Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dynamic bandwidth part configurations are implemented to improve bandwidth utilization, then network performance and adaptability are improved, but device complexity and protocol management overhead increase
Solution Approach 1:
The patent implements dynamic bandwidth part (BWP) configurations that allow base stations to adaptively adjust bandwidth allocation based on real-time traffic conditions and device capabilities. The system dynamically switches between different BWP configurations (e.g., first BWP for high bandwidth needs, second BWP for low bandwidth needs) to optimize resource utilization while managing complexity through predefined configuration sets.
Solution Approach 2:
The system changes key parameters such as bandwidth width, time duration, and resource allocation ratios based on traffic load conditions. By adjusting these parameters dynamically, the network can optimize productivity during high-load periods while reducing complexity during low-load periods, resolving the contradiction between performance and system complexity.
2Adaptability or versatility
If adaptive resource management protocols are applied to improve resource allocation efficiency, then network adaptability to varying traffic conditions improves, but the complexity of system configuration and management increases
Solution Approach 1:
The patent employs preliminary configuration of multiple bandwidth parts and resource management protocols before actual data transmission occurs. The base station pre-configures different BWP settings and selection criteria, so when traffic conditions change, the system can quickly switch between predefined configurations without complex real-time calculations, thus achieving high adaptability while managing configuration complexity.
Solution Approach 2:
The system segments the bandwidth into multiple discrete parts (first BWP, second BWP, etc.), each with specific characteristics suitable for different traffic conditions. This segmentation allows the network to independently manage and switch between configurations, improving adaptability to varying traffic patterns while reducing the complexity of managing a single monolithic resource allocation system.
3Productivity
If bandwidth parts are dynamically switched based on traffic load, then resource allocation efficiency improves, but time for configuration switching and potential data loss increases
Solution Approach 1:
The system performs preliminary configuration of multiple bandwidth parts with predetermined parameters before actual switching is needed. When traffic conditions require a bandwidth change, the base station can quickly switch between pre-configured BWPs without performing complex real-time calculations, thereby improving resource allocation efficiency while minimizing switching time and potential data loss.
Data Source
AI summary
A wireless device receives, from a first base station, a RRC release message comprising a suspend configuration, wherein the suspend configuration comprises a configuration of a small data transmission (SDT) procedure indicating a radio bearer configured for the SDT procedure. The device suspends, based on the suspend configuration, one or more radio bearers comprising the radio bearer configured for the SDT procedure. Based on initiating the SDT procedure, the wireless device resumes the radio bearer configured for the SDT procedure; and transmits, to a second base station, a radio resource control (RRC) resume request message. The wireless device communicates with the second base station and during the SDT procedure, data associated with the SDT procedure, and transmits to the second base station and during the SDT procedure, a user equipment (UE) assistance information message comprising a non-SDT indication, wherein the non-SDT indication indicates availability of data mapped to a radio bearer which is not configured for the SDT procedure, and a resume cause associated with the data. The wireless device receives, from the second base station and after transmitting the UE assistance information message, an RRC response message.
