This commit includes about 1/3 of the code clean up
in preparation for the merge to the OAI develop
branch. Several of the changes are white space changes,
removing of logs, comment removals, and updating any
changed code for our use-case to be clear for NSA mode.
In this commit, we create a new flag in the MAC
instance which is set to true if the recevied
DL DCI PDU's RNTI value matches the current UEs
RNTI value. If the RNTI value does not match,
then we should not process the recevied tx_request.
This check should only take place after the CFRA
procedure is complete.
The harq_pid is set to inactive during the scheduling
of ACK/NACK, but this is happening before tx_req (PDSCH)
is recevied. We update the global harq_pid then use it
once we get the PDSCH PDU, then we set it to inactive.
Also, the global previously wasnt being set properly because
a memset was changing the def_dci_re15 struct. We now
memset after we update the harq_pid global.
In this commit we have updated the NRUE
to properly get the RadioBearer info from
the gNB. Because NSA and SA mode both use
this information, we have updated the SA
function previously in place by changing
the name to allow both NSA and SA mode to
use. This commit also updated the NR/LTE UEs
configuration files to with the correct
proxy IP address.
1. Changed hard coded preamble index(63) to soft coded.
2. Active UE will not be considered in gNB scheduging RA.
3. Added condition to process dci indication to handle multiple UEs.
4. Bug fix in mutex_lock (unlock to lock). It should be lock rather than unlock.
5. nr_ue_scheduler update not to entering into getting IP traffic to be transmitted in noS1 mode.
6. log update in checking the number of rx_ind or crc
Also, we only should be handling/generating AM
PDUs in the PDCP/RLC layer, not UM PDUs. Updated
the pre-configuration settings. This seemed to
make the uplink traffic work (meaning it gets
from NR UE to the gNB to the EPC). Woo! Still
working on the downlink.
Previously, we would assume every downlink in
slot 7 was an RAR; now we assume every slot 7
that occurs before the CFRA procedure is done
is an RAR. Also changed the logic in scheduler
to allow us to get nr_ue_sdus in the MAC layer.
