Ismael Gomez f9a02299f9 Use MAC PDU pointer instead of tti_rx and rnti as a key to associate buffers. Decouple crc_info() and push_pdu() functions. This allows for different timing architectures in the PHY 2020-12-16 13:49:29 +01:00

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 2020-12-12 15:59:27 +01:00
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

Fix the way the RLC header is accounted for depending on the bearer id.
For instance, the SRB0 does not require any RLC header.

Francisco Paisana 44a9ad76f1 avoid sched_ue dangling pointer
With the sched feature that allows scheduling in TTIs
ahead of time, there is no guarantee that when
the tti arrives to generate a sched result, the stored
raw sched_ue pointers are still valid. For this reason,
I now store the rnti and check if the rnti still exists.

Francisco Paisana a761762ec8 extended cc_sched_ue fsm to account for more harmonious transition of an scell to deactivated state 2020-10-12 14:45:13 +01:00
Francisco Paisana eafc003671 Altered the way the generation of the scheduling decision for a given
TTI is made. Instead of generating one CC in each dl_sched()/ul_sched()
call, all CC decisions are generated at once. This avoids race
conditions with calls from the RRC to the MAC to configure UEs.
