Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If semi-persistent scheduling and configured grants are used with multiple occasions, then resource utilization and spectral efficiency are improved, but interference management and duplex processing complexity increase
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting duplex processing configurations based on transmission types. The network node configures different duplex processing parameters (e.g., TDD vs. FDD configurations) for different occasions of semi-persistent scheduling and configured grants, allowing the system to adapt to varying traffic patterns and interference conditions while maintaining efficient resource utilization
Solution Approach 2:
The solution implements dynamics by enabling flexible switching between different duplex processing configurations across multiple occasions. The system can dynamically change the duplex mode (TDD/FDD) and processing parameters based on real-time network conditions, traffic demands, and interference levels, thereby optimizing resource utilization without being constrained by a fixed configuration
2Object-affected harmful factors
If duplex processing configuration is indicated for each occasion, then interference is reduced, but signaling overhead increases
Solution Approach 1:
The patent applies segmentation by dividing the duplex processing configuration into different levels: a default configuration that applies to multiple occasions, and occasion-specific configurations only when needed. This allows the system to reduce interference through targeted configuration indications while minimizing signaling overhead by avoiding redundant transmissions of identical configuration parameters across all occasions
3Adaptability or versatility
If blind detection of duplex transmission type is performed, then adaptability is improved, but processing time and complexity increase
Solution Approach 1:
The patent applies preliminary action by having the network node pre-configure duplex processing parameters and transmission types before actual data transmission. The UE performs blind detection based on these pre-configured parameters, which narrows the search space and reduces processing time compared to completely autonomous detection. This preliminary configuration enables fast adaptation while minimizing detection latency

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a duplex processing configuration associated with a scheduled grant that includes multiple occasions. The UE may process a communication associated with at least one occasion of the multiple occasions based at least in part on the duplex processing configuration. Numerous other aspects are described.
