Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in achieving reliable inter-radio access technology (IRAT) operations due to unsynchronized or misaligned measurement gaps between different wireless technologies, leading to reduced throughput and connectivity issues.
Innovation Solution
User equipment (UE) devices are equipped with the capability to generate customized or local measurement gaps, extend or shift measurement gap windows, and align control message windows to enhance IRAT operations, including techniques such as creating fake control windows, extending or shifting network measurement gaps, and synchronizing with different radio access technologies.

Engineering Contradiction Analysis
1Reliability
If networks do not support measurement gaps or experience timing misalignments, then inter-RAT measurement operations face challenges in aligning measurement gaps across different wireless technologies, but UE generates customized measurement gaps to align control windows of different radio technologies
Solution Approach 1:
The UE autonomously generates customized measurement gap parameters and configures local measurement gaps without requiring network support or intervention. The UE self-adjusts measurement gap timing to align control windows of different RATs, performing the alignment function independently rather than relying on network-provided configuration.
Solution Approach 2:
The UE modifies measurement gap parameters (timing, duration, positioning) to create customized measurement gaps that align with the specific timing requirements of different RATs. By changing these parameters dynamically, the UE adapts to timing misalignments and clock drift between networks.
2Manufacturing precision
If UE extends or shifts measurement gap windows to align control windows, then timing synchronization between different RATs is improved, but measurement gap configuration becomes more complex
Solution Approach 1:
The measurement gap configuration becomes dynamic rather than static. The UE continuously monitors timing alignment between RATs and adjusts measurement gap positioning and duration in real-time to maintain synchronization, allowing the system to adapt to changing timing conditions.
Solution Approach 2:
The UE performs preliminary alignment calculations and pre-configures measurement gaps to anticipate timing requirements before actual measurements are needed. This proactive approach ensures that measurement windows are properly positioned in advance, reducing the need for complex real-time adjustments.
3Adaptability or versatility
If UE operates in dual wireless modes with customized measurement gaps, then inter-RAT operation reliability is enhanced, but device operation complexity increases
Solution Approach 1:
The measurement gap configuration system becomes multi-functional, serving both single-RAT and dual-RAT operation modes. The same customized measurement gap mechanism works whether the UE is operating on one RAT or simultaneously on multiple RATs, providing universal functionality across different operational scenarios.
Solution Approach 2:
The customized measurement gap acts as an intermediary mechanism that mediates between the timing requirements of different RATs. By introducing this intermediate layer of control, the UE can harmonize conflicting timing demands without requiring complex direct coordination between RATs.
