Measurement Gap Capability Signaling Across Frequency Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in managing measurement gaps due to limitations in baseband capabilities, leading to excessive signaling overhead when switching between per-UE and per-FR measurement gap configurations, particularly when UE baseband capacity is saturated.
Innovation Solution
Implementing methods for a UE to indicate specific CC limits and maximum aggregated bands or FRs where per-FR measurement gaps are infeasible, allowing the network to schedule per-UE gaps instead, thereby reducing signaling overhead by minimizing individual fallback band combination indications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If per-UE measurement gap configuration is used, then measurement can be performed, but signaling overhead increases excessively when baseband capacity is saturated
Solution Approach 1:
The patent introduces a new parameter - CC limit indication - that changes the way measurement gap configuration is managed. Instead of always using per-UE configuration which causes excessive signaling, the system can switch to per-FR configuration when CC limit is reached, thereby reducing signaling overhead while maintaining measurement capability.
Solution Approach 2:
The patent makes the measurement gap configuration dynamic by allowing the UE to indicate when per-FR configuration should be used instead of per-UE configuration. This dynamic adaptation based on baseband capacity utilization resolves the contradiction between reliable measurement and reduced signaling overhead.
2Loss of information
If per-FR measurement gap configuration is used, then signaling overhead is reduced, but baseband capacity saturation may occur
Solution Approach 1:
The patent implements a feedback mechanism where the UE indicates its baseband capacity status and CC limit to the network. This feedback allows the network to adapt the measurement gap configuration accordingly, preventing baseband saturation while maintaining low signaling overhead through per-FR configuration when appropriate.
Solution Approach 2:
The patent uses parameter changes by introducing CC limit indication and maximum aggregated bands parameter to manage baseband capacity. These parameters enable the system to detect when per-FR configuration is sufficient and when per-UE configuration is needed, balancing signaling overhead reduction with baseband capacity protection.
3Productivity
If UE indicates specific CC limits and maximum aggregated bands, then scheduling efficiency improves, but device complexity increases
Solution Approach 1:
The patent segments the UE capability indication into distinct parameters - CC limit indication and maximum aggregated bands - rather than requiring a complete capability description. This segmentation simplifies the indication mechanism while maintaining scheduling efficiency, as the network only needs to process these specific parameters to make informed scheduling decisions.

AI summary
Systems and methods for indications and determinations related to the use of per-frequency range (FR) measurement gap procedures or per-user equipment (UE) measurement gap procedures are disclosed herein. A UE may inform a base station when it is infeasible for the UE to perform per-FR measurement gap procedures with a particular band combination configured to the UE. A CE may alternatively or additionally determine and indicate, to the base station: one or more CC limits, a maximum number of aggregated bands across all FRs, a maximum number of aggregated bands in a particular FR, and/or a maximum number of FRs for which a per-FR measurement gap procedure is supported at the UE. A base station may use one or more of these values to determine whether the UE will use per-FR or per-UE measurement gap procedures with a configured band combination (and/or with a corresponding fallback band combination).
