This change allows multiple UEs to have a tunnel interface
brought up when connecting to the 5GCN
Also, adding two new config files for mutltiple UEs
to connect to the 5GCN
The nr_rrc_ue_process_RadioBearerConfig() function
call in the RRC layer of the NRUE was removed when
it should not have been for NSA mode. This is now
added back in for NSA mode. Also, the call to
pdcp_run should only be when were NOT in NOS1 mode
and ARE in SA mode. This was fixed as well.
Ue-to-Ue IP traffic in NSA works, but eventually
the NSA UE will crash due to an incorrect PDCCH
configuration. This is a bug we will need to look
into. It doesnt always crash, only about 40% of
the time. And even when the NRUE does crash, it
happens towards the end of the simulation.
The following was changed in this commit:
- A new struct in the mac instance was created
for all emulated L1 fields.
- NR UE RRC state bug was fixed
- Checking the RAR rnti based on the MAC instance
ra.ra_rnti and not hardcoding to 0x10b
- Modified the name of the new emulate_l2 flag
to make sense: emulate_l1
Also, this commit changes the len argument in the
pusharray32 to match the actual field type (uint16_t).
There is also simple name change from sf -> slot.
The new queueing system is not a permanent solution.
It was simply a way for us to try to handle late
dl_tti_requests. If we queue every single ul_tti_req
that we get, the queue gets full very quickly becasue
we only remove ul_ttis from the queue when a uci has
been populated with a matching sfn/sf. Because of this,
we only queue ul_ttis if we have a uci_indication
prepared already. Rarely, a dl_tti_req will arrive at
the NRUE too late, and the NRUE does not have time
to create the uci_ind so we dont process the corresponding
ul_tti. A seprate queue was made to hold all other ul_ttis
the arrive in the NRUE (this queue will continuously
get full and then emptied) but will occasionally hold
a ul_tti that corresponds to a uci that hasnt
been populated yet.
