The simulators have been changed: due to linker errors that would arise
otherwise, a lot of functions are defined in them to avoid such errors.
Some functions are also defined in header files; in this commit, we
define most functoins in nr_dummy_functions.c, which is compiled in, not
by including the C file, but by adding it to the target in
CMakeLists.txt
- nr_dlsim+nr_ulsim need NR_IF_Module_init(), so it cannot be in
nr_dummy_functions, but the others need it
- Link correcr NR_IF_Module_init() into these simulators, and reduce
overall link list
- Correctly link remaining simulators
This commit provides CSI reporting support
which is required for MIMO. It also updates
the configuration files, provides sample BLER
simualtion files for packet dropping in the
MIMO 2x2 case. It also includes the hooks
and functions (e.g., updating UCI2_3_4 PDU field)
for MIMO 2x2 support. This commit will not include
any channel abstraction code or modelling.
After this commit, only the RNTI is used as an identifier in the MAC.
Further, it removes some module_id, but a lot of them remain (the goal
to remove all is still far from us)
This struct is used to store the uplink 5G nFAPI
messages between the proxy and the gNB MAC layer.
The original OAI implementation utilizes a similarly
named variable (UL_info) to store the uplink 5G nFAPI
messages between the PHY and MAC layer. This commit
will utilize the original UL_info variable prior to
calling the handle functions. These changes allow us
to make minimal changes to the nFAPI handle functions
and modifies the NR_UL_Indication parent function instead.
This requires some updates to the nFAPI code as well.
We also have declared the def_dci_rel15 extern variable
consistently throughout the code.
In this commit, the gNB is still crashing. However, it seems
that the NSA UE is sending the proper responses back, but there
some sort of incorrect management of the def_dci_pdu_rel15
variable. If we memset this array to 0, we can see incorrect
0 assignments to elements of the UCI indications. Hopefully
fixing this issue will result in less gNB crashes.
1. If matched rnti does not exist between crc_ind pdus and rx_ind puds, the ind or unmatched pdus will be requeued.
2. Sending crc_ind and rx_ind togetehr with crc_ind first in nrUE.
1. Changed hard coded preamble index(63) to soft coded.
2. Active UE will not be considered in gNB scheduging RA.
3. Added condition to process dci indication to handle multiple UEs.
4. Bug fix in mutex_lock (unlock to lock). It should be lock rather than unlock.
5. nr_ue_scheduler update not to entering into getting IP traffic to be transmitted in noS1 mode.
6. log update in checking the number of rx_ind or crc
