Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of receiving antennas is increased to improve channel capacity and transmission performance, then the system can support higher data rates and better spatial multiplexing, but different user equipment will have different interference measurement criteria making it difficult for the network to objectively reflect actual interference
Solution Approach 1:
The patent changes the parameter of receiving mode by configuring specific receiving beamforming weights or precoding matrix indicators for interference measurement. This ensures that even with multiple receiving antennas, all UEs measure interference under the same effective receiving condition, thereby maintaining measurement accuracy and consistency across different UE configurations.
2Ease of operation
If the network allows UEs to use their own receiving modes for interference measurement, then the measurement process is simple and flexible, but the interference measurement results cannot be accurately compared across different UEs and do not reflect the actual interference experienced during data transmission
Solution Approach 1:
The patent applies preliminary action by configuring the receiving mode parameters (such as precoding matrix indicators or beamforming weights) before the interference measurement takes place. The network provides these configurations through RRC signaling or downlink control information, ensuring that all UEs are pre-aligned to use consistent receiving modes for interference measurement, thus guaranteeing measurement consistency before actual measurement occurs.
3Measurement precision
If the network configures specific receiving modes for interference measurement, then measurement consistency across UEs is improved, but the configuration complexity and signaling overhead increase
Solution Approach 1:
The patent uses existing downlink control signaling mechanisms (such as PDCCH, PDSCH with DCI formats, or RRC configuration messages) to convey the receiving mode configurations for interference measurement. By reusing established signaling protocols that UEs are already equipped to handle, the patent avoids introducing entirely new complex configuration procedures, thus minimizing additional system complexity while achieving measurement consistency.
