Andre Puschmann 1e0c8ead4c srsue,sync: fix TTI gap calculation and reporting 
The current TTI gap calculation assumes strict continuity
of radio time stamps, even when retuning, changing sample rate, etc.

This is certainly desireble but not necessaritly the case and may cause
issues when negative time gaps or too large gaps are detected and reported
to the stack.

this patch makes the assumption that valid TTI jumps are between 1ms
and 1s and that larger gaps are the result of screwed time-stamps
or too long radio operations.

Improve robustness in RF Overflow (#1124) 
* Use task id to track old background tasks in RA procedure

* Improve robustness against RF overflow in PHY

* Increase SNR out-of-sync threshold

* Do not change frequency if it's the same

* Increase sync priority

* Increase time to start receiving to reduce input buffer occupation

Andre Puschmann c7343cf6d8 protect sf_buffer from overrun in receive_samples 
this patch adds a buffer len paramter to the receive_samples() call
that protects the (also) provided buffer from overflowing.

currently each call to srslte_ue_sync_zerocopy() which then calls receive_samples()
relies on a buffer that is "big enough". But that buffer is sometimes
2 subframes, sometimes 3 or 5, sometimes has space for the maximum PRB size, sometimes
only for 6 PRBs (i.e. during cell search).

By extending the interface to pass the buffer size we can make sure that
only samples are received that actually fit inside the provided buffer.

Xavier Arteaga f8294fb9df SRSUE: RRC measurements refactor and more fixes 5 years ago
Ismael Gomez 52716f8716 Process HO complete in the background to avoid heap-after-use bug when PHY measurements are reported during a HO 
rrc_meas refactor. Need to split commit

Fix typo

Temporal commit

Apply rx_gain_offset to neighbour cell measurements

srsLTE: modify TESTASSERT Macro to follow codeline

SRSUE: DL HARQ does not need Time Aligment Timer. UL is disabled using PUCCH resources release

SRSUE: extend intra-frequency to CA SCell

SRSUE: fix confusing/ambiguous code in the RRC measurements and fix concurrency issue

SRSUE: remove RRC measurement report triggers when measurements are modified or HO succesful

SRSUE: fix compilation issues and Reest SIB indexes

Fixes sync using incorrect cell configuration when search cell does not find a correct cell

Small refactor to remove measurement report triggers always after removing measurement

Andre Puschmann 4a9e3728c9 add condtional variable for PHY initialization and configuration 
adding a cond variable and mutex to protect init and (re-)config of PHY
currently this is only used during init. If the stack couldn't be
initialized but the PHY init thread was already started, we need to
properly wait until this is done
 5 years ago
Andre Puschmann 3127f59b4c wait with init of GUI until cell is found and initialized 
with the stack refactor we've introduced a regression in which
the GUI was started too early when no cell was found yet.

this caused the GUI to be initilized with only one Tx port. When connecting
to a cell with ports, the GUI plotter would then write
into unitialized memory.

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)
