Uplink Power Control via Subframe Set Segmentation

The patent divides uplink subframes into multiple subframe sets (first subframe set and second subframe set) with different power control parameters. Each subframe set has its own pathloss reference signal and power control adjustment state, allowing independent power control optimization for each set while maintaining manageable complexity through structured segmentation.

The patent enables dynamic switching between different power control schemes based on the subframe set. The UE determines which subframe set applies to each uplink subframe and applies the corresponding power control parameters dynamically, allowing the system to adapt to changing interference characteristics while maintaining clear implementation rules.

The patent segments the power control management into distinct subframe sets, each with predetermined power control parameters. This segmentation allows the system to adapt to dynamic interference by selecting appropriate subframe sets without requiring continuous parameter reconfiguration, thus managing complexity through structured division rather than frequent changes.

The patent configures multiple subframe sets with different power control parameters in advance through higher layer signaling. The UE stores these pre-configured sets and selects the appropriate one based on the current subframe, avoiding the need for frequent real-time parameter changes and reducing signaling overhead while maintaining adaptability.

The patent divides uplink subframes into multiple subframe sets (first subframe set and second subframe set), each with dedicated power control parameters including pathloss reference signals and power control adjustment states. This segmentation enables the UE to apply appropriate power control schemes to different subframe sets, improving uplink transmission performance under dynamic interference conditions while maintaining manageable complexity through structured organization.

The patent applies different power control parameters specifically to different subframe sets based on their respective interference characteristics. Each subframe set has its own pathloss reference signal (e.g., first pathloss reference signal for first subframe set, second pathloss reference signal for second subframe set) and power control adjustment state, allowing localized optimization without requiring complete reconfiguration of the entire power control system.
