Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If carrier aggregation technology and multiple input multiple output (MIMO) technology are used to increase data throughput, then communication capacity is improved, but network energy consumption increases
Solution Approach 1:
The patent applies dynamic slot configuration where the base station can flexibly adjust the number of downlink slots and uplink slots based on real-time traffic conditions. When traffic is heavy, more downlink slots are allocated to maintain high throughput. When traffic is light, the number of slots is reduced to minimize network energy consumption, thus resolving the contradiction between productivity and energy usage.
Solution Approach 2:
The patent changes the temporal parameters of slot configurations dynamically. By adjusting the duration and distribution of downlink and uplink slots within a frame, the system can optimize between data transmission capacity and energy consumption. This parameter adjustment allows the network to adapt to varying traffic loads and achieve energy-efficient operation without sacrificing throughput when needed.
2Adaptability or versatility
If the number of services and user equipments is increased to meet communication demands, then communication capacity is improved, but power saving requirements become more challenging
Solution Approach 1:
The patent enables dynamic adaptation of slot configurations to match actual service demands. When few services are active, the base station uses fewer slots, reducing overall network power consumption. When many services require high capacity, the system dynamically increases slot allocation. This dynamic approach allows the network to serve diverse services while maintaining power efficiency.
3Use of energy by stationary object
If slot configurations are made flexible to optimize energy consumption, then network energy saving is improved, but system complexity increases
Solution Approach 1:
The patent segments the communication frame into multiple slots that can be independently configured. Each slot can be designated as downlink or uplink based on traffic conditions. This segmentation allows granular control over resource allocation, enabling energy optimization without requiring complete redesign of the communication protocol. The segmented structure simplifies the complexity by providing modular building blocks for configuration.
Solution Approach 2:
The slot configuration mechanism serves multiple functions: it controls downlink throughput, manages uplink opportunities, and optimizes energy consumption simultaneously. By making the slot configuration multi-functional, the patent avoids adding separate control mechanisms for each objective, thus reducing overall system complexity while achieving energy savings.
