5G NR Measurement Gap Canceling for Throughput and Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Measurement gaps in wireless communication technologies like 5G NR lead to inefficient pausing in network communication, increasing latency and reducing resource throughput, due to the timing and frequency of these gaps.
Innovation Solution
Implementing measurement gap canceling techniques that adjust operations based on resource conditions, such as UE processing time, using DCI messages to indicate measurement gaps to be canceled, and enabling communication during these gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement gaps are scheduled for UE to perform RRM measurements, then measurement functions can be executed, but network communication is interrupted and resource throughput is reduced
Solution Approach 1:
The patent implements dynamic measurement gap canceling where the network can dynamically indicate to the UE to cancel scheduled measurement gaps through DCI messages. This allows the measurement gap configuration to change dynamically based on current network conditions, transforming a static resource allocation into a flexible one that can adapt to varying throughput requirements.
Solution Approach 2:
The patent changes the operational state parameter of measurement gaps from 'active' to 'canceled' based on network conditions. By introducing a canceling indication mechanism that modifies the gap configuration parameter, the system can switch between performing measurements and maintaining continuous communication based on current priorities.
2Measurement precision
If measurement gaps are frequently scheduled to ensure accurate RRM measurements, then measurement precision is improved, but latency and data interruptions increase
Solution Approach 1:
The patent implements a feedback mechanism where the network monitors UE measurement capabilities and conditions, then provides canceling indications to adjust measurement gap execution. This closed-loop control allows the system to balance measurement precision needs against latency constraints by adapting the measurement schedule based on current network state and UE capabilities.
Solution Approach 2:
Instead of always executing all scheduled measurement gaps, the patent applies partial action by selectively canceling certain gaps when measurements can be deferred without significantly impacting RRM accuracy. This allows the system to perform measurements only when necessary, reducing unnecessary latency while maintaining adequate measurement precision.
3Productivity
If measurement gap canceling is implemented without considering UE processing time, then resource throughput is improved, but errors in gap canceling operations increase
Solution Approach 1:
The patent applies preliminary action by having the network account for UE processing time requirements before issuing measurement gap canceling indications. The network determines whether the UE has sufficient processing time to properly handle the canceling operation, ensuring that canceling commands are sent at appropriate times that allow the UE to process them correctly without causing errors.

AI summary
A system and a method are disclosed for providing measurement gap canceling may be utilized in wireless communication technologies, such as 5G NR technology. Measurement gap canceling may include dynamically modify the timing and/or selection of measurement gaps to be canceled in a manner that can enhance capacity gains of wireless network devices, while limiting an impact to mobility performance. Measurement gap canceling circuitry may be implemented by a network resource (e.g., user equipment (UE) device, base station, etc.) that is configured to determine a measurement gap that may be optimal for canceling based on various conditions (e.g., timing of measurement gap indication(s), processing time for UE device, etc.), and enable transmission/reception communication during the measurement gaps (e.g., canceling the measurement gap) in a manner that may reduce latency in the wireless communication network and improve the overall user experience (e.g., reducing data interruptions) for wireless devices.
