At the moment, the NSA mode worked once, but shows
unpredictable behavior. Other times it does not work.
In this commit I added several LOG_A messages for NSA
mode. Also removed old comments that were added during
development. Lastly, more comments for all the hacks
have been added.
The eNB may only check for RRC_Complete in EPC
mode. Need to look at this further. Updated how
we pass the RRC_Complete msg from NR UE to LTE UE.
Need to still handle transaction_id from dl_dcch_msg
in the LTE UE and trans_id from nr_dl_msg.
However, the NR UE is crashing because it is receiving
a second RRCReconfig message from the LTE UE and it is
having trouble decoding it. Need to understand this.
Also removed several warnings by properly
declaring nr-nFAPI functions and removed
declaration of unused functions. Also, reverted
eNB configuration file changes.
This caused the SCTP descriptor to be reset. This
made issues in the X2 interface between gNB and eNB.
Lots of logs added here. Need to fill NR_UE_Capability_Info
properly.
Now, we are able to fill the UE_Capability_Info that
the LTE UE and eNB are expecting. We then are able to
generate a RRC_DCCH_DATA_COPY_IND to trigger the
processing of the UE_Capability_Info (and sending the
info to the eNB). The info being received at eNB has not
been tested yet.
Also some code clean up.
Also removed the [eNB_index + 1] saving/writing
in the process_MeasObj function. This indexing
was incorrect. Also cleaned up the code, fixed
ssRSRB -> ssbRSRP. Lastly, added assertFatals
around indexing in process_measObj function.
Added check and logs. If we change ind = 1 it
crashes the LTE UE so we log for now. Also cleaned
up a lot of the code. Lastly, we set freed vars to NULL.
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
