PDCCH Decoding Order for Same-Symbol DCI Endings

The patent applies preliminary action by determining the decoding order of multiple DCIs before actual decoding occurs. The base station configures the UE with a predefined decoding order based on properties of the DCIs (such as priority levels, service types, or QoS parameters) before the DCIs are transmitted. This preliminary determination of decoding sequence prevents interference between simultaneous decodings while maintaining efficient processing, as the UE knows in advance which DCI to decode first when multiple DCIs end at the same symbol.

The patent applies local quality by establishing different minimum distance thresholds for different DCI-PDSCH pairs based on their specific properties. Instead of using a uniform threshold, the base station determines individual minimum distances for each DCI-to-PDSCH association, considering factors such as DCI priority, service type (e.g., URLLC vs. eMBB), and channel conditions. This allows the system to reduce the minimum distance for high-priority or robust services to improve spectral efficiency, while maintaining larger distances for services requiring higher reliability, thus optimizing both spectral efficiency and transmission reliability locally for each traffic flow.
