Sidelink Bearer Splitting With PDCP-RLC Mapping for Multi-Carrier Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In New Radio (NR) systems, the correct scheduling of data transmission over multiple carriers using different radio access technologies, such as LTE and NR sidelinks, is not clearly defined, leading to challenges in ensuring accurate reception of data by reception terminals.
Innovation Solution
The proposed solution involves enabling a bearer-splitting transmission mode for radio bearers over multiple carriers, associating a PDCP entity with multiple RLC entities, and ensuring consistent understanding of this relationship between transmission and reception terminals through various signaling methods, including control-plane and user-plane signaling, to facilitate correct data reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data is stored locally in terminal devices, then data access speed is improved, but data security deteriorates due to device loss or theft
Solution Approach 1:
The patent introduces a distributed file system as an intermediary layer between terminal devices and storage devices. This file system manages data storage and retrieval across multiple devices, providing secure access control and encryption while maintaining fast access speeds. The intermediary abstracts the complexity of distributed storage from users, enabling secure cloud-based storage with user-friendly access.
2Reliability
If data is stored in the cloud, then data security is improved, but data access speed deteriorates due to network dependency
Solution Approach 1:
The patent segments data into multiple parts and distributes them across different terminal devices in the cloud network. This segmentation allows parallel retrieval of data parts from multiple devices simultaneously, significantly improving access speed while maintaining the security benefits of distributed cloud storage. The file system reconstructs the complete data from the segmented parts.
3Reliability
If distributed storage is implemented, then data security and reliability are improved, but system complexity increases
Solution Approach 1:
The patent implements a universal distributed file system that can operate across various terminal devices (smartphones, tablets, computers, storage devices) with different hardware configurations. This multi-functional file system provides a unified interface and management mechanism for distributed storage, simplifying the user experience while maintaining the reliability benefits of distributed architecture across diverse device types.
