Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If UE performs measurements using all measurement timing occasions with high periodicity, then mobility decision timeliness is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic adaptation of measurement timing occasions based on UE region. The network configures different measurement periodicities and offsets for cell center and cell edge UEs, allowing the measurement configuration to change dynamically according to UE location and radio conditions, thereby optimizing the balance between measurement timeliness and power consumption
Solution Approach 2:
The patent applies different measurement configurations to different spatial regions within the cell. Cell center UEs use one set of measurement timing occasions while cell edge UEs use another set, ensuring that each UE receives a locally optimized configuration suited to its specific radio environment and mobility requirements
2Measurement precision
If UE performs measurements with high periodicity, then measurement precision is improved, but resource management efficiency deteriorates
Solution Approach 1:
The measurement configuration is dynamically adapted based on UE region and radio conditions. The network can adjust measurement periodicity and timing offsets in real-time, allowing high measurement precision when needed (cell edge) while improving resource efficiency when conditions permit (cell center)
Solution Approach 2:
The patent changes key measurement parameters (periodicity, offset, timing occasions) based on UE location. By modifying these parameters dynamically, the system achieves high measurement precision for cell edge UEs while maintaining resource efficiency for cell center UEs with better radio conditions
3Reliability
If measurement configuration is optimized for cell edge conditions, then mobility robustness is improved, but measurement delay increases
Solution Approach 1:
The patent implements location-specific measurement configurations where cell edge UEs receive optimized settings for mobility robustness while cell center UEs receive configurations optimized for lower delay. This local optimization ensures that only UEs who need enhanced mobility robustness experience the associated measurement delays
4Productivity
If UE monitors scheduling information during all measurement timing occasions, then data transmission efficiency is improved, but power consumption increases
Solution Approach 1:
The UE dynamically adapts its monitoring behavior based on the configured measurement timing occasions. By receiving region-specific configurations, the UE can optimize its monitoring schedule to match actual measurement requirements, reducing power consumption during monitoring while maintaining data transmission efficiency

AI summary
Example embodiments of the present disclosure are directed to measurement configuration adaptation. A method comprises receiving, from a second apparatus, a measurement configuration at least comprising a plurality of measurement timing occasions for measurements; performing, based on a state of the first apparatus being in a first region within a cell serving the first apparatus, the measurements by using some of the measurement timing occasions with a first periodicity; and monitoring, during a measurement timing occasion within which the first apparatus does not perform the measurements, scheduling information from the second apparatus; and transmitting, to the second apparatus, a response associated with a reception of a data transmission associated with the scheduling information.
