Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in performing wireless signal transmission and reception procedures, particularly in managing radio resource measurements for user equipment (UE) in diverse mobility states, leading to increased power consumption and potential performance degradation.
Innovation Solution
The method involves transmitting information about the UE's mobility state, receiving configuration information for cell measurement, and performing relaxed radio resource management (RRM) measurements by skipping certain synchronization signal block (SSB) indexes or neighboring cells, based on predetermined thresholds and indications from the base station, to optimize measurement efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE performs RRM measurement for all SSB indexes and neighboring cells, then measurement precision is improved, but power consumption increases
Solution Approach 1:
The patent segments the measurement process by dividing SSB indexes into two groups: a first SSB index with higher measurement quality and second SSB indexes with lower measurement quality. The UE performs RRM measurement only on the first SSB index, segmenting the measurement task to reduce power consumption while maintaining measurement precision for the most relevant cell.
Solution Approach 2:
The patent applies local quality by measuring different SSB indexes with different qualities based on their measurement results. The UE identifies the first SSB index with higher measurement quality and focuses measurement resources on that specific index, rather than uniformly measuring all SSB indexes, thereby optimizing the balance between measurement precision and power consumption.
2Measurement precision
If the UE performs RRM measurement for all neighboring cells, then measurement precision is improved, but measurement efficiency deteriorates
Solution Approach 1:
The patent segments neighboring cells into two categories: serving cell and non-serving neighboring cells. The UE performs RRM measurement on the serving cell's first SSB index but skips RRM measurement on second SSB indexes of non-serving neighboring cells. This segmentation improves measurement efficiency by focusing resources on the most critical measurements while maintaining sufficient precision through selective measurement.
Solution Approach 2:
The patent applies partial action by performing RRM measurement only on the first SSB index of the serving cell rather than on all SSB indexes of all neighboring cells. This partial measurement approach achieves adequate measurement precision for mobility management while significantly improving measurement efficiency by reducing the total number of measurements performed.
3Use of energy by moving object
If the UE performs relaxed RRM measurement by skipping certain SSB indexes, then power consumption is reduced, but measurement precision may deteriorate
Solution Approach 1:
The patent ensures measurement precision is maintained by identifying and measuring the first SSB index with higher measurement quality. By focusing measurement resources on the SSB index with superior quality rather than uniformly measuring all SSB indexes, the patent achieves adequate measurement precision for mobility management while reducing power consumption through selective measurement.
Solution Approach 2:
The patent uses measurement quality feedback to determine which SSB index to measure. The UE measures SSB indexes, evaluates their measurement qualities, and uses this feedback to identify the first SSB index with higher quality for RRM measurement. This feedback mechanism ensures that measurement precision is maintained by always measuring the most relevant SSB index while avoiding unnecessary measurements of lower-quality indexes.
