Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measuring nodes attempt to measure signals at pre-scheduled measurement occasions in dynamic scheduling environments, then measurement coverage is improved, but measurement accuracy deteriorates due to uncertain measurement occasions where signals have not been transmitted
Solution Approach 1:
The patent applies preliminary action by having the network node provide measurement occasion information to the measuring node before the actual measurement takes place. This allows the measuring node to prepare and know in advance which measurement occasions are valid, preventing wasted measurements on occasions where signals will not be transmitted. The measurement occasion information acts as a pre-arranged schedule that ensures measurement reliability.
Solution Approach 2:
The patent implements feedback by having the network node provide measurement occasion information to the measuring node, creating a feedback loop where the network communicates scheduling decisions back to the measuring entities. This feedback mechanism ensures that measuring nodes have accurate information about when signals will be transmitted, resolving the uncertainty in measurement occasions and improving both reliability and precision.
2Productivity
If measuring nodes perform measurements at all pre-scheduled occasions, then measurement quantity is improved, but resource efficiency deteriorates due to wasted measurements on uncertain occasions
Solution Approach 1:
The network node provides measurement occasion information in advance to the measuring node, enabling the measuring node to identify and skip uncertain measurement occasions before attempting measurements. This preliminary information prevents wasted measurement resources on occasions where signals will not be transmitted, improving resource efficiency while maintaining necessary measurement throughput.
Solution Approach 2:
The patent applies discarding and recovering by having the measuring node discard (skip) uncertain measurement occasions where signals are not transmitted, rather than performing futile measurements. By identifying these occasions in advance through measurement occasion information, the system recovers measurement resources that would otherwise be wasted, allowing those resources to be used more effectively elsewhere.

AI summary
A method is provided for configuring measurements performed by wireless communication devices. The method includes obtaining, at a first wireless communication device, information identifying a plurality of measurement occasions in which a second wireless communication device is scheduled to transmit a measurement signal to be used by the first wireless communication to perform a first measurement. The method also includes obtaining, at the first wireless communication device, information indicating one or more measurement gaps associated with the second wireless communication device in which the second wireless communication device is configured to perform a second measurement and adjusting measurements performed by the first wireless communication device based on the obtained information indicating one or more measurement gaps.
