Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gap setting information is not provided to terminal, then terminal operation is simple, but terminal cannot perform measurement, MUSIM operation, or transmission power control efficiently
Solution Approach 1:
The gap setting information is segmented into multiple information elements (first information element, second information element) with different structures. Each element contains specific gap parameters (first gap length, second gap length, gap type indicators) that can be independently processed by the terminal, allowing efficient handling of different gap types without overwhelming complexity
Solution Approach 2:
Different information elements provide different levels of gap configuration detail. The first information element provides comprehensive gap settings including first gap length and second gap length, while the second information element provides alternative gap configurations. The terminal can selectively apply appropriate gap settings based on local operational requirements such as measurement needs or MUSIM operation requirements
2Measurement precision
If fixed gap configuration is used, then terminal operation is simple, but measurement accuracy and latency are insufficient
Solution Approach 1:
The system transitions from fixed gap configuration to dynamic gap configuration where the terminal can adjust gap parameters based on operational conditions. The RRCReconfiguration message enables dynamic modification of gap settings, allowing the terminal to optimize measurement accuracy and reduce latency by selecting appropriate gap lengths and types according to current network conditions and service requirements
Solution Approach 2:
The gap configuration parameters (gap length, gap type, timing) are made changeable through the information elements in RRCReconfiguration. The terminal can modify gap parameters such as first gap length, second gap length, and gap timing based on measurement requirements, enabling adaptive optimization of measurement precision and response latency without requiring complex hardware changes
3Adaptability or versatility
If multiple gap types are supported, then terminal adaptability improves, but gap setting complexity increases
Solution Approach 1:
The RRCReconfiguration message structure is designed to be universal, supporting multiple gap types (measurement gap, MUSIM gap, transmission power control gap) through a unified information element framework. The first information element and second information element can both convey gap configuration data, allowing the terminal to handle diverse gap types through a single standardized interface rather than requiring separate configuration mechanisms for each gap type
Solution Approach 2:
Instead of having the terminal request specific gap types and the network responding with customized configurations, the network proactively provides multiple gap configuration options through the RRCReconfiguration message. The terminal receives comprehensive gap setting information including alternative configurations, and can select the most appropriate gap type based on current operational needs, inverting the traditional request-response model to improve adaptability
4Measurement precision
If gap length is increased, then measurement accuracy improves, but transmission latency increases
Solution Approach 1:
The system provides multiple gap length configurations (first gap length, second gap length) with different durations. The terminal can select partial gap lengths when full measurement accuracy is not required, or use longer gap lengths only when measurement precision is critical. This partial action approach allows the terminal to balance measurement accuracy requirements against latency constraints on a case-by-case basis rather than always using maximum gap length
