Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If joint transmission or reception of Multiple Transmission and Reception Point (Multi-TRP) is implemented to increase throughput, then system capacity and data rate are improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent segments the monitoring of PDCCH candidates by introducing separate counters for different TRPs. Instead of treating all PDCCH candidates uniformly, the system divides them into groups associated with different transmission points, allowing independent counting and management. This segmentation reduces the complexity of tracking and detecting downlink information across multiple TRPs while maintaining the throughput benefits of joint transmission.
2Measurement precision
If multiple PDCCH candidates are monitored for downlink information detection, then detection accuracy is improved, but processing overhead and resource consumption increase
Solution Approach 1:
The patent introduces dynamic counter mechanisms that adaptively track the number of monitored PDCCH candidates. The counters can be configured to increment or decrement based on detection outcomes and system conditions, allowing the monitoring process to be more efficient. This dynamic approach maintains high detection accuracy by continuing to monitor multiple candidates while reducing unnecessary processing overhead through intelligent counter management.
3Adaptability or versatility
If counters are used to track PDCCH candidates, then resource management is improved, but system complexity increases
Solution Approach 1:
The patent designs counters with multi-functional capabilities that serve multiple purposes within the system. The same counter structure is used across different TRPs and for different types of PDCCH candidates, providing a universal resource management mechanism. This universality improves resource management versatility while avoiding the complexity increase that would result from implementing separate, specialized tracking mechanisms for each scenario.
Data Source
AI summary
A system and method for wireless communication are disclosed herein. Example implementations includes a wireless communication device determining one or more counters for a plurality of linked PDCCH (Physic Downlink Control Channel) candidates, wherein the plurality of linked PDCCH candidates are linked. The one or more counters are numbers of linked PDCCH candidates to be monitored, where each counter is an integer or a decimal. The counters may count individual candidates and/or combined candidates. The counters counting the PDCCH candidates may be the same number of different numbers. The wireless communication device may blindly determine downlink information using the counters and the linked PDCCH candidates.
