Until commit d74b2bd19f, the PSS detection step size was 4, anyways.
The PSS detection step size is a compromise between detection duration and accuracy.
The most accurate detection step size would be 1, but this would lead to even longer initial sync time.
- Introduced command line and configuration options to set up PCI address, CPU cores used by DPDK, and DPDK file prefix for T2 offload.
- Made the dpdk_dev parameter (for setting the PCI address of the T2) mandatory.
- Configure dpdk_dev in the CI test cases.
- Replaced bbdev TEST_ASSERTs with the OAI macro AssertFatal() to harmonize error handling.
- Removed unused functions and macros from nrLDPC_offload.h.
- Reworked nrLDPC_decoder_offload.c to process all segments in a TB with a single call to LDPCdecoder() or LDPCencoder().
- Perform CRC checks on the T2.
- Modified nr_ulsch_decoding (gNB decoder) to:
- Count processed segments.
- Properly perform CRC checks.
- Created a constant NR_LDPC_MAX_NUM_CB to define the maximum number of codeblocks.
- Conditional library loading:
- On gNB: Load ldpc_t2 library if offload is enabled using the --ldpc-offload-enable flag.
- On UE: Load both ldpc_t2 and ldpc libraries since only encoder offload is supported.
- General cleanup of nrLDPC_decoder_offload.c for improved readability and maintainability.
- Modified the structure of LDPC encoder/decoder/offload parameters:
- Introduced a structure for code block (CB) related parameters.
- Removed parameter E from the encoder and offload parameter structures for clarity.
- Replaced E with perCB->E_cb in the UE encoder code.
It seems libatlas-base-dev provided an `enum CBLAS_TRANSPOSE`, but we
don't install it anymore. Now, in Ubuntu, there is only a typedef'd
version in cblas.h; for RHEL(-derivatives), the same typedef'd version
is in cblas/cblas.h.
- 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
