Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single uplink transmission timing is used, then the device complexity is reduced, but the transmission reliability deteriorates due to potential timing conflicts and resource allocation errors

Engineering Contradiction:

Improvetransmission reliabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the uplink transmission timing into multiple separate timing values (first uplink transmission timing and second uplink transmission timing) associated with different reference signals. This segmentation allows the device to handle different transmission scenarios with appropriate timing, improving reliability while managing complexity through structured organization of timing parameters.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic timing selection where the wireless device can adaptively choose between multiple uplink transmission timings based on the specific reference signal being used. This dynamic approach allows the system to optimize timing for each transmission scenario, improving reliability without requiring a fixed complex timing structure.

Inventive Principle:

Principle #15Dynamics

2Productivity

If multiple resources are allocated for uplink transmission, then the transmission efficiency is improved, but the resource management complexity increases

Engineering Contradiction:

Improvetransmission efficiencyVSAvoidresource management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent creates a universal configuration structure where multiple uplink transmission timings and resource sets are defined under a common framework. The base station can configure multiple reference signals, each with associated timing and resource parameters, allowing the system to handle diverse transmission scenarios through a unified configuration approach, improving efficiency while managing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent utilizes parameter-based configuration where different uplink transmission timings and resource allocations are defined through configurable parameters. This allows flexible resource management by changing parameters rather than restructuring the entire system, improving transmission efficiency while keeping resource management complexity manageable through parameterized control.

Inventive Principle:

AI summary

A wireless device may receive configuration parameters from a base station for an uplink transmission via more than one resource and/or timing. The configuration parameters may use different values to instruct the wireless device to use one or more resources (such as first and/or second sounding reference resource sets) for the uplink transmission. The configuration parameters may indicate more than one uplink transmission timing. The wireless device may transmit, during a second time period, portions scheduled to be transmitted during a first time period, for example, if the first time period expires.
