Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If MIMO mode with multiple antennas is used to improve data throughput, then spectral efficiency and data rate are improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic operation mode adaptation where the network entity continuously monitors channel conditions and hardware constraints, then selects the most appropriate operation mode (SISO, SIMO, MIMO, or CA enabled) in real-time. This dynamic switching allows the system to use MIMO mode only when channel conditions warrant the additional throughput benefit, rather than operating in MIMO mode continuously, thereby reducing overall power consumption while maintaining high data throughput when needed.
Solution Approach 2:
The patent changes operational parameters (operation mode and carrier aggregation status) based on channel conditions and hardware constraints. By adjusting these parameters dynamically, the system optimizes the balance between data throughput and power consumption, selecting higher-throughput modes like MIMO only when channel conditions support them and when hardware constraints permit.
2Productivity
If carrier aggregation is enabled to increase bandwidth and data rates, then data throughput is improved, but device complexity and power consumption increase
Solution Approach 1:
The system dynamically enables or disables carrier aggregation based on real-time channel conditions and hardware constraints. Rather than maintaining carrier aggregation permanently, the system activates it only when channel conditions justify the additional data rate benefit, thereby reducing operational complexity and power consumption during periods when multiple carriers are not needed.
Solution Approach 2:
The patent dynamically adjusts the carrier aggregation parameter (enabled/disabled) based on channel conditions and hardware constraints. This parameter change allows the system to simplify operation by disabling carrier aggregation when it provides minimal benefit, thereby reducing device complexity while maintaining high data rates when carrier aggregation is advantageous.
3Adaptability or versatility
If multiple operation modes are supported to adapt to different channel conditions, then system adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic operation mode selection mechanism that automatically adapts to changing channel conditions and hardware constraints. The network entity continuously evaluates current conditions and switches between SISO, SIMO, MIMO, and carrier aggregation modes as needed. This dynamic adaptation provides high versatility without requiring manual configuration or complex permanent multi-mode hardware, as the system activates only the necessary modes based on real-time needs.

AI summary
A system and method for operation mode adaptation is operable by a network entity that determines channel conditions between the network entity and a second network entity. The network entity determines its hardware constraints and power consumption requirements. The network entity balances data throughput with power consumption for the network entity by selecting a hardware allocation, based at least in part on the channel conditions, the hardware constraints, and the power consumption requirements. In some implementations, the network entity balances data throughput with power consumption for the network entity by selecting an operation mode, based at least in part on the channel conditions, the hardware constraints, and the power consumption requirements.
