INDICATION OF SIDELINK PROCESS FOR SIDELINK FEEDBACK - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240179711 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 data transmission and feedback reception within this window.

• Explanation of the patent:
• System for indicating sidelink processes for feedback
• Second UE requests HARQ responses from first UE for specific sidelink processes
• Window of sidelink processes indicated in control information
• Sliding window approach for data transmission and feedback reception
• First UE can select sidelink processes for feedback in coordination with second UE

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.
