Engineering Contradiction Analysis
1Productivity
If power control for PUSCH is implemented in full-duplex mode, then spectral efficiency is improved, but inter-cell interference increases
Solution Approach 1:
The patent applies local quality by configuring different SRS resource set rules with specific power control parameters for different duplex modes. The network node provides mode-specific configurations that tailor power control behavior to either half-duplex or full-duplex operation, allowing localized optimization of power levels to reduce inter-cell interference while maintaining spectral efficiency in full-duplex scenarios.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting power control parameters (such as power offsets, path loss compensation factors) based on the duplex mode. The network node configures different parameter sets for SRS resource sets associated with half-duplex versus full-duplex modes, enabling the system to adapt power levels to changing operational conditions and mitigate interference.
2Use of energy by moving object
If power control configuration is optimized for full-duplex mode, then power control efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing SRS resource sets into distinct groups with different power control configurations for half-duplex and full-duplex modes. This segmentation allows the UE to apply pre-configured rules specific to each duplex mode, improving power control efficiency without requiring complex real-time calculations, as the configurations are prepared in advance by the network node.
Solution Approach 2:
The patent implements preliminary action by having the network node provide and configure SRS resource set rules in advance for both half-duplex and full-duplex modes. The UE receives and stores these configurations beforehand, so when switching between duplex modes, the device can immediately apply the appropriate pre-configured power control rules without complex real-time decision-making, thus improving efficiency while managing complexity.
