UE Cell Measurement Parameters Based on Mobility State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies do not differentiate UE measurement configurations based on mobility state, leading to inefficient power consumption in stationary or low-mobility UEs due to uniform cell measurement triggering.
Innovation Solution
UEs determine or are configured with first measurement parameters and triggering conditions based on their state, allowing differentiated measurement approaches for power saving, especially in stationary or low-mobility scenarios.

Engineering Contradiction Analysis
1Reliability
If uniform cell measurement triggering is applied to all UEs regardless of mobility state, then measurement coverage is ensured, but power consumption increases for stationary or low-mobility UEs
Solution Approach 1:
The patent segments UEs into different mobility states (stationary, low-mobility, high-mobility) and applies different measurement triggering configurations to each segment. This allows stationary and low-mobility UEs to use relaxed triggering conditions with higher thresholds, reducing unnecessary measurements and power consumption, while high-mobility UEs continue to use uniform triggering to ensure measurement coverage.
Solution Approach 2:
The patent applies local quality by configuring measurement parameters specifically tailored to each UE's mobility state. Stationary and low-mobility UEs receive customized measurement triggering conditions with adjusted thresholds and parameters, while other UEs maintain the uniform configuration, optimizing power consumption locally for specific UE types without affecting overall system performance.
2Use of energy by moving object
If differentiated measurement configurations are provided for UE mobility states, then power saving is achieved for stationary UEs, but device complexity increases
Solution Approach 1:
The patent implements self-service by enabling UEs to autonomously determine their own mobility state and select appropriate measurement triggering configurations from pre-configured options. The UE independently evaluates its mobility characteristics and applies the corresponding measurement parameters, reducing the need for complex network-side management and minimizing configuration overhead.
3Measurement precision
If measurement triggering threshold is lowered for all UEs, then measurement precision is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making measurement triggering thresholds adaptive to UE mobility states. Instead of using fixed thresholds for all UEs, the system dynamically adjusts triggering conditions based on UE mobility characteristics. Stationary and low-mobility UEs use higher thresholds to reduce triggering frequency, while maintaining the capability for precise measurement when conditions warrant it, thereby balancing measurement precision with power consumption.

AI summary
A measurement method, a user equipment and a network side device are provided. The measurement method performed by the user equipment includes: determining a first measurement parameter; determining whether a measurement triggering condition is met; and performing measurement on at least one of a neighboring cell of the UE or a serving cell of the UE based on the first measurement parameter, in a case that the measurement triggering condition is met.
