Robert Schmidt af89a6b780 Configurable Default Scheduler DL Algo 2020-07-20 09:13:19 +02:00
Robert Schmidt fe7236d9c4 Add Maximum Throughput scheduler, wbCqi 
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.
 2020-07-20 09:13:19 +02:00
Robert Schmidt 2de57fbc36 Add Proportional Fair scheduler, wbCqi 
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).

Robert Schmidt 8c7d94133f Bugfix RR DL: a retx UE might not be allocated again 2020-07-20 09:13:19 +02:00
Robert Schmidt 864fa84ba8 Default SCHED RR algo: optimize algo and defer RB calc. 
- 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.

Robert Schmidt 82194319cf Bugfix DLSCH: only warn when retx with less RB 
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.

Robert Schmidt d47c539dda S1AP: Only register MME if we do not know it yet 2020-07-20 09:13:18 +02:00
Robert Schmidt 64f0b7e0e5 Do not check for register_enb_pending 
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.
