BWP Power Headroom Reporting for Uplink Scheduling

The patent segments the power headroom reporting by introducing BWP-specific power headroom reports. Instead of a single carrier-level report, the system now generates separate power headroom information for each activated BWP within a carrier. This segmentation allows the network to obtain granular power headroom data for each BWP while maintaining manageable reporting complexity through structured reporting mechanisms.

The patent adds a new dimension to power headroom reporting by introducing the BWP level. Previously, power headroom was reported only at the carrier level (one dimension). The invention extends this to include BWP-level reporting, creating a two-dimensional reporting structure (carrier × BWP) that provides more detailed information without overwhelming complexity.

The patent implements partial reporting by requiring power headroom reports only for activated BWPs rather than all configured BWPs. This partial action approach ensures that the network receives necessary power headroom information for currently active BWPs while avoiding excessive signaling overhead that would result from reporting on all possible BWPs regardless of activation status.

The patent introduces dynamic reporting where the set of BWPs for which power headroom is reported changes based on activation status. The reporting mechanism adapts dynamically to the current network state, including only activated BWPs in the report, thereby optimizing the balance between information completeness and signaling efficiency.
