Fix SRS report TLV unpack
Changes the SRS unpacking to not expect padding to be present in the buffer when
working with Aerial, with which the report TLVs are not padded to the nearest
32-bit boundary. This issue was found when using a UE with 1 SRS port, which
causes the TLV to not have a length divisible by 4. Also adds a function to pull
X amount of bytes into a uint32_t, which is used to process the last 4 byte
block of the TLV, only pulling the bytes which are not padding. Completed the
SRS.indication dumping procedure to print out the report TLV. Changed the
SRS.indication unitary test to fill the last 4 byte block of the report TLV
appropriately according to the length ( which ensures the padding bytes are set
to 0 )
This is not really used as of now, because most IPs are hardcoded. See
one of the next commits for the use of this.
To make sure that we have the correct IP, there is some code that
verifies that a hardcoded IP and the CN IP would be the same.
Note: need two separate ci_infra.yaml entries, because
- for FlexRIC, the container name is different (is the tutorial CN)
- for RFsim5G E1, we don't have ext-dn => ping UPF
- call scripts for magma MME-based deployment of OAI 5GC in
ci_infra.yaml
- implement the existing python code through scripts (which does the same)
- save the cql file in the repo, which was previously downloaded every
time
- use for porcepix-cn4g and nano-cn4g (un)deployment, ping, perf, in XML
files
- Use scripts to deploy OpenShift-based 5GC in ci_infra.yaml
- Use for oc-cn5g, oc-cn5g-20897, and oc-cn5g-20897-aerial2
for (un)deployment, ping, iperf in relevant XML files
- Convert hardcoded IP addresses to %cn_ip%
Use the core network class to configure one "end" of these tests. This
will make the tests more generic and predictable, as they are explicitly
configured through two ci_infra.yaml "entities", instead of some
implicit "EPC" IP address given in configuration.
As of this commit, no XML passes this info into the framework, so no XML
step will work. As it is many changes, the following commits will add
the necessary info one by one.
This adds a helper class to manage various core networks in the CI
testing framework. Specifically, it reads from a YAML file information
such as a node, (un-)deployment script (file), log collection
instructions, etc., in order to allow a common interface to be used to
deploy and undeploy various core network implementations.
This commit adds the class (in cls_corenetwork.py) as well as tests for
this class.
FHI72: Management plane support
At the moment, tested with Benetel 550 and 650 RUs FW v1.2.2
- support for multiple RUs
- RPCs implemented: <connect>, <subscribe>, <get>, <supervision-watchdog-reset>,
<edit-config>, <validate>, <commit>, <disconnect>
- read PTP sync status from operational datastore xml
- get vendor name, and for xran store RU MAC, MTU and IQ bitwidth and PRACH
offset, and transfer this info
- store interface name, low-level-tx/rx-endpoint names, tx/rx-carrier names,...,
from operational datastore xml
- add reference gNB/DU config files with M-plane support
- update FHI readme
Add documentation for Foxconn RU
This MR adds documentation for using the Foxconn RU with OAI, as it piques the
interest of some in the community. Note that this RU is not continuously tested
with OAI L1. Additionally, we have observed throughput degradation in OAI
versions beyond tag 2024.w30, and the issue is under investigation. For now, we
are providing documentation based on what we have tested in our lab.
K-offset updated with configured sub carrier spacing
According to 38.331 , cell specific K-OFFSET provided in SIB19 is provided in
number of slots as per 15Khz SCS Koffset before being applied, needs to be
updated to the slots according to the configured subcarrier spacing.
- Increase the maximum logging line for print done through
log_output_memory().
The reason is that we hit this line length when printing some machine
generated configuration (XML) through the M-plane. Increase to make
more of it visible.
- To limit the impact, only increase this locally in function
log_output_memory(), and statically assert that it will never be
larger than 64 kB.
In other places, we use the old limit.
- Move the definition MAX_LOG_TOTAL to log.c, because it's only used
there.
- if RU(s) are not well configured, disconnect immediately and stop the DU
- if all RUs are well configured, proceed with waiting until ready. The RU is
ready when the carriers are activated. Either the RU already has preconfigured
carriers (previous M-plane client configured), or the DU has to wait until receives
the notifications.
Ideally, we should load the yang models from the RU operational datastore, but the issues are following:
1) the yang models order is not good - dependancy models have to be loaded first
2) earlier O-RAN yang versions (e.g. v4) is not properly defined (i.e. optional parameters should not be included by default)
Added support in both cases, loading from RU with <get-schema> RPC, and loading statically from "radio/fhi_72/mplane/yang/models" folder.
Add a function pullx32 to pull x amount of bytes into uint32_t
Change the unpacking to pull only the needed bytes, and skip over the padding, when not Aerial
Change SRS.indication dumping function to also print the report TLV contents
Change SRS.indication unitary test to fill the last 4 byte block of the report TLV according to the length, with padding
Shared memory realtime radio simulation
Realtime and near-realtime RFSimulator alternative without channel modelling.
The purpose of this library is to allow realtime simulation of gNB and nrUE.
The library is loaded using --device.name vrtsim. The server side (gNB) should
also configure --vrtsim.role server and --vrtsim.timescale according to
requirements.
Limitations:
- Only 1UE-to-1gNB connection supported
Future work:
- Telnet API
