before entering RRC idle, after receiving a RRC connection release for example,
we need to wait until the RLC for SRB1 or SRB2 have been flushed, i.e.
the RLC has acknowledged the reception of the message.
Previously we have only waited for SRB1 but the message can also be received on SRB2
and in this case both bearers need to be checked.
The method is now streamlined to check both SRBs and is also used when
checking the msg transmission of an detach request.
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.
extend GW-NAS interface to signal test mode activation.
The method is a noop in the normal GW but is implemented in
the TTCN3 DUT according to TS 36.509 for Mode B
This commit implements support for the CLOSE_UE_TEST_LOOP message.
Currently the mode is not saved and looping the data is not implemented.
Only the *_COMPLETE message is sent back as a response.
First of all, with this the NAS conformance tests pass with ciphering and
integrity turned on. Before only integrity was working.
Mainly the NAS was applying the integrity protection and/or ciphering
incorrectly because it wasn't taking the secuirty status of the PDUs
into account. Some where already correct, some not. The patch
streamlines the handling for all outgoing messages.
during deinit of the UE/eNB it could happen that the log_ptr
was already set to null but the stack thread was still accessing
it through log_h->info()
i've moved the old macro into a new header and used as as much
as possible. there are still places in the code where similar
macros are used but we would need to change the variable name
to replace them
this is to better differentiate from "send_attach_request" that
only packs and send the actual attach request message. The
entire attach procedure may include PLMN search, etc.
* 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
* Use scoped lock in sf_worker
- move handling to NAS
- use switch off to enable airplane mode (don't wait for EPC response)
- add tiny FSM to control airplane mode activation/deactivation
- only start on/off counter after state has been entered
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.
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: prevent RRC from having serving cell in neighbour list
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
SRSUE: Removed SIC PSS from UE
SRSUE: fix inter-frequency reestablishment and added more traces
SRSUE: Fix compilation issue
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
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.
* Clang-formated UE, eNB and lib.
* Fixed compiling errors from clang-format.
* Fix linking issues introduced by clang-format
* Fix poor formating in initializing arrays of arrays.
* Fix mistake in conflict resolution on rm_turbo.c
* Re-apply clang format to gtpc_ies.h
before the type of some message wasn't displayed correctly,
like SIBs, for example because the logger didn't
know the filed to retrieve the type string
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.
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.
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.
the main issue was the plmn_selected variable. the solution
was to create a function to enter the deregistered state that resets the variable
and performs all other actions that need to be performed, like clearing
EPS bearers.
The patch also extends the SS to support AT commands to enable/disable
data services and now succesfully passes TC_9_2_2_1_7
* Calling tx_end() from radio_reset() causes long execution time in B210. Using boolean to call later instead. Fixes RLF failing in B210. Checked in X300
* Fix issue #655
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)
* 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
