The test seemingly ensures that this code block is hit only once.
However, if we enable later activation of MMEs, it will be hit a second
(and third, ...) time. The only thing in guards against, though, is an
INIT message to the L1L2 thread, when register_enb_pending == 0, which
should only be sent once. Therefore, functionality won't be changed if
register_enb_pending becomes negative, and the assert can be removed.
- UE context status enters RRC_NR_NSA_RECONFIGURED state, after the eNB receives an RRCConnectionReconfigurationComplete message including the
scg_ConfigResponseNR_r15 container.
- Use this state to avoid triggering sGNB Addition Request multiple times
- 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
- IP data were fetched and passed to MAC directly at the PHY layer
- random data was generated whenever there's no upcoming data.
- Therefore these functionalities are now moved to MAC and FAPI interfaces
- are used instead.
- ceiling computation num of segments (cod/dec)
- fixes demodulation
- initialisation CW for PDSCH RA
- memcpy dl_ch_estimates to pdsch_vars_ra (hotfix)
- correct N_RB for DCI 1_0 and RNTI_RA
- LDPC decoder does not support lower MCS, therefore MCS 9 has been selected
for the Msg2 configuration.
- This is done only in do-ra mode, in order to prevent any fallout on the
current the configuration used for the operation with the commercial UE
hack: in schedule_ue_spec, 3 bytes are "reserved" (this should be
done better). An RLC AM entity may ask for only 2 bytes for
ACKing and get a TBS of 32 bits and due to these 3 reserved bytes we may
end up with only 1 byte left for RLC, which is not enough. This hack
prevents the problem. To be done better at some point. If the function
schedule_ue_spec is (has been) reworked, this hack can be removed.
Dig for "TBS - ta_len - header_length_total - sdu_length_total - 3"
in schedule_ue_spec.
This should be done better at some point.
