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.
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.
At the moment, the NSA mode worked once, but shows
unpredictable behavior. Other times it does not work.
In this commit I added several LOG_A messages for NSA
mode. Also removed old comments that were added during
development. Lastly, more comments for all the hacks
have been added.
Also removed the [eNB_index + 1] saving/writing
in the process_MeasObj function. This indexing
was incorrect. Also cleaned up the code, fixed
ssRSRB -> ssbRSRP. Lastly, added assertFatals
around indexing in process_measObj function.
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
This commit also removed MAX_NUM_NEIGH_CELLs and
replaced it with MAX_GNB_CELLS. This was a minor change
OAI added. The standalone sockets for the NR UE correctly
connect to the proxy. We are currently receiving dl_tti
messages from the proxy.
- enhancement of DL indication flow for Msg2 (RAR)
- merging interface procedures to handle DLSCH and RAR together
- better separation of MAC and PHY functionalities
- cleanup of double ambiguous functions to process RAR
- merging functions to process TA command into the ue_ta_procedures function
- enhancement of logging and formatting in the process
- redundant code for the configuration of the scheduled_response was removed
- scheduled response is not needed to be stored in the NR_UE_MAC_INST struct as it passed to the function right away
- calling nr_ue_scheduled_response after pdu preparation
- increasing the number_pdus before response scheduling
- resetting after dl/ul config pdu handling
- replaced nr_slot_t with int as it was barely used in the code (also is defined after an lte struct)
- removed use of phy_frame_config_nr from the UE (another file was created in SCHED_NR_UE, still the
gNB file is used in some tests file at UE side)
- Msg2 scheduler used for testing purposes was removed
- Now the UE tries to DCI 1_0 scrambled with RA_RNTI in the RA window
- If no RAPID is found within the RA window, instructs PHY to TX PRACH
