Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed GI type is used in wireless communication, then system complexity is reduced and implementation is simplified, but adaptability to different communication scenarios and channel conditions deteriorates
Solution Approach 1:
The patent implements dynamic GI type selection where the receiving device determines processing capabilities and selects appropriate GI types (first GI type or second GI type) based on current communication conditions and device capabilities, rather than using a fixed GI type. This allows the system to adapt GI configurations dynamically to different scenarios while maintaining manageable complexity through standardized selection criteria.
2Adaptability or versatility
If flexible GI type selection is implemented, then adaptability to different communication scenarios improves, but device complexity and processing overhead increase
Solution Approach 1:
The patent changes the parameter of GI type (first GI type with longer duration, second GI type with shorter duration) based on processing capability indicators and communication conditions. The system selects between different GI type parameters dynamically, allowing adaptability without requiring completely new system architectures, thus managing complexity while improving versatility.
Solution Approach 2:
The patent applies different GI type configurations to different communication scenarios and channel conditions locally. Rather than changing the entire system configuration, only the GI type parameter is adjusted based on local conditions such as processing capability, channel quality, and traffic type, maintaining overall system simplicity while providing local adaptability.
3Reliability
If longer GI sequences are used, then robustness against multipath interference and signal degradation improves, but communication efficiency and data throughput deteriorate
Solution Approach 1:
The patent dynamically selects between first GI type (longer duration for robustness) and second GI type (shorter duration for efficiency) based on real-time channel conditions and processing capabilities. When channel conditions are poor or multipath interference is high, the system selects the first GI type for robustness; when conditions are good, it selects the second GI type for efficiency, thus balancing reliability and productivity dynamically.
Solution Approach 2:
The patent changes the GI duration parameter between two configured types based on communication conditions. The first GI type has a longer duration providing better protection against interference, while the second GI type has a shorter duration improving efficiency. The system adjusts this parameter dynamically without requiring manual configuration or complex optimization algorithms.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving device may receive, from a first wireless communication device on a first communication channel, a first communication that is configured with at least one guard interval (GI) sequence of a first GI type. The receiving device may receive, from the first wireless communication device or a second wireless communication device on the first communication channel or a second communication channel, a second communication that is configured with at least one GI sequence of a second GI type. Numerous other aspects are described.
