Andre Puschmann 8ef0d6c6ca do not automatically consider cells for which a measurment has been received as "in sync"
the in_sync flag has been misused in some parts of the code
receiving a PHY measurement for a cell does not automatically
mean that we are "in sync", as it is used in RRC as a condition
to indicate if we are camping on cell

the in_sync/out_of_sync condition should only be altered by the
corresponding functions sent from the PHY for the currently selected
cell (and not automatically for all cells)

the commit also removes the deletion of cells which are not "in sync"
from the list of neighbor cells. Instead, RRC calls a clean-up function
peridically that deletes old cells eventually.

Francisco Paisana f2d88e5a5b simplified NAS rrc connection request procedure
move non-type-specific methods of proc_t to its base class.
procedure state machine was simplified via a future-type. Now procedures dont get stuck until the user reads the procedure outcome.
made the NAS procedures more event trigger/reaction-based.

Andre Puschmann 35307a047a make UE switch_on non-blocking
this allows a simpler main that just signals NAS to switch on the UE
but doesn't block until the action is completed.

For making sure the UE also attached if the first attempt failed
the NAS needs to be extended to support the correct timers.

Francisco Paisana 81a466a641 since we moved cell search to the background thread, cell reselection prints a error message that it cannot start. In fact it already started. It is just waiting for the cell search to finish. This PR fixes this 5 years ago
Francisco Paisana b1496317d5 fixed the pcch proc issue by letting the cell selection explicitly propagate its result to the pcch_process_proc 5 years ago
Francisco Paisana 2fb830fcfa moved cell search to background task thread pool, and provided a stack interface to rrc to call "start_cell_search". Once completed, the background task signals back to RRC 5 years ago

RRC-PHY interface (#639)
RRC-PHY interface refactor. Moved RRC-MAC interface to rrc_asn1_utils and created RRC-PHY interface also in rrc_asn1_utils. All ASN1 includes should be made from rrc_asn1_utils only keeping ue_interfaces clean of ASN1

Tested with different common and dedicated configurations (64QAM UL, 256QAM, CA, SRS enabled/disabled, etc)

Francisco Paisana 67d6a25194 Moving mac timers to stack timers (#638)
* first step towards moving MAC timers to stack. Mac is still using its own timers. srslte::timers class can be restructured.

* moved timers out of the UE MAC

Francisco Paisana bb0dbf0f1c created a asn1 utils with helper functions and types related to the asn1. These types/functions will help isolate the rrc_asn1 lib from most of the layers, reducing this way the compile times, and leading to better isolation. This will also make the transition to NR smoother. I removed the asn1 types from the NAS and USIM interface so far. 5 years ago

Andre Puschmann 58763fb714 stack: move initialization of log object into ctor
this fixes the issue when the stack is torn down if, for example,
the radio couldn't be loaded correctly. it will hence call stop() on all stack
components which are not initialzized yet, and logging therefore doesn't work.
the log object is know during contruction time and therefore can be passed
in as soon as possible.

Andre Puschmann 3f613d7183 nas/gw/rrc: make LCID for DRB dynamic
- add interface to RRC to allow NAS to query the DRB for a given
  EPS bearer id
- extend interface for NAS to setup GW to also pass LCID of bearer
- in NAS, use this new interface to pass actual LCID of the default
  DRB when creating the TUN device

Andre Puschmann 65f50cd7ba introduce new UE layer design
- abstract UE object now consists of a radio, a PHY, and a stack layer
- add new stack abstraction layer that combines MAC, RLC, RRC, PDCP, NAS and GW
- PHY layer now has a single stack interface and does not talk to MAC and RRC seperatly
