Francisco a5ef9f1eb9 potential fix for heap-overflow in scheduler, issue #2053. Added a bound check for the number RACH handled per tti. RACHs are ignored once the limit is surpassed. 2020-12-12 15:59:25 +01:00

Francisco 8d181ef41c Optimization of cc_sched_ue::cqi_to_tbs(...) method via the use of root-finding algorithm 2020-12-12 15:59:25 +01:00
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.

Francisco 2dc3fce9bd fix derivation of UL-64QAM support from the UE Capabilities in the eNB 
Before this PR, the eNB was not activating UL-64QAM if the UE release was below 12,
due to an erroneous convertion of the ASN1 EUTRA Capabilities struct into the flattened
srslte::ue_capabilities_t.

With this PR, the eNB activates UL-64QAM for the following cases:
- UE category 5
- UE category 8 and release >= 10
- UE category UL 8 and release >= 12

Francisco f07e52129c increase mcs ul upper bound to 24 when ue is cat4 and enb supports 64qam. Simplified max_mcs computation 2020-12-12 15:59:25 +01:00
Francisco 3d80ff4831 fix activation of PDCCH for adaptive retxs. 2020-12-12 15:59:25 +01:00
Francisco fc81a5c6ba harq ack state can now only be NACK or ACK. The ul_harq pending phich flag is now reset after phich scheduling. Thus, the existence of a crc_info(...) signal from the PHY is not required. 2020-12-12 15:59:25 +01:00

Andre Puschmann 6d3af2d2bd rlc_um: fix bearer name in logging after re-configuration 
the RLC bearer name was empty after reestablishing a UM bearer.

we need to pass the RLF config and RB name to the internal configure()
call of the Rx entity, like we already do for the Tx side

Andre Puschmann d014a89cfb pdsch_ue: enable EVM measurements for PDSCH 
enable EVM measurements by default and print them in to stdout.
This is very useful for manual receiver calibration with the
PDSCH eNB example.

Andre Puschmann 504d8fd9f0 pdsch: calculate average PDSCH EVM over all decoded codewords 
when EVM measurements are enabled, instead of only logging them for
each decoded codeword, we also calculate the average.

this is useful for calibration.
