UE Capability Signaling for MUSIM Measurement Gap Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) supporting multiple subscriber identity modules (MUSIM) faces challenges in managing time-domain conflicts between different measurement gaps in simultaneous network connections, leading to inefficient communication and measurement capabilities.
Innovation Solution
The UE transmits capability information to the network device indicating its measurement capabilities during time-domain conflicts, allowing the network device to configure settings that align with the UE's capabilities, enabling efficient measurement and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE supports multiple measurement gaps for simultaneous network connections, then the measurement capability is improved, but time-domain conflicts occur between different measurement gaps
Solution Approach 1:
The UE feeds back capability information to the network device indicating whether it supports measurement capability when time-domain conflict exists between different measurement gaps. This feedback mechanism allows the network to understand the UE's actual capabilities and configure measurement gaps accordingly, resolving the contradiction by enabling the network to allocate resources that match the UE's measurement capabilities while avoiding unresolvable time-domain conflicts.
Solution Approach 2:
The measurement gap configuration becomes dynamic based on the UE's reported capability. The network device can adjust the measurement gap settings according to whether the UE supports measurement during time-domain conflicts, allowing flexible adaptation of the measurement strategy to the specific UE capabilities and network conditions.
2Ease of operation
If the network device configures measurement gaps without considering UE capability, then configuration simplicity is maintained, but measurement effectiveness deteriorates
Solution Approach 1:
The UE performs preliminary action by reporting its capability information before the network device configures measurement gaps. This advance notification allows the network device to configure measurement gaps that are tailored to the UE's capabilities from the outset, ensuring measurement effectiveness without requiring complex iterative adjustments later.
Solution Approach 2:
The network device changes configuration parameters based on the UE's capability information. When the UE indicates it supports measurement during time-domain conflicts, the network can configure overlapping or closely spaced measurement gaps; when the UE does not support this capability, the network configures measurement gaps that avoid time-domain conflicts, thereby optimizing measurement effectiveness for each UE type.
3Manufacturing precision
If the UE reports detailed capability information, then network configuration accuracy is improved, but communication overhead increases
Solution Approach 1:
The patent extracts only the essential capability information needed for measurement gap configuration - specifically, whether the UE supports measurement capability when time-domain conflict exists. By reporting only this critical parameter rather than comprehensive UE capabilities, the solution achieves sufficient configuration accuracy while minimizing communication overhead.
