Presented are systems and methods for model management. A wireless communication node can determine a configured set of at least one field of a downlink control information (DCI) signaling, that is to be shared by a plurality of transmissions, the plurality of transmissions scheduled by the DCI signaling on a plurality of component carriers (CCs). The wireless communication node can send an indication of one or more fields from the configured set to a wireless communication device via a dynamic signaling.
