[srslte-users] Issue when receiving long SIB by UE

[Taillefer Simon]

Hello srsLTE team,

We are having trouble with the reception of a long SIB message by the UE.

More precisely, the UE is not able to connect to the ENB because it timeouts if the SIB message with all other SIBs (SIB2, SIB3, ...) created on the generate_sibs function in the srsenb/src/stack/rrc/rrc.cc file has a length of more than 173 bytes.
The UE loops on the si_acquire_proc::init function in the srsLTE/srsue/src/stack/rrc/rrc_procedures.cc.
The raised error are the following:

-          [RRC ] [I] Proc "SI Acquire" - SI Acquire Retry Timeout for SIB2 from srsLTE/srsue/src/stack/rrc/rrc_procedures.cc file line 369.

-          [RRC ] [E] Proc "SI Acquire" - Timeout while acquiring SIB2 from srsLTE/srsue/src/stack/rrc/rrc_procedures.cc file line 376

-          [RRC ] [E] Proc "SI Acquire" - Failed to acquire SIB2 from srsLTE/srsue/src/stack/rrc/rrc_procedures.cc file line 320

Do you know if there is a solution to receive longer messages to allow the UE to connect with the ENB?

Thank you in advance for your help,

Simon Taillefer
