Terminal Data Prioritization Across Conflicting Device Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where a terminal device needs to communicate with multiple devices simultaneously, there is no clear method for prioritizing data transmission, leading to potential transmission failures of high-latency and high-reliability services like URLLC and TSC, especially during handover procedures.
Innovation Solution
The terminal device determines data for prioritized transmission based on first information, considering resource types, service identifiers, and priority instructions to ensure transmission requirements of special services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device transmits data to multiple devices simultaneously without clear prioritization, then the communication capability is improved, but the transmission reliability of high-latency and high-reliability services deteriorates
Solution Approach 1:
The patent segments the data transmission process by introducing priority levels and resource types. Data is divided into different priority queues (first priority, second priority, etc.), and resources are segmented into different types (retransmitted resources, new transmission resources, configured grant resources). This segmentation allows the terminal device to handle multiple data streams simultaneously while ensuring that high-priority data receives appropriate resource allocation, thus maintaining transmission reliability while supporting multi-device communication.
Solution Approach 2:
The patent changes the parameter of resource allocation by introducing priority-based resource selection. Instead of uniform resource allocation, the system dynamically adjusts resource assignment based on data priority, service type (URLLC, TSC, eMBB), and resource type. This parameter change enables the terminal device to allocate premium resources to critical services while maintaining basic communication capabilities across multiple devices.
2Reliability
If the terminal device uses multiple resource types for prioritized transmission, then the service quality is improved, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple resource types and priority levels before data transmission begins. The terminal device is pre-provisioned with retransmitted resources, new transmission resources, and configured grant resources, each associated with specific priority levels. When data arrives, the device simply matches the data priority with the corresponding pre-configured resources, avoiding complex real-time decision-making and reducing operational complexity while maintaining high service quality.
3Reliability
If the terminal device prioritizes retransmitted resources, then the transmission reliability is improved, but the transmission speed of new data deteriorates
Solution Approach 1:
The patent applies local quality by assigning different resource types to different data priorities and service requirements. Retransmitted resources are specifically allocated for high-reliability data (such as URLLC retransmissions), while new transmission resources and configured grant resources are available for other data types. This localized resource quality assignment ensures that retransmission reliability is improved without blocking new data transmission, as each data type can utilize appropriate resources based on its requirements.

AI summary
Provided are a method for transmitting data, and devices. A method for transmitting data can be provided for a terminal device in the process of maintaining communication between the terminal device and multiple devices. The method comprises: where there is data to be transmitted between the terminal device and a first device and between the terminal device and a second device, and/or an available resource between the terminal device and the first device conflicts with an available resource between the terminal device and the second device, the terminal device determining, according to first information, data for prioritized transmission or a resource for prioritized use; and the terminal device sending the data for prioritized transmission, or, the terminal device sending the data on the resource for prioritized use.
