1. A method for wireless communications at a remote unit of a base station, comprising:
reporting, from the remote unit to a distributed unit of the base station, a message indicating that the remote unit supports a remote unit processing capability that is one of a first processing capability or a second processing capability, wherein the first processing capability corresponds to additional physical layer signal processing at the remote unit than does the second processing capability;
processing one or more signals in accordance with the remote unit processing capability included in the message transmitted to the distributed unit, the processing resulting in one or more processed signals, wherein at least a first portion of the one or more processed signals results from processing of uplink signals of the one or more signals; and
forwarding the first portion of the one or more processed signals as corresponding one or more processed uplink signals from the remote unit to the distributed unit via an application programming interface that supports both the first processing capability and the second processing capability.
