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.
This commit changes the stub functionality entirely.
We are now queueing any received NR nFAPI message
and handling it only after we recevie a slot ind
that corresponds with the nFAPI message's sfn/slot
value. When doing this, an existing issue has been
brought to light. The gNB and NR UE are not in sync
when it comes to their slot indications. Generally,
the NR UE seems to be ahead of the gNB by around 6-7
slots. This commit has a hack... when we receive a
slot indication at the moment, we decrament it by 6
to try to keep the NRUE from being ahead of the gNB.
This will be fixed shortly... This was a temporary
fix..
