Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication devices use existing communication structures, then device portability and functionality are improved, but communication flexibility and efficiency remain limited
Solution Approach 1:
The patent implements dynamic bandwidth part (BWP) configuration where the network can flexibly allocate and reconfigure bandwidth parts for different UEs based on traffic conditions. The BWP configuration includes dynamic adjustment of frequency domain resources, time domain resources, and numerical parameters, allowing the communication structure to adapt to varying service requirements without fixed rigid structures
Solution Approach 2:
The patent changes key communication parameters including subcarrier spacing, cyclic prefix length, and bandwidth part configurations to optimize communication efficiency. By dynamically adjusting these parameters based on service type (eMBB, URLLC, eMTC) and channel conditions, the system achieves flexible communication without requiring complex structural modifications
2Productivity
If wireless communication devices use existing communication structures, then device portability and functionality are improved, but communication efficiency is limited
Solution Approach 1:
The patent segments the wide bandwidth into multiple bandwidth parts (BWPs), each optimized for specific service types. This segmentation allows efficient resource allocation where different BWPs can be assigned to different UEs or services based on their requirements, improving communication efficiency while maintaining manageable control procedures through structured resource division
Solution Approach 2:
The patent implements preliminary configuration of bandwidth parts and resource parameters through RRC signaling before actual data transmission. This preliminary action establishes the communication framework in advance, allowing efficient data transmission without real-time negotiation, thus improving communication efficiency while keeping control procedures systematic and manageable

AI summary
A user equipment (UE) is described. Receiving circuitry is configured to receive first information, second information, third information. The receiving circuitry is also configured to monitor, based on the first information, a physical downlink control channel (PDCCH) for a downlink control information (DCI) format with cyclic redundancy check (CRC) scrambled by a cell-radio network temporary identifier (C-RNTI). The receiving circuitry is also configured to receive downlink data on a physical downlink shared channel (PDSCH). Transmitting circuitry is configured to transmit a random access preamble.
