TECHNIQUES FOR USING MULTIPLE SYMBOLS TO PROVIDE FEEDBACK FOR A SIDELINK TRANSMISSION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17521392 titled 'TECHNIQUES FOR USING MULTIPLE SYMBOLS TO PROVIDE FEEDBACK FOR A SIDELINK TRANSMISSION
Simplified Explanation
Methods, systems, and devices are described for improving the reliability of a sidelink feedback channel in wireless communication. The innovation involves a second user equipment (UE) transmitting a sidelink message to a first UE, and the first UE providing feedback for the sidelink message via a feedback opportunity. The first UE can enhance the reliability of the feedback by performing frequency hopping or transmitting the feedback using multiple physical resource blocks (PRBs) within one symbol of the feedback opportunity, or both. The pattern for frequency hopping or PRB bundling can be defined or determined by the base station, the first UE, the second UE, or a combination of them. In some cases, the pattern may be preconfigured at the first UE, the second UE, or both.
- Second UE transmits a sidelink message to first UE

Original Abstract Submitted
Methods, systems, and devices for wireless communication are described to support increasing a sidelink feedback channel reliability. A second user equipment (UE) may transmit a sidelink message to a first UE, and the first UE may provide feedback for the sidelink message via an associated feedback opportunity. The first UE may perform frequency hopping from one symbol to another during the feedback opportunity, may transmit the feedback using multiple physical resource blocks (PRBs) within one symbol of the feedback opportunity, or both. A pattern for frequency hopping, or for the multiple PRBs, or both, may be defined or determined by a base station, the first UE, the second UE, or any combination thereof. In some cases, a pattern for frequency hopping or for PRB bundling may be defined or preconfigured at the first UE, the second UE, or both.
