One Shot HARQ Feedback Timer Control for Power Savings

The patent segments the HARQ feedback process by introducing a one-shot feedback mechanism that consolidates multiple HARQ process acknowledgments into a single feedback transmission. This segmentation allows the UE to manage RTT timers more efficiently by starting or restarting them selectively based on specific conditions, rather than managing multiple separate timer instances, thereby reducing overall timer management complexity while optimizing power savings.

The patent implements dynamic timer management where the RTT timer is started or restarted based on dynamic conditions such as the reception of downlink data or the status of other timers. This dynamic approach allows the system to adapt timer behavior to current operational states, optimizing power consumption by activating timers only when necessary rather than maintaining static timer configurations.

The patent applies universality by designing the one-shot HARQ feedback mechanism to serve multiple HARQ processes simultaneously through a single feedback transmission. This multi-functional approach improves scheduling efficiency by reducing the number of separate feedback transmissions required, while the selective RTT timer management maintains sufficient timing control precision for each individual process.

The patent introduces an intermediary mechanism where the one-shot feedback acts as a mediator that consolidates timing information for multiple HARQ processes. By using this intermediary approach, the system achieves improved scheduling efficiency through batched feedback while maintaining adequate timing precision through conditional RTT timer management for each process.
