1Area of stationary object
If beam reporting is performed for multiple TRPs using existing wireless communication systems, then coverage can be extended, but coverage loss occurs and communication efficiency deteriorates
Solution Approach 1:
The patent segments the beam reporting process into distinct phases: determining whether beam reporting is needed based on power thresholds, selecting specific TRPs for reporting, and prioritizing beams based on power levels. This segmentation allows the system to handle multiple TRPs efficiently without overwhelming the communication channel, thus maintaining reliability while extending coverage.
Solution Approach 2:
The patent introduces dynamic parameter changes by adjusting beam reporting behavior based on power thresholds and signal conditions. The system changes reporting parameters (such as which TRPs to report and in what order) based on real-time power measurements, optimizing communication efficiency across extended coverage areas.
2Measurement precision
If aperiodic and periodic uplink beam reporting frameworks are implemented for multiple TRPs, then beam reporting accuracy improves, but system complexity increases
Solution Approach 1:
The patent implements dynamic beam reporting by distinguishing between aperiodic and periodic reporting modes. The system adapts its behavior based on current communication conditions, switching between reporting types as needed. This dynamic approach improves measurement precision while managing system complexity through conditional logic rather than permanently complex structures.
Solution Approach 2:
The patent applies local quality by treating different TRPs and beam conditions differently. Instead of uniform reporting for all TRPs, the system selectively reports based on local conditions at each TRP (power levels, signal quality), prioritizing those that need reporting most. This localized approach improves accuracy without requiring complex handling of all possible scenarios.
3Productivity
If power control is optimized for uplink beam reporting, then communication efficiency improves, but energy consumption increases
Solution Approach 1:
The patent optimizes power control by dynamically changing transmission power parameters based on beam reporting requirements. The system adjusts power levels to match the actual communication needs - using higher power only when necessary for specific TRPs and beams, and reducing power for other transmissions. This parameter adaptation improves communication efficiency while controlling overall energy consumption.

AI summary
Described are embodiments for uplink beam reporting. A wireless device determines an overlap in time between: a first uplink channel resource of a permissible exposure report for a cell and a second uplink channel resource of a channel state information (CSI) report for the cell. Based on the determined overlap in time, the wireless device drops the CSI report scheduled for transmission via the second uplink channel resource, and transmits the permissible exposure report via the first uplink channel resource.
