General Information

O-RAN Distributed Unit Low Layers (O-DU LOW)
PTL	Zhimin Yuan
Summary	Focus on L1 functional development according to O-RAN WGs and 3GPP specification.
Project	o-du, o-du/l2, o-du/phy

Quick Explore:

The project include two parts contributions:

part 1: O-RAN FH interface lib, FAPI TM lib and WLS lib. O-RAN FH interface lib which follow O-RAN WG4 interface to implement O-RAN radio interface from DU end, WLS and FAPI TM is the interface implementation between O-DU low and O-DU High.

part 2: L1 binary along with one set of uses cases which were performed with test MAC application.

With above parts, below O-RAN network functions can be verified with different data flow to meet your different purpose:

data flow 1: FH lib UT, FH lib had it's own test framework, which includes one test app to simulator the l1 and test RU to simulator the RU, between test app and test RU, data was exchanged follow O-RAN WG4 C/U/S plane spec. there are multiple use cases that are defined with variant numerology and bandwidth.
data flow 2: RRU interface UT, the test app and FH lib can also be used to test real RRU with simulated L1 data connecting to SA/SG
data flow 3: testmac timer: L1 binary and test mac timer mode was provided to verify the FAPI interface with full L1 functionalities , it also can be used to verify
data flow 4: testmac radio:
data flow 5: E2E open source
