Carrier-Specific Aperiodic Gaps for MUSIM Capability Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing MUSIM devices face challenges in simultaneously maintaining active connections in multiple networks due to limitations in capability sharing and carrier management during RRC connection setups, leading to inefficient resource allocation and increased signaling overhead.
Innovation Solution
Implementing a combination of aperiodic gaps and static capability reduction for MUSIM operations, allowing dual RX/TX devices to share capabilities between networks through carrier-specific gaps, reducing the need for complete carrier releases and minimizing performance impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static capability reduction is used for MUSIM operations, then connection setup in second network is enabled, but carrier throughput and network performance are reduced
Solution Approach 1:
The patent implements dynamic capability sharing where the UE can switch between full capability mode (when only one network is active) and shared capability mode (when MUSIM operation is needed). The gap configuration allows the UE to temporarily suspend carriers in the first network during connection setup in the second network, then resume them afterward, making the capability reduction temporary rather than static.
Solution Approach 2:
The patent uses periodic gap configurations where carriers are temporarily suspended during specific time intervals needed for MUSIM operations. The gap pattern allows the UE to periodically switch between networks without permanently reducing capability, enabling connection setup in the second network while maintaining the ability to restore full throughput afterward.
2Adaptability or versatility
If complete carrier release is performed for MUSIM operation, then connection in second network is established, but signaling overhead increases and connection restoration becomes complex
Solution Approach 1:
Instead of completely releasing carriers for MUSIM operations, the patent applies partial action by configuring gaps that temporarily suspend carrier operation only during the specific time intervals needed for connection setup. This partial suspension allows the UE to establish connection in the second network without triggering full carrier release procedures, thereby reducing signaling overhead while still enabling MUSIM functionality.
3Productivity
If multiple carriers are maintained active simultaneously, then network performance is optimized, but capability sharing between networks becomes difficult
Solution Approach 1:
The patent implements dynamic carrier management where the UE can maintain multiple carriers in a suspended state rather than fully active or fully released. During MUSIM operations, carriers in the first network are temporarily suspended via gap configuration, allowing capability sharing with the second network. After connection establishment, carriers are resumed, restoring full network performance without requiring permanent capability reduction.
