into info rather than warning to allow strict
warning/error checking in tests.

Andre Puschmann eea6f0f11b enb: fix potential invalid access in stdout metrics
this fixes a potential access of invalid PHY or MAC metrics by checking
the user entry actually exists.

Ismael Gomez ae1092257f Fix issue in 15 PRB 2CA: Due to DCI format ambiguity, the scheduler needs to use Format1A instead of Format1. The number of PRB was incorrectly calculated when generating the grant, leading to corruptions in the MAC PDU. 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

Francisco 94efeab672 Optimization of sched_ue methods to derive required number of prbs to allocate to a rnti
This optimization has been achieved by:
- implementation of "false position method" root-finding algorithm
- application of the false position method in cc_sched_ue::get_required_prb_dl/ul(...)

The number of iterations in the worst case scenario, reduced from 100 to 5 with
the proposed algorithm.
