Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If carrier aggregation and dynamic resource allocation are implemented, then data rates and network performance are improved, but device complexity and resource management difficulty increase
Solution Approach 1:
The patent segments the bandwidth into multiple bandwidth parts (BWP), each with distinct characteristics and purposes. This segmentation allows the system to manage complex carrier aggregation scenarios by dividing the overall resource management into smaller, more manageable units, where each BWP can be independently configured and controlled based on specific service requirements
Solution Approach 2:
The patent implements dynamic resource allocation through configurable bandwidth parts that can be flexibly adjusted based on traffic conditions and service requirements. The dynamic nature allows the system to adapt resource allocation in real-time, optimizing data rates while managing complexity through automated configuration mechanisms
2Adaptability or versatility
If bandwidth parts are configured for different services, then resource utilization is optimized, but system complexity and configuration difficulty increase
Solution Approach 1:
The bandwidth part configuration mechanism serves multiple functions simultaneously: it supports different service types (e.g., eMBB, URLLC, mMTC), enables flexible resource allocation, and provides a standardized configuration interface. This multi-functionality allows the same BWP framework to handle diverse service requirements without proportionally increasing system complexity
Solution Approach 2:
The patent utilizes parameter changes within the BWP configuration to adapt to different service requirements. By modifying parameters such as bandwidth size, subcarrier spacing, and cyclic prefix length within the BWP framework, the system can optimize resource allocation for various services while maintaining a consistent structural approach that limits complexity growth

AI summary
A wireless device may receive configuration parameters indicating a ratio threshold for selecting between rate matching and puncturing. The wireless device may receive a first downlink control information (DCI) scheduling an uplink transport block (TB) via uplink resources of the cell, and a second DCI indicating a transmission cancelation on one or more resources of the uplink resources. The wireless device may map the uplink TB to a portion of the uplink resources based on the rate matching in response to a ratio of the one or more resources to the uplink resources being equal to or greater than the ratio threshold, and the puncturing in response to the ratio being less than the ratio threshold. The wireless device may transmit the uplink TB via the portion of the uplink resources in response to the mapping.
