Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-mode scheme of 4G or 5G NR RedCap is adopted, then the terminal can communicate with the network, but the terminal is unable to adapt to diverse requirements of various operators, leading to degraded network performance
Solution Approach 1:
The terminal dynamically selects between 4G and 5G networks based on real-time conditions and operator requirements. The network selection is not fixed but adaptable, allowing the terminal to switch between communication modes to optimize performance for different operator deployments and service requirements.
Solution Approach 2:
The terminal changes its communication parameters by selecting different network modes (4G or 5G) based on throughput requirements and power consumption constraints. This parameter adjustment enables adaptation to diverse operator requirements while maintaining reliable network performance.
2Productivity
If 5G deployment is pursued for medium-rate IOT, then higher data rates are achieved, but power consumption increases
Solution Approach 1:
The terminal adjusts its communication parameters by selecting 5G mode when high throughput is required and 4G mode when power consumption needs to be reduced. This dynamic parameter change allows the system to optimize the trade-off between data rate and power consumption based on actual service requirements.
Solution Approach 2:
The system dynamically switches between 4G and 5G communication modes based on real-time throughput requirements and power constraints, enabling flexible adaptation to different medium-rate IOT scenarios such as video monitoring versus sensor data transmission.
3Adaptability or versatility
If 4G network is used for seamless coverage, then broader compatibility is achieved, but spectrum utilization efficiency decreases
Solution Approach 1:
The terminal dynamically selects between 4G and 5G networks based on operator deployment status and service requirements. When 5G is available and appropriate for the service, the terminal uses it to improve spectrum utilization; when 4G provides sufficient coverage or is required for compatibility, the terminal uses 4G to ensure seamless coverage.
Solution Approach 2:
The terminal is designed with multi-functionality to support both 4G and 5G networks, enabling it to operate universally across different operator deployments. This universal capability allows the terminal to achieve broad compatibility while efficiently utilizing available spectrum resources through intelligent network selection.

AI summary
A communication method for a multimode terminal and a communication apparatus are provided. The method includes: obtaining network camping preferable mode; and selecting a first target cell for communication when the network camping preferable mode is a rate-based selection mode, where throughput of the first target cell satisfies a target throughput requirement; or selecting a second target cell for communication when the network camping preferable mode is a power-consumption-based selection mode, where the second target cell satisfies a preset power-consumption condition, and the preset power-consumption condition is determined according to a cell selection reception level value and a cell selection quality value; or selecting a third target cell for communication when the network camping preferable mode is a hybrid selection mode, where the third target cell satisfies the preset power-consumption condition, and/or throughput of the third target cell satisfies the target throughput requirement.
