Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power amplifier transmits signals at the same power in all operating modes, then the device structure remains simple, but the radiation performance is degraded and throughput decreases
Solution Approach 1:
The patent implements dynamic power adjustment by determining different target powers for different antenna operating modes and dynamically adjusting the power amplifier output based on the current operating mode. This resolves the contradiction by making the power transmission adaptive rather than static, improving radiation performance without requiring complex structural changes.
Solution Approach 2:
The patent changes the power parameter dynamically based on operating mode by determining a target power for each mode and adjusting the power amplifier accordingly. This parameter adjustment strategy improves radiation performance while keeping the control mechanism relatively simple through predefined mode-based power settings.
2Reliability
If the antenna transmits at constant power, then the power amplifier operation is simplified, but the signal quality deteriorates in certain scenarios
Solution Approach 1:
The patent adjusts the power parameter based on operating mode by determining a target power for each mode and controlling the power amplifier to output signals at the appropriate power level. This improves signal quality in different scenarios while maintaining relatively simple control through mode-based power determination.
3Productivity
If the antenna operates in multiple modes with different powers, then the radiation performance improves, but the control system becomes more complex
Solution Approach 1:
The patent implements dynamic power adjustment for different antenna operating modes, where the power amplifier dynamically changes its output power based on the current operating mode. This dynamic control improves throughput rate by optimizing power for each mode while keeping the control system manageable through mode-based classification.
Solution Approach 2:
The patent changes the power parameter according to operating mode by determining target powers for different modes and adjusting the power amplifier accordingly. This parameter adaptation improves productivity through optimized power transmission in each mode while maintaining control system simplicity through predefined mode-specific power settings.

AI summary
The control method includes determining a target operating mode in response to a target instruction in a target scenario, controlling a target antenna in the target operating mode to receive a first radiated signal at a first frequency, and transmitting a second radiated signal at a second frequency. The first frequency and the second frequency belong to a same frequency band. The target operating mode includes a plurality of different antenna operating modes. Under at least two of the antenna operating modes of the plurality of different antenna operating modes, the second radiated signal at the second frequency is transmitted at different target powers to cause transmission powers of the plurality of different operating modes to be equal to or approach a power limit of the target scenario. The target power represents a power of a radio frequency path between an antenna port of the target antenna and a transceiver.
