1Productivity

If multiple logical channels are multiplexed into a single transport channel, then resource utilization efficiency is improved, but the complexity of channel management and prioritization increases

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidchannel management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the channel prioritization process into multiple distinct steps: determining priorities for multiple logical channels, selecting a target logical channel based on these priorities, and then multiplexing. This segmentation makes the complex management process more structured and manageable while maintaining high resource utilization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies preliminary action by determining and establishing priorities for multiple logical channels before the actual multiplexing operation. This pre-establishment of priorities simplifies the subsequent multiplexing decision-making process, reducing the complexity during runtime while improving overall resource allocation efficiency.

Inventive Principle:
Principle #10Preliminary action

AI summary

A wireless device may receive, via a first control resource set, coreset, with a first coreset group index, downlink control information, DCI, scheduling a physical downlink shared channel, PDSCH, reception. The wireless device may determine a first quasi co-location-TypeD, QCL-TypeD, of the PDSCH reception is different from a second QCL-TypeD of a physical downlink control channel, PDCCH, reception via a second coreset that overlaps in at least one symbol with the PDSCH reception. The wireless device may also determine the first coreset group index is the same as a second coreset group index of the second coreset. Based on the determinations, the wireless device may prioritize the PDCCH reception via the second coreset.
