An NR-capable UE will transmit some NR measurements.
Once received, the whole process on nr-cell addition is started.
It will fail quickly.
Many things are still missing.
What is not handled properly with this commit:
- in x2ap_eNB_handle_sgNB_add_req we hardcode the gNB ID
- nr triggering is done if we receive a measurement but this measurement is
not analyzed at all
- no timers (T_dc_overall, T_dc_prep) and as is the code fails and then the
next triggering after UE reconnection will not work (x2 ID are not well
handled here and there in the code)
Note also that the gNB part has not been looked at all for this commit.
This is work in progress...
- configure_fapi_dl_pdu is handling the nfapi_nr_dl_config_request_pdu
- while configure_fapi_dl_Tx is now handling the nfapi_tx_request_pdu
this was necessary because the computation of the TBS size is needed in the phytest scheduler
before even knowing if there is any data to transmit. The tx_request_pdu must be handled instead
only when there is data to transmit.
The timer code used to trigger periodic statistics message sending used
ITTI. Together with a high frequency reporting (e.g. 1ms), this resulted
in high CPU usage. This commit reimplements this:
* using a thread that is synchronized to the RU (if there is no MAC, we
assume there is no RU generating a tick so we create the tick source
ourselves)
* no RB trees but plain arrays
* smaller interface for users
* slight user interface changes
* remove stopped timer state: such timer might be simply removed
* remove one-shot timers
* only set up timer for sending requests
* simplify interface for timer setup
* on timer expiry, do not pass through stats request function but
directly send the reply
* Remove whatever report structure and use stats request directly for
inferring the data to send
-New MAC SDU integrity check in ue_procedures .c introduced for MCH channels.
-This SDU behavior didn’t show up with former develop
-TOCHECK whether NFAPI was properly merged on the eNB side.
-eNB_scheduler_mch has been slightly rearranged.
*BUGFIX:
-In dlsch_demodulation.c “ rxF_comp_d.m” was continuously being written to disk
*New reference config file added (lte-fdd-mbms-basic-sim.conf) for rfsim environment
