Abstract
Example methods and apparatus disclosed herein use the 'processing margin' at a radio unit (RU) () as a control variable for modifying the allocation of virtualized processing resources used by a digital unit (DU) () that supports the RU (). The DU () and RU () form a radio processing chain with a functional split, in which the DU () performs certain processing operations and provides corresponding processed data to the RU (), which performs further processing for the generation and transmission of the corresponding radio signals. The “slack” between the end of processing in the RU () and the corresponding required transmission time represents the processing margin. The processing-margin feedback loop allows for the virtualization of all or part the DU (), while avoiding the need for the network operator to implement or pay for over-dimensioning of the DU (), as would be needed to ensure that a static resource allocation meets worst-case processing needs.
