According to the disclosed aspects, indications of DFI presence in downlink control information (DCI) messaging are provided that limit any increase to DCI overhead for uplink grants. In a first aspect, DFI presence may be signaled using unused or disallowed DCI variable states for indication of DFI presence. In another aspect, a separate bit may be added to a DCI message for indicating DFI presence. Additional aspects include repurposing DCI fields which are specific to cell radio network temporary identifier (C-RNTI)-based uplink grants, or may defining a new RNTI (e.g., DFI-RNTI) for indicating DFI presence. Further aspects may provide for radio resource control (RRC) signaling that configures which DCI variable state can be used to indicate DFI presence."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Downlink feedback information signaling enhancements","description":"Enhancements to downlink feedback information (DFI) signaling is disclosed.
