UE Radio Measurement Validity for Faster Carrier Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless telecommunications networks face challenges in accurately determining the validity of radio interface measurements made by user equipment, particularly in scenarios where the user equipment changes location or orientation, leading to potential delays in reconfiguration and setup of carrier aggregation or dual connectivity.
Innovation Solution
User equipment is configured with measurement validity configurations specifying radio interface characteristics, allowing it to determine whether its measurements meet these criteria and provide valid measurements to the network, potentially adjusting or conducting additional measurements to ensure compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If user equipment performs radio interface measurements to assist in reconfiguration of radio resources, then network reconfiguration can be performed, but unexpected consequences occur including delays and potential measurement invalidity
Solution Approach 1:
The patent applies preliminary action by having the user equipment determine the validity of measurements before reporting them to the network. The UE evaluates whether measurements meet configured validity criteria (such as signal strength thresholds, timing requirements, or location constraints) and only reports measurements that satisfy these pre-established conditions. This prevents invalid measurements from reaching the network, eliminating the need for reconfiguration delays caused by measurement validation failures.
Solution Approach 2:
The patent implements feedback mechanisms where the network provides measurement validity configurations to the user equipment, and the UE reports back both the measurement results and their validity status. The network uses this feedback to make informed reconfiguration decisions. This closed-loop feedback system ensures that only validated measurements drive network reconfiguration, improving both reliability and productivity by avoiding reconfiguration based on invalid data.
2Measurement precision
If user equipment changes location or orientation, then measurement accuracy may be affected, but reconfiguration delays occur
Solution Approach 1:
The patent applies dynamics by making measurement validity criteria adaptive to changing conditions. The network can configure different validity parameters based on UE mobility state, location changes, or orientation variations. When the UE detects location or orientation changes, the system dynamically adjusts the validity evaluation thresholds or requirements, allowing measurements to remain valid under varying conditions without triggering unnecessary reconfiguration delays.
Solution Approach 2:
The patent utilizes parameter changes by modifying measurement validity criteria based on environmental and operational conditions. When location or orientation changes are detected, the system changes parameters such as signal strength thresholds, measurement timing windows, or frequency selection criteria to maintain measurement accuracy. This allows the system to preserve measurement precision under dynamic conditions while avoiding reconfiguration delays that would result from treating all measurement changes as invalid.
