Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In new radio (NR) systems, terminal devices face challenges in transmitting application layer data units (ADUs) effectively, particularly in ensuring synchronized processing and meeting transmission requirements for associated ADUs, which affects data transmission quality and user experience.
Innovation Solution
A method and device configuration that allows terminal devices to receive and process information related to ADUs from network devices, enabling them to perform transmission, stop transmission, or delete packets based on configuration parameters and indications, ensuring synchronized processing and meeting overall service transmission requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If terminal devices transmit ADUs independently without centralized coordination, then transmission speed increases, but transmission quality and synchronization deteriorate
Solution Approach 1:
The network device performs preliminary actions by determining transmission requirements for multiple associated ADUs before transmission begins, and sends these requirements to the terminal device in advance. This allows the terminal device to transmit ADUs independently at high speed while the network device ensures transmission quality through centralized coordination and quality control based on pre-determined requirements.
2Adaptability or versatility
If terminal devices process each ADU individually, then processing flexibility increases, but synchronized processing of associated ADUs deteriorates
Solution Approach 1:
The network device merges the processing of multiple associated ADUs by determining transmission requirements for multiple ADUs together rather than individually. It sends unified transmission requirements to the terminal device, enabling the terminal to process each ADU flexibly while maintaining synchronized processing through centralized coordination at the network level.
3Device complexity
If no transmission requirements are specified, then device complexity decreases, but ability to meet service transmission requirements deteriorates
Solution Approach 1:
The network device acts as an intermediary by determining transmission requirements for multiple associated ADUs and sending these requirements to the terminal device. This intermediary approach allows the terminal device to remain relatively simple while still being able to meet specific service transmission requirements through the guidance provided by the network device.
