Rate-Split Communication Scrambling for Common Message Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rate-splitting techniques in communication systems face challenges in ensuring that data scrambled with user-specific identifiers can be successfully processed by multiple users, as the common part of the message is not compatible with user-specific scrambling.
Innovation Solution
A method involving splitting individual messages into common and private parts, combining these parts for a group of devices, and using a common group identifier for scrambling the common message, which is known to all devices in the group, along with unique device-specific identifiers for private parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user-specific identifiers are used for scrambling data, then security and user-specific processing are improved, but compatibility with common messages shared by multiple users deteriorates
Solution Approach 1:
The message is segmented into two distinct parts: a common part that is scrambled using a common identifier shared by multiple users, and a private part that is scrambled using user-specific identifiers. This segmentation allows each part to be processed appropriately - the common part can be decoded by any user in the group while the private part maintains user-specific security and processing.
Solution Approach 2:
Different scrambling methods are applied to different parts of the message based on their specific requirements. The common part uses common identifier-based scrambling to ensure accessibility by all group members, while the private part uses user-specific identifier-based scrambling to maintain individual security. This local differentiation of quality resolves the contradiction between common compatibility and user-specific reliability.
2Adaptability or versatility
If a common identifier is used for scrambling the common message, then descrambling compatibility across multiple devices is improved, but user-specific security for private parts deteriorates
Solution Approach 1:
The message structure is divided into common and private segments, each with their own scrambling approach. The common segment uses a common identifier for scrambling, ensuring that all devices in the group can successfully descramble and access this portion. The private segment uses user-specific identifiers, maintaining security and reliability for individual users. This segmentation allows both requirements to coexist without conflict.
Solution Approach 2:
The common identifier-based scrambling mechanism serves as a universal solution for the common message portion, enabling all users in the group to access shared information. Meanwhile, the user-specific identifier mechanism provides individualized security for private content. The system thus achieves multi-functionality, handling both common and private communication requirements effectively.
3Measurement precision
If individual messages are processed separately with user-specific scrambling, then user-specific processing accuracy is improved, but efficiency of common information transmission deteriorates
Solution Approach 1:
The common parts of multiple individual messages are merged into a single common message that is transmitted once to all users in the group. This common message is scrambled using a common identifier, allowing all users to efficiently receive and process the shared information simultaneously. The private parts remain separate and are processed individually with user-specific scrambling, maintaining processing accuracy. This merging approach significantly improves transmission efficiency for common information while preserving user-specific processing accuracy through separate handling of private content.
Solution Approach 2:
The individual messages are segmented into common and private components before processing. The common components are extracted and combined into a unified common message for efficient group transmission, while private components are kept separate for individualized processing. This segmentation enables the system to optimize transmission efficiency for common information while maintaining processing accuracy for user-specific content through differentiated handling approaches.
