Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all configuration information for uplink signals is stored in user equipment, then measurement precision and communication reliability are improved, but device complexity and memory overhead increase
Solution Approach 1:
The patent extracts only the necessary configuration information (target configuration information) from the complete set of uplink signal configuration information. The network device indicates which specific configuration information items should be stored, allowing the UE to discard unnecessary data while maintaining pathloss measurement capability. This directly reduces memory overhead while preserving measurement precision.
Solution Approach 2:
The configuration information is segmented into target configuration information (to be stored) and non-target configuration information (to be discarded). The network device provides indication information that divides the complete configuration set into these two segments, enabling selective storage that balances measurement requirements with memory constraints.
2Reliability
If significant memory resources are allocated for pathloss measurement, then communication reliability is improved, but manufacturing cost increases
Solution Approach 1:
By extracting only the essential configuration information items indicated by the network device, the patent reduces the total memory capacity required in the UE. This lowers manufacturing costs while maintaining sufficient data for reliable pathloss measurement and wireless communication.
3Adaptability or versatility
If all configuration information is retained, then adaptability to different communication scenarios is improved, but data storage capacity increases
Solution Approach 1:
The patent implements a dynamic configuration information storage strategy where the UE stores only the configuration items currently indicated by the network device for pathloss measurement. This dynamic selection maintains adaptability to different communication scenarios while minimizing storage capacity requirements at any given time.

AI summary
A data storage method includes acquiring configuration information for an uplink signal sent by a network device; and in response to a number of target configuration information to be stored being less than a number of configuration information for the uplink signal sent by the network device, storing the target configuration information, and discarding configuration information other than the target configuration information in the configuration information for the uplink signal sent by the network device.
