Francisco cba0cc457f sched rand test refactor: creation of abstract sched simulator class for testing 4 years ago
Francisco b4861bc59a move sched params and sched helper methods to sched_helpers.h/cc files. Removed place in the scheduler where the mcs is increased forcefully to avoid segmentation 4 years ago
Francisco 99f94d9a1a Bug fixes of srseNB scheduler TPC 
- fix encoding of TPC command
- use of exponential average with irregular sampling for the ULSNR average estimate.
  Turns out using a time-windowed average for the SNR was a bad idea.
  If the UL grants are very sporadic, the SNR time window will never have samples
  when a TPC is encoded
- update of TPC sched test
- other fixes in accumulators lib
