Engineering Contradictions & Design Principles

1Reliability

If real-time beam updating is performed through physical signaling, then beam updating reliability is improved, but signaling overhead increases significantly

Engineering Contradiction:

Improvebeam updating reliabilityVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent merges the beam updating signaling with uplink grant signaling by embedding TCI state indication in the uplink grant DCI. This combines two separate signaling functions into one, reducing overall signaling overhead while maintaining reliable beam updating through the grant-based transmission mechanism.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The uplink grant signaling is given multi-functionality by enabling it to indicate both resource allocation and beam (TCI state) information. This universal signaling approach allows a single message to serve multiple purposes, reducing the need for separate dedicated beam updating signals.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Quantity of substance

If higher-layer signaling is used for beam updating, then signaling overhead is reduced, but beam updating speed decreases

Engineering Contradiction:

Improvesignaling overheadVSAvoidbeam updating speed

Core Design Contradiction:

Quantity of substanceVSSpeed

Solution Approach 1:

The patent implements dynamic beam updating by allowing the TCI state to be changed on a per-transmission basis through uplink grant DCI. This dynamic approach enables rapid beam switching without the delays associated with higher-layer signaling reconfiguration, as updates occur at the physical layer timing.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent applies preliminary action by pre-configuring a set of TCI states through higher-layer signaling before actual beam updating is needed. This pre-configuration eliminates the need for real-time higher-layer processing during beam switching, enabling fast updates through simple index selection in the uplink grant.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If multiple beam transmissions are supported, then link robustness is improved, but device complexity increases

Engineering Contradiction:

Improvelink robustnessVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the multiple beam transmissions by associating different TCI states with different uplink grant DCIs. Each grant independently indicates the TCI state for its corresponding transmission, allowing the system to manage multiple beams through separate, simplified control messages rather than complex unified management.

Inventive Principle:

Principle #1Segmentation
