Bandwidth Part Selection for Multi-Subscription UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in managing bandwidth part selection for multi-subscriber user equipment, leading to interference and reduced communication quality due to frequency overlaps between different subscriptions.
Innovation Solution
A method where user equipment determines frequency overlaps between transmissions associated with different subscriptions and requests a new bandwidth part configuration from the base station based on satisfying specific conditions, such as threshold bandwidth, to minimize interference and improve communication reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE uses multiple bandwidth parts for different subscriptions, then communication capability is improved, but frequency overlap and interference occur
Solution Approach 1:
The patent implements dynamic bandwidth part selection where the UE monitors frequency overlap conditions and switches between different bandwidth part configurations based on real-time interference detection. The system transitions from static bandwidth allocation to dynamic adaptation, selecting bandwidth parts that minimize interference while maintaining communication capability across multiple subscriptions.
Solution Approach 2:
The patent changes the bandwidth part parameters (frequency range, bandwidth allocation) based on detected interference conditions. When frequency overlap is detected between subscriptions, the system modifies the bandwidth part configuration parameters to eliminate or reduce the overlap, thereby resolving the contradiction between maintaining multi-subscription capability and avoiding interference.
2Reliability
If the UE monitors frequency overlap continuously, then communication quality is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the UE monitors frequency overlap conditions and provides feedback to itself (internal monitoring) to trigger bandwidth part switching. The monitoring is performed selectively based on predefined conditions rather than continuously, reducing complexity while maintaining communication quality through condition-driven feedback loops.
Solution Approach 2:
The UE performs self-monitoring of frequency overlap conditions and autonomously determines when to switch bandwidth parts without requiring continuous external network control. This self-service approach reduces the complexity of network-side monitoring while maintaining communication quality through the UE's own resource management capabilities.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a frequency overlap between a first transmission, with a first base station associated with a first subscription of the UE, on a first bandwidth part, and a second transmission, with a second base station associated with a second subscription of the UE, on a second bandwidth part. The UE may transmit, to the second base station, a request for a new bandwidth part for the second subscription, based at least in part on the frequency overlap satisfying a condition. Numerous other aspects are provided.
