Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless telecommunications systems face challenges in balancing UE measurement performance with power consumption, particularly in scenarios where UE connectivity is maintained through mobile relay nodes.
Innovation Solution
The implementation of a wireless telecommunications apparatus that performs UE measurements only when specific conditions are met, such as time, location, and connection characteristics, thereby reducing unnecessary measurements and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE performs measurements on all network nodes continuously, then measurement performance and connectivity reliability are improved, but UE power consumption increases
Solution Approach 1:
The patent applies dynamics by making the measurement behavior adaptive rather than static. The UE dynamically adjusts its measurement activities based on real-time conditions such as connection state, signal quality, and network node type. Measurements are activated only when needed (e.g., during handover events or when connectivity deteriorates) and deactivated when stable, creating a dynamic balance between reliability monitoring and power consumption.
Solution Approach 2:
The patent changes operational parameters by modifying measurement frequency and scope based on system state. When the UE is in a stable connected state, measurement parameters are reduced (lower frequency, selective nodes). When connectivity threats are detected, parameters are increased (higher frequency, more nodes). This parameter adaptation resolves the contradiction by aligning measurement intensity with actual reliability needs.
2Productivity
If UE performs measurements frequently to maintain optimal connectivity, then link switching and cell reselection performance are improved, but UE power consumption increases
Solution Approach 1:
The patent applies preliminary action by preparing measurement configurations in advance but executing them selectively. The UE pre-configures measurement parameters and maintains awareness of surrounding network nodes, but actually performs measurements only when trigger events occur (e.g., handover decisions, connectivity failures). This allows optimal link switching performance when needed while avoiding continuous measurement power consumption.
Solution Approach 2:
The patent uses feedback mechanisms where the UE monitors connectivity quality and network conditions, then adjusts measurement activities accordingly. When connectivity is stable, feedback indicates reduced measurement activity. When degradation is detected, feedback triggers enhanced measurement and reselection procedures. This feedback loop ensures productivity is maintained only when necessary, reducing unnecessary power consumption.

AI summary
A wireless telecommunications apparatus, forming a UE, for use in a wireless telecommunications network comprises communication circuitry configured to transmit wireless signals to or receive wireless signals from a first network node, the first network node being a mobile network node and control circuitry configured to determine whether one or more conditions are satisfied and when the one or more conditions are satisfied, to measure a characteristic of a wireless signal received by the communication circuitry from a second, different, network node.
