Pedro Alvarez debb4a0c6b Refactored RLC AM segment pool for re-use in both LTE and NR 
Moved RLC AMD PDU definitions from rlc_am_lte.h to rlc_common.h to make them re-usable in both RLC LTE and RLC NR
 3 years ago
Pedro Alvarez 54be15e7a6 Moved write pdu to rlc_am_base::rlc_am_base_rx 3 years ago
Pedro Alvarez 476f9e1156 Changed logger initialization in RLC AM entities 3 years ago
Pedro Alvarez 022c51493b Refactored RLC AM NR/LTE Rx and Tx entities to use a rlc_am_base_rx/tx class. 
This was done to make it easier to share entity specific code between LTE and NR.
This removes the previously used templates.
 3 years ago
Pedro Alvarez b15f63f32f Added an RLC AM base class to avoid code duplication in the RLC AM NR entity. 
This class is based on a template that receives as argument the
rlc_am_*_tx/rx entities, so that those are different for LTE and NR.

Moved code from rlc_am_lte/nr entities so that they use the new base class.

Asynchronous NR PHY configuration (#3527) 
* Fix a race condition when accessing the NR PHY cfg by the RRC and phy workers.
Rework how the phy cfg is handled, now workers have their own copy that gets updated after a reconfig moving it out of the state class.

* Default initialize sf_len member in sf_worker for consistency.

* Asynchronous NR PHY configuration

* Fix compilation

* Corrected method override and fix unitialised value

* Added carrier equal comparison to avoid aligment byte padding comparison

Pedro Alvarez fbcffb84bd Check if RLC is suspended before transmiting PDCP SDU. 
This was done to avoid integrity issues, when the UE's RRC erroneously sent
measurement reports while the re-establishment was already in progress.

As errously sending PDCP PDUs on DRBs can cause issues as well, this was
disabled too.

Andre Puschmann cc2d71183e ue,phy,nr: fix race condition when setting UL grant for Msg3 
the Msg3 UL grant requires the TTI in which the RAR has been received
to calcualte the correct timing. There was a race between PHY and Stack
thread.

This patch circumvents the issue by removing a PHY state member that only holds
the RAR Rx timing. In the new interface the RA proc passes the Rx TTI
to the PHY again when setting the UL grant so the PHY can calculate the
correct timing without any state.
