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 )

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.

- generate CU-planes RU configuration based on the loaded yang models and DU config file - not yet implemented for libyang and libnetconf2 v1

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.

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

- RU IP address - to connect to RUs via netconf - DU MAC address - for setting up the CU-planes on RU; not used in xran - VLAN tag (*) - for setting up the CU-planes on RU; not used in xran - DU keypair - for authentication when connecting to RU(s) The parameters that RU-controller shall retreive from RU list of capabilities: - MTU - compression - RU MAC address - PRACH offset (**) (*) VLAN tag is not used in xran but an option is given in fh_config struct. In my opinion, it is not a very suitable place, as it is needed for VFs. Therefore, I moved it in the initialization part for M-plane purposes. (**) PRACH offset shall be >= max(Ntx,Nrx), as per O-RAN CUS specification: "The O-DU may decide to use same eAxC ID value to address endpoints on different O-RUs, but eAxC ID values assigned to one O-RU must be unique within the O-RU’s endpoints of same direction." => however, LITEON supports flexible assignment of PRACH eAxC IDs, so we made a workaround in the xran library to support PRACH eAxC IDs same as PUSCH eAxC IDs.
