1. A method performed by a distributed unit of a radio access network node having a split architecture, the method comprising:
determining a status or error of the distributed unit;
sending, to a control unit of the radio access network node, an indication indicating the status or error of the distributed unit, the indication indicating one or both of the status or error of the distributed unit for at least one cell served by the distributed unit and at least one functionality performed by the distributed unit, the indication comprising a set of bits, the set of bits comprising one or more subparts, each of the one or more subparts being indicative of the at least one functionality of the distributed unit, an issue with the at least one functionality, and a severity of the issue, the issue with the at least one functionality being associated with at least one of a paging overload, a public warning system overload, and a system information overload; and
receiving instructions from the control unit of the radio access network node, the instructions being at least partially based on the indicated status or error.
