DOWNLINK FEEDBACK INFORMATION SIGNALING ENHANCEMENTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240313899 titled 'DOWNLINK FEEDBACK INFORMATION SIGNALING ENHANCEMENTS
The patent application discusses enhancements to downlink feedback information (DFI) signaling to limit any increase in downlink control information (DCI) overhead for uplink grants.
- Indications of DFI presence in DCI messaging are provided without adding to DCI overhead.
- DFI presence can be signaled using unused or disallowed DCI variable states.
- A separate bit may be added to a DCI message for indicating DFI presence.
- Repurposing DCI fields specific to cell radio network temporary identifier (C-RNTI) based uplink grants.
- Defining a new RNTI (e.g., DFI-RNTI) for indicating DFI presence.
- Radio resource control (RRC) signaling to configure which DCI variable state can indicate DFI presence.
Potential Applications: - Wireless communication systems - 5G networks - Mobile telecommunications
Problems Solved: - Reducing DCI overhead for uplink grants - Efficient signaling of DFI presence - Optimizing radio resource control in wireless networks
Benefits: - Improved efficiency in wireless communication systems - Enhanced performance of 5G networks - Streamlined signaling processes
Commercial Applications: Title: Enhanced DFI Signaling for Wireless Communication Systems This technology can be applied in: - Telecommunication equipment manufacturing - Network infrastructure development - Mobile network operators
Questions about Enhanced DFI Signaling: 1. How does the patent application address the issue of DCI overhead in wireless communication systems? 2. What are the potential benefits of using DFI-RNTI for indicating DFI presence in DCI messaging?
Original Abstract Submitted
enhancements to downlink feedback information (dfi) signaling is disclosed. 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.
