Sidelink Feedback Channel Encoding Using Source and Destination IDs

The patent applies parameter changes by dynamically selecting different encoding and scrambling parameters based on the communication scenario (unicast, groupcast, or broadcast). The source ID, destination ID, and cell ID are used as configurable parameters that change according to the specific sidelink communication context, thereby improving reliability without requiring a completely new encoding framework.

The patent segments the sidelink feedback channel processing into distinct stages: source ID acquisition, destination ID acquisition, cell ID acquisition, SFCI generation, channel encoding, and scrambling. Each stage uses specific ID parameters independently, which simplifies the overall complexity by breaking down the complex encoding process into manageable segments that can be processed sequentially.

The patent implements preliminary action by pre-acquiring and storing source ID, destination ID, and cell ID information before the actual SFCI transmission occurs. These ID parameters are obtained in advance during the connection setup or resource allocation phase, so that when encoding and scrambling are needed, the necessary parameters are already available, reducing processing time during critical transmission moments.

The patent merges the acquisition and usage of multiple IDs into a unified processing framework. Instead of treating source ID, destination ID, and cell ID as separate processing streams, the patent combines them into a single integrated encoding and scrambling process that efficiently utilizes all three parameters simultaneously, thereby reducing overall processing time while maintaining enhanced reliability.
