Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional 2/3/4G mobile communication technologies are used for MTC, then existing infrastructure can be utilized, but system complexity increases and power consumption increases
Solution Approach 1:
The patent segments the MTC system into distinct components: machine communication terminals, base stations, and a simplified scheduling mechanism. By dividing the system architecture and assigning specific functions to each component, the complexity is managed through modular design while maintaining compatibility with existing 2/3/4G infrastructure.
Solution Approach 2:
The base station is designed to perform multiple functions: serving traditional human communication while simultaneously supporting MTC terminals with simplified scheduling. This multi-functionality allows the system to leverage existing infrastructure while introducing MTC capabilities without requiring separate dedicated infrastructure.
2Adaptability or versatility
If conventional 2/3/4G mobile communication technologies are used for MTC, then existing infrastructure can be utilized, but power consumption increases
Solution Approach 1:
The patent implements periodic scheduling where machine communication terminals transmit data at predetermined time intervals rather than continuously. This periodic transmission mode significantly reduces power consumption by allowing terminals to enter low-power states between transmissions, while the base station maintains readiness to receive data at scheduled intervals.
Solution Approach 2:
The scheduling mechanism operates autonomously based on business registration information without requiring complex terminal-side processing. Terminals simply follow predetermined scheduling instructions, reducing the computational burden and power consumption at the terminal level while the base station handles the scheduling logic.
3Quantity of substance
If machine communication devices are grouped for resource sharing, then resource utilization improves, but flow complexity increases and deployment flexibility reduces
Solution Approach 1:
The patent applies different scheduling strategies based on terminal characteristics and business registration information. Each terminal receives customized time-frequency resource allocation tailored to its specific needs, allowing efficient resource sharing while maintaining simple, localized scheduling logic at each base station without complex centralized coordination.
4Quantity of substance
If machine communication devices are grouped for resource sharing, then resource utilization improves, but battery life reduction rate increases
Solution Approach 1:
By implementing periodic scheduling with predetermined time intervals, terminals can remain in low-power states between transmissions. This significantly extends battery life compared to continuous or frequent transmission modes, while still enabling effective resource sharing among multiple devices through coordinated periodic access.

AI summary
An MTC method includes: a base station receives a terminal identity and business registration information from a terminal, the business registration information including a business type and service subscription information; the base station allocates time-frequency reporting resource information to the terminal according to the business registration information; the base station sends the time-frequency reporting resource information to the terminal; and the base station receives an uplink data packet from the terminal according to the time-frequency reporting resource information. In the embodiment, the base station allocates the time-frequency reporting resource information to the terminal to ensure that the terminal sends the uplink data packet to the base station. Such a scheduling process is simple and consistent, which can reduce complexity and power consumption of MTC, and can further reduce deployment cost of an MTC system and prolong the service life of battery-powered equipment.
