Also fixed a few bugs in nr-nFAPI:
- Push16->push8 fix in packing of RACH
- Allocating memory for pdu_list and preamble_list in unpack
- Properly indexing through both lists during unpack
- Created new nr_rach handling function
Several other changes in this commit include:
- Setting the number of PDUS in the ul_config
to be zero when we will it (inside of the
get_ul_config() function.)
- We reset the nprach flag to 0 for each slot.
- We return out of the prach scheduler if
mac->ul_config == NULL
- Added error checking for array indexing
- Created a dummy scheduler response function.
- Allocated ul_config_req initially
Also calling the new L1_nsa_prach_procedures()
function after using the nr_ue_scheduler. Added
some error checking in the nr_ue_scheduler. Added
some error checking in the process_nsa_msg in both
the NR and LTE UE
Seems to be working at the moment but
may need to add more info in the rach_ind.
Also, need to verify gNB is getting the
rach_ind and starting RA procedure.
Had to hack the code to schedule the prach.
Need to verify this is ok because ul_config = NULL.
Also had to change logic for calling fill_schedule_response.
However, we are not properly calling the
nr_ue_get_rach() function. The RA is being
properly initialized. In the nr_ue_get_rach()
the pRACH is not scheduled. Tried to add in
the scheduling of this, but it crashes here.
The other changes include revering the
nr_ue_get_rach() changes from previous commit.
Also, changed a few log levels and reverted
a previous change in the NR UE RRC layer that
was incorrect.
Several places where memory ownership was changed
and the original owner was not set to NULL. Also,
the transaction_identifier is now based on the
received dl_dcch_msg in the LTE UE. Still need to
fix the t_id for the NR UE. Also added comments for
RACH procedure in NR UE.
This commit has several other changes. The changes
include the following:
1. Changed the port numbers for the NRUE<->Proxy
2. Fixed the send to function in the NR UE
(Previously only sending buffer not buffer+msg_type)
3. Updated pack/unpack of the SSB PDU (new RSRB field added)
4. Fixed several NR logs
5. Opening socket with NRUE<->Proxy AFTER receving RRC
measurement request from the LTE UE
This commit also removed MAX_NUM_NEIGH_CELLs and
replaced it with MAX_GNB_CELLS. This was a minor change
OAI added. The standalone sockets for the NR UE correctly
connect to the proxy. We are currently receiving dl_tti
messages from the proxy.
Also enabled X2 when we are not using the EPC
Added in the case statement for handling the
dl_dcch_msg from the NR UE. Also added in the
proper decoding of that dl_dcch_msg and freeing
