Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If channel measurement resources are configured for multiple transmission-reception-points, then channel state information reporting accuracy is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent divides channel measurement resources into separate sets, where each set is associated with a specific transmission-reception-point. This segmentation allows the wireless device to independently measure and report channel state information for each TRP, improving measurement accuracy while maintaining manageable complexity through structured resource organization.
Solution Approach 2:
The patent introduces an additional dimension of resource configuration by associating measurement resources not only with time-frequency slots but also with specific transmission-reception-points. This multi-dimensional resource mapping enables the system to distinguish and measure channels from different TRPs, enhancing reporting accuracy without overwhelming device complexity.
2Measurement precision
If channel measurement resources are configured for multiple transmission-reception-points, then channel state information reporting accuracy is improved, but power consumption increases
Solution Approach 1:
By segmenting measurement resources into distinct sets for different TRPs, the patent enables the wireless device to perform measurements only on configured resources rather than continuously monitoring all possible transmissions. This targeted measurement approach improves channel state information accuracy while reducing overall power consumption.
Solution Approach 2:
The patent implements periodic channel measurement on configured resources rather than continuous measurement. The wireless device measures channel state information at scheduled intervals on pre-configured measurement resources, which maintains accurate reporting while significantly reducing power consumption compared to continuous monitoring.
3Productivity
If separate sets of channel measurement resources are indicated for different transmission-reception-points, then multi-TRP operation efficiency is improved, but signaling overhead increases
Solution Approach 1:
The patent creates a universal resource configuration framework where a single set of channel measurement resources can serve multiple transmission-reception-points through explicit association. This multi-functional resource allocation improves multi-TRP operation efficiency by enabling coordinated measurements while minimizing redundant signaling compared to configuring entirely separate resource sets for each TRP.
