Francisco 43e57df00b breaking enb_interfaces.h into multiple files on a layer basis. Created enb_rrc_interfaces.h, enb_mac_interfaces.h and enb_s1ap_interfaces.h 2021-02-12 16:36:50 +01:00

Andre Puschmann 8e13f04684 mac_pcap: refactor MAC PCAP and include NR RAT into same object 
after adding the thread-safe PCAP writer functionality to the EUTRA
MAC object it became clear that we don't wont to replicate the
same for the NR object.

This patch therefore refactors the class that now supports both EUTRA and
NR rats. The old mac_nr_pcap.[h/cc] has been deleted. All test-cases
and usages now use the new object that needs to pass the RAT type in
the ctor.

this patch addresses the last open point of #2160

Andre Puschmann da9e3363f1 mac_pdu_nr: rename MAC PDU class for NR to adhere naming conventions 
* mainly to have _nr as trailing name for filename and class
* also add "sch" to class and filename (RAR PDU will have extra class)

Port enb specific classes to use srslog (#2155) 
* - Started porting the enb PHY layer to use srslog loggers.
- Updated srslog to manage the none level.

* Finished porting enb phy layer including the NR part.

* Ported MAC, GTPU, PDCP, RLC and S1AP enb classes to use srslog.

* Use new stack logger.

* Ported the enb RRC clases to use srslog.

* Remove unused log macros.

* Configure loggers in rrc_mobility_test.

* Fix compilation errors left out after the rebase.

* - Implement a custom log sink that will serve as a test spy to intercept and count the number of error and warning log entries.
- Adapt the erab_test_setup and rrc_mobility tests to use this new class and make them pass again.

* - Remove trailing new lines introduced in the rebase.
- Ported the sched_ue_cell class to srslog.

* Remove unused log member.

* Ported mac tests to srslog.

* - Removed remaining trailing newlines from log entries.

* Fixed a bug in srslog::flush that would never end when the backend queue is full.

* Fetch the RRC logger instead of injecting it in the constructor.

Francisco 99f94d9a1a Bug fixes of srseNB scheduler TPC 
- fix encoding of TPC command
- use of exponential average with irregular sampling for the ULSNR average estimate.
  Turns out using a time-windowed average for the SNR was a bad idea.
  If the UL grants are very sporadic, the SNR time window will never have samples
  when a TPC is encoded
- update of TPC sched test
- other fixes in accumulators lib

I now store the rnti and check if the rnti still exists.

Andre Puschmann a0e4b18507 enb_mac: pre-allocate UE object for quicker PRACH/RAR handling 
we've seen long delays in handling PRACH on low-power devices

in creating the UE object on the fly during PRACH handling.

This patch pre-allocates one UE object that is then used
during the PRACH.
