An open radio access network (O-RAN) may include a control unit that communicates with a core network, a distributed unit that communicates with the control unit, a radio unit that communicates with the distributed unit and a user equipment (UE). Currently, the O-RAN may lack support for static configuration for a physical uplink shared channel (PUSCH) communication of message-A in a third generation partnership project (3GPP) two-step random access procedure. Hence, according to some aspects of the disclosure, the distributed unit may receive, from a radio unit, a static configuration support indication for receiving payload data via a message in a two-step random access procedure, the message including a preamble and the payload data. The distributed unit may further transmit, in response to receiving the static configuration support indication, static configuration information to the radio unit, the static configuration information for receiving the payload data communicated via the message.
