Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for configuring measurement gap patterns in telecommunication systems like LTE and NR are inefficient, leading to increased measurement latency and delays due to the need for additional signaling and inappropriate parameter changes during bandwidth part switches.
Innovation Solution
A method involving the use of pre-configured measurement gap patterns associated with bandwidth parts, where configuration information and index information are received and utilized to efficiently activate or deactivate measurement gap patterns based on bandwidth part switches, reducing the need for extra signaling and minimizing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gap patterns are re-configured during bandwidth part switches, then measurement accuracy can be maintained, but signaling overhead and configuration latency increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple measurement gap patterns with different parameters (gap lengths, repetition periods, offsets) before bandwidth part switches occur. The network node provides a set of pre-configured measurement gap patterns that the UE can select from during BWP switching, eliminating the need for real-time re-configuration signaling and reducing configuration latency while maintaining measurement accuracy.
Solution Approach 2:
The patent utilizes parameter changes by providing multiple pre-configured measurement gap patterns with varying parameters (MGL, MGRP, gap offset) that can be selected based on the specific bandwidth part being switched to. This allows the system to adapt measurement gap parameters to different BWP characteristics without requiring full re-configuration, thus reducing signaling overhead while maintaining measurement precision.
2Adaptability or versatility
If multiple measurement gap patterns are pre-configured for different bandwidth parts, then configuration flexibility is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the measurement gap configuration into multiple distinct patterns, each optimized for specific bandwidth part characteristics. Instead of creating a single complex adaptive configuration system, the UE is provided with segmented pre-configured patterns that can be independently selected based on the active BWP, simplifying the UE's configuration management while maintaining high adaptability.
Solution Approach 2:
The patent implements universality by designing pre-configured measurement gap patterns that can serve multiple bandwidth parts with similar characteristics. A single pre-configured pattern can be reused across different BWPs, reducing the total number of patterns the UE must manage while maintaining configuration flexibility for diverse BWP scenarios.
3Manufacturing precision
If measurement gap patterns are re-configured during bandwidth part switches, then parameter accuracy is maintained, but signaling overhead increases
Solution Approach 1:
The patent eliminates the need for real-time re-configuration signaling by performing the configuration action preliminarily. Multiple measurement gap patterns with accurate parameters are pre-configured and stored in the UE before bandwidth part switches occur. During BWP switching, the UE simply selects from these pre-configured patterns using minimal indexing information, maintaining parameter accuracy while drastically reducing signaling overhead compared to full re-configuration approaches.
