1. A method for wireless communication at a radio unit of a wireless communications system, comprising:
identifying configuration information that includes a first set of functions to be performed at the radio unit, wherein the radio unit has a capability to perform radio frequency functions, baseband functions, medium access control functions, or any combinations thereof, and the first set of functions includes at least one radio frequency function;
configuring the first set of functions at the radio unit based at least in part on the identifying, wherein the first set of functions includes a first set of downlink functions and a first set of uplink functions;
receiving, from a central unit or a distributed unit that performs a second set of functions including at least one medium access control function, downlink signals that are to be processed according to the first set of downlink functions;
processing the downlink signals according to the first set of downlink functions to generate a downlink communication;
transmitting the downlink communication to at least one user equipment (UE);
receiving radio frequency signals from the UE in a set of wireless resources associated with an uplink allocation granted to the UE for an uplink communication;
processing the received radio frequency signals according to the first set of uplink functions to generate processed uplink signals; and
providing the processed uplink signals to the central unit or the distributed unit to be processed according to the second set of functions.
