1Object-generated harmful factors
If transmit power control is implemented at maximum bandwidths (320 MHz/160+160 MHz), then interference reduction and power saving are improved, but the complexity of power management increases
Solution Approach 1:
The patent applies preliminary action by pre-defining transmit power values for different bandwidths (20 MHz, 40 MHz, 80 MHz, 160 MHz, and 320 MHz) in a transmit power envelope element. This allows devices to have power control parameters ready in advance for maximum bandwidths, enabling quick power adjustment without complex real-time calculations, thus reducing interference while managing complexity through pre-computation.
2Productivity
If multi-band aggregation is implemented across 2.4 GHz, 5.8 GHz, and 6-7 GHz bands, then throughput and rate are improved, but the complexity of managing simultaneous communication increases
Solution Approach 1:
The patent applies universality by creating a unified transmit power envelope mechanism that works across multiple frequency bands (2.4 GHz, 5.8 GHz, and 6-7 GHz) and multiple bandwidth configurations. The same power envelope element structure and management approach is used universally for all bands, simplifying multi-band aggregation management while maintaining high throughput capabilities.
3Productivity
If transmit power is increased to support maximum bandwidths (320 MHz/160+160 MHz), then spectrum utilization is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by implementing adjustable transmit power values that can be dynamically set for different bandwidths through the transmit power envelope element. Devices can adaptively increase power for 320 MHz operations when high spectrum utilization is needed, or reduce power for lower bandwidths, optimizing the balance between spectrum utilization and power consumption based on actual communication requirements.
