Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple resource sets and transmission configuration indicator states are configured for a cell, then adaptability and communication flexibility are improved, but information scheduling becomes incompatible and interference increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple resource sets and transmission configuration indicator states before communication occurs. The wireless device receives configuration parameters that include multiple resource sets (e.g., CORESETs) and TCI states in advance, allowing it to prepare multiple communication paths and select the most appropriate one based on current channel conditions, thereby improving adaptability while maintaining scheduling compatibility.
Solution Approach 2:
The patent implements dynamics by enabling the wireless device to dynamically select among multiple pre-configured resource sets and TCI states based on real-time scheduling information. The device can switch between different resource sets and activate different TCI states according to channel quality, interference levels, and scheduling decisions, allowing the system to adapt to changing conditions without creating interference.
2Device complexity
If incompatible scheduling information is used, then device complexity is reduced, but error rates increase and reliability deteriorates
Solution Approach 1:
The patent applies parameter changes by modifying the scheduling information parameters to ensure compatibility with the configured resource sets and TCI states. The base station adjusts scheduling parameters such as resource allocation, modulation and coding schemes, and TCI state indicators to match the pre-configured settings, thereby maintaining communication reliability without increasing device complexity.
3Object-affected harmful factors
If default resource set and TCI state are used to ensure compatibility, then interference is reduced, but data rates may be limited
Solution Approach 1:
The patent implements dynamics by allowing the wireless device to switch between default and non-default resource sets and TCI states based on channel conditions. When channel quality is good and interference is low, the device can activate alternative resource sets and TCI states to achieve higher data rates. When conditions deteriorate, it falls back to the default configuration, thus balancing interference reduction with data rate optimization.
Solution Approach 2:
The patent applies preliminary action by pre-configuring multiple resource sets with different characteristics (e.g., different bandwidths, numerologies, or beam directions) before communication begins. This allows the system to select the most appropriate resource set for the current conditions, achieving both interference reduction through careful selection and high data rates through optimal resource utilization.

AI summary
A wireless device may be configured to communicate via a set of cells. A communication via a cell, of the plurality of cells, may be scheduled. A single communication point operation/mode may be indicated for the cell. The wireless device may receive information for selecting from multiple resource sets and/or multiple transmission configuration indicator states for communicating via the cell. A default resource set and/or transmission configuration indicator state may be used in the scheduled communication based on the single communication point operation/mode.
