francescomani 2a3a27a48f fix CORESET start PRB according to standard at OAI gNB 2025-12-22 17:31:26 +01:00
francescomani c1747a8109 phy: remove unnecessary vendor extension fields 
When doing analogue beamforming, the beam ID for a pre-defined beam
table is passed directly to RU and there is no need to store the beam
table in PHY.

Robert Schmidt bae9e0f1e8 Rewrite nr_generate_dci_top() without msgTx and shorter 2025-11-14 12:25:05 +01:00
Robert Schmidt 34aa69828a Harmonize UL PDCCH PDU type for further refactoring 
Both (DL) PDCCH and UL PDCCH PDU types are fundamentally of the same
type, so correct the array's type to facilitate refactoring later (a
later commit will reuse a single "generate DCI" function for both
cases).

Optimizations of PDSCH Resource Mapping in nr_dlsch.c/nr_modulation.c

These changes add SIMD optimizations for Neon/AVX2/AVX512 in the PDSCH
transmit path. The timing improvements are listed here based on the

    nr_dlsim -e25 -R273 -b273 -s30 -x "layers" -y 4 -z 4 -P

benchmark with "layers" 2,3,4 and comparing "PHY proc tx":

Bugfix in gNB modulated DCI buffer size

Bartosz Podrygajlo 16f028dba5 Dynamic PDCCH aggregation level 
The aggregation level search order for PDCCH candidates is modified:
 - the search starts from desired_agg_level_index, which is a value from 0 to 4
   proportial to pdcch_cl_adjust.
 - pdcch_cl_adjust is a value between 0 and 1 that indicates PDCCH channel quality
   by averaging HARQ DTX rate. A value of 0 means perfect channel, a value o 1 means
   impaired channel.
