Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed and continuous time domain information is used in BWP configuration, then the configuration is simple and stable, but the flexibility and system resource utilization are reduced
Solution Approach 1:
The patent transforms the static, fixed time domain configuration into a dynamic, flexible configuration by introducing time domain indication information. This allows the BWP configuration to adapt to different time resources and scenarios, enabling the system to switch between different time domains based on actual needs, thereby improving flexibility without requiring complete redesign of the configuration structure
Solution Approach 2:
The patent segments the time domain configuration into separate indication information elements that can be independently configured and indicated. By dividing the time domain resources into distinct indications (such as starting symbols, ending symbols, or resource sets), the system can selectively configure specific time resources while maintaining overall configuration simplicity, thus achieving flexibility without excessive complexity
2Adaptability or versatility
If fixed and continuous time domain information is used in BWP configuration, then the configuration structure is simple, but the uplink coverage for low-cost terminals is limited
Solution Approach 1:
The patent changes the configuration parameters by introducing time domain indication information that can be adjusted according to terminal capabilities and network conditions. This allows the system to configure different time domain resources suitable for low-cost terminals with limited processing power, enabling better uplink coverage while maintaining compatibility through standardized indication mechanisms
Solution Approach 2:
The patent enables terminals to autonomously configure and select appropriate time domain resources based on their capabilities and the received BWP configuration information. Low-cost terminals can independently determine suitable time resources without requiring complex network coordination, thereby improving uplink coverage while maintaining ease of implementation through self-based decision making
Data Source
AI summary
A data transmission method. The method is performed by a base station and includes: sending bandwidth part (BWP) configuration information to a terminal, wherein the BWP configuration information includes time domain indication information for indicating time domain resources enabled by the BWP configuration information; and performing a data transmission with the terminal on the time domain resources indicated by the time domain indication information.
