Renames nfapi_nr_srs_reported_symbol_t prgs into *reported_symbol_list for two reasons:
So that the name is more representative of what the parameter represents.
For it to actually be a list, and not assume only 1 reported symbol is used.
Allocate reported_symbol_list in unpack_nr_srs_beamforming_report.
Updated all references to prior prgs to point to the first position of reported_symbol_list, still only effectively using the first reported_symbol.
Rename fill_srs_reported_symbol_list into fill_srs_reported_symbol and update input parameter name, since it only fills the information related to one reported symbol
Update NR P5 and P7 nFAPI headers to have 32-bit message_length
In the NR functions, this causes the header parameters following message_length to have their position shifted by 2 bytes, due to the increase in message_length size.
Change needed to accommodate SCF222.10.02 Table 3-3
Separates nfapi_p4_p5_message_header_t and nfapi_nr_p4_p5_message_header_t
Change the callbacks signature to accept/return void* intead of expecting a particular header type, being the NR/LTE distinction done inside the callback functions.
Create NR related functions for nFAPI transmit timestamp and checksum calculation.
Move nfapi_p7_codec_config_t and nfapi_p4_p5_codec_config_t to separate header to be shared between LTE and NR VNF/PNF
Move nfapi_nr_timing_info_t into NR header.
Move NR specific function declarations to NR header.
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.
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.
* trigger re-establshemnt on DU: reset RLC counters on DRB 1
for OAI UE, since SRB 1 does not work for lack of periodic
measurements reports
* how is the re-establishment triggered?
* a transmission on DRB 1 occurs
* detection of a mismatch of RLC counters at the UE side
* max number of RLC retransmissions reached
* RLF detection
* verify re-establishment on CU: we ping the core from the UE; this
sends packets on DRB, and because the sequence number mismatches, will
trigger a reestablishment. We accept in the ping that a couple of
packets might be lost; after ping is over, reestablishment must be
done as well (else the ping will already fail).
Added support for NTN FDD FR1 bands 254, 255, 256 as specified in 3GPP TS 38.101-5
Conf files added for 15Khz, 5Mhz and 30Khz, 10Mhz configurations added for these bands
In some runs of a multi-UE deployment, we see segfaults because
cell_group->spCellConfig is NULL. We should not segfault in that case,
so check for spCellConfig.
When the UE list is full, the iterator will run through all
MAX_MOBILES_PER_GNB UEs. It expects that eventually the pointer is NULL,
which is not the case if we have MAX_MOBILES_PER_GNB (or it simply
depends on the following memory). So give one array entry more, to
ensure that the last one is NULL.
If the RLC cannot retransmit a package, 3GPP specs say that we should
declare radio link failure (RLF). Up to this commit, the code did
nothing though. In this commit, add a per-UE RLF callback; the RLC will
call into this function to signal that RLF has been detected through
maximum retransmissions on a particular RLC bearer.
Extract nr_ra_procedures.c into a separate library and add 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
Set SA mode as default
- Set standalone (SA) mode as the default.
- Adjust commands in Docker Compose files by removing --sa flags and
adding --nsa flags where applicable.
- Add a function to verify that only one mode is being used at a time.
- Update all relevant documentation.
csiim_vars/csirs_vars used to be global array for each UE. Now its present
in phy_data which is in dynamically allocated memory.
MAC config was done without mutex while DL and UL threads could be running
at the same time.
get_ue_nas_info was allocating memory possibly from more than one thread.
Moved it into new init function for UE NAS layer.
Addreses most issues in #869
* the goal of this function is to initialize and configure the RAN Context
* the goal of get_options is to get command line options
* this commit aims at making the implementation more consistent
* move initialization of RC.nb_nr_CC to this function
* cleanup redundant initializations of RC.nb_nr_macrlc_inst outside NRRCConfig
* cleanup redundant initization of RC.nb_nr_macrlc_inst from getter function (get_node_type)
* cleanup RC initialization in RCconfig_NR_L1
* removed redundant log lines (print number of instances in NRRCConfig only)
* do RC init after getting CL options and configuration
* get_node_type shall access configuration only, not RC context
* NRRCConfig shall be called only once: made it thread-safe
* nb_nr_inst represents the number of gNB instances and the number of RAN contexts
* it used also to count the number of RRC instances in the node
* it is set from config file in NRRCConfig, therefore redundant checks after
this function have been removed
* redundant global variable NB_gNB_INST, set after nb_nr_inst, was removed
* gNB and L1 init is done in init_gNB and RCconfig_NR_L1
* moved RCconfig_nr_prs out of create_gNB_tasks for consistency
* do RCconfig_nr_prs only for L1 instances
* removed initialization of gNB
* separate function to get blacklisted UL PRBs
* call the getter in both L1 and MAC/RLC configuration
* other minor improvements
Fix Regression 4G
- Fix various bugs and/or regressions in 4G code
- Also, the CI does not test RFsim 4G with --sanitize, enables this to
detect problems.
Simplify logs in gNB&UE
- reduce the amount of printf() that outputs useless info
- in MAC, PHY, NGAP, RRC, mark some "important" UE events with LOG_A for
better visibility -> can put log_config.global_log_level analysis to
only see important stuff
- in RRC, use some macro to consistently print logs
- track the cellID of a UE in RRC
Moved some functions around so that instead of a function pointer a function
call is used. This enables inlining of functions which reduces number of function calls.
During preparation of SIB1, first digit of MNC was not taking into account.
This leads to XRES*, RES* mismatch during Authentication Procedure between 5GCore and UE because of derived serving network names.
