Summary of changes:
- import work from Fujitsu:
- multiple UEs
- TDD configuration 1
- several bugs fixed:
- UE power changes
this one introduces two new parameters in the configuration file,
update yours! The new parameters are "puSch10xSnr" and "puCch10xSnr".
See targets/PROJECTS/GENERIC-LTE-EPC/CONF/enb.band7.tm1.50PRB.usrpb210.conf
- IQ replay module
- use MAKE_VERSION(x,y,z) instead of RRC_VERSION
- some UE fixes
Some new problems may happen. The work from Fujitsu was huge
and their branch diverged a lot from develop, leading to a very
complex merge.
The UE power management may also have an impact. It expects the noise
level to be at around 30 (as seen in the enb T tracer, in the
"input signal" view) and asks for an SNR of 20dB (value 200 for puSch10xSnr
and puCch10xSnr in the configuration file). You may want to put a
lower value, say 100 (SNR of 10dB). This is still work in progress
and needs some more work (we need to calculate the noise level at
runtime and not use a hardcoded value of 30).
This commit reverts the change coming from
675fd0af4e.
On a test machine, running the basic simulator (both eNB, UE
and T tracer) with 100 RBs eats too much of memory on a computer
with 8GB of RAM, leading to a reboot because the computer
was not responsive anymore.
Other solutions are needed to solve the memory issues, but
multiplying by 50 this number is not a good one, at least
not in the basic mode of operation. If this value needs
to be that big, a #ifdef #else #endif may be used.
20 was wrong, it means 2 dB.
200 is a bit high on my setup. Today the code hardcodes the noise
level as 30dB and a target of 20dB above noise is chosen by default.
Some more work is needed to estimate the real noise level. Some
more work is needed to set proper defaults.
- comment to GitLab merge-request does not anymore # as number (misinterpreted as issue number)
- added local build script w/ generation of HTML result file
Improvements on bash scripts:
- use of proper option parsing

Since now pucch_n1_AN is taken from the configuration file,
it has to be set to 0. Value 32 will not work well, at least
in FDD. This has to be handled properly at some point
(do not use uplink resource blocks used by PUCCH for PUSCH).
To minimize migration effort, we follow the logic of legacy macro Rel10 and Rel14 used
for conditional compilation of current code.
In the future, they might be changed to accommodate finer software configuration, e.g.
MAKE_VERSION(12,2,0) or MAKE_VERSION(13,1,0) .... etc.
Summary of changes:
- split UE and eNB directories
- nFAPI L2 emulator
- basic simulator
- various bug fixes
The nFAPI L2 emulator is not functional yet. Some code had to be removed
because it made the monolithic eNB non functional.
The unitary simulators (ulsim, dlsim) do not compile anymore. This will
be fixed later.
