* Do not change sampling rate and calibrate time_adv_nsamples for b210
 5 years ago
Andre Puschmann 9ee415ac82 correct the max size for a single TB 
since the size in bits is counted per TB we don't need to allocate
space for the 2x2 MIMO case. Both CW have their own buffer.
 5 years ago
Andre Puschmann 21f8698397 fix MAC PDU packing for large TB sizes 
update the byte_buffer length variable after updating the remaining
PDU length. This has caused an error when calculating the
remaing space in the PDU because the SDU length was counted twice.

Andre Puschmann db196cc052 add RLC AM test for status PDU generation with small and big MAC grants 5 years ago
Andre Puschmann db9f093b63 add debug log when handling reordering timer 5 years ago
Andre Puschmann 849ad2655c fix creation of malformed RLC AM status PDU 
the issue was caused by an unneeded length check during the
assembly of the status PDU. This length check caused an too early
break from the while-loop that adds all missing SNs to the status PDU
leaving the PDU struct in an invalid state where ack_sn was equal to
one of the NACK_SNs.
The fix is to simply remove the length check during the generation to
fully generate the status PDU. If, for whatever reason, MAC provides
a too small grant to fully fit the status PDU, the PDU will not be
generated, i.e. the calling function checks the return value and does
not pass the (then too big PDU) down the stack.

Francisco Paisana b936629221 removed rrc asn1 header from bcd_helpers, from rlc_interface, and rlc tests 5 years ago
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 701db61fde rlc: extend stress tester to simulate MAC PDU corruption 5 years ago
Andre Puschmann ecb6a0f99b fixing RLC AM bug where corrupted PDU causes segfault 
the underlaying issue is that a corrupted PDU is passed to RLC
which claims to have segments whose total size exceed the size
of the entire PDU. Those PDUs are not ignored.

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.
