Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If antenna panel activation delays are not accounted for in random access procedures, then connection establishment speed is improved, but transmission power determination accuracy deteriorates

Engineering Contradiction:

Improveconnection establishment timeVSAvoidtransmission power determination accuracy

Core Design Contradiction:

Loss of timeVSMeasurement precision

Solution Approach 1:

The patent applies preliminary action by indicating the antenna panel to be used for uplink transmission in advance through control messages before the actual transmission occurs. This allows the wireless device to prepare the appropriate antenna panel and account for activation delays, ensuring accurate transmission power determination while maintaining efficient connection establishment.

Inventive Principle:

Principle #10Preliminary action

2Device complexity

If control signaling is simplified without indicating antenna panel information, then signaling overhead is reduced, but uplink transmission reliability deteriorates

Engineering Contradiction:

Improvecontrol signaling complexityVSAvoiduplink transmission reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent applies universality by using existing control message structures to carry multiple functions - both traditional scheduling information and antenna panel indication. This allows the control signaling to maintain its essential functions while adding antenna panel information, thereby improving uplink transmission reliability without significantly increasing signaling complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Speed

If transmission power is determined without considering antenna panel activation delays, then power determination speed is improved, but uplink signal quality deteriorates

Engineering Contradiction:

Improvepower determination speedVSAvoidsignal quality accuracy

Core Design Contradiction:

SpeedVSMeasurement precision

Solution Approach 1:

The patent replaces the mechanical timing approach with an information-based approach. Instead of relying on fixed timing assumptions that may not account for antenna panel activation delays, the system uses control messages to explicitly indicate the antenna panel to be used. This allows the wireless device to determine transmission power with accurate signal quality consideration while maintaining efficient processing speed through standardized message formats.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A base station and/or a wireless device may perform a communication procedure. A downlink transmission for initiating the communication may indicate an antenna panel for transmission of an uplink signal from the wireless device. A slot for transmission of the uplink signal may be determined based on an antenna panel activation delay.
