Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple TRPs are activated simultaneously to improve coverage and reliability, then network reliability is improved, but energy consumption increases
Solution Approach 1:
The system dynamically switches between different TRP configurations based on real-time network conditions and traffic demands. The network can transition from single-TRP to multi-TRP activation, adjusting the number of active TRPs dynamically to balance reliability requirements with energy consumption constraints.
Solution Approach 2:
The patent changes the operational parameters of TRPs by adjusting transmission power levels, activation states, and resource allocation configurations. By modifying these parameters, the system can achieve reliable communication with reduced energy consumption compared to continuously activating all TRPs at full power.
2Productivity
If bandwidth is increased to improve data transmission capacity, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent segments the total bandwidth into multiple bandwidth parts (BWPs), each allocated to different TRPs or service types. This segmentation allows independent management of bandwidth resources, simplifying the overall complexity while maintaining high total capacity through parallel transmission channels.
Solution Approach 2:
The system introduces an additional dimension of resource management by allocating different bandwidth parts to different frequency ranges and time slots. This multi-dimensional allocation strategy increases data transmission capacity while distributing the management complexity across multiple independent dimensions rather than requiring complex single-dimension control.
3Productivity
If carrier aggregation is implemented to improve bandwidth utilization, then productivity is improved, but ease of operation deteriorates
Solution Approach 1:
The patent creates a universal resource allocation framework that manages multiple carriers and bandwidth parts through a unified control mechanism. This universal approach allows the same resource allocation algorithms and control procedures to be applied across different carrier configurations, simplifying operation despite the complexity of managing multiple aggregated carriers.

AI summary
A wireless device can receive one or more configuration parameters indicating a first transmission and reception point (TRP), from TRPs, is used during an energy saving (ES) operation of one or more of the TRPs. During the ES operation, the wireless device can receive first downlink signals of the first TRP and not receive second downlink signals of the second TRP.
