Integration 2020 wk50 

MR969: Develop oriecpriupdates  
Makes IF5 functionality compatible with ECPRI user-plane. 
Control-plane functionality for supporting third-party RRUs : provides an interface converting OAI-native RF parameters, a subset of LTE framing parameters, and RF streaming activation/deactivation to a wrapper (libthirdparty_transpro.so) which uses the proprietary interface of the RRU. 
This branch was tested with a commercial eCPRI RRU from AW2S.

MR980: Nr ul scheduler basis 
- cleanup of UL scheduler, and add interface preprocessor-postprocessor (in `NR_UE_sched_ctrl_t`)
- Postprocessor can (almost) handle multiple UEs. Preprocessor will follow soon (proportional fair scheduler)
- Preprocessor for phytest (always schedule 50 RBs due to OAI UE limitations) and real UE (as many resources as possible)
- Internal structures have been updated: the `UL_tti_req` structure became an array (as `UL_tti_req_ahead`) so that we can schedule in advance and mark resources as used. Before, we would keep the corresponding nfapi message structure per UE, which could get messy when we have many UEs.

There are no functional changes (UL/DL performance is the same). 

MR987: Nr phy mac if multi ue  
- Handles multiple UEs in `NR_IF_interface.c`
- Some minor clean up

MR979: Pusch decoder threads parameter  
- Added a config file parameter for specifying the number of threads to be used for PUSCH decoding.

MR982: nr pdcp: use pdcp config
-There was a problem with SN size. It was hardcoded to 12 bits (so max sn = 4095) but we configure the UE with 18 bits. 
Get the correct value from pdcp_Config.
- Store also discard_timer and t_reordering that will be used later by a proper NR PDCP layer 

MR984: NR FR2 SSB
- several fixes mainly concerning FR2 synchronization and RA both at gNB and UE
- SSB RRC signaling for FR2
- Coreset RRC for FR2
- SSB detection in FR2 for SSB index > 15
- Adjust sync function issue
- Fix for scheduling of MSG2 (issue with sl_ahead)

# Scheduler
The scheduler is called by the chain: nr_ul_indication()=>gNB_dlsch_ulsch_scheduler()
The main scheduler function is called by the chain: nr_ul_indication()=>gNB_dlsch_ulsch_scheduler()
It calls sub functions to process each physical channel (rach, ...)
The scheduler uses and internal map of used RB: vrb_map and vrb_map_UL, so each specific channel scheduler can see the already filled RB in each subframe (the function gNB_dlsch_ulsch_scheduler() clears these two arrays when it starts)
......@@ -153,16 +154,71 @@ it sends a iiti message to activate the thread for RRC, the answer will be async
Calls schedule_nr_mib() that calls mac_rrc_nr_data_req() to fill MIB,
Calls each channel allocation: schedule SI, schedule_ul, schedule_dl, ...
this is a major entry for "phy-test" mode: in this mode, the allocation is fixed

nr_schedule_ue_spec() is called
* calls nr_simple_dlsch_preprocessor()=> mac_rlc_status_ind() mac_rlc_status_ind() locks and checks directly inside rlc data the quantity of waiting data. So, the scheduler can allocate RBs
* calls nr_update_pucch_scheduling()
* get_pdsch_to_harq_feedback() to schedule retransmission in DL
Calls nr_fill_nfapi_dl_pdu() to actually populate what should be done by the lower layers to make the Tx subframe
Calls schedule_nr_prach() which schedules the (fixed) PRACH region one frame in
advance.
Calls nr_csi_meas_reporting() to check when to schedule CSI in PUCCH.
Calls nr_schedule_RA(): checks RA process 0's state. Schedules Msg.2 via
nr_generate_Msg2() if an RA process is ongoing, and pre-allocates the Msg. 3
for PUSCH as well.
Calls nr_schedule_ulsch(): It is divided into the "preprocessor" and the
"postprocessor": the first makes the scheduling decisions, the second fills
nFAPI structures to indicate to the PHY what it is supposed to do. To signal
which users have how many resources, the preprocessor populates the
NR_sched_pusch_t (for values changing every TTI, e.g., frequency domain
allocation) and NR_sched_pusch_save_t (for values changing less frequently, at
least in FR1 [to my understanding], e.g., DMRS fields when the time domain
allocation stays between TTIs) structures. Furthermore, the preprocessor is an
exchangeable module that might schedule differently, e.g., one user for
phytest, multiple users in FR1, or maybe FR2: phytest is in
nr_ul_preprocessor_phytest(), for FR1 is nr_simple_ulsch_preprocessor() [under
development], for FR2 does not exist yet.
* calls preprocessor via pre_processor_ul(): the preprocessor is responsible
for allocating CCEs (using allocate_nr_CCEs()). Note that we do not yet have
scheduling requests or buffer status reports, and only one UE. E.g.,
nr_simple_ulsch_preprocessor():
1) check whether the current frame/slot plus K2 is an UL slot, and return if
not.
2) Find first free start RB in vrb_map_UL, and as many free consecutive RBs
as possible.
3) allocate a CCE for the UE (and return if it is not possible)
4) Calculate DMRS stuff (nr_save_pusch_fields()) and the TBS.
5) Mark used resources in vrb_map_UL.
* loop through all users: get a free HARQ PID using select_ul_harq_pid() and
update statistics. Fill nFAPI structures directly for PUSCH, and call
config_uldci() and fill_dci_pdu_rel15() for DCI filling and PDCCH messages.
Calls nr_schedule_ue_spec(). It is divided into the "preprocessor" and the
"postprocessor": the first makes the scheduling decisions, the second fills
nFAPI structures to indicate to the PHY what it is supposed to do. To signal
which users have how many resources, the preprocessor populates the
NR_UE_sched_ctrl_t structure of affected users. In particular, the field rbSize
decides whether a user is to be allocated. Furthermore, the preprocessor is an
exchangeable module that might schedule differently, e.g., one user for
phytest, multiple users in FR1, or maybe FR2: phytest is in
nr_preprocessor_phytest(), for FR1 is nr_simple_dlsch_preprocessor() [under
development], for FR2 does not exist yet.
* calls preprocessor via pre_processor_dl(): the preprocessor is responsible
for allocating CCEs and PUCCH (using allocate_nr_CCEs() and
nr_acknack_scheduling()) and deciding on the frequency/time domain
allocation. E.g., nr_simple_dlsch_preprocessor():
1) mac_rlc_status_ind() locks and checks directly inside rlc data the
quantity of waiting data.
2) return from the preprocessor if there is no data and no timing advance to
send,
3) otherwise, allocate a CCE for the UE (and return if it is not possible)
4) find a PUCCH occasion for HARQ
5a) check if there is a retransmission: if yes, find free resources to
transmit using the same resources, else
5b) calculate the necessary RBs needed to get a TBS large enough to hold all
data, or until no more resources are available
6) Mark taken resources in the vrb_map
* loop through all users: check if a new TA is necessary. Then, if a user has
allocated resources, compute its TBS, and fill nFAPI structures
(nr_fill_nfapi_dl_pdu() to populate what should be done by the lower layers
to make the Tx subframe). Update statistics (round, sent bytes).
