Known Limitations, Issues and Workarounds
System Limitations
^^^^^^^^^^^^^^^^^^
-- Current code contains support for below configuration:
+- Current code contains support only for below configuration:
- Duplex mode = FDD
+ - [TDD] [Mu1] [100MHz]
+ - [FDD] [Mu0] [ 20MHz]
+ - Freuency Range = FR 1
+ - DL/UL Modulation = QPSK
- Freuency Range = FR 1
+- Current code is locally tested to support upto three UEs.
- numerology = 0
+- NR-MAC supports Round Robin scheduling currently, however the framework provides support to plug-in any other scheduling algorthim easily.
- bandwidth = 20 MHz
+- Cell broadcast is for SSB and SIB1 only.
- DL/UL Modulation = QPSK
+- FAPI files not in-line with SCF FAPI 222.10.02.
+ O-DU High currently compatible with FAPI files provided by Intel.
- single HARQ transmission
+- Implementation of F1 reset is limited to intializing UE contexts.
- single UE.
+- E2 interface is limited to KPM service model.
-- This release implements a basic scheduler with fixed scheduling for single UE.
+- On the F1-U interface, UE, RB and tunnel configurations are static.
-- Cell broadcast is for SSB and SIB1 only.
+- Cell configuration is supported by CM on O1 interface. All other configurations are static.
-- FAPI files not in-line with SCF FAPI 1.0.5.
- O-DU High currently compatible with FAPI files provided by Intel.
+- O-DU High has not been integrated with O-CU.(Using Radisys commercial CU as a test fixture)
-- Implementation of F1 reset is limited to intializing UE contexts.
+- Netconf TLS connection is not supported
-- E2 interface is limited to Traffic Steering Usecase.
+- Current code supports two Network Slices, One Default and other one Dedicated Slice.
-- 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.
+- We have to manually download the 3GPP yang models and install.
-- On the F1-U interface, UE, RB and tunnel configurations are static.
+- Currently, only two Radio resource utilization related KPIs are calculated.
+ - DL Total PRB Usage.
+ - UL Total PRB Usage.
+
+- Multi UE scheduling per TTI is supported up to 2 UEs as of now.
-- System runs on preconfigured values due to absence of CM support on O1 interface.
+- Currently, only DL supports multi-UE scheduling. UL supports single-UE scheduling per TTI
-- O-DU High has not been integrated with O-DU Low and O-CU.
Known Issues
^^^^^^^^^^^^^
-None
+
+- PDSCH DMRS must not be interleaved with PDSCH allocations.
+
+- PUSCH DMRS must not be interleaved with PUSCH allocations.
+
+- Frequency domain allocation in DCI is a bit map where:
+
+ - As per spec : the most significant bit corresponds to the group of lowest frequency.
+ - As per L1 : the least significant bit corresponds to the lowest frequency group.
+
+- Only Resource allocation type 1 (i.e RB allocation using Start RB and Number of RBs) is supported for PDSCH.
+
+- Only mapping type = 1 (i.e. Type A) supported for PDSCH.
+
+- L1 unable to process SIB1 with hardware accelerator enabled.
