device in addition of the ethernet device for the
FHI when performing EAL init, which is necessary for using the intel ACC
with the FHI.
- Fix an issue in usage of pkgconfig in xran E and F release. This enables to
reliably build xran with the version of DPDK requested to pkgconfig while
before this fix xran was always selecting the headers installed in /usr/local.
Split out type and function definitions for a cleaner separation for
some consumers of these functions. Concretely, nr_mac_common.h includes
various ASN.1 NR RRC headers, but not all consumers of these APIs might
need these headers. For instance, the next commit will use these
functions in the driver for 7.2 (it needs to compute PRACH length), but
the driver itself does not depend on nor does it need the ASN.1 NR RRC
headers. Defining a new header avoids the problem.
bugfix: UE AMBR is optional
This was a problem with open5gs and more than one PDU session. The core network
sets UE AMBR only once, leading to failure in the gNB for the second PDU session.
(A proper handling of AMBR has to be develop at some point in the gNB.)

continuously update SIB19 information for rfsim NTN LEO scenarios
Contains mainly these changes:
- gNB: add function nr_update_sib19() allowing to update SIB19
information
- rfsimulator: update SIB19 contents every frame for LEO channel
simulations
- NR UE: improve initial timing advance calculation from SIB19
Before, we only considered ta_Common_r17 and the SAT position from SIB19
to compute the initial timing advance value. This is good enough if the
satellite does not move too fast (e.g. GEO satellite).
Now we also consider ta_CommonDrift_r17, ta_CommonDriftVariant_r17 and
the SAT velocity together with the epoch time from SIB19. This improves
the accuracy of the initial TA computation, esp. for LEO satellite
scenarios.
Various fixes for UE handling, HO doc updates
- On release request, search both attach and connected list to free a UE.
- on DU disconnect, only release the correspnonding UE contexts.
- When no AMF for the UE, auto-release the UE (NGAP would also send an
answer, but better check first)
- implement a "grace period" before the DU/MAC automatically releases a
UE: this is to avoid cases in which (for whatever reason) the UE
release request is not honored by the CU. In order to not fill up UE
contexts unnecessarily, the DU will eventually (after 10s) drop the UE
context
- some clarification in HO tutorial
When the RA procedure fails at Msg4, we trigger UL failure and send a
message to the CU to request release. There was a bug in that upon the
ensueing release command, we did not search in the attach list (only
connected list). However, the UE failing at Msg4 does not have
transitioned to the connected list yet, thus not freeing the context.
Fixes: 8f62baefa6 ("Use list of UEs during RA instead of array of RA
processes)"
It might happen that the CU does not answer a release request. In that
case, the MAC would never free the UE context, potentially blocking the
DU. Avoid this by introducing a "grace period" after which a UE context
is automatically freed at the MAC (and RLC), currently at 10s after the
30s UL failure timer.
Mark non-existing AMF UE NGAP ID through invalid INT64_MAX number
(permitted range is up to 2^40-1). Check for this range in the RAN
function, as we might otherwise pass the invalid AMF UE NGAP ID to the
agent, which would assert with
nr-softmodem: /oai-ran/openair2/E2AP/flexric/src/lib/3gpp/enc/enc_gnb.c:83: enc_gNB_UE_asn: Assertion `gnb->amf_ue_ngap_id < 1UL << 40' failed.
In other words, don't send KPM messages for a UE which has no valid AMF
UE NGAP ID yet (which follows from the fact that the spec requires an
AMF UE NGAP ID; the previous behavior of simply sending 0 could be
considered a bug, because it's not the UE's true AMF UE NGAP ID).
NR RRC Reject UE
Improvements in procedures to handle RRCReject message both at gNB and
UE. At gNB we send RRC Reject if the UE cannot be given resources to go
into connected mode.
NR UE: enable CSI report for SISO case
Correct precoded_sinr_dB wrongly set to 0 for SISO case, also correct
ri_restriction is 0 when calculating CQI bit length for SISO.
Update/refine gNB MAC stats, update L1
Only applicable with -q option.
Print a number of statistics, e.g., rx_ulsch_sdu to track UL MAC stats
timing. Remove unused time_meas_t definitions, and fix the name for the
total gNB scheduler time.
Print the RU stats in nrL1_stats.log, as some are already there, and do
not "pollute" the periodic logs when -q is enabled.
I used this to see why there are sometimes late slots with Aerial. I
used the above stats to get a general overview. This additional patch
shows that at least in RFsim, the RLC indication in rx ulsch sdu can
take up to 20us on my machine. Given that we can have multiple PDUs in
UL (10?), this can amount to a sizeable amount of time. While this is
for another MR, I thought the cleanup would be nice to have.
Refactor F1 UE context messages, add unit tests
Add encoder+decoder+util functions for F1 UE context messages, and use
them in the stack. The overall goal is to unit test encoder+decoder (to
be sure that what we send is what we receive), and remove any memory
leaks related to F1 handling. Messages that have a unit test:
- F1 UE context setup request/response
- F1 UE context modification request/response
- F1 UE context release request/command/complete
This MR removes almost all remaining memory leaks that are observable in
a "standard" configuration, running SISO in RFsim. In RFsim (without
channel modelling), there are only two memory leaks shown in asan, one
in L1, and one in NGAP.
We use the same resource for CSI meas report and RSRP (judging by the
name of the functions), but the memory allocations need to be separate
to avoid a double free:
