INDICATION OF SIDELINK PROCESS FOR SIDELINK FEEDBACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18523865 titled 'INDICATION OF SIDELINK PROCESS FOR SIDELINK FEEDBACK
Simplified Explanation
The patent application describes a system for indicating sidelink processes for sidelink feedback, where a second user equipment (UE) can request HARQ responses from a first UE for a specific set of sidelink processes over a physical sidelink feedback channel. The second UE can indicate multiple sidelink processes by specifying a window of sidelink processes in sidelink control information, allowing for efficient data transmission and feedback reception.
- Sidelink feedback system for HARQ responses
- Second UE requests feedback for specific sidelink processes
- Window of sidelink processes indicated in control information
- Sliding window approach for data transmission and feedback reception
- First UE and second UE coordinate to select processes for feedback

- Unanswered Questions
- How does this technology impact the overall latency of sidelink communication systems?
The patent application focuses on the efficiency of indicating sidelink processes for feedback, but it does not delve into the potential impact on latency in real-world implementations. Further research or testing may be needed to assess the latency implications of this approach.
- What are the potential security considerations when coordinating sidelink processes for feedback between UEs?
While the patent application describes the coordination of sidelink processes for feedback, it does not address potential security vulnerabilities or considerations in this process. Exploring the security implications of such coordination could be crucial for ensuring the integrity of data exchange in sidelink communication systems.
Original Abstract Submitted
This disclosure provides systems, methods and apparatuses for indicating sidelink processes for sidelink feedback. A second user equipment (UE) may request hybrid automatic repeat request (HARQ) responses from a first UE for a particular set of sidelink processes over a physical sidelink feedback channel. To indicate multiple sidelink processes, the second UE may indicate, in sidelink control information, a window of sidelink processes. The window may be a sliding window that starts with a starting sidelink process and extends through other sidelink processes. The second UE may transmit data for the sidelink processes in the sliding window and receive feedback for the indicated sidelink processes. In some aspects, the first UE may select, in coordination with the second UE, the sidelink processes for which feedback is to be provided.
