Engineering Contradiction Analysis
1Reliability
If blind detection of multiple PDCCH candidates is performed to ensure reliable decoding, then detection reliability is improved, but computational complexity increases
Solution Approach 1:
The patent applies preliminary action by determining the number of linked PDCCH candidates in advance using a counter mechanism. The counter is initialized to zero and incremented for each linked candidate identified, allowing the system to pre-determine the total number of candidates before performing blind detection. This preliminary counting step enables optimized resource allocation and reduces unnecessary computational operations during the actual decoding process.
2Reliability
If blind detection of multiple PDCCH candidates is performed to ensure reliable decoding, then detection reliability is improved, but resource overhead increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the detection parameters based on the determined number of linked candidates. The counter value obtained from counting linked PDCCH candidates serves as a key parameter that dictates the scope and intensity of blind detection operations. By changing the detection parameters according to this counter value, the system optimizes resource usage while maintaining reliable decoding performance.

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.
