Improvements for PUSCH per symbol processing
- Improved the assert in task_ans.c
- Fixed and issue with PUSCH per-symbol processing that could cause an
issue in case num_pusch_symbols_per_thread is not 1.
NR gNB MSG3 TPC
This MR improves the handling of MSG3 TPC commands at MAC gNB.
TODO: Compute TPC when PRACH sends a valid power measurements (currently
not the case for OAI L1, to be verified with Aerial L1)
Closes#866
NR gNB improvements for analog beam management
- Improvements at gNB MAC layer to properly handle analog beam
management for all channels
- Simple beam switching mechanism based on UE RSRP report
- Introduced new configuration parameters `pusch_RSSI_Threshold` and `pucch_RSSI_Threshold`
(MACRLC section)
- Added `nr_limit_tpc` function in `gNB_scheduler_primitives.c` to limit TPC based on RSSI
threshold.
- Integrated `nr_limit_tpc` in PUCCH and PUSCH power control
Example Configuration
puxch_RSSI_Threshold takes value between -1280 and 0 and is mapped to range -128.0 dBm/dBFS
to 0.0 dBm/dBFS in 0.1 dB increments. Unit depends on RSSI reporting config.
pucch_RSSI_Threshold = -500; # Set the PUSCH RSSI threshold to -50.0dBm/-50dBFS
pucch_RSSI_Threshold = -600; # Set the PUCCH RSSI threshold to -60.0dBm/-60dBFS
chore(ci): improved errors messages visibility
1. There was a trailing && before $BUILD_OPTIONS in the command line
2. Added leading lines and more pattern to the grep command that
displays errors/warnings messages during docker build since we don't
have access to all.txt if build fails
nrLDPC_coding: improvements
One improvement in this changeset: Functions nr_interleaving_ldpc,
nr_deinterleaving_ldpc, nr_rate_matching_ldpc and
nr_rate_matching_ldpc_rx that were previously linked with the PHY layer
in the executables are now linked with the LDPC coding implementations
where they are called.
The parent commit cleans up and groups oai_exit in one place,
nr-softmodem-common.h. Therefore, this 5G file is included in the 4G
defs_common.h (at least it's mostly 4G), which is not nice. Instead,
define oai_exit also in 4G softmodem-common.h, and include this in
defs_common.h. Remove the cyclic inclusion of defs_common.h in
softmodem-common.h, and resolve all subsequent errors around unknown
types and extern definition mismatches.
Commit d641a76196 ("fix BSR report malformed, add SHORT BSR when it
can") removed code to fill the remainder of a TB, if it is not filled
with data from RLC, with random data when using phy-test or do-ra modes.
This random data filling is intentional, as it might prove useful for
demos or when debugging (e.g., to see used spectrum instead of 0, etc.).
Reintroduce the functionality, but unlike the original code, make it
dependent on the mode, not RFsim.
See also discussion in #888.
Fixup: d641a76196
Reduce race conditions through a itti queue, such that RRC-initiated MAC
memory modifications happen at the same time as MAC thread writes.
However, it doesn't resolve the problem of exact slot we should apply
the new cell configurtion.
This assert checks if the structure is correctly initialized. The structure
is one-time use so the assert is valid, but the value of the atomic was added
to the output to improve debugging.
Integration: `2024.w51`
