Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If flexible measurement and signaling mechanisms are used to support wideband frequency resources and spatial domain resources, then wireless communication efficiency is improved, but signaling overhead increases
Solution Approach 1:
The patent applies universality by creating a unified resource configuration framework where a single configuration message can indicate resource reuse modes applicable to multiple reference signals and resource groups. The network node configures resource reuse modes that can be universally applied across different frequency regions, polarization modes, and spatial resources, reducing the need for separate signaling for each resource type.
Solution Approach 2:
The patent employs parameter changes by introducing configurable resource reuse mode parameters that can be dynamically adjusted. The network node configures specific parameters such as frequency region indicators, polarization mode indicators, and spatial resource indicators that change the resource allocation behavior. These parameter changes allow the system to adapt resource usage patterns without requiring complete reconfiguration messages.
2Measurement precision
If resource reuse modes are configured per reference signal or resource group to reduce interference, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing reference signals into distinct resource groups, where each group can be configured with specific resource reuse modes. Instead of configuring each reference signal individually, the system segments them into logical groups based on their resource characteristics (frequency region, polarization, spatial resources). This segmentation reduces the complexity of configuration while maintaining precise measurement capabilities for each group.
Solution Approach 2:
The patent implements local quality by allowing different resource reuse modes to be applied to different resource groups based on their specific characteristics. Each resource group can have tailored configurations for frequency regions, polarization modes, and spatial resources, optimizing measurement precision for local conditions without requiring complex global configuration management.
3Adaptability or versatility
If measurements across large scale of frequency resources are performed to support adaptation among different bandwidth parts, then adaptability is improved, but the impact of radio frequency tuning increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring resource reuse modes and resource groups before measurements are performed. The network node provides advance configuration information including resource group identifiers, frequency region indicators, and polarization mode indicators. This preliminary configuration allows the user equipment to prepare measurement settings in advance, reducing the time required for radio frequency tuning when adapting to different bandwidth parts.
Solution Approach 2:
The patent implements dynamics by enabling dynamic switching between different resource reuse modes and resource groups based on current communication conditions. The configured resource reuse modes allow the system to dynamically adapt measurements across large scale frequency resources while managing radio frequency tuning time through pre-established configuration options that can be quickly activated.
