Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently providing services, particularly in environments requiring high data rates, low latency, and reliable connectivity, such as those envisioned for 6G systems, due to limitations in carrier selection and quality of service flow management.
Innovation Solution
A method and device for wireless communication that involves obtaining information about multiple carriers and quality of service flows, triggering carrier re-selection based on changes in QoS flows to optimize transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If carrier selection is fixed or static, then device complexity is reduced, but communication efficiency and service quality deteriorate
Solution Approach 1:
The patent implements dynamic carrier selection by triggering carrier re-selection when QoS flow changes occur. The system transitions from static carrier assignment to dynamic adaptation, where carriers are re-selected based on current network conditions and QoS requirements, thereby improving communication efficiency without requiring overly complex manual configuration.
Solution Approach 2:
The patent establishes a feedback mechanism where QoS flow information is continuously monitored and used to trigger carrier re-selection. This feedback loop allows the system to adapt carrier selection based on actual service quality requirements, improving communication efficiency while maintaining manageable complexity through automated decision-making.
2Reliability
If carrier re-selection is frequently triggered, then service quality and reliability improve, but processing time and latency increase
Solution Approach 1:
The system uses QoS flow changes as triggers for carrier re-selection, creating a feedback mechanism that only initiates re-selection when necessary. This conditional approach ensures high service quality and reliability by adapting to actual network conditions while minimizing unnecessary processing time and latency by avoiding frequent or unwarranted re-selection operations.
Solution Approach 2:
The patent changes the parameter of carrier selection based on QoS flow characteristics. By monitoring changes in QoS flows and adjusting carrier selection accordingly, the system achieves high reliability and service quality while controlling processing time through parameter-driven decision-making rather than continuous or frequent re-selection.
3Productivity
If multiple carriers are managed simultaneously, then communication efficiency and data rate improve, but device complexity and control difficulty increase
Solution Approach 1:
The patent segments carrier management by associating specific carriers with specific QoS flows. Instead of managing all carriers uniformly, the system divides carrier management into discrete units linked to individual QoS flows, making the complex task of managing multiple carriers more manageable while maintaining high data rates through selective carrier usage.
Solution Approach 2:
The system implements feedback-based carrier management where QoS flow information guides carrier selection and management decisions. This feedback mechanism simplifies the control of multiple carriers by automatically selecting appropriate carriers based on current QoS requirements, thereby achieving high data rates without proportionally increasing device complexity.

AI summary
Provided are a method by which a first device performs wireless communication and an apparatus supporting same. The method may comprise the steps of: acquiring information regarding a plurality of carriers; acquiring a packet on the basis of a quality of service (QoS) flow; and performing transmission on the basis of at least one carrier from among the plurality of carriers and the QoS flow. For example, carrier reselection for selecting one or more carriers from among the plurality of carriers may be triggered on the basis that the QoS flow is changed.
