Implement FAPI P5 message unpack, as well as message length check function procedure in FAPI P5 library.
Update check_nr_unpack_length in nfapi_p5.c to reference FAPI P5 message length check function.
Will be reused from other files in later commits.
Added packing/unpacking procedures for STOP.indication and ERROR.indication.
Separate a packing function for STOP.request for use in the NR FAPI library.
Expose needed (n)FAPI procedures to aerial_lib ( both P5 and P7 ) via a
header file.
Move (n)FAPI P7 packing/unpacking function interface into separate header file
Include needed headers in aerial_lib
- Phy config update and Sidelink frame parameters initialisation
- PSBCH scheduler to trigger TX PSBCH/RX PSBCH actions
- Sidelink indication with rx ind to trigger send SL-MIB to MAC
- Enable Scope for PSBCH use -d or --dqt
- Enable system testing of PSBCH for example using RFSIMULATOR:
- UE1 is a SYNCRONISATION SOURCE UE which transmits PSBCH
started using command -
sudo ./nr-uesoftmodem --sl-mode 2 --sync-ref 4 --rfsim --rfsimulator.serveraddr server
- UE2 syncs onto UE1 during sidelink search, gets the timing and continues to receive PSBCH
started using command -
sudo ./nr-uesoftmodem --sl-mode 2 --rfsim --rfsimulator.serveraddr 127.0.0.1
- In the default use case 2 Sidelink SSBs sent over 16 frames.
- In case SL-SSB configuration needs to be changed use -O option in the above command like
-O ../../../targets/PROJECTS/NR-SIDELINK/CONF/sidelink_preconfig_1txpool.conf
Use common threadCreate() function to create P7 thread with high(er)
priority. Remove old calls to set_priority(), as this is already done
with threadCreate().

There is already a command line option called 'ue-scan-carrier' which
seemed to blindly look for SSB by changing the center frequency by
+/-100Hz if the previous attempt failed. This is probably copied from
LTE and is not suitable for NR. This commit uses this option to either
1. Perform initial sync on one GSCN if the SSB position if known
2. Or scan the all GSCN (if the SSB postion is unknown)
Also, the following is done for re-synchronization
1. Scan all GSCN when UE comes back from IDLE state
2. Scan one GSCN when UE does re-estabishment
Removed dependency of lte-softmodem.h in nr-softmodem.c.
CONFIG_HLP_UESCAN is declared also in lte-softmodem.h.
Some places (e.g., 4G eNB/UE nfapi mode) use numbers for the FAPI mode,
directly mapping to an enum. Aerial being in the middle messes up these
numbers. Put it at the end to limit possible problems.
