Selects the UE with the highest CQI. If two UEs have the same CQI,
choses the one with highest number of bytes in RLC queue. Allocates as
many RBGs as possible, and potentially continues with the next UE.
Selects UE with highest coefficient. Allocates until there are no more
RBGs to allocate, or UE has no more data. In the latter case, continues
with the next UE (second-highest coefficient).
- Loop only to next UE instead of jumping multiple
- mark used RBGs in rbg_mask
- Only calculate number of RBs based on CQI when UE is selected, instead
of calculating for all UEs which might be unnecessary.
- When looping the list of UEs for RB allocation, remove UEs that have
no data anymore instead of skipping them.
The preprocessor pre-allocates a CCE. Thus, when arriving at the check
for the number of RBs for retransmission, it is too late to skip the UE.
Therefore, only print a warning.
The default schedulers allocate a correct amount of RBs for
retransmissions, therefore it is ok.
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
