DOWNLINK FEEDBACK INFORMATION SIGNALING ENHANCEMENTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18614381 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 increasing DCI overhead.
- DFI presence may 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: - 5G and future wireless communication systems - Network optimization and resource allocation - Improving spectral efficiency and overall system performance
Problems Solved: - Minimizing DCI overhead in uplink grants - Efficient signaling of DFI presence without additional complexity - Enhancing system capacity and throughput
Benefits: - Enhanced system performance and spectral efficiency - Improved resource allocation and network optimization - Streamlined signaling process for DFI presence
Commercial Applications: Title: Enhanced DFI Signaling for 5G Networks This technology can be utilized in: - Telecommunications companies for optimizing network performance - Equipment manufacturers for developing advanced wireless communication systems - Research institutions for further improving 5G and future wireless technologies
Questions about Enhanced DFI Signaling: 1. How does the patent application address the challenge of minimizing DCI overhead in uplink grants? 2. What are the potential implications of repurposing DCI fields for signaling DFI presence?
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.
