Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple sets of transmission configuration indicator states are maintained for different downlink control information formats, then the adaptability to different communication standards is improved, but the device complexity increases

Engineering Contradiction:
Improveadaptability to different communication standardsVSAvoidcomplexity of managing multiple state sets
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the transmission configuration indicator states into multiple distinct sets, where each set is specifically tailored for a particular downlink control information format. This segmentation allows the system to maintain specialized state configurations for different communication standards without requiring a single complex unified state management mechanism, thereby improving adaptability while managing complexity through modular organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic selection mechanisms that allow the system to switch between different sets of transmission configuration indicator states based on the active downlink control information format. This dynamic approach enables the system to adapt its state management behavior in real-time according to communication requirements, improving versatility while maintaining operational simplicity through context-dependent state selection.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the number of transmission configuration indicator states is increased to cover more communication scenarios, then the versatility is improved, but the loss of time for state selection and management increases

Engineering Contradiction:
Improvecoverage of communication scenariosVSAvoidtime for state selection and management
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent performs preliminary organization of transmission configuration indicator states by pre-configuring distinct sets for different downlink control information formats. This preliminary action ensures that when a specific communication scenario arises, the appropriate state set is already prepared and readily accessible, eliminating the need for time-consuming state selection and management operations during active communication.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies local quality by configuring specific transmission configuration indicator states with properties optimized for particular communication scenarios. Each set of states is locally optimized for its designated downlink control information format, allowing rapid selection based on the current communication context without requiring comprehensive evaluation of all possible states, thus reducing state management time while maintaining scenario coverage.

Inventive Principle:
Principle #3Local quality

AI summary

A method and apparatus are provided, in which an activation command is received, which indicates a first set of transmission configuration indicator (TCI) states to select between, which are to be used with transmissions scheduled using a first downlink control information (DCI) format. A number of states included in the first set corresponds to a selection field associated with the first DCI format having a first size. A second set of TCI states to select between, which are to be used with transmissions scheduled using a second DCI format is determined. A number of states included in the second set corresponds to a selection field associated with the second DCI format having a second size, where the second size is different than the first size. Transmissions scheduled using the second DCI format are received.
