- Hardcoding the freq_index when filling RACH
- Not handling DCI unless dci_rel_15 global is allocated
- Verifies ra_rnti matches in prach pdu and RACH
- Updates handling of DCI and RX from dl and tx reqs
The fix added in this commit may not be correct and
should be reviewed by Eurecom. For now we set the
future frame based on the PRACH recevied frame + 1.
Also fixed the copying of RACH ind into UL_INFO global.
RAR is being passed to NR UE.
Also fixed a few bugs in nr-nFAPI:
- Push16->push8 fix in packing of RACH
- Allocating memory for pdu_list and preamble_list in unpack
- Properly indexing through both lists during unpack
- Created new nr_rach handling function
Several other changes in this commit include:
- Setting the number of PDUS in the ul_config
to be zero when we will it (inside of the
get_ul_config() function.)
- We reset the nprach flag to 0 for each slot.
- We return out of the prach scheduler if
mac->ul_config == NULL
- Added error checking for array indexing
- Created a dummy scheduler response function.
- Allocated ul_config_req initially
Also calling the new L1_nsa_prach_procedures()
function after using the nr_ue_scheduler. Added
some error checking in the nr_ue_scheduler. Added
some error checking in the process_nsa_msg in both
the NR and LTE UE
Seems to be working at the moment but
may need to add more info in the rach_ind.
Also, need to verify gNB is getting the
rach_ind and starting RA procedure.
Had to hack the code to schedule the prach.
Need to verify this is ok because ul_config = NULL.
Also had to change logic for calling fill_schedule_response.
However, we are not properly calling the
nr_ue_get_rach() function. The RA is being
properly initialized. In the nr_ue_get_rach()
the pRACH is not scheduled. Tried to add in
the scheduling of this, but it crashes here.
The other changes include revering the
nr_ue_get_rach() changes from previous commit.
Also, changed a few log levels and reverted
a previous change in the NR UE RRC layer that
was incorrect.
Several places where memory ownership was changed
and the original owner was not set to NULL. Also,
the transaction_identifier is now based on the
received dl_dcch_msg in the LTE UE. Still need to
fix the t_id for the NR UE. Also added comments for
RACH procedure in NR UE.
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
