Bug Corrections
System Limitations
^^^^^^^^^^^^^^^^^^
-- Current code contains support for below configuration:
-
- Duplex mode = FDD
+- Current code contains support only for below configuration:
- Freuency Range = FR 1
+ - [TDD] [Mu1] [100MHz]
+ - [FDD] [Mu0] [ 20MHz]
+ - Freuency Range = FR 1
+ - DL/UL Modulation = QPSK
- numerology = 0
+- Current code is locally tested to support upto three UEs.
- bandwidth = 20 MHz
-
- DL/UL Modulation = QPSK
-
- single HARQ transmission
-
- single UE.
-
-- This release implements a basic scheduler with fixed scheduling for single UE.
+- NR-MAC supports Round Robin scheduling currently.
- Cell broadcast is for SSB and SIB1 only.
- On the F1-U interface, UE, RB and tunnel configurations are static.
-- System runs on preconfigured values due to absence of CM support on O1 interface.
+- Cell configuration is supported by CM on O1 interface. All other configurations are static.
-- O-DU High has not been integrated with O-CU.
+- O-DU High has not been integrated with O-CU.(Using Radisys commercial CU as a test fixture)
-- O-DU High O1 module has not been integrated with SMO/OAM so a Netconf CLI client is used to demo the get alarm-list flow
+- Netconf TLS connection is not supported
+
+- Current code supports two Network Slices, One Default and other one Dedicated Slice.
+
+- We have to manually download the 3GPP yang models and install.
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.
