Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple access systems support diverse communication services (audio, data, etc.), then service coverage and versatility are improved, but system complexity and resource allocation difficulty increase
Solution Approach 1:
The patent implements a universal resource allocation framework that handles multiple communication services (audio, data, etc.) through unified procedures. The base station and user equipment use standardized signaling messages and resource allocation mechanisms that work across different service types, allowing the system to support diverse services without requiring separate specialized protocols for each service type.
Solution Approach 2:
The patent segments the resource allocation process into distinct phases and components: service type identification, resource requirement determination, allocation decision making, and signaling transmission. This segmentation allows the complex multi-service system to be managed through modular, manageable steps, reducing overall system complexity while maintaining versatility.
2Productivity
If wireless communication systems share available system resources (bandwidth, transmit power) among multiple users, then system productivity and user capacity are improved, but resource allocation efficiency and signal transmission reliability may deteriorate
Solution Approach 1:
The patent applies local quality by allocating resources based on individual user equipment characteristics, service requirements, and channel conditions. Each user receives customized resource allocation parameters (bandwidth, power, time slots) tailored to their specific needs, ensuring that resource sharing does not compromise the reliability requirements of individual users while maintaining high overall system capacity.
Solution Approach 2:
The patent implements dynamic resource allocation where the base station continuously adjusts bandwidth, power, and time resource distribution based on real-time channel conditions, user activity, and service priorities. This dynamic adaptation allows the system to maintain optimal signal transmission reliability for each user while maximizing overall user capacity through efficient resource sharing.
3Productivity
If advanced signal processing techniques and multiplexing are employed, then communication capacity and resource utilization are improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent introduces standardized signaling messages as intermediaries between the base station and user equipment for resource allocation and status reporting. These signaling messages encapsulate complex resource allocation decisions and channel state information, allowing advanced signal processing and multiplexing techniques to be implemented while maintaining relatively simple device structures through standardized interfaces that hide processing complexity.

AI summary
A user equipment (UE) operation related to at least one of embodiments of the disclosure may include multiplexing a plurality of UCIs on a single physical uplink shared channel (PUSCH), and transmitting the single PUSCH in which the plurality of UCIs are multiplexed. Based on that the UE is configured to multiplex UCIs having different priorities on the same PUSCH, that a priority of a first UCI included in the plurality of UCIs is Priority-H higher than Priority-L, and that the first UCI with the Priority-H includes 2-part channel state information (CSI), the UE may drop all hybrid automatic repeat request-acknowledgement (HARQ-ACK) information of a second UCI with the Priority-L lower than the Priority-H, and map a first part of the CSI and a second part of the CSI onto the single PUSCH.
