Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the minimum required time for power measurement information reporting is calculated as the sum of first minimum required time (from last downlink reference signal timing to power measurement information transmission timing) and second minimum required time (between DCI triggering the downlink reference signal and reception of the downlink reference signal), then the reporting timing accuracy is improved, but the system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the minimum required time parameters (first minimum required time and second minimum required time) before the actual reporting process. The UE is provided with these timing parameters in advance through RRC signaling or other configuration mechanisms, allowing the UE to calculate the exact reporting timing without real-time complex computations, thus improving timing accuracy while managing system complexity.
Solution Approach 2:
The patent segments the total minimum required time into two distinct components: first minimum required time (from last downlink reference signal to power measurement information transmission) and second minimum required time (between DCI triggering and downlink reference signal reception). This segmentation allows for more precise control and optimization of each timing interval separately, improving overall reporting timing accuracy while making the system more manageable.
2Speed
If the minimum required time is calculated based on pre-configured threshold value, then the processing speed is improved, but the reporting precision may be reduced
Solution Approach 1:
The patent applies parameter changes by allowing the minimum required time to be determined based on pre-configured threshold values that can be adjusted according to different scenarios, UE capabilities, and network conditions. These threshold parameters are optimized in advance to balance processing speed and reporting precision, enabling fast processing while maintaining adequate precision for various operational contexts.
3Productivity
If multiple CSI processing units are utilized for CSI reporting, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The patent segments the CSI reporting function into multiple independent CSI processing units, each capable of handling specific CSI reporting tasks. This segmentation enables parallel processing of different CSI reports, significantly improving productivity. The modular architecture allows the system to utilize multiple processing units without proportionally increasing overall complexity, as each unit is self-contained and can be independently managed.
Solution Approach 2:
The patent implements universal CSI processing units that can handle multiple types of CSI reporting functions. Each processing unit is designed to be multi-functional, capable of processing different CSI measurement types and reporting configurations. This universality improves productivity by enabling parallel processing while controlling complexity through standardized, reusable processing modules.

AI summary
A method of transmitting, by a user equipment (UE), power measurement information related to beam reporting in a wireless communication system includes: receiving downlink control information (DCI) triggering reporting of the power measurement information; receiving a downlink reference signal for reporting of the power measurement information; and transmitting, to a base station, power measurement information determined based on the received downlink reference signal. A minimum required time for reporting of the power measurement information is (i) calculated as the sum of a first minimum required time from the last timing of the downlink reference signal to a transmission timing of the power measurement information and a second minimum required time between DCI triggering the downlink reference signal and reception of the downlink reference signal or (ii) calculated based on a pre-configured threshold value related to reporting of the power measurement information.
