Fix PDSCH and PUSCH BWP Start and Size when PXSCH is scheduled with a DCI format x_0 in any type of PDCCH common search space
- Fix PDSCH and PUSCH BWP Start and Size when PDSCH/PUSCH is scheduled
with a DCI format x_0 in any type of PDCCH common search space
- Fix resource block assignment information (RIV field) for DCI format
x_0 when scheduling in any type of PDCCH common search space
Move this message down, at the end of the function, if no code path
exists under which msg3 allocation might fail despite this log having
been printed.
Assume the minimum grant (min_rb) size to be the bandwidth part size. As
an example: rbStart 0, min_rb=bwpSize=106. This should pass, hence
modify these two conditions.

Signal gNB-DU config update CellStatus from DU to CU
Add the cell status to gNB-DU configuration update message, including
test. Use the gNB-DU configuration update to signal the cell status in
the stack.
This IE was not included in a previous refactoring round, but is at
least necessary to be decoded when interoperating with the OSC O-DU.
Improvements in handling UE context in gNB DU
The goal of this MR is to improve the handling of UE context in gNB DU.
To achieve this goal, the UE structure is created as soon as the gNB
receive a PRACH indication. At that stage the UE is placed in a new
structure containing UEs performing RA, untill RA is complete where it
is moved to the list of connected UEs. To simplify the code and to
improve the handling of initial procedures (see #751), DCI 10 and DCI 00
is used at every stage until the DU receives from CU the indication of
UE RRC reconfiguration being completed.
Remove assert for SRI-PUSCH-PowerControl
SRI-PUSCH-PowerControl is not implemented at this point but its enough
to warn about incorrect power control behavior rather than assert on the
configuration.
Closes#953
Add functionality to trigger the addition of a new RRC UE context (in
the CU) for NSA modes, using F1. This commit makes do-ra and phy-test
modes work. "True" NSA will work in the next commit, which also sends
the X2 addition request answer message.
Use the gNB-DU configuration update to signal the cell status in the
stack. At the DU, modify the code to always send this message --
previously, we only sent this message if a SIB1 update was necessary,
but now it's always, only including SIB1 updates if necessary.
At the CU, as we don't really have a use as of now, print the
information, but don't do anything with it.
- rewrite add_UE_to_list() and rewrite remove_UE_from_list() to simplify
list handling
- return pointer from get_new_nr_ue_inst(); it's completely freed by
delete_nr_ue_data()
- have add_new_UE_RA() add UE context to access list; remove with
nr_release_ra_UE()
- have add_connected_nr_ue() only add UE to connected list; to move from
access to connected use transition_ra_connected_nr_ue(); remove with
mac_remove_nr_ue() as previously
- free memory on problems during RA
- add some documentation
- in NSA/HO: check for pre-configured RA process
- there are asserts in all functions to clarify when a UE has RA
SRI-PUSCH-PowerControl is not implemented at this point but its enough
to warn about incorrect power control behavior rather than assert on the
configuration.
Fix for NR UE DLSCH decoding barrier in case of no feedback
In !3291 NTN CI RFsim test fails with the UE being stuck. After some
investigation, this seems to be caused by the scenario where there is no
feedback for DLSCH. In that case there is no need to wait for DLSCH
being completed before generating feedback (there is no feedback).
Fix ASN1 struct double free
When paging, RA and other SI have same PDCCH search space, we should
free the struct once and reset the other pointers to NULL.
Improve radio for Metanoia RU (and likely others)
We introduced a regression that lowered the achievable DL throughput
with at least the Metanoia RU (i.e., in the configuration and the UE
that we use). git bisect showed up one commit, which does not seem
necessary. We just revert this commit, as it improves the throughput and
does not seem to have a negative impact on performance.
Further, increase RLC buffers a bit. Limit 7.2 pipeline number of layers
to 2.
The UE stores PDCCH search spaces from the network in NR_BWP_PDCCH_t
struct within NR_UE_MAC_INST_t. After storing, the pointers otherSI_SS,
ra_SS and paging_SS are updated to point to the stored SS. Multiple
pointers could point to the same stored SS struct depending on
configuration. Then when the UE wants to release the SS, the pointers
are used to free the stored SS using ASN_STRUCT_RESET(). If multiple
pointers point to the same SS, calling ASN_STRUCT_RESET() on all
pointers would lead to double free. So one needs to check for dangling
pointer before freeing.
Instead of using pointers and assigning them during configuration, we
use SS id for otherSI_SS, ra_SS and paging_SS to retrieve the pointers
whenever needed. When the UE wants to release the SS, we make them -1
indicating an invalid SS id.
Issue 947 and compilation improvements
This MR started with a small commit (03c7f151) to close#947. Little did
I know that I would be taken in a long journey through OAI compilation
hell.
