469 Known Limitations, Issues and Workarounds
470 -----------------------------------------
474 - Current code contains support only for below configuration:
476 - [TDD] [Mu1] [100MHz]
477 - [FDD] [Mu0] [ 20MHz]
478 - Freuency Range = FR 1
479 - DL/UL Modulation = QPSK
481 - Current code is locally tested to support upto three UEs.
483 - NR-MAC supports Round Robin scheduling currently.
485 - Cell broadcast is for SSB and SIB1 only.
487 - FAPI files not in-line with SCF FAPI 1.0.5.
488 O-DU High currently compatible with FAPI files provided by Intel.
490 - Implementation of F1 reset is limited to intializing UE contexts.
492 - E2 interface is limited to Traffic Steering Usecase.
494 - Forming of RIC event trigger definition, RIC indication header and RIC indication message is unclear in the E2AP draft spec versions. Therefore, implementation does not contain accurate values. Contents of RIC indication message are mocked and triggered just once.
496 - On the F1-U interface, UE, RB and tunnel configurations are static.
498 - Cell configuration is supported by CM on O1 interface. All other configurations are static.
500 - O-DU High has not been integrated with O-CU.(Using Radisys commercial CU as a test fixture)
502 - Netconf TLS connection is not supported
504 - Current code supports two Network Slices, One Default and other one Dedicated Slice.
506 - We have to manually download the 3GPP yang models and install.
511 - PDSCH DMRS must not be interleaved with PDSCH allocations.
513 - PUSCH DMRS must not be interleaved with PUSCH allocations.
515 - Frequency domain allocation in DCI is a bit map where:
517 - As per spec : the most significant bit corresponds to the group of lowest frequency.
518 - As per L1 : the least significant bit corresponds to the lowest frequency group.
520 - Only Resource allocation type 1 (i.e RB allocation using Start RB and Number of RBs) is supported for PDSCH.
522 - Only mapping type = 1 (i.e. Type A) supported for PDSCH.
524 - L1 unable to process SIB1 with hardware accelerator enabled.
534 O-DU High uses FAPI interface files provided by Intel and therefore, not completely in-line with SCF FAPI 1.0.5.
