Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If full-duplex capable UE uses unified transmission parameters for both half-duplex and full-duplex modes, then device complexity is reduced, but resource utilization efficiency deteriorates and latency increases

Engineering Contradiction:

Improvetransmission parameter configurationVSAvoidresource utilization efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent segments the transmission parameter configuration into mode-specific configurations. Separate configurations are provided for half-duplex and full-duplex modes, allowing each mode to have optimized parameters tailored to its specific operational characteristics, thereby improving resource utilization efficiency without excessive complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic configuration where the UE can switch between different transmission parameter sets based on the operational mode (half-duplex or full-duplex). This dynamic adaptation allows the system to optimize performance for each mode while maintaining manageable complexity through automated mode detection and configuration selection

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If full-duplex capable UE uses unified transmission parameters for both half-duplex and full-duplex modes, then ease of operation is improved, but latency increases and power consumption increases

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

By segmenting parameters into mode-specific configurations, the system eliminates unnecessary parameter adjustments and mode switching delays, reducing latency while maintaining ease of operation through automated configuration selection based on detected operational mode

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If full-duplex capable UE uses unified transmission parameters for both half-duplex and full-duplex modes, then ease of operation is improved, but power consumption increases

Engineering Contradiction:

Improvetransmission parameter configurationVSAvoidpower consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

Mode-specific parameter configurations enable optimized power management by selecting appropriate transmission parameters for each operational mode, reducing unnecessary power consumption while maintaining ease of operation through automated configuration based on mode detection

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent changes transmission parameters dynamically based on the operational mode. By adjusting parameters such as transmission power, timing, and resource allocation according to whether the UE is operating in half-duplex or full-duplex mode, the system optimizes power consumption while keeping the user experience simple

Inventive Principle:

4Device complexity

If full-duplex capable UE transmits in all allocated slots without mode-specific configurations, then device complexity is reduced, but resource utilization efficiency deteriorates

Engineering Contradiction:

Improvetransmission control logicVSAvoidresource utilization efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent segments the transmission control logic into mode-specific handling. Separate control flows are implemented for half-duplex and full-duplex modes, enabling optimized resource utilization for each mode while keeping the overall system manageable through structured separation of control logic

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system incorporates feedback mechanisms where the UE reports its operational mode to the network, which then provides appropriate configured grants with mode-specific parameters. This feedback loop enables optimized resource allocation without requiring complex autonomous decision-making at the UE level

Inventive Principle:

Principle #23Feedback

AI summary

Methods, systems, and devices for wireless communication are described. For example, a user equipment (UE) may receive a grant indicating one or more resources allocated to the UE for uplink transmission. These one or more resources may include one or more half duplex slots and one or more full duplex slots. The UE may receive an indication of at least one configuration associated with the one or more half duplex slots, the one or more full duplex slots, or both. For instance, the at least one configuration may indicate a set of parameters that correspond to the one or more half duplex slots, the one or more full duplex slots, or both. Subsequently, the UE may transmit one or more uplink messages based on the at least one configuration.
