Sidelink HARQ Resource Reselection for Multiple Processes

The patent segments the resource management by associating each sidelink process with a specific HARQ process ID. When resource reselection is triggered, only the affected HARQ process is reselected while other HARQ processes maintain their original resources. This segmentation approach allows multiple sidelink processes to share a single selected sidelink grant while managing resources efficiently through process-specific HARQ identification.

The patent implements partial resource reselection by identifying which specific sidelink process triggered the reselection event and only reselecting resources for that particular HARQ process. Instead of performing full resource reselection for all sidelink processes, the system selectively reselects only the necessary portion, thereby maintaining communication reliability for the affected process while avoiding unnecessary time loss and overhead from reselecting all processes.

The patent enables a single selected sidelink grant to serve multiple sidelink processes by implementing multi-functionality through HARQ process IDs. Each sidelink process is uniquely identified and associated with a specific HARQ process, allowing the system to handle diverse QoS requirements (such as different priorities, latencies, and reliability needs) within a unified grant structure. This universal approach improves system adaptability while managing control complexity through standardized HARQ identification and selective reselection mechanisms.
