1Productivity
If power headroom reporting is implemented for full-duplex communications, then network performance and channel usage efficiency are improved, but device complexity and configuration requirements increase
Solution Approach 1:
The power headroom report is segmented into different types: first power headroom report for full-duplex communications and second power headroom report for half-duplex communications. This segmentation allows the system to handle different communication modes separately, improving channel usage efficiency while maintaining manageable complexity through structured reporting categories.
Solution Approach 2:
The system dynamically switches between different power headroom reporting modes based on the communication type. The apparatus determines whether to send full-duplex or half-duplex power headroom reports based on the actual communication mode, enabling adaptive reporting that optimizes performance without requiring permanent complex configurations.
2Measurement precision
If differentiated power headroom reporting is implemented for full-duplex and half-duplex communications, then measurement precision and network optimization are improved, but loss of information and processing overhead increase
Solution Approach 1:
The power headroom information is segmented into distinct reports based on communication mode. The first power headroom report contains full-duplex specific parameters while the second contains half-duplex parameters. This segmentation improves measurement precision by ensuring the right data is collected for each mode while minimizing processing overhead through targeted data collection rather than comprehensive reporting for all modes.
Solution Approach 2:
Each power headroom report is tailored to the specific communication mode with appropriate local parameters. The full-duplex report includes parameters relevant to simultaneous transmission while the half-duplex report includes parameters for sequential transmission. This local quality approach ensures accurate measurement for each mode without requiring processing of irrelevant information, reducing overall processing overhead.
