Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple physical control channels are transmitted simultaneously in uplink, then the data traffic capacity and service speed are improved, but the resource management complexity and interference management difficulty increase
Solution Approach 1:
The patent segments multiple physical control channels into different resource groups and assigns them to different time-frequency resources. This segmentation allows simultaneous transmission of multiple channels while managing resource allocation systematically, thereby improving data traffic capacity without overwhelming resource management complexity.
Solution Approach 2:
The patent implements dynamic resource allocation and adaptive transmission schemes where the system can flexibly adjust resource assignment based on channel conditions and traffic demands. This dynamic approach enables efficient handling of multiple simultaneous control channels, improving productivity while keeping resource management tractable through adaptive rather than static configurations.
2Speed
If multiple physical control channels are transmitted simultaneously in uplink, then the transmission rate per user is improved, but the latency and resource conflicts increase
Solution Approach 1:
The patent utilizes multiple dimensions of resource allocation including time, frequency, and spatial domains to transmit multiple control channels simultaneously. By expanding into these additional dimensions, the system achieves higher transmission rates without causing time conflicts that would increase latency, as channels are separated across different resource dimensions rather than competing for the same time slot.
3Quantity of substance
If multiple physical control channels are transmitted simultaneously in uplink, then the number of connected devices is improved, but the interference management and resource allocation difficulty increase
Solution Approach 1:
The patent introduces intermediary mechanisms such as resource coordination protocols and interference management algorithms that mediate between multiple simultaneous control channel transmissions. These intermediaries systematically manage resource allocation and detect/mitigate interference, enabling support for a larger number of connected devices while controlling interference levels through coordinated resource usage.
