Multi-Device Ranging Scheduling in NAN Discovery Windows

The patent merges multiple ranging preparation operations into a single discovery window interval by introducing a group-based mechanism. Multiple external devices are assigned to the same group, allowing the electronic device to perform ranging preparation with all devices in the group simultaneously during one discovery window, rather than sequentially across multiple windows. This combining approach directly reduces the total time while maintaining reliable operation through group coordination.

The patent applies preliminary action by performing group assignment and scheduling of ranging preparation operations before the actual ranging takes place. During the discovery window, the electronic device assigns external devices to groups and schedules their ranging preparation operations in advance. This preliminary organization enables efficient execution during the low-power state interval, reducing overall time consumption while ensuring reliable operation sequencing.

The patent introduces a new dimensional approach by utilizing the low-power state interval, which traditionally follows the discovery window, for performing ranging preparation operations. This shifts the operation timing from a single-dimensional constraint (discovery window only) to a two-dimensional time structure (discovery window for assignment + low-power state for execution). This dimensional change enables faster productivity while maintaining operational simplicity through clear phase separation.

The patent applies dynamics by making the ranging operation timing flexible rather than fixed. The system dynamically assigns devices to groups during the discovery window and then executes ranging preparation operations during the subsequent low-power state interval. This dynamic timing adaptation allows the system to optimize between simplicity and productivity based on the operational phase, improving overall ranging operation speed without complicating the user interface.

The patent implements continuity of useful action by maintaining group assignments and ranging preparation schedules across the transition from discovery window to low-power state interval. Instead of resetting operations between windows, the system continuously progresses the ranging preparation for multiple devices within the established group structure. This continuous approach reduces total time resource consumption while keeping per-operation energy usage controlled through efficient group management.

The patent applies segmentation by dividing external devices into distinct groups based on their ranging requirements. Each group is managed independently with its own scheduling, allowing the system to optimize resource allocation for each segment. This segmentation enables parallel processing of ranging preparations across different groups during the low-power state interval, reducing total time resources consumed while maintaining controlled energy usage per individual operation through focused group handling.
