However, when we free after we encode, fsanitize isnt happy.
Need to clean that up. Also, found an actual bug in LTE.
For the random value issue from fall 2020, we added a fix.
This fix uses ctxt and we were getting ctxt properly.
Lastly, we allocated some memory in processing of the
NR Meas report in the eNB.
At this point we are successfully able to build.
Additionally, we can run the scenario,
however, it does not pass. It seems that the gNB
is not connecting to the proxy correctly. Just
wanted to push the progress so far. FYI, the items
that had to be changed to correct the linking issues
were the following:
- mac_rrc_data_ind_ue vs. nr_mac_rrc_data_ind_ue
- rrc_data_req vs. nr_rrc_data_req
- mac_rrc_data_req_ue vs. nr_mac_rrc_data_req_ue
- rrc_data_req_ue vs. rrc_data_req_nr_ue
- rrc_data_req vs. nr_rrc_data_req
The listed functions should be declard in the LTE/NR
UE directory depending on the functionality. Several
were mixed. i.e.: LTE functions being called in NR UE.
Also, removing siWindowLength, siWindowLength_int,
SIBType, SIBPeriod, and siPeriod_int from the NR UE RRC.
These variable were not used in the NR UE and are defined
for LTE only.
Lastly, in the NR_IF_Module.c of the NR UE, the global
variable def_dci_pdu_rel15 is not accessible. Need to
revisit this. For not it is commented out.
At this point we can see the UDP uplink data
getting to the GTP layer of the gNB. This
only works if you change the memcpy in serialize_sdu()
to not have the encoded.byte
In the PDCP layer, if the sdu size < 3, this
just means control information is being passed.
In this case, we do not want to cipher the sdu,
its better to just return.

The IP traffic still does not work. But we are
updating the NR UE scheduler to ensure we are are
sending true IP traffic. Also, we were getting an
assert(); as well, and there was no logs, so we
fix that in this commit as well.
- Fix the SA RF test (wrong conf file)
- No more copy of RAW files in SA
- Fix no-detection of failures on RA

Also changed logic in the NR UE schedule to read
IP traffic. Also, configured the RLC layer in the
NR UE softmodem and the DRBs with the cRNTI once
the RACH procedure is complete in the NR UE.
Updated the configuration files. Added a sleep to
ensure that the LTE UE gets attached to the EPC
before the bearer is modified to be gNB. Updated
the ifconfig tunnel up command to be brought up
by the NR UE socket when in NSA mode. Lastly,
started the gNB PDCP layer in S1 mode.
1. If VNF is slower than PNF, next scheduling will be done after resync.
2. If VNF is unstable in slot progress, next scheduling will be done in next stable status.
3. SFN/SLOT indications are queued in nrUE.
4. get_queue is used instead of unquque for FIFO operation.
MR !1206 : nr_ue_remove_high_speed_flag
This flag is always set to 1,
With multiple DMRS symbols configuration, very recent DMRS containing symbol shall be for channel estimation.
MR !1205 : fix-lte-ue-modem-in-docker-container
We bind the socket to any_addr (instead of localhost), so the commands to the UE can come also from a remote machine
MR !1178 : NR_CSIRS_tomerge
Implementation of CSI RS transmission at gNB
