Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power control is managed independently for each wireless communication link, then the complexity of power control management increases, but the communication reliability and quality improve
Solution Approach 1:
The patent divides power control management into separate independent processes for each wireless communication link. Each link has its own power control parameters (P0, alpha, pathloss reference) that are configured and managed independently, allowing the system to handle multiple links with different power control requirements without mutual interference, thus improving communication reliability while maintaining manageable complexity through modular organization.
Solution Approach 2:
The patent implements dynamic power control where each link can independently adjust its transmit power based on real-time channel conditions, power control parameters, and link-specific feedback. This dynamic adaptation allows each link to optimize its power usage independently, improving overall communication reliability without requiring centralized complex management of all links simultaneously.
2Adaptability or versatility
If power control information is obtained and processed for multiple independent links, then the adaptability of power management improves, but the processing complexity increases
Solution Approach 1:
The patent segments power control information processing into distinct independent procedures for each link. Each link receives, processes, and applies its own power control parameters (P0_n, alpha_n, pathlossReference_n) separately, enabling the system to adapt to different channel conditions and requirements for each link while avoiding the complexity of joint optimization across multiple links.
Solution Approach 2:
The patent applies local quality by allowing each wireless link to have its own customized power control parameters and processing characteristics tailored to its specific channel conditions, frequency band, and service requirements. This localized processing enables high adaptability for each link while keeping the overall system complexity manageable through independent local decision-making.

AI summary
Various aspects of the disclosure relate to power control for independent links. For example, power control at a device may be based on transmissions on multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, power control for the first device may be based on power control commands received on multiple links. In some scenarios, a power control constraint may be met taking into account the transmission power on multiple links.
