[srslte-users] srsENB SIB10/SIB11 functionality

[Francisco Paisana]

Hey,

It is hard to answer your question shortly in a comprehensive manner, so I
will try to list what comes to mind:
- if you want to make the parameters of the sibs 10 and 11 configurable
through "sib.conf", you can add the respective parsing functions in the
enb_cfg_parser.cc. You can get inspiration from the other sib examples.
Otherwise, write a hardcoded sib configuration in the srsenb rrc.cc file.
- packing/unpacking of sibs is done through the rrc_asn1.h library. You can
look at examples already done for other sibs.
-  for the UE to request sibs 10 and 11, you will have to add these numbers
to the array required_sibs[] in the srsue rrc.cc file (unfortunately, it is
still a hardcoded list).
- the srseNB generates the sib messages in its rrc::generate_sibs()
function and passes it to the mac for scheduling in the rrc::config_mac().
Make sure you are telling the mac to broadcast sibs 10 and 11 via the sib1
si scheduling list.

Regards,
Francisco
