Adaptive Measurement Report Timing for 5G NSA Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-standalone wireless communication devices experience excessive battery drainage and increased air-interface interference due to frequent signal strength measurements and reports when attempting to attach to a 5G new radio (NR) base station, as they continuously measure signal strength until meeting the B1 threshold, leading to inefficient power usage and potential missed attachment opportunities.
Innovation Solution
Implementing an adaptive scheduling mechanism for signal strength measurements and reports, using a two-to-the-power-of-N pattern to skip measurement points, allowing the device to adjust the reporting frequency based on the absence of an RRC reconfiguration message, thereby reducing unnecessary measurements and reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communication device continuously performs periodic NR signal strength measurements and sends measurement reports to meet the B1 threshold, then the device can successfully attach to the NR base station, but the battery becomes hot and power is quickly drained
Solution Approach 1:
The patent implements a periodic measurement schedule where the device performs NR signal strength measurements at predetermined intervals (e.g., every 8 measurements or 120 milliseconds) rather than continuously. This periodic action reduces the frequency of measurements and reports while still allowing the device to detect when the B1 threshold is met, thereby reducing power consumption while maintaining attachment capability.
Solution Approach 2:
The patent applies partial action by performing only a subset of the full measurement schedule. Specifically, the device performs measurements at predetermined intervals (e.g., every 8th measurement point) rather than at every possible measurement opportunity. This partial execution of the measurement sequence reduces overall power consumption while still achieving the attachment objective when signal conditions are favorable.
2Reliability
If the wireless communication device continuously sends measurement reports about NR signal strength, then the device can attach to the NR base station, but air-interface interference increases
Solution Approach 1:
The patent reduces air-interface interference by implementing periodic measurement reporting where the device sends NR signal strength reports only at predetermined intervals (e.g., every 8th measurement) rather than continuously. This periodic reporting approach maintains the ability to notify the network when attachment conditions are met while significantly reducing the volume of uplink traffic and associated interference on the air interface.
Solution Approach 2:
The patent applies partial action by transmitting measurement reports only at selected intervals rather than at every measurement opportunity. The device performs measurements continuously but reports only periodically (e.g., every 8th measurement point), thereby reducing the frequency of uplink transmissions and minimizing air-interface interference while still achieving timely attachment when signal conditions are favorable.
3Speed
If the device performs frequent measurements and reports, then the device can quickly detect when the B1 threshold is met, but the number of measurements and reports becomes quite large
Solution Approach 1:
The patent implements periodic measurement and reporting at predetermined intervals (e.g., every 8th measurement or every 120 milliseconds) rather than continuous measurement. This approach maintains adequate threshold detection speed by checking signal strength regularly at intervals that balance responsiveness with efficiency, while significantly reducing the total number of measurements and reports compared to continuous monitoring.
Solution Approach 2:
The patent applies partial action by performing measurements at a reduced frequency - specifically at predetermined intervals such as every 8th measurement point rather than at every possible measurement opportunity. This partial execution of the measurement sequence maintains sufficient speed for detecting threshold conditions while dramatically improving measurement efficiency by reducing the overall volume of measurements and reports generated.

AI summary
Systems and methods discussed herein are directed to adapting signal strength measurement and corresponding signal strength measurement report scheduling for attaching an electronic device configured as a non-standalone (NSA) device to a new radio (NR) base station of a wireless communication network, e.g., a base station configured according to 5G operating protocols. In particular, an initial schedule for signal strength measurement and corresponding signal strength measurement reporting for attaching the electronic device to the NR base station may be adapted or altered, according to a predetermined pattern. For example, the pattern may be a two to the power of N based pattern.
