Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If zero-power IoT devices are integrated into 5G NR systems, then system versatility is improved, but compatibility issues and resource allocation conflicts arise
Solution Approach 1:
The patent segments the time-frequency resources into dedicated zero-power IoT resource pools separated from conventional 5G NR resources. This segmentation allows zero-power IoT devices to operate without interfering with regular 5G communications and vice versa, resolving compatibility issues while maintaining system versatility.
Solution Approach 2:
The patent introduces a dedicated control information mechanism that acts as an intermediary between zero-power IoT devices and the 5G NR system. This control information facilitates coordinated resource allocation and communication between the two different system types, improving compatibility.
2Productivity
If resource pools are allocated for zero-power IoT communication, then communication efficiency is improved, but interference with other wireless devices increases
Solution Approach 1:
The patent applies local quality by creating dedicated resource pools with specific time-frequency characteristics tailored for zero-power IoT devices. These localized resource allocations ensure that zero-power IoT communications occur in protected time slots and frequency ranges, minimizing interference with other wireless devices while maximizing communication efficiency for the target application.
3Reliability
If channel monitoring is performed continuously, then collision detection is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by establishing fixed time slots and resource pools for zero-power IoT communications. Instead of continuous monitoring, devices only need to monitor during these predetermined periods, significantly reducing power consumption while maintaining reliable collision detection through the structured time-division approach.
4Reliability
If time-frequency resources are reserved for zero-power IoT, then communication reliability is improved, but resource utilization for other services decreases
Solution Approach 1:
The patent segments the overall time-frequency resource space into distinct portions: dedicated zero-power IoT resource pools and conventional 5G NR resources. This segmentation ensures that zero-power IoT devices receive guaranteed resource allocation for reliable communication, while other services continue to utilize the remaining resources efficiently, balancing both reliability and overall productivity.

AI summary
A zero-power IoT reader, e.g., a UE, may be configured to broadcast, for other wireless devices, a first control information including a first scheduling information of a first resource pool including first time-frequency resources for zero-power IoT communication, and perform the zero-power IoT communication in the first resource pool associated with the first control information from one or more passive network entities. The zero-power IoT reader may also receive a second control information including a second scheduling information of a second resource pool including second time-frequency resources from a second UE among the other wireless devices, and determine the first resource pool including the first time-frequency resources for zero-power IoT communication based on the second control information.
