Solution Overview
Problem
In Industrial IoT (IIoT) wireless communication systems, the handling of measurement gaps during a survival time state is not effectively managed, leading to potential data transmission disruptions and errors in critical manufacturing environments.
Innovation Solution
A first wireless communication device and a second wireless communication device are configured to control wireless measurement and data transmission prioritization, allowing the second device to adjust measurement gap performance and timing, ensuring data arrival within a survival time limit by including measurement-related information in control signals and prioritizing data transmission during the survival time state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless measurement is performed during survival time state, then measurement accuracy is improved, but data transmission reliability deteriorates due to potential disruptions
Solution Approach 1:
The patent dynamically adjusts measurement gap configuration during survival time state based on data transmission requirements. The base station determines whether to perform wireless measurement by evaluating the survival time state and measurement gap timing, making the measurement process adaptive rather than static. This resolves the contradiction by making measurement accuracy contingent on transmission reliability conditions.
Solution Approach 2:
The patent performs preliminary assessment of survival time state before initiating wireless measurement. The base station determines the survival time state in advance and configures measurement gaps accordingly, ensuring that measurement activities are planned ahead to avoid disrupting critical data transmissions. This preliminary action prevents measurement-induced transmission disruptions.
2Adaptability or versatility
If measurement gap is configured during survival time state, then wireless measurement capability is improved, but data transmission continuity deteriorates
Solution Approach 1:
The patent applies local quality by configuring measurement gaps only in specific time locations that do not conflict with data transmission requirements. The base station determines appropriate measurement gap timing based on the survival time state, placing measurement activities in time slots where they will not interrupt critical transmissions. This localized configuration maintains measurement capability while preserving transmission continuity.
Solution Approach 2:
The patent dynamically configures measurement gap parameters including timing and duration based on the current survival time state. When survival time is critical, measurement gaps are minimized or eliminated; when survival time allows, measurement capability is enhanced. This dynamic adjustment resolves the contradiction between measurement versatility and transmission continuity.
3Reliability
If data transmission priority control is implemented during survival time state, then data arrival reliability is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service priority control where the base station autonomously determines survival time state and configures appropriate priority levels for data transmission without requiring complex external coordination. The system serves itself by internally managing priority assignments based on survival time conditions, reducing overall system complexity while maintaining high data arrival reliability.
Solution Approach 2:
The patent changes transmission parameter priorities dynamically based on survival time state. When survival time is critical, high-priority parameters are applied to ensure timely delivery; when survival time allows, normal priority parameters are used. This parameter-based approach simplifies the control mechanism compared to more complex priority management systems.
