Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible and configurable communication protocols are implemented to support diverse wireless devices and base stations, then adaptability and versatility improve, but device and system complexity increase
Solution Approach 1:
The patent implements dynamic protocol configuration where bandwidth parts, carrier aggregation, and beam management parameters can be adjusted in real-time based on network conditions and device capabilities. This allows the system to adapt to diverse wireless devices without requiring fixed complex protocols for all scenarios.
Solution Approach 2:
The patent changes operational parameters such as bandwidth part configurations, carrier aggregation settings, and beam management parameters to optimize communication for different device types and network conditions. By varying these parameters dynamically, the system achieves versatility without permanently increasing structural complexity.
2Productivity
If dynamic configuration of bandwidth parts and carrier aggregation is implemented, then data transmission rates improve, but processing complexity and time increase
Solution Approach 1:
The patent pre-configures bandwidth parts and carrier aggregation parameters based on device capabilities and network conditions before actual data transmission begins. This preliminary configuration reduces real-time processing complexity while maintaining high data transmission rates during active communication.
Solution Approach 2:
The patent divides the communication protocol into separate configurable modules (bandwidth part configuration, carrier aggregation settings, beam management parameters) that can be independently optimized. This segmentation allows complex processing to be distributed and managed more efficiently, reducing overall processing complexity while maintaining high transmission rates.
3Reliability
If adaptive beam management is implemented, then communication reliability improves, but computational requirements and processing time increase
Solution Approach 1:
The patent implements periodic beam management updates where beam parameters are adjusted at predetermined intervals or triggered by specific events rather than continuously. This periodic approach maintains communication reliability through regular beam optimization while reducing computational burden and processing time compared to continuous adaptive beam management.

AI summary
A wireless device may receive a first downlink control information (DCI). The first DCI may comprise a frequency domain resource allocation (FDRA) field and a transmission configuration indicator (TCI) state indication field. The wireless device may determine that a TCI state indicated by the TCI state indication field is used for receptions of a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) based on: the FDRA field being set to a predefined value and the first DCI being received with a configured scheduling radio network temporary identifier (CS-RNTI). Using the TCI state, the wireless device may receive a second DCI via the PDCCH and a transport block (TB) via the PDSCH.
