Existing wireless communication systems face challenges in efficiently providing services, particularly in advanced systems like 6G, which require high data rates, low latency, and reliable connectivity, especially in scenarios involving vehicle-to-everything (V2X) communications.
Innovation Solution
A method and device for wireless communication that involves obtaining and transmitting information related to multiple carriers based on quality of service (QoS) flows, utilizing a vehicle-to-everything (V2X) layer, and employing advanced technologies such as AI, THz communication, and UAVs to enhance connectivity and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple carriers are used for transmission, then data rate and connectivity are improved, but device complexity and network management difficulty increase
Solution Approach 1:
The patent segments the transmission process by associating different QoS flows with specific carriers through QoS flow-to-carrier mapping. Each QoS flow can be independently mapped to appropriate carriers based on service requirements, allowing the system to handle multiple carriers in a modular, organized manner that reduces complexity while maintaining high data rates
Solution Approach 2:
The patent implements a universal QoS flow-to-carrier mapping mechanism that can accommodate different service types and carrier configurations through a single framework. This multi-functional approach allows the same mapping mechanism to serve various QoS requirements across multiple carriers without requiring separate handling logic for each scenario
2Reliability
If QoS flow-based carrier selection is implemented, then service reliability is improved, but processing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing QoS flow-to-carrier mapping relationships before actual data transmission. The mapping configuration is prepared in advance based on QoS requirements, allowing packets to be rapidly routed according to pre-determined rules rather than making complex decisions in real-time, thus improving reliability while minimizing processing complexity during transmission
3Productivity
If advanced technologies like AI and THz communication are integrated, then connectivity and data rate are enhanced, but energy consumption and device complexity increase
Solution Approach 1:
The patent implements partial action by selectively applying advanced technologies only where needed based on QoS requirements. Not all QoS flows require AI processing or THz communication capabilities - the system applies these advanced features only to specific flows that demand high performance, while using simpler mechanisms for other flows, thereby reducing overall energy consumption while maintaining high data rates for critical services

AI summary
Provided are a method for performing wireless communication by a first device, and a device for supporting same. The method may comprise the steps of: acquiring information about a plurality of carriers; acquiring a packet on the basis of a qualify of service (QoS) flow; and transmitting on the basis of one or more carriers related to the QoS flow among the plurality of carriers. For example, information about at least one carrier per QoS flow can be provided from a vehicle-to-everything (V2X) layer of a first device.
